你可以使用服务
在主应用中启动/停止服务
Intent service = new Intent(context, MyService.class);context.startService(service);...Intent service = new Intent(context, MyService.class);context.stopService(service);
服务
public class MyService extends Service{ private static BroadcastReceiver m_ScreenOffReceiver; @Override public IBinder onBind(Intent arg0) { return null; } @Override public void onCreate() { registerScreenOffReceiver(); } @Override public void onDestroy() { unregisterReceiver(m_ScreenOffReceiver); m_ScreenOffReceiver = null; } private void registerScreenOffReceiver() { m_ScreenOffReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.d(TAG, "ACTION_SCREEN_OFF"); // do something, e.g. send Intent to main app } }; IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF); registerReceiver(m_ScreenOffReceiver, filter); }}
