广播之Android监听程序的安装和卸载

在android系统中，安装和卸载都会发送广播，当应用安装完成后系统会发android.intent.action.PACKAGE_ADDED广播。可以通过intent.getDataString()获得所安装的包名。当卸载程序时系统发android.intent.action.PACKAGE_REMOVED广播。同样intent.getDataString()获得所卸载的包名。

应用程序无法监听自己的安装与卸载，但覆盖安装可以监听到自己的android.intent.action.PACKAGE_REMOVED广播。
public class PackageReceiver extends BroadcastReceiver{

@Override

    public void onReceive(Context context, Intent intent) {       

        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {

            String packageName = intent.getDataString();

            Log.i("Test","---------------" + packageName);

        }

       

        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {

         String packageName = intent.getDataString();

          Log.i("Test","---------------" + "PACKAGE_REMOVED" + packageName);

        }

}

}
