android shortcut 快捷键 相关问题记录

快捷键的生成、删除、判断 那些方法 原生的系统一般木有问题 第三方rom 就会存在 适配问题 

一、权限：

1、manifest 文件中 添加权限 

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/><uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT"/>

</pre>下面就是关于这个权限 <p></p><p></p><pre name="code" class="html">com.android.launcher.permission.READ_SETTINGS

不同版本 不同的机型 添加的不同 

Build.VERSION.SDK_INT  < 8 :

com.android.launcher.permission.READ_SETTINGS

Build.VERSION.SDK_INT  < 19 :

com.android.launcher2.permission.READ_SETTINGS

Build.VERSION.SDK_INT  >=19 :

com.android.launcher3.permission.READ_SETTINGS

以华为为例 就需要 添加

uses-permission android:name="com.huawei.android.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.huawei.android.launcher.permission.WRITE_SETTINGS"/>

否则在下面的判断的方法里会报错出现

java.lang.SecurityException: Permission Denial: opening provider com.huawei.android.launcher.LauncherProvider from ProcessRecord (pid=17220, uid=10150)  requires com.huawei.android.launcher.permission.READ_SETTINGS or com.huawei.android.launcher.permission.WRITE_SETTINGS

这里列出大部分的平牌机对应的相应权限

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/><uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT"/><uses-permission android:name="com.android.launcher2.permission.READ_SETTINGS"/><uses-permission android:name="com.android.launcher2.permission.WRITE_SETTINGS"/><uses-permission android:name="com.android.launcher3.permission.READ_SETTINGS"/><uses-permission android:name="com.android.launcher3.permission.WRITE_SETTINGS"/><uses-permission android:name="org.adw.launcher.permission.READ_SETTINGS"/><uses-permission android:name="org.adw.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.htc.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.htc.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.qihoo360.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.qihoo360.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.lge.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.lge.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="net.qihoo.launcher.permission.READ_SETTINGS"/><uses-permission android:name="net.qihoo.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="org.adwfreak.launcher.permission.READ_SETTINGS"/><uses-permission android:name="org.adwfreak.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="org.adw.launcher_donut.permission.READ_SETTINGS"/><uses-permission android:name="org.adw.launcher_donut.permission.WRITE_SETTINGS"/><uses-permission android:name="com.huawei.launcher3.permission.READ_SETTINGS"/><uses-permission android:name="com.huawei.launcher3.permission.WRITE_SETTINGS"/><uses-permission android:name="com.fede.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.fede.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.sec.android.app.twlauncher.settings.READ_SETTINGS"/><uses-permission android:name="com.sec.android.app.twlauncher.settings.WRITE_SETTINGS"/><uses-permission android:name="com.anddoes.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.anddoes.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.tencent.qqlauncher.permission.READ_SETTINGS"/><uses-permission android:name="com.tencent.qqlauncher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.huawei.launcher2.permission.READ_SETTINGS"/><uses-permission android:name="com.huawei.launcher2.permission.WRITE_SETTINGS"/><uses-permission android:name="com.android.mylauncher.permission.READ_SETTINGS"/><uses-permission android:name="com.android.mylauncher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.ebproductions.android.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.ebproductions.android.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.oppo.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.oppo.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.lenovo.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.lenovo.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="com.huawei.android.launcher.permission.READ_SETTINGS"/><uses-permission android:name="com.huawei.android.launcher.permission.WRITE_SETTINGS"/><uses-permission android:name="telecom.mdesk.permission.READ_SETTINGS"/><uses-permission android:name="telecom.mdesk.permission.WRITE_SETTINGS"/><uses-permission android:name="dianxin.permission.ACCESS_LAUNCHER_DATA"/>

