android customalized [i]

Launcher 总结:

1、launcher的布局太居中，要想两边拉伸

<\packages\apps\Launcher2\res\values\dimens.xml>

  <dimen name="apps_customize_pageLayoutPaddingLeft">40dp</dimen>    <dimen name="apps_customize_pageLayoutPaddingRight">40dp</dimen>apps tab栏的宽度（Launcher2 icon 数目、大小）

\packages\apps\Launcher2\res\layout-sw720dp\workspace.xml>

    launcher:cellCountX="10"    launcher:cellCountY="6"

2、或者不想改数目：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizeTabHost.java>

    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {          mTabs.getLayoutParams().width = contentWidth + 108;

3、workspace、AppsCustomize的cell大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

 <dimen name="workspace_cell_width">110dip</dimen>    <dimen name="workspace_cell_height">110dip</dimen>    <dimen name="apps_customize_cell_width">110dp</dimen>    <dimen name="apps_customize_cell_height">110dp</dimen>

4、里面icon的大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

     <dimen name="app_icon_size">80dp</dimen>

5、workspace没有拖动，第二页第一个icon出现在第一页的最右边：

加大workspace的宽度，或间距：
workspace的paddingLeft、paddingRight：
<\packages\apps\Launcher2\res\values-sw600dp-land\dimens.xml>

 <dimen name="workspace_left_padding">50dip</dimen> <dimen name="workspace_right_padding">50dip</dimen>

workspace两屏间距：

<dimen name="workspace_page_spacing">100dp</dimen>

修改workspace的字体大小：
如果没有就添加：
<\packages\apps\Launcher2\res\values-sw480dp\styles.xml>

<style name="WorkspaceIcon.Landscape">        <item name="android:textSize">13sp</item></style>

6、加wallpaper：

1.<\packages\apps\Launcher2\res\values-sw600dp\wallpapers.xml>
加wallpaper的名字
2.<\packages\apps\Launcher2\res\drawable-nodpi>
加如wallpaper

7、gallery的widget默认添加到workspace上：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

  <!-- Middle screen [2] -->    <appwidget        launcher:packageName="com.android.gallery3d"        launcher:className="com.android.gallery3d.gadget.PhotoAppWidgetProvider"        launcher:screen="2"        launcher:x="1"        launcher:y="0"        launcher:spanX="3"        launcher:spanY="3" />

<\packages\apps\Gallery2\src\com\android\gallery3d\gadget\PhotoAppWidgetProvider.java>

 @Override    public void onUpdate(Context context,              for (int id : appWidgetIds) {                if(id == 2){                     helper.setWidget(id,WidgetDatabaseHelper.TYPE_SHUFFLE, null);                                  }    }

8、在桌面上添加网页的快捷方式：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

  <shortcut        launcher:title="@string/application_name"        launcher:icon="@drawable/ic_no_applications"        launcher:uri="http://www.aaa.com"        launcher:screen="0"        launcher:x="0"        launcher:y="3" />

9、在桌面上默认放文件夹：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

 <folder          launcher:screen="2"          launcher:x="2"          launcher:y="2"          launcher:title = "@string/application_name" >     <favorite          launcher:className="com.android.deskclock.DeskClock"          launcher:packageName="com.android.deskclock"          launcher:container="1"          launcher:x="0"          launcher:y="0" />     <favorite          launcher:className="com.android.calculator2.Calculator"          launcher:packageName="com.android.calculator2"          launcher:container="1"          launcher:x="0"          launcher:y="0" />     </folder>   

10、桌面上添加快捷方式，点击播放视频：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut launcher:title="@string/application_name" launcher:icon="@drawable/ic_launcher_application" launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end" launcher:screen="2" launcher:x="1" launcher:y="1" />

11、安装apk，显示隐藏的google play：

1.写google显示的apk:
GooglePlayShow的activity：

  ComponentName componentname = new ComponentName("com.android.vending", "com.android.vending.AssetBrowserActivity");        packagemanager.setComponentEnabledSetting(componentname, 1, 1);        componentname = new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity");        packagemanager.setComponentEnabledSetting(componentname, 2, 1);

2.<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

    } else if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {                if (!replacing) {                         if(packageName.equals("com.example.googleplayshow")){                              context.startActivity(new Intent().setComponent(new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity")).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));                         }                    op = PackageUpdatedTask.OP_ADD;                } else {                    op = PackageUpdatedTask.OP_UPDATE;                }            }

