Android應用程式升級後自動進入新版本

在新版本中建立一個Receiver接收手機應用的安裝和卸載（可以監聽到舊版本的卸載）

packagecom.justsy.lpi.receiver;importandroid.content.BroadcastReceiver;importandroid.content.Context;importandroid.content.Intent;publicclass PkInstallReceiver extends BroadcastReceiver {     @Override     public void onReceive(Context context, Intent intent) {           if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED" )) {              String packageName = intent.getDataString().substring(8);            System.out.println( "安裝:" +packageName + "包名的程式" );        }         //接收卸載廣播        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED" )) {              String packageName = intent.getDataString().substring(8);              System.out.println( "卸載:"  + packageName + "包名的程式" );            Intent newIntent =new Intent();            newIntent.setClassName(packageName,packageName+".AutoStartProTestActivity" );               newIntent.setAction("android.intent.action.MAIN");                           newIntent.addCategory("android.intent.category.LAUNCHER" );                           newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                  context.startActivity(newIntent);        }     }}

AndroidManifest.xml進行配置

         <receiver android:name="com.justsy.lpi.receiver.PkInstallReceiver"                    android:label=" @string/app_name">               <intent-filter>               <action android:name="android.intent.action.PACKAGE_ADDED" />              <action android:name="android.intent.action.PACKAGE_REMOVED" />               <data android:scheme="package" />             </intent-filter>          </receiver>      <uses-permission android:name= "android.permission.RESTART_PACKAGES" />     <uses-permission android:name= "android.permission.RECEIVE_BOOT_COMPLETED" />
