I tested with blocking some lines of function call inside of
startSensor() and stopSensor().
Then there is no failure message.
Does any expert know how to call those function in startSensor(),
stopSensor().
Please tell me how~
/**
* remoteService.java
*/
public class RemoteService extends Service {
//emit codes...
SensorManager sensorManager;
public void startSensor(){
//String service_name = Context.SENSOR_SERVICE; <---block
//sensorManager = (SensorManager)getSystemService(service_name);
<---block
//sensorManager.registerListener(accelSensorListener, <---block
//
SensorManager.SENSOR_ACCELEROMETER,SensorManager.SENSOR_DELAY_UI); <---
block
}
public void stopSensor(){
//sensorManager.unregisterListener(accelSensorListener); <---block
}
//emit codes...
}