隐藏google search：
<\packages\apps\Launcher2\src\com\android\launcher2\Launcher.java>

private void setupViews() {        mSearchDropTargetBar = (SearchDropTargetBar) mDragLayer.findViewById(R.id.qsb_bar);        mSearchDropTargetBar.hideSearchBar(false);    void showWorkspace(boolean animated, Runnable onCompleteRunnable) {        //mSearchDropTargetBar.showSearchBar(wasInSpringLoadedMode);

12、widget中隐藏google play：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>
updatePackages里面添加：

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){    mWidgets.add(widget);}

13、clock的widget下部分显示不全，向上调

<\packages\amlogic\Launcher2\res\values\dimens.xml>

<dimen name="app_widget_preview_padding_top">10dp</dimen>

修改widget的text的size：
<\packages\amlogic\Launcher2\res\layout\apps_customize_widget.xml>

 <TextView xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/widget_name"     android:textSize="20sp" />

14、launcher中隐藏一个app：

需要该app的packageName，例如要隐藏settings：
<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

 private void loadAllAppsByBatch() {         apps = packageManager.queryIntentActivities(mainIntent, 0);         ResolveInfo removeApp = null;        for(ResolveInfo info:apps){    if(info.activityInfo.packageName.equals("com.android.settings")){                             removeApp = info;                        }                    }                    if(removeApp != null){                        apps.remove(removeApp);                    }

15、launcher中隐藏多个app： 红色为改动部分

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

 private void loadAllAppsByBatch() {              final PackageManager packageManager = mContext.getPackageManager();            List<ResolveInfo> apps = new ArrayList<ResolveInfo>();            List<ResolveInfo> allApps = null;            int N = Integer.MAX_VALUE;            int startIndex;            int i=0;            int batchSize = -1;            while (i < N && !mStopped) {                if (i == 0) {                    mAllAppsList.clear();                    final long qiaTime = DEBUG_LOADERS ? SystemClock.uptimeMillis() : 0;                    allApps = packageManager.queryIntentActivities(mainIntent, 0);                    for(ResolveInfo info : allApps){                        if(info.activityInfo != null                                 && !info.activityInfo.packageName.equalsIgnoreCase("com.android.email")                                && !info.activityInfo.packageName.equalsIgnoreCase("com.android.providers.downloads.ui")                                && !info.activityInfo.packageName.equalsIgnoreCase("com.adobe.flashplayer")){                            apps.add(info);                        }                    }

settings 问题总结:

1.入口，设置分屏显示

frameworks\base\core\res\res\values\bools.xml 下的

preferences_prefer_dual_pane 为true.<bool name="preferences_prefer_dual_pane">true</bool>

2.top level headers–这里可以去掉左边的headers

private void updateHeaderList(List<Header> target) {if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {   target.remove(header);}

3.默认字体：

public void readFontSizePreference(ListPreference pref) {     ActivityManagerNative.getDefault().getConfiguration()

系统的Configuration是从ActivityManagerService设置的：

<\frameworks\base\services\java\com\android\server\am\ActivityManagerService.java>mConfiguration.setToDefaults();fontScale = Float.parseFloat(SystemProperties.get("ro.fontScale","1"));

4.settings的theme:

<\packages\apps\Settings\AndroidManifest.xml>

<application android:label="@string/settings_label"            android:icon="@mipmap/ic_launcher_settings"            android:taskAffinity=""            android:theme="@android:style/Theme.Holo"            android:uiOptions="splitActionBarWhenNarrow"            android:hardwareAccelerated="true">

<\frameworks\base\core\res\res\values\themes.xml>

<style name="Theme.Holo">字体颜色<item name="textColorPrimary">@android:color/primary_text_holo_dark</item>加亮框的颜色：<item name="activatedBackgroundIndicator">@android:drawable/activated_background_holo_dark</item>触摸框的颜色：<item name="listChoiceBackgroundIndicator">@android:drawable/list_selector_holo_dark</item>左边背景：<item name="windowBackground">@android:drawable/screen_background_selector_dark</item>右边的背景：<item name="detailsElementBackground">@android:drawable/panel_bg_holo_dark</item>title的背景：<item name="actionBarStyle">@android:style/Widget.Holo.ActionBar</item>

