Using LocationListener (with google play service) as service consume too much battery (Android 4.4.2) - gps

Question

I have a service that returns the current position every 30 seconds, my problem is that the service consumes about 40% of the battery. The GPS icon is always active, even if I increase the time interval. I see this problem with my Nexus 4 android 4.4.2. Once the callback OnLocationChanged is called, the GPS is awake all the time and this consumes the entire battery. With my other Phone Nexus One android 2.2.3 , I do not see this problem, the GPS turns on every 30 seconds and turns off. And I have no battery consommation. The service use Location Request, with .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY), excepted to use GPS and Network and is not the case. I thinks there is a problem with android 4.4.2 or is Google play service
Here my service code:
public class MyServiceGpsDebug extends Service implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,LocationListener
{
IBinder mBinder = new LocalBinder();
private LocationClient mLocationClient;
private LocationRequest mLocationRequest;
// Flag that indicates if a request is underway.
private boolean mInProgress;
private Boolean servicesAvailable = false;
public class LocalBinder extends Binder
{
public MyServiceGpsDebug getServerInstance()
{
return MyServiceGpsDebug.this;
}
}
#Override
public void onCreate()
{
super.onCreate();
mInProgress = false;
// Create the LocationRequest object
mLocationRequest = LocationRequest.create();
// Use high accuracy
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
// Set the update interval to 5 seconds
mLocationRequest.setInterval(Constants.UPDATE_INTERVAL);
// Set the fastest update interval to 1 second
mLocationRequest.setFastestInterval(Constants.FASTEST_INTERVAL);
servicesAvailable = servicesConnected();
mLocationClient = new LocationClient(this, this, this);
}
private boolean servicesConnected()
{
// Check that Google Play services is available
int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
// If Google Play services is available
if (ConnectionResult.SUCCESS == resultCode)
{
return true;
}
else
{
return false;
}
}
public int onStartCommand (Intent intent, int flags, int startId)
{
super.onStartCommand(intent, flags, startId);
if(!servicesAvailable || mLocationClient.isConnected() || mInProgress)
return START_STICKY;
setUpLocationClientIfNeeded();
if(!mLocationClient.isConnected() || !mLocationClient.isConnecting() && !mInProgress)
{
appendLog(DateFormat.getDateTimeInstance().format(new Date()) + ": Started", Constants.LOG_FILE);
mInProgress = true;
mLocationClient.connect();
}
return START_STICKY;

Answer 1

I have similar problem with Nexus 4. My app has a service which uses location updates (fusion location or android providers, not both). Everything works OK for all android phones but in Nexus4 after some time the phone gets hot and slow even if i kill the app (through DDMS, 100% stopped). The only solution is to kill Google play services .
I think that there is a bug in play services for nexus 4. There is a dirty solution to kill Google Play Services every 30mins for example if phone=nexus4, but i do not know if it is possible
