How to add background service in Geofence android

Question

I am trying to create a geofence with background service for monitor. The geofence create successfully and work when apps Activity is open but when close the app geofence not work. What should I do now. My code is:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    LocationListener {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    ref = FirebaseDatabase.getInstance().getReference("MyLocation");
    geoFire = new GeoFire(ref);
    mVerticalSeekBar = (VerticalSeekBar)findViewById(R.id.verticalSeekBar);

    setUpdateLocation();

}

Please help me to create a background service for monitor geofence from background.

just create a background service and manage background service using job scheduler to revoke android service in background . may be its work for you follow this link developer.android.com/reference/android/app/job/JobScheduler. – Runabout

Answer 1

From Android Oreo you can't create a long running service as background service. So you have to create a foreground service which the service must bind to the current Activity

Another problem is the location update. When you using geoQuery inside a service you have to update location also in the service. When a location update trigger you must pass this update to activity then only the UI can update. In my solution I am using an interface to update the UI. You can also use broadcast listeners.

When you create service and bind it to activity, then you can use Geofence inside service

 public void startService(LatLng latLng, double radius) {
        if (!isServiceRunning) {
            isServiceRunning = true;

        } else {
            Log.e(TAG, "startTimer request for an already running timer");

        }
        if (geoQuery!=null){
            geoQuery.removeAllListeners();
        }
        geoQuery = geoFire.queryAtLocation(new GeoLocation(latLng.latitude, latLng.longitude), 2f);
        geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() {
            @Override
            public void onKeyEntered(String key, GeoLocation location) {
                sendNotification("MRF", String.format("%s entered the dangerous area", key));
            }

            @Override
            public void onKeyExited(String key) {
                sendNotification("MRF", String.format("%s exit the dangerous area", key));
            }

            @Override
            public void onKeyMoved(String key, GeoLocation location) {
                Log.d("MOVE", String.format("%s move within the dangerous area [%f/%f]", key, location.latitude, location.longitude));
            }

            @Override
            public void onGeoQueryReady() {

            }

            @Override
            public void onGeoQueryError(DatabaseError error) {
                Log.d("ERROR", "" + error);
            }
        });
    }

You can call this method from your activity as

  geoService.startService(dangerous_area,2000);

This will work even if your app is destroyed.

The complete code is as follows

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {


    private GoogleMap mMap;
    //Play Service Location
    private static final int MY_PERMISSION_REQUEST_CODE = 7192;

    private Location mLastLocaiton;

    private static int UPDATE_INTERVAL = 5000;
    private static int FATEST_INTERVAL = 3000;
    private static int DISPLACEMENT = 10;


    Marker mCurrent;
    VerticalSeekBar mVerticalSeekBar;
    private static final String TAG = MapsActivity.class.getSimpleName();

    private GeoService geoService;
    private boolean serviceBound;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.



        mVerticalSeekBar = (VerticalSeekBar) findViewById(R.id.verticalSeekBar);
        mVerticalSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                mMap.animateCamera(CameraUpdateFactory.zoomTo(progress), 1500, null);
            }

            @Override

            }

can you post me full code....I am little confused in you answer. Thank you for your reply. – Presbyterate

I already added the complete code. just copy & replace entire MapsActivity into your project's MapsActivity. – Naphthyl

Default FirebaseApp is not initialized in this process com.mahmud.geotesting. Make sure to call FirebaseApp.initializeApp(Context) first. -- this error occur when run the code. – Presbyterate

I don't know what is that error. Please download full source code from my repo then run it . github.com/vinayakb73/GeoFence-GeoFire – Naphthyl

when I go to other activity and and back to the MapActivity - it gives another notification. I want one notification if enter or exit from geofence when App is active. hope you understand. Thank you for your reply. – Presbyterate

That's Because in Orea devices you can't run a background services . Only foreground services are allowed. that's why I put that notification – Naphthyl

I understand. Thank you. – Presbyterate