5.设置–》开发者选项–修改后台进程限制

frameworks/base/services/java/com/android/server$

vi ./am/ActivityManagerService.java大概839行 把int mProcessLimitOverride = -1;改成4(不得超过4个进程)标准限制 对应 -1不允许后台进程 对应 0不得超过1个进程 对应 1不得超过2个进程  对应 2不得超过3个进程 对应 3

6.默认不要锁屏，设置-安全–屏幕锁定 (无)

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

 <bool name="def_lockscreen_disabled">true</bool>

7.位置服务— 默认Google的位置服务为勾选

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

<string name="def_location_providers_allowed" translatable="false">gps</string>

改成

<string name="def_location_providers_allowed" translatable="false">gps,network</string>

常用修改

一. 修改默认(Settting.apk 中选项默认值一般存在于 frameworks\base\packages\SettingsProvider\res\values\defaults.xml)

1. 默认勾选 未知来源

<bool name="def_install_non_market_apps">false</bool> 

2. 默认铃声, 通知, 闹钟 音乐

可以在system.prop 分别配置
ro.config.ringtone=Playa.ogg

（默认铃声设置，文件在/system/media/audio/ringtones 把喜欢的铃声放这里，比如123.MP3放入ringtones文件夹中，这里代码改为

ro.config.ringtone=123.mp3）

ro.config.notification_sound=regulus.ogg

（默认提示音，文件在/system/media/audio/notifications 修改方法同上）

ro.config.alarm_alert=Alarm_Beep_03.ogg

（默认闹铃，文件在/system/media/audio/alarms 修改方法同上）

3. 壁纸不跟随滑动

packages/apps/Launcher2/./src/com/Android/launcher2/Workspace.Java
大概 875行

private float wallpaperOffsetForCurrentScroll() 修改 wallpaperOffsetForCurrentScroll 的返回值。 改成 return  0.5f; 

二.隐藏或删除某项

1.去掉设置中Wifi选项

device/amlogic/xxxref/xxxref.mk 文件中

# Device specific system feature descriptionPRODUCT_COPY_FILES += \$(LOCAL_PATH)/tablet_core_hardware.xml:system/etc/permissions/tablet_core_hardware.xml \frameworks/native/data/etc/android.hardware.wifi.xml:system/etc/permissions/android.hardware.wifi.xml \ (删除)

2.去掉设置中蓝牙选项

参考 wifi。
在 tablet_core_hardware.xml 删除

 <feature name="android.hardware.bluetooth" />    这一行

3. HDMI 部分

1）去掉HDMI选项  在system.prop中 加入 ro.hdmi.autoswitch=false2）去掉480p 选项 在prop中设置 ro.hdmi480p.enable=false

4. 去掉 powerwidget 中 某一项

以去掉 gps 为例
在 packages\apps\Settings\res\layout\widget.xml 下， 移除

 <ImageView        android:layout_width="1dip"        android:layout_height="match_parent"      android:background="@drawable/appwidget_settings_divider_holo"        android:contentDescription="@null"        />    <LinearLayout        android:id="@+id/btn_bluetooth"        android:layout_width="0dip"        android:layout_weight="1"        android:layout_height="match_parent"        android:paddingTop="12dp"        android:background="@drawable/appwidget_button_center"        android:clickable="true"        android:focusable="true"        android:orientation="vertical">        <ImageView            android:id="@+id/img_bluetooth"            android:layout_width="match_parent"            android:layout_height="0dip"            android:layout_weight="1"            android:scaleType="center"            android:contentDescription="@null"            />        <ImageView            android:id="@+id/ind_bluetooth"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:scaleType="fitXY"            android:contentDescription="@null"            />    </LinearLayout>然后 

com.android.settings.widget.SettingsAppWidgetProvider.java

注释 views.setOnClickPendingIntent(R.id.btn_gps, getLaunchPendingIntent(context, BUTTON_GPS)); 这一行。

5. 去掉 Setting widget 中 某一项

以去掉 “网络共享与便携式热点” 为例
根据”网络共享与便携式热点” 这个关键词 在 values-zh_rCN 中搜索 到的 key值， 然后在AndroidManifest.xml 搜索这个 key值。 找到对于的Activity 配置
移除

