Android: Geofencing is working fine when its in foreground but not working in background

I am a novice in Android development. I tried to develop an Android app which will show a Google Map with a fixed Geofence Area and the current location of the concerned person. Whenever he / she leaves or enters that particular geofence region a notification will be shown. After searching various forums and stackoverflow for ideas I somehow manged to develop the application. But I am now facing the problem that it shows the notfication about the Entry / exit of Geofence area only when the app is open. If it is minimized and swiped out it doesn't run in background. I used GeofenceTransitionsJobIntentService for geofence transition changes. I think that I had done some silly mistake so it's not working in background. So please help me out from this problem.
Here's the full code. Any ideas where I'm going wrong ? Thanks in Advance

Run Foreground service, when App goes to background. This solves your problem.

On Android 8.0 (API level 26) and higher, if an app is running in the background while monitoring a geofence, then the device responds to geofencing events every couple of minutes. To learn how to adapt your app to these response limits, see Background Location Limits.
You might need to run a sticky foreground service for your app to be running continuously.

How to send information to a service using Intent in Android

I created a service that updates the GPS coordinates and sends them to FireBase Realtime Database. The service starts when the user accesses the home page. I want to be able to send a String from an Activity to the service Class.The problem is that i can't call the getIntent() method inside of the loginToFirebase() function .
Here is the code that I tried :
The service class :
public class TrackerService extends Service {
private static final String TAG = TrackerService.class.getSimpleName();
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
buildNotification();
loginToFirebase();
}
private void buildNotification() {
String stop = "stop";
registerReceiver(stopReceiver, new IntentFilter(stop));
PendingIntent broadcastIntent = PendingIntent.getBroadcast(
this, 0, new Intent(stop), PendingIntent.FLAG_UPDATE_CURRENT);
// Create the persistent notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setContentTitle(getString(R.string.app_name))
.setContentText("Suivi de la position ...")
.setOngoing(true)
.setContentIntent(broadcastIntent)
.setSmallIcon(R.drawable.alert);
startForeground(1, builder.build());
}
protected BroadcastReceiver stopReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, "received stop broadcast");
// Stop the service when the notification is tapped
unregisterReceiver(stopReceiver);
stopSelf();
}
};
private void loginToFirebase() {
String password = "myPassword";
FirebaseAuth.getInstance().signInWithEmailAndPassword(
email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>(){
#Override
public void onComplete(Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(TAG, "firebase auth success");
requestLocationUpdates();
} else {
Log.d(TAG, "firebase auth failed");
}
}
});
}
private void requestLocationUpdates() {
LocationRequest request = new LocationRequest();
request.setInterval(30000);
request.setFastestInterval(30000);
request.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
FusedLocationProviderClient client = LocationServices.getFusedLocationProviderClient(this);
final String path = "locations" + "/" + 123;
int permission = ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION);
if (permission == PackageManager.PERMISSION_GRANTED) {
client.requestLocationUpdates(request, new LocationCallback() {
#Override
public void onLocationResult(LocationResult locationResult) {
try {
DatabaseReference ref = FirebaseDatabase.getInstance().getReference(path);
Location location = locationResult.getLastLocation();
if (location != null) {
Log.d(TAG, "location update " + location);
ref.setValue(location);
}
}catch (Exception e){
}
}
}, null);
}
}
}
The method from which I'm calling the service (In the activity ):
private void startTrackerService() {
Intent goService= new Intent(AccueilEtudiant.this,TrackerService.class);
goService.putExtra("email",getIntent().getStringExtra("email"));
startService(goService);
}
Any recommendations?

i suggest you to use persistence . in your service use data you get from sharedPreferences , and in your activity , keep updating the sharedPreferences
gps info got updated => persist to storage => use persisted gps info in Service
The Service has to read the data from the chosen storage before sending the data.

