android修改源码启动指定应用

参考http://blog.csdn.net/mr_raptor/article/details/8006721　4. Android系统企业级定制

原理替换luncher

一、项目修改

将eclipse下编译好的项目如ＭyLunch2放入　

/home/proud/AndroidSource/code/packages/apps下

添加Android.mk文件，可从其他项目内复制　加以修改

修改AndroidManifest.xml去掉versioncode versionname user-sdk的信息，编译的时候会有warm，源码中带的也没有

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mylunch2"  >    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity android:name="com.test.lunch.Main" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.FS_HOME" />                <category android:name="android.intent.category.DEFAULT" />            </intent-filter>        </activity>    </application></manifest>

 <category android:name="android.intent.category.FS_HOME" />  这个是关键，第二步修改的，系统发出的只有该应用可接收到

二、修改frameWork

找到/home/proud/AndroidSource/code/frameworks/base/core/java/android/content

修改intent.java

   @SdkConstant(SdkConstantType.INTENT_CATEGORY) public static final String CATEGORY_HOME = "android.intent.category.FS_HOME";   // public static final String CATEGORY_HOME = "android.intent.category.HOME";

修改/home/proud/AndroidSource/code/frameworks/base/api　目录下对应api的.txt和current.txt

将其中的android.intent.category.HOME换成android.intent.category.FS_HOME

 field public static final java.lang.String CATEGORY_HOME = "android.intent.category.FS_HOME";

三、修改编译选项

/home/proud/AndroidSource/code/build/target/product目录下的

generic.mk文件

引入了generic_no_telephony.mk文件　

PRODUCT_PACKAGES := \    AccountAndSyncSettings \    DeskClock \    AlarmProvider \    Bluetooth \    Calculator \    Calendar \    CertInstaller \    DrmProvider \    Email \    Exchange \    Gallery2 \    LatinIME \    Launcher2 \    Music \    MusicFX \    Provision \    MyLunch2\    Phone \    QuickSearchBox \    Settings \    Sync \    SystemUI \    Updater \    CalendarProvider \    SyncProvider

在文件中添加MyLunch2\

重新编译整个项目