 <category android:name="com.android.settings.SHORTCUT" />  这一行。

6. 修改浏览器默认浏览器模式

packages\apps\Browser\res\xml-sw600dp\advanced_preferences.xml <ListPreference       android:key="user_agent"       android:title="@string/pref_development_uastring"       android:entries="@array/pref_development_ua_choices"       android:entryValues="@array/pref_development_ua_values"       android:defaultValue="3"/>   修改 android:defaultValue="3" 具体的值参考一下选项  <string-array name="pref_development_ua_choices" translatable="false">        <item>Android</item>        <item>Desktop</item>        <item>iPhone</item>        <item>iPad</item>        <item>Froyo-N1</item>        <item>Honeycomb-Xoom</item>    </string-array>    <!-- Do not tranlsate.  Development option -->    <string-array name="pref_development_ua_values" translatable="false">        <item>0</item>        <item>1</item>        <item>2</item>        <item>3</item>        <item>4</item>        <item>5</item>

7. workspace 预置 文件夹

范例
folder 放到最前面。launcher:container 的值是folder的数据库中的id。一般从1开始。

<folder            launcher:screen="2"            launcher:x="1"            launcher:y="1"            launcher:title ="@string/application_name" >       <favorite            launcher:className="com.android.settings"            launcher:packageName="com.android.settings.Settings"            launcher:container="2"            launcher:x="0"            launcher:y="0" />       <favorite            launcher:className="com.fb.FileBrower"            launcher:packageName="com.fb.FileBrower.FileBrower"            launcher:container="2"            launcher:x="0"            launcher:y="0" />    </folder>widget 范例<appwidget        launcher:packageName="com.android.calendar"        launcher:className="com.android.calendar.widget.CalendarAppWidgetProvider"        launcher:screen="1"        launcher:x="0"        launcher:y="0"        launcher:spanX="2"        launcher:spanY="3" />快捷方式范例<favorite        launcher:packageName="com.android.settings"        launcher:className="com.android.settings.Settings"        launcher:screen="2"        launcher:x="1"        launcher:y="3" />网页快捷方式<shortcutlauncher:title="@string/custom_google"        launcher:icon="@drawable/favicon_google"        launcher:uri="http://www.google.com/"        launcher:screen="3"        launcher:x="4"        launcher:y="1"/>

8. 系统自带LatinIME 高级设置–按键音量设置 修改默认值

          java/res/values/keypress-volumes.xml<string-array name="keypress_volumes" translatable="false">         <!-- Build.HARDWARE,volume -->        <item>amlogic,0.3</item>    //加入这行。 把0.3改成自己的默认值。0.3代表30%         <item>herring,0.5</item>         <item>tuna,0.5</item>         <item>stingray,0.4</item>

9.lockscreen坐标数字时钟被遮住

请调整红色的数字：

<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_tab_unlock_land.xml>  <!-- left side: status and music -->    <RelativeLayout        android:layout_height="match_parent"        android:layout_weight="0.5"    <!-- right side -->    <RelativeLayout        android:layout_height="match_parent"        android:layout_weight="0.5"

10.在4.1上修改默认字体大小：

比如改成大：

  <frameworks\base\packages\SettingsProvider\res\values\defaults.xml><fraction name="def_font_scale">115%</fraction>

11.没有蓝牙的平台，去掉窗口小部件－设置快捷方式－拉到桌面显示的“蓝牙”选项

<\packages\apps\Settings\src\com\android\settings\OutputSettingsBroadcastReceiver.java>public void onReceive(Context context, Intent intent) {// boot completedif(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED)){                     if(!context.getPackageManager().hasSystemFeature(context.getPackageManager().FEATURE_BLUETOOTH)){                            ComponentName componentname = new ComponentName("com.android.settings", "com.android.settings.Settings$BluetoothSettingsActivity");                            context.getPackageManager().setComponentEnabledSetting(componentname, 2, 1);                     }}

