与 android studio 调试器断开连接时后台服务停止工作（Android 磨损）

Question

我有一个片段 activity 和一个实现 SensorEventListener 的后台服务。即使屏幕关闭并在正确的参数后调用我的片段 activity ，服务也能正常工作。唯一的问题是当我断开可穿戴设备与调试器或手机的连接时（再也看不到 logcat）。服务停止工作！并且该服务不会再触发片段 activity。任何帮助都可以救命。提前致谢

public class myService extends Service implements SensorEventListener {
  private SensorManager mSensorManager;
  private Sensor mAccelerometer;
  ...
  public int onStartCommand(Intent intent, int flags, int startId) {
    //USING SENSOR MANAGER
    mSensorManager = mSensorManager) getSystemService(Context.SENSOR_SERVICE);
    mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mSensorManager.registerListener(this, mAccelerometer, mSensorManager.SENSOR_DELAY_FASTEST);
    return START_STICKY;
  }
...
public void onSensorChanged(SensorEvent event) {
  ...
  if(event.sensor.getStringType().equals(Sensor.STRING_TYPE_ACCELEROMETER)) {
    //CONVERTING VALUES
    mXValuesAcc = (float)(((int)(event.values[0] * 100)) / 100.0);
    mYValuesAcc = (float)(((int)(event.values[1] * 100)) / 100.0);
    mZValuesAcc = (float)(((int)(event.values[2] * 100)) / 100.0);

    //ADDING THREE ACCELEROMETER DATA TOGETEHR
    sumXYZ = Math.abs(mXValuesAcc) + Math.abs(mYValuesAcc) + Math.abs(mZValuesAcc);

    //MAKING READY TO CALL THE MAIN FRAGMENT ACTIVITY 
    Intent MainIntent = new Intent(this, myActivity.class);
    MainIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    //SENDING THE sumXYZ VALUE TO THE winLooseState FUNCTION
    WinLooseState winLooseState = myAlgo(sumXYZ, eventTimestamp);
    //AS A RESULT STATE OF EVENT WILL BE DEFINED

    switch (winLooseState) {
      case WIN:
        ...
        break;

      case LOOSE:
        //MAKING PowerManager READY
        PowerManager TempPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
        PowerManager.WakeLock TempWakeLock = TempPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP |
          PowerManager.ON_AFTER_RELEASE, "TempWakeLock");
        // LCD ON
        TempWakeLock.acquire();

        //DATA TO SEND TO myActivity
        MainIntent.putExtra(...);
        //CALLING myActivity                    
        startActivity(MainIntent);

        // LCD off  
        TempWakeLock.release();
        break;

      case DRAW:
        ...
    }
  }
}
}

抱歉回答晚了。所以解决方案实际上只不过是第二个 wakelock() 。当我找到解决方案时，我已经击败了自己一个星期（在我自己的脑海中）。这是一个愚蠢的错误，但当它被解决时，真是太好了:)

所以 :

@Override
public void onCreate() {    
    PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE);
    mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "systemService");
}

和 onStartCommand(..)

只需添加：

mWakelock.acquire();

所以最后有两个唤醒锁希望对您有所帮助！
