Question

我有一个有限的服务，它执行TCP Socket连接并重复发送一些数据。设备进入休眠模式后，线程停止，因此数据发送。我做错了什么？

据我所知，主要活动的限制必须是repaint()，但这并不能解决我的问题。

MainActivity类，其中服务受限并且单击连接按钮会在START_STICKY中启动套接字发送线程：

AsyncTask

控制Socket连接的CTIController服务：

public class MainActivity extends AppCompatActivity {

public MainActivity() {
    super();
}

private CTIController CTIControl;
protected boolean mBound = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main); 
}

@Override
protected void onStart() {
    super.onStart();

    Intent intent = new Intent(this, CTIController.class);
    bindService(intent, mConnection, Context.BIND_AUTO_CREATE);
}

@Override
protected void onStop() {
    super.onStop();
    if (mBound) {
        //disconnect socket and stop sending thread         
        CTIControl.GetControllersFactory().GetCTI2Controller().OnDisconnect();          
        unbindService(mConnection);
        mBound = false;
    }
}

private ServiceConnection mConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        LocalBinder binder = (LocalBinder) service;
        CTIControl = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
         mBound = false;
    }
};

/** Callled when the user clicks connect button */
public void ConnectClick(View view) {                       
    new ConnectOperation().execute("");     
}

private class ConnectOperation extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... params) {
        EditText ip = (EditText)findViewById(R.id.ip);
        EditText port = (EditText)findViewById(R.id.port);

        //start socket connection and run sending thread
        CTIControl.TryConnect(ip.getText().toString(), port);

        return "Executed";
    }   
}

我的清单文件：

public class CTIController extends Service implements ICTIController {  

private final IBinder mBinder = new LocalBinder();

public TryConnect(String ipAddress, int port) throws IOException{

    this.ClientSocket = new Socket();
    this.ClientSocket.connect(new InetSocketAddress(ipAddress, port), 10000);
    //... start sending data repeatedly

}

public class LocalBinder extends Binder {
    public CTIController getService() {
        return CTIController.this;
    }
}

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

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

        return START_STICKY;
    }
}

Answer 1

更改服务的onStartCommand。

return START_REDELIVER_INTENT;代替return START_STICKY;

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

       return START_REDELIVER_INTENT;
    }
}

TCPSocket服务在设备睡眠模式下停止