11. 修改 浏览器的默认标签

分别在一下资源文件中添加自定义的标签

packages\apps\Browser\res\values\strings.xml<string-array name="bookmarks" translatable="false">        <item>Google</item>        <item>http://www.google.com/</item>        <item>Picasa</item>        <item>http://picasaweb.google.com/</item>        <item>Yahoo!</item>        <item>http://www.yahoo.com/</item>        <item>MSN</item>        <item>http://www.msn.com/</item>        <item>Twitter</item>        <item>http://twitter.com/</item>        <item>Facebook</item>        <item>http://www.facebook.com/</item>        <item>Wikipedia</item>        <item>http://www.wikipedia.org/</item>        <item>eBay</item>        <item>http://www.ebay.com/</item>        <item>CNN</item>        <item>http://www.cnn.com/</item>        <item>NY Times</item>        <item>http://www.nytimes.com/</item>        <item>ESPN</item>        <item>http://espn.com/</item>        <item>Amazon</item>        <item>http://www.amazon.com/</item>        <item>Weather Channel</item>        <item>http://www.weather.com/</item>        <item>BBC</item>        <item>http://www.bbc.co.uk/</item>    </string-array>packages\apps\Browser\res\values\bookmarks_icons.xml ，注意：这里每个网站对应一个缩略图和一个favicon<array name="bookmark_preloads">        <item>@raw/favicon_google</item>        <item>@raw/thumb_google</item>        <item>@raw/favicon_picasa</item>        <item>@raw/thumb_picasa</item>        <item>@raw/favicon_yahoo</item>        <item>@raw/thumb_yahoo</item>        <item>@raw/favicon_msn</item>        <item>@raw/thumb_msn</item>        <item>@raw/favicon_twitter</item>        <item>@raw/thumb_twitter</item>        <item>@raw/favicon_facebook</item>        <item>@raw/thumb_facebook</item>        <item>@raw/favicon_wikipedia</item>        <item>@raw/thumb_wikipedia</item>        <item>@raw/favicon_ebay</item>        <item>@raw/thumb_ebay</item>        <item>@raw/favicon_cnn</item>        <item>@raw/thumb_cnn</item>        <item>@raw/favicon_nytimes</item>        <item>@raw/thumb_nytimes</item>        <item>@raw/favicon_espn</item>        <item>@raw/thumb_espn</item>        <item>@raw/favicon_amazon</item>        <item>@raw/thumb_amazon</item>        <item>@raw/favicon_weatherchannel</item>        <item>@raw/thumb_weatherchannel</item>        <item>@raw/favicon_bbc</item>        <item>@raw/thumb_bbc</item>    </array>对应的图片在 packages\apps\Browser\res\raw

12. 锁屏界面， 解锁组件增加图标

已增加 VideoPlayer 为例，
在frameworks/base/core/res/res/drawable-hdpi 下面
添加一个对应的png图标
下面红色为增加的部分。

13. 休眠策略

修改默认的休眠策略，请参考

frameworks\base\packages\SettingsProvider\res\values\defaults.xml

<integer name="def_wifi_sleep_policy">0</integer><!--  0 == Never, 1 == Only when plugged in,2 == Always. -->   

14. Launcher 半透明

4.0， 4.1 下载附件中的patch集合— translucent.zip
如果是 4.2.2系统 ， 还需修改
Launcher/src/com/android/launcher2/Launcher.java

     mLauncherView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);     mWorkspaceBackgroundDrawable = getResources().getDrawable(R.drawable.workspace_bg);     mBlackBackgroundDrawable = new ColorDrawable(Color.BLACK); // 修改为 mBlackBackgroundDrawable = new ColorDrawable(0x7f000000);    

packages\amlogic\Launcher2\src\com\android\launcher2\Launcher.java

     mStateAnimation.addListener(new AnimatorListenerAdapter() {            boolean animationCancelled = false;            @Override            public void onAnimationStart(Animator animation) {                dispatchOnLauncherTransitionEnd(fromView, animated, false); //add                dispatchOnLauncherTransitionEnd(toView, animated, false);   //add                updateWallpaperVisibility(false);  //true 改成false                // Prepare the position                toView.setTranslationX(0.0f);                toView.setTranslationY(0.0f);                toView.setVisibility(View.VISIBLE);                toView.bringToFront();            }

15. APK 预装时无法找到lib库的问题

(1) 如果log报错是找不到lib库首先可以修改lib的路径

jb4.1\frameworks\base\core\java\android\app\NativeActivity.java

  public static final String SYSTEM_LIB_PATH = "/system/lib";           if (libraryFile.exists()) {                path = libraryFile.getPath();            }else{                File systemLibraryFile = new File(SYSTEM_LIB_PATH,System.mapLibraryName(libname));                   if (systemLibraryFile.exists()) {                    path = systemLibraryFile.getPath();                }            }    