Location tracking in the background Android

I got some problems to keep a location tracking for my Android app.
The service we developed are all working, but depending on the phones and the API level, they are killed soon or later.
My purpose is to notify a user when he is getting out of a certain range, and this is working when the app is running.
This is the service that calculates when the user is in or out of the zone:
public class GeoFenceService extends BaseService {
#Inject
GeoFenceRepository geoFenceRepository;
SettingValueService settingValueService = new SettingValueService();
GeoFence geoFence;
private GeofencingClient mGeofencingClient;
PendingIntent mGeofencePendingIntent;
List<Geofence> mGeofenceList = new ArrayList<>();
public GeoFenceService() {
super();
Injector.getInstance().getAppComponent().inject(this);
}
public Observable<GeoFence> saveGeofence(GeoFence geoFence) {
if (geoFence.getId() == null)
geoFence.setId(CommonMethods.generateUuid());
commitToRealm(geoFence);
if (Application.getHasNetwork())
return geoFenceRepository.saveGeofence(geoFence);
else
return Observable.just(null);
}
public Observable<GeoFence> getGeofence() {
return geoFenceRepository.getGeofence();
}
public GeoFence getGeofenceFromRealm() {
Realm realm = Realm.getDefaultInstance();
RealmQuery<GeoFence> query = realm.where(GeoFence.class);
GeoFence result = query.findFirst();
if (result != null)
return realm.copyFromRealm(result);
return null;
}
public void initGeoFence(Context context) {
SettingValue autoCloking = settingValueService.getSettingByName("auto_clocking");
if (autoCloking != null && autoCloking.getValue().equals("true")) {
if (mGeofencingClient == null)
mGeofencingClient = LocationServices.getGeofencingClient(context);
geoFence = getGeofenceFromRealm();
if (geoFence != null) {
addGeofence(geoFence, context);
}
}
}
#SuppressLint("MissingPermission")
public void addGeofence(GeoFence geofence, Context context) {
mGeofenceList.clear();//only 1 geofence at the same time.
mGeofenceList.add(new Geofence.Builder()
// Set the request ID of the geofence. This is a string to identify this
// geofence.
.setRequestId(geofence.getId())
.setCircularRegion(
geofence.getLatitude(),
geofence.getLongitude(),
(float) geofence.getRadius()
)
.setExpirationDuration(Geofence.NEVER_EXPIRE)
.setLoiteringDelay(30000)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER |
Geofence.GEOFENCE_TRANSITION_EXIT | Geofence.GEOFENCE_TRANSITION_DWELL)
.build());
mGeofencingClient.addGeofences(getGeofencingRequest(), getGeofencePendingIntent(context));
}
private PendingIntent getGeofencePendingIntent(Context context) {
// Reuse the PendingIntent if we already have it.
if (mGeofencePendingIntent != null) {
return mGeofencePendingIntent;
}
Intent intent = new Intent(context, GeofencingService.class);
// We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when
// calling addGeofences() and removeGeofences().
mGeofencePendingIntent = PendingIntent.getService(context, 0, intent, PendingIntent.
FLAG_UPDATE_CURRENT);
return mGeofencePendingIntent;
}
private GeofencingRequest getGeofencingRequest() {
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER | GeofencingRequest.INITIAL_TRIGGER_EXIT);
builder.addGeofences(mGeofenceList);
return builder.build();
}
public void removeGeofence(Context context) {
if (mGeofencingClient != null)
mGeofencingClient.removeGeofences(getGeofencePendingIntent(context));
}
}
Even if this was working in the background we made a service to wake up the GPS of the phone every 60 sec following the advice of this question.
This is the service we made:
public class UpdateLocationService extends Service implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
private static final String TAG = "UpdateLocationService";
private static final int LOCATION_INTERVAL = 60000;
private Context mContext;
private LocationRequest locationRequest;
private GoogleApiClient googleApiClient;
private FusedLocationProviderApi fusedLocationProviderApi;
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
#Override
public void onCreate() {
Log.e(TAG, "onCreate");
mContext = this;
getLocation();
}
#Override
public void onDestroy() {
Log.e(TAG, "onDestroy");
super.onDestroy();
try {
if (googleApiClient != null) {
googleApiClient.disconnect();
}
} catch (Exception e) {
e.printStackTrace();
}
}
private void getLocation() {
locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(LOCATION_INTERVAL);
locationRequest.setFastestInterval(LOCATION_INTERVAL);
fusedLocationProviderApi = LocationServices.FusedLocationApi;
googleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
if (googleApiClient != null) {
googleApiClient.connect();
}
}
#Override
public void onConnected(Bundle arg0) {
// Location location =
fusedLocationProviderApi.getLastLocation(googleApiClient);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
fusedLocationProviderApi.requestLocationUpdates(googleApiClient, locationRequest, this);
}
#Override
public void onConnectionSuspended(int arg0) {
}
#Override
public void onLocationChanged(Location location) {
Toast.makeText(mContext, "User location :"+location.getLatitude()+" , "+location.getLongitude(), Toast.LENGTH_SHORT).show();
}
#Override
public void onConnectionFailed(ConnectionResult arg0) {
}
}
and finally this is the call in our main activity:
if (checkGpsProviderEnabled()) {
geoFenceService.initGeoFence(this);
Intent msgIntent = new Intent(this, GeofencingService.class);
startService(msgIntent);
startService(new Intent(this,UpdateLocationService.class));
}
Of course, we implement the authorization for Localisation and service déclaration in our AndroidManifest
And everything is working fine when the app isn't in the foreground
The foreground is working on some device but not all, and I wanted to know if I can do something more to force our services to run all the time in the background

