Question

嗨朋友我有一个问题需要解决...我想彻底销毁服务，一旦我从Activity调用onDestroy（）方法。但我的问题是，我无法彻底销毁它..在后台继续运行，我正在分享我尝试的示例代码..

    //Activity Class
    public class ServiceToAct extends Activity {
    private static final String TAG = "BroadcastEvent";
    private Intent intent;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        intent = new Intent(this, BroadcastService.class);
        startService(intent);
        registerReceiver(broadcastReceiver, new       IntentFilter(myService.BROADCAST_ACTION));
    }

    /*@Override
    protected void onResume() {
        super.onResume();

    }*/

    @Override
    protected void onPause() {
        super.onPause();
        unregisterReceiver(broadcastReceiver);

    }

    @Override
    protected void onDestroy() {

        stopService(intent);

        Toast.makeText(this, "Destroy Completely", Toast.LENGTH_LONG).show();
    }

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

        }
    };
}

// service class
public class myService extends Service {

    private static final String TAG = "BroadcastEvent";
    public static final String BROADCAST_ACTION = "com.service.activity.myService";
    private final Handler handler = new Handler();
    Intent intent;


    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Toast.makeText(this, "created", Toast.LENGTH_LONG).show();
        intent = new Intent(BROADCAST_ACTION);
    } 

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Toast.makeText(this, "start", Toast.LENGTH_LONG).show();
        handler.removeCallbacks(sendToUI);
        handler.postDelayed(sendToUI, 1000); 
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        stopSelf();
        //stopService(intent);
        Toast.makeText(this, "Destroy", Toast.LENGTH_LONG).show();
    }

    private Runnable sendToUI = new Runnable() {

        @Override
        public void run() {
            myData();
            handler.postDelayed(this, 10000); 
        }
    };

    private void myData() {

        Log.d(TAG, "keep on entering");
        Toast.makeText(this, "Keep on despling in UI", Toast.LENGTH_LONG).show();

        sendBroadcast(intent);
    }
}

这里实际上我想从服务更新我的UI，我的一切正常，但是如果我销毁它继续调用myData（）方法的服务，并且如果我也关闭应用程序，我将获得Toast消息。我的问题是，一旦服务被除去，我不想要那个祝酒词我使用了stopService（intent）方法来销毁服务，但是后台方法myData（）一直在调用

Answer 1

停止服务完全使用此..

<强> myActivity.java

@Override
    public void onDestroy() {
      stopService(intent); 
        super.onDestroy();
        Toast.makeText(this, "Destroy", Toast.LENGTH_LONG).show();
    }

<强> service.java

@Override
    public void onDestroy()
    {

        stopSelf();
        super.onDestroy();
    }

Answer 2

在更新UI后使用stopService（）方法

或

而不是使用startService在活动中使用bindService。当活动破坏时，服务也会破坏

Answer 3

你最好永远不要直接打电话给Xxx（）。在您的活动中使用stopService（Intent i），在您的服务中使用stopSelf（）来停止。

如何完全停止后台服务..？