(2)apk本身会检测检测/data/data/lib路径是否存在资源文件时方法1不适用，用第二种方法：

在项目上的mk文件 /device/amlogic/g18refg/8ref.mk 中,加上 preinstallation

PRODUCT_PACKAGES += \lights.amlogic \FileBrowser \AppInstaller \VideoPlayer \HdmiSwitch \Update \fw_env \preinstallation

将网页底部的附件 Preinstallation.zip拷贝到packages\amlogic下面解压 将需要预装安装的apk拷贝到preinstallation目录下面，编辑里面的preinstall.sh文件内容如下：

#!/system/xbin/busybox shecho "do preinstall applications"# com.mxtech.videoplayer.ad apk包名if [ ! -e /data/data/com.mxtech.videoplayer.ad/ ]; then  pm install /system/preinstall/com.mxtech.videoplayer.ad.50.apkfiif [ ! -e /data/data/org.xbmc.xbmc/ ]; then  pm install /system/preinstall/xbmc-20130414-e2c3799-Frodo-armeabi-v7a.apkfi

然后在device\amlogic\common\init\tablet\init.amlogic.rc 中,启动预安装脚本的服务.

MX:service preinstall /system/bin/preinstall.sh         class main         user root         group root         oneshot         console         disabled     M3:service preinstall /system/bin/preinstall.shuser root        group root        disabled        oneshot在init.amlogic.rc最后一行加上start preinstall

16. 去掉 hotspot

把红色的部分删掉

device\amlogic\gXXXX\overlay\frameworks\base\core\res\res\values\config.xml    <string-array translatable="false" name="config_tether_wifi_regexs">        <item>"wlap0"</item>        <item>"wl0.1"</item>        <item>"wlan0"</item>    </string-array>    <integer-array translatable="false" name="config_tether_upstream_types">        <item>0</item>        <item>9</item>    </integer-array>

17.桌面上添加快捷方式，点击播放视频：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml> <shortcutlauncher:title="@string/application_name"launcher:icon="@drawable/ic_launcher_application" launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"launcher:screen="2" launcher:x="1" launcher:y="1" />

添加网页的快捷方式：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>     <shortcut        launcher:title="@string/application_name"        launcher:icon="@drawable/ic_no_applications"        launcher:uri="http://www.aaa.com"        launcher:screen="0"        launcher:x="0"        launcher:y="3" />

18.去掉camera的全景icon：

4.1：<\packages\apps\Camera\res\layout-sw600dp-land\mode_picker.xml>        <com.android.camera.ui.RotateImageView android:id="@+id/mode_panorama"                android:contentDescription="@string/accessibility_switch_to_panorama"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:layout_weight="1"android:visibility="gone"                android:scaleType="center"                android:background="@drawable/bg_pressed"                android:src="@drawable/ic_switch_pan_holo_light" />

4.2：<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>加上红色加亮的地方：    public void init() {        for (int i = 0; i < mDrawables.length; i++) {            if ((i == LIGHTCYCLE_MODULE_INDEX && !LightCycleHelper.hasLightCycleCapture(this))||i == PANORAMA_MODULE_INDEX) {                continue; // not enabled, so don't add to UI            }            drawids[ix++] = DRAW_IDS[i];        }<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>    public void init() {        int[] drawids = new int[LightCycleHelper.hasLightCycleCapture(this)                                ? DRAW_IDS.length -1 : DRAW_IDS.length - 2];

19.锁屏左边clock太大显示不全：

<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_status_land.xml>

        <TextView android:id="@+id/timeDisplayBackground"android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"<TextView android:id="@+id/timeDisplayForeground"android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"//dimens.xml里的keyguard_pattern_unlock_clock_font_size调小

可以把clock调成居中显示，不要靠右，造成右边显示不全

<LinearLayout        xmlns:android="http://schemas.android.com/apk/res/android"        android:orientation="vertical"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:gravity="right">//改成center

20. 去掉settings的battery里面的mobile network signal显示

加上红色语句：

<\packages\apps\Settings\src\com\android\settings\fuelgauge\BatteryHistoryChart.java>

        if (!com.android.settings.Utils.isWifiOnly(getContext())) {            mHavePhoneSignal = true;        }        mHavePhoneSignal = false;      