Geofence Not Use Continuous Updated Coordinate

I had created a tracking apps using Firebase. The apps have 2 type user log in user's (driver & parent) with different layout and different task.
Driver user will updated their location on Firebase database continuously into their own root of their tree.
Parent user will retrieve the data continuously to be shown on map layout and geofence layout as a latlng for the geofence coordinate.
My problem is on the geofence activity. The button 'Start Geofence' will toast " Geofence Successfully Added " and it is done perfectly. But when I click the button, its seems to get the value of latlng only static position while the data are continuously updated according to the Driver user's location.
I have done testing on mock situation. My friends log in as driver and drive from location A to location B (my location) and I log in as parent to track my friends location. When I click 'Start Geofence' button, the text " Geofence Successfully Added " are successfully toasted. But my geofence alarm not trigerred when my friends are near to location B. But when I click again, the alarm are triggered.
I assume that my geofence only take the CURRENT latlng data when I press/click the button 'Start Geofence', not continuously get updated latlng data from Firebase Database.
Can someone explain me why?
I need to use the location of the driver as my geofence coordinate, so it will be a moving geofence.

Android: Firebase Update Issue When the app is in background

Hey I m going to develop an location tracker app in which, this app in client device which constantly send it location to the firebase db.
Here the problem is that it will send the data to firebase only first 3 minutes then it wont. I don't know whats happening. ?
For that even i put a log message that log message is printed perfectly even after three minutes
Any one please help on this........!
Here i attached 3 file One BackgroundLocation: Which is the service in background which will extract the device location and call the LocationReceiver which extends broadcast receiver where it will print log message and send the data to firebase through FBSender.
Thanks in advance
BackgroundLocation.java
Which runs in Background to get the location details and call the broadcast Reveiver. LocationReveiver.java

}
}
Here Which will call FBSender to send the data to firebase.
Ther real problems comes here.
It will send the data only in first three minutes then it wont send the data to firebase
For confirmation whether the control going there or not i put log message there that log message will be printed perfectly even after 3 minutes from the start of the app
Here is FBSender.Java
public class FBSender extends Service {
private String TAG = "FBSender";
private double latitude;
private double longitude;
private double speed;
private String time;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
public void put (Location location) {
latitude = location.getLatitude();
longitude = location.getLongitude();
speed = location.getSpeed();
time = DateFormat.getTimeInstance().format(new Date());
Log.e(TAG, "Entering the run ()");
final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
FirebaseDatabase database = FirebaseDatabase.getInstance();
final DatabaseReference reference = database.getReference("users/" + user.getUid() + "/vehicles");
Log.e(TAG, "I M in the middle");
Map mLocations = new HashMap();
mLocations.put("latitude", latitude);
mLocations.put("longitude", longitude);
mLocations.put("speed", speed);
mLocations.put("time", time);
reference.setValue(mLocations);
Log.e(TAG, "Exiting The run ()");
}
}

To get more information about why the database writes are not completing after 3 minutes, add a CompetionListener to your setValue():
reference.setValue(mLocations, new DatabaseReference.CompletionListener() {
#Override
public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
if (databaseError == null) {
Log.i(TAG, "onComplete: OKAY");
} else {
Log.e(TAG, "onComplete: FAILED " + databaseError.getMessage());
}
}
});
When you hit the 3 minute mark, if the callback fires with an error, such as permission failure, you can investigate why. If it stops firing at all, that probably means you've lost connection with the Firebase server. You can monitor the connection status using a listener, as described in the documentation.
