服务在android中停止后活动关闭

服务停止时活动关闭我用来启动服务的代码是

Intent intent2 = new Intent(getApplicationContext(), TService.class);
startService(intent2);

和停止服务的代码是

 Intent intent2 = new Intent(getApplicationContext(), TService.class);
stopService(intent2);

我尝试了另一种使用绑定服务的方法,但它通过关闭活动显示了相同的行为

启动绑定服务的代码是

Intent intent2 = new Intent(getApplicationContext(), TService.class);
bindService(intent2, mServerConn, Context.BIND_AUTO_CREATE);
startService(intent2); 

&安培;停止绑定服务的代码是

stopService(new Intent(getApplicationContext(), TService.class));
unbindService(mServerConn);

我的服务TService.class

public class TService extends Service {



    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onDestroy() {
        Log.d("service", "destroy");

        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.d("TAG", "service started");
        context = getApplicationContext();
        return START_NOT_STICKY;
    }
}

我的活动MyActivity.java

public class MyActivity extends Activity{

    Button start,stop;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        start=(Button) findViewById(R.id.start);
        stop=(Button) findViewById(R.id.stop);



        final ServiceConnection mServerConn = new ServiceConnection() {
               @Override
                public void onServiceDisconnected(ComponentName name) {
                    Log.d("LOG_TAG", "onServiceDisconnected");
                }

                @Override
                public void onServiceConnected(ComponentName name, IBinder service) {
                    // TODO Auto-generated method stub
                     Log.d("LOG_TAG", "onServiceConnected");
                }
            };


        start.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent2 = new Intent(getApplicationContext(), TService.class);
                intent2.putExtra("value", "1");
                startService(intent2);

            }
        });

        stop.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub


                Intent intent2 = new Intent(getApplicationContext(), TService.class);
                intent2.putExtra("value", "2");
                stopService(intent2);


            }
        });


    }



    private int getClicks() {
        clickCount++;
        return clickCount % 2 == 0 ? R.drawable.start : R.drawable.stop;
    }

    private boolean isMyServiceRunning() {
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (TService.class.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }



    @Override
    protected void onPause() {

    }


}

我真的被困在上面,任何建议或解决方案都会被接受 提前致谢

您需要在调用stopService之前调用unbindService。我认为这就是原因。如果服务处于绑定状态,则除非它是未绑定的,否则无法停止,这可能是您的活动被关闭的原因。

代码中删除startService(intent2)以启动绑定服务。通过调用bindService(intent2, mServerConn, Context.BIND_AUTO_CREATE)无需调用startService(intent2)来绑定服务。并解除绑定服务只需使用unbindService(mServerConn)

答案 2 :(得分:0)

这是你的问题:

@Override
protected void onPause() {

}

你已经覆盖了onPause()并且你没有调用super.onPause()inside it**. This will cause your app to crash when onPause()`被调用。

你说没有堆栈跟踪,但这不正确。您可能正在过滤logcat并错过它。确保您没有过滤logcat,您将在logcat中看到错误。