21. 去掉待机的CRT动画

把自己项目overlay中的
frameworks/base/core/res/res/values/config.xml

<bool name="config_animateScreenLights">false</bool> 删掉 就可以了

22. 添加格式化内部sdcard

jb4.1\packages\amlogic\Settings\src\com\android\settings\deviceinfo\StorageVolumePreferenceCategory.java

       public StorageVolumePreferenceCategory(Context context, Resources resources, StorageVolume storageVolume, StorageManager storageManager, boolean isPrimary) {// Cannot format emulated storage        mAllowFormat = mStorageVolume != null && !mStorageVolume.isEmulated()&&mStorageVolume.isRemovable();        // For now we are disabling reformatting secondary external storage        // until some interoperability problems with MTP are fixed        //if (!isPrimary) mAllowFormat = false;+        if(mStorageVolume != null && mStorageVolume.getPath().equals("/storage/sdcard0")){+            mAllowFormat = true;+        }

23. 4.2 LockScreen 任何方向都可以解锁， 修改成只有向右才能解锁

4.2 Lockscreen 对应的java 文件不再是 Lockscreen, 而是KeyguardSelectorView.javaframeworks/base/core/res/res/values/arrays.xml b/core/res/res/values/arrays.xml     <array name="lockscreen_targets_unlock_only">         <item>@*android:drawable/ic_lockscreen_unlock</item>+       <item>@null</item>+       <item>@null</item>+       <item>@null</item>     </array>     <array name="lockscreen_target_descriptions_unlock_only">         <item>@*android:string/description_target_unlock</item>+       <item>@null</item>+       <item>@null</item>+       <item>@null</item>     </array>

24.android 4.2改launcher里面的icon横排的数目：

<\packages\apps\Launcher2\res\values-sw720dp\config.xml><integer name="cell_count_x">7</integer>如果改成7，hotseat里面第8个icon不见了，可以往第8个槽里面放进去，但是重启后，icon又不见了，可以这样修改：<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>                final ItemInfo occupied[][][] =                        new ItemInfo[Launcher.SCREEN_COUNT + 1][mCellCountX + 2][mCellCountY + 1]; //原来这里是+1

25. 4.2 LockScreen 解锁界面四个方向添加一个setting入口

frameworks\base\core\res\res\values/arrays.xml    <array name="lockscreen_targets_with_camera">        <item>@drawable/ic_lockscreen_unlock</item>        <item>@drawable/ic_action_assist_generic</item>        <item>@drawable/ic_lockscreen_camera</item>        <item>@drawable/ic_lockscreen_settings</item>    </array>在 frameworks\base\core\res\res\drawable 增加 ic_lockscreen_settings.xml 文件 并添加 ic_lockscreen_settings_normal.phg ic_lockscreen_settings_activated.png 资源文件<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item        android:state_enabled="true"        android:state_active="false"        android:state_focused="false"        android:drawable="@drawable/ic_lockscreen_settings_normal" />    <item        android:state_enabled="true"        android:state_active="true"        android:state_focused="false"        android:drawable="@drawable/ic_lockscreen_settings_activated" />    <item        android:state_enabled="true"        android:state_active="false"        android:state_focused="true"        android:drawable="@drawable/ic_lockscreen_settings_activated" /></selector> frameworks\base\policy\src\com\android\internal\policy\impl\LockScreen.java     public void onTrigger(View v, int target) {            final int resId = mGlowPadView.getResourceIdForTarget(target);            switch (resId) {            case com.android.internal.R.drawable.ic_lockscreen_settings: //启动setting 应用                    launchActivity(new Intent().setComponent(new ComponentName("com.android.settings","com.android.settings.Settings")));                       mCallback.pokeWakelock();                    break;

