import android.os.Environment;去定义一个变量 private final static SynchronousQueueIntent mInstallResults new SynchronousQueue();
开始去定义那个广播安装的广播 filter.addAction(com.android.packageinstaller.ACTION_SILENCE_INSTALL); filter.addAction(android.intent.action.BOOT_COMPLETED);
然后就是收到安装的广播之后应该去干什么 BroadcastReceiver mDockReceiver new BroadcastReceiver() {Overridepublic void onReceive(Context context, Intent intent) {if (Intent.ACTION_DOCK_EVENT.equals(intent.getAction())) {mDefaultDisplayPolicy.setDockMode(intent.getIntExtra(Intent.EXTRA_DOCK_STATE,Intent.EXTRA_DOCK_STATE_UNDOCKED));}else if(com.android.packageinstaller.ACTION_SILENCE_INSTALL.equals(intent.getAction())){android.util.Log.e(yanf yim,enter install_app------);Intent mIntent1 new Intent();mIntent1.setAction(com.android.install_app1);mIntent1.setComponent(new ComponentName(com.android.settings,com.android.settings.SDMountInstallReceiver));String apkFilePath intent.getStringExtra(apkFilePath);mIntent1.putExtra(path_name,apkFilePath);context.sendBroadcast(mIntent1);} 在这里就是去启动了Settings下的SDMountInstallReceiver
2、启动设置下的SDMountInstallReceiver
2.1 先去注册
代码路径 packages\apps\Settings\AndroidManifest.xml receiver android:name.SDMountInstallReceiverandroid:exportedtrueintent-filter android:priority1000 action android:namecom.android.install_app1/ action android:namecom.android.install_app2/ action android:namecom.android.install_app3//intent-filter /receiver
!--add end--2.2 安装的服务