二、provider.authority为null的问题

public  boolean hasShortcut(Context context, String shortCutName){boolean has = false;final ContentResolver cr = context.getContentResolver();String AUTHORITY = getAuthorityFromPermission(context,"com.android.launcher.permission.READ_SETTINGS");final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY+ "/favorites?notify=true");// 确认content Provider中是否有快捷键信息Cursor c = cr.query(CONTENT_URI, new String[]{ "title", "iconResource" }, "title=?", new String[]{ shortCutName.trim() }, null);if (c != null && c.getCount() > 0){has = true;if (c!=null&&!c.isClosed()){c.close();}}return has;}

private  String getAuthorityFromPermission(Context context,String permission){if (permission == null)return null;List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(PackageManager.GET_PROVIDERS);if (packs != null){for (PackageInfo pack : packs){ProviderInfo[] providers = pack.providers;if (providers != null){for (ProviderInfo provider : providers){if (permission.equals(provider.readPermission))return provider.authority;if (permission.equals(provider.writePermission))return provider.authority;}}}}return null;}

通常写法 应该是这样 或者再加入这些代码：

if (TextUtils.isEmpty(AUTHORITY)){int sdkInt = Build.VERSION.SDK_INT;if (sdkInt < 8){ // Android 2.1.x(API 7)以及以下的AUTHORITY = "com.android.launcher.settings";} else if (sdkInt < 19){// Android 4.4以下AUTHORITY = "com.android.launcher2.settings";} else{// 4.4以及以上AUTHORITY = "com.android.launcher3.settings";}}

但对第三方rom来说 好像还是行不通  权限值虽然取到了 这样得到的uri 对应的cursor 依然为空 看来权限并没有获取 正确 。通过对provideInfo的遍历 我发现后缀字符串为"launcher.permission.READ_SETTINGS" 日志过滤出的权限只有一个 并且正是我想要的。以下是我对获取权限方法的些许改动

private  String getAuthorityFromPermission(Context context){List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(PackageManager.GET_PROVIDERS);if (packs != null){for (PackageInfo pack : packs){ProviderInfo[] providers = pack.providers;if (providers != null){for (ProviderInfo provider : providers){//"launcher.permission.READ_SETTINGS" 规律总结 不见得适配所有 需要测试if (!TextUtils.isEmpty(provider.readPermission)&&provider.readPermission.contains("launcher.permission.READ_SETTINGS")){return provider.authority;}}}}}return null;}

 三 、创建快捷方式  点击进入相应的程序或界面

public  void addShortCut(Context mContext){Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");shortcut.putExtra("duplicate", false);shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, mContext.getResources().getString(R.string.str_shortCutName));Parcelable shortcutIcon = Intent.ShortcutIconResource.fromContext(mContext, R.drawable.icon_shortcut);shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, shortcutIcon);Intent intent = new Intent();//ComponentName comp = new ComponentName(mContext.getPackageName(),//mContext.getPackageName() + ".ui.xx."//+ IntentTargetClass.class.getSimpleName());intent.setAction(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);intent.setClass(mContext, IntentTargetClass.class);//intent.setComponent(comp);shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, intent);mContext.sendBroadcast(shortcut);}

通常都没有问题 但个别版本 个别第三方又会出现  虽然出现了创建xxx 快捷方式的提醒 但是 手机桌面并没有快捷图标的出现 

这个时候 我把不重复创建的设置  置为true 是否已有创建 需要根据 快捷方式是否已经存在进行判断

shortcut.putExtra("duplicate", true);

另外 有的快捷方式虽已出现 但是点击快捷方式 并没有进入 我们想要进入的界面 activity

在该activity的声明里 加入  intent_filter  

 <intent-filter >                <action android:name="android.intent.action.CREATE_SHORTCUT"/>            </intent-filter>

大部分情况下都是ok了 但时仍有个别 快捷方式 图标显示正确 但是 名称并没有显示出我们赋予的 shortcutName 而是显示 app_name 例如 LG部分机型

这个问题没有解决 希望有大神 能帮助解答 

本文 属于 只知其一不知其二 的尝试解决方式  很希望 那些看Launcher 模块源码的大神们 能分享指点一二 

如有错误 欢迎指正