26. 4.2 上隐藏 Wifi Display

去掉项目overlay/frameworks/base/core/res/res/config.xml 中的

config_enableWifiDisplay 

27. 默认音量修改

frameworks/base/media/java/android/media/AudioService.java

private final int[] MAX_STREAM_VOLUME = new int[] {        5,  // STREAM_VOICE_CALL        7,  // STREAM_SYSTEM        7,  // STREAM_RING        15, // STREAM_MUSIC        7,  // STREAM_ALARM        7,  // STREAM_NOTIFICATION        15, // STREAM_BLUETOOTH_SCO        7,  // STREAM_SYSTEM_ENFORCED        15, // STREAM_DTMF        15  // STREAM_TTS    };

frameworks/base/media/java/android/media/AudioManager.java

/**  @hide Default volume index values for audio streams */    public static final int[] DEFAULT_STREAM_VOLUME = new int[] {        4,  // STREAM_VOICE_CALL        7,  // STREAM_SYSTEM        5,  // STREAM_RING        11, // STREAM_MUSIC        6,  // STREAM_ALARM        5,  // STREAM_NOTIFICATION        7,  // STREAM_BLUETOOTH_SCO        7,  // STREAM_SYSTEM_ENFORCED        11, // STREAM_DTMF        11  // STREAM_TTS    };

28.widget中隐藏google play：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>
updatePackages里面添加：

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){    mWidgets.add(widget);}

29.去掉设置–>显示–>亮度里的“自动调整亮度”选项

<\packages\apps\Settings\res\layout\preference_dialog_brightness.xml>

<CheckBox android:id="@+id/automatic_mode"加上android:visibility="invisible"

30.设置-位置信息访问权限默认关闭

32.设置-声音-触摸提示音与锁屏提示音默认不勾允状态

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<integer name="def_lockscreen_sounds_enabled">0</integer><bool name="def_sound_effects_enabled">false</bool>

33.设置-以太网菜单请移动“更多”菜单下

请用附件ethernet.patch，开关是ro.ethernet.more，设置为true，ethernet移到more里面
在settings的git下打这个patch

---vacant

34.窗口小部件“指针时钟”显示不全

把clock的widget向上调，下面的值改小：
<\packages\amlogic\Launcher2\res\values\dimens.xml>

<dimen name="app_widget_preview_padding_top">10dp</dimen>

35.去掉settings的more里面的网络共享与便携式热点

ro.tether.denied=true

36.平台主界面底部工具栏上的图标全部居中显示，从左至右的图标依次为：vol-、back、home、窗口切换、vol+

1.在prop里面将ro.statusbar.volume设置为true2.<\frameworks\base\packages\SystemUI\res\layout-sw600dp\navigation_bar.xml>将<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/sub"……/>这段放到<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/back"……/>这段之前<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/add"……/>这段放到<com.android.systemui.statusbar.policy.KeyButtonViewandroid:id="@+id/recent_apps"……/>这段之后注意这个文件有两处需要调换上面的

37.主界面模拟时钟改成数字时钟

default_workspace.xml里面加上：

<appwidget    launcher:packageName="com.android.deskclock"    launcher:className="com.android.alarmclock.DigitalAppWidgetProvider"

38、settings中的developer options的开关打开，debug关掉：

<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

 private void loadSecureSettings(SQLiteDatabase db) { loadSetting(stmt, Settings.Secure.ADB_ENABLED, 0); loadSetting(stmt, Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 1);

39、改桌面icon行、列数：

<\packages\apps\Launcher2\res\layout-sw***dp\workspace.xml>

    launcher:cellCountX="10"    launcher:cellCountY="6"

40、more里面morebile data项默认不选：

1.<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

 private void loadSecureSettings(SQLiteDatabase db) {   SQLiteStatement stmt = null;   try {        stmt = db.compileStatement(        "INSERT OR IGNORE INTO secure(name,value)"            +    " VALUES(?,?);");

去掉

<item>"bt-pan"</item>

44. Google play 不是内置， 而是安装，导致出问题的解决办法

frameworks/baseservices/java/com/android/server/pm/PackageManagerService.java

@@ -4594,6 +4594,9 @@ public class PackageManagerService extends IPackageManager.Stub {                             }                         }                     }+           if (pkg.packageName.equals("com.android.vending")){+                       allowed = true;+                   }            if (!allowed && (bp.protectionLevel                             & PermissionInfo.PROTECTION_FLAG_DEVELOPMENT) != 0) {                         // For development permissions, a development permission

45.以太网设置问题

以太网在settings.db中的条目是”eth_on”, 默认值由

系统属性 ro.ethernet.default_on 决定，          ro.ethernet.default_on=false 默认关闭          ro.ethernet.default_on=true默认打开不定义该属性默认关闭
