Example
I have created GeoFenceObserversationService singleton class.
GeoFenceObserversationService.java:
public class GeoFenceObserversationService extends Service implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {
protected static final String TAG = "GeoFenceObserversationService";
protected GoogleApiClient mGoogleApiClient;
protected ArrayList<Geofence> mGeofenceList;
private boolean mGeofencesAdded;
private SharedPreferences mSharedPreferences;
private static GeoFenceObserversationService mInstant;
public static GeoFenceObserversationService getInstant(){
return mInstant;
}
@Override
public void onCreate() {
super.onCreate();
mInstant = this;
mGeofenceList = new ArrayList<Geofence>();
mSharedPreferences = getSharedPreferences(AppConstants.SHARED_PREFERENCES_NAME, MODE_PRIVATE);
mGeofencesAdded = mSharedPreferences.getBoolean(AppConstants.GEOFENCES_ADDED_KEY, false);
buildGoogleApiClient();
}
@Override
public void onDestroy() {
mGoogleApiClient.disconnect();
super.onDestroy();
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
protected void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
@Override
public void onConnected(Bundle connectionHint) {
}
@Override
public void onConnectionFailed(ConnectionResult result) {
}
@Override
public void onConnectionSuspended(int cause) {
}
private GeofencingRequest getGeofencingRequest() {
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
builder.addGeofences(mGeofenceList);
return builder.build();
}
public void addGeofences() {
if (!mGoogleApiClient.isConnected()) {
Toast.makeText(this, getString(R.string.not_connected), Toast.LENGTH_SHORT).show();
return;
}
populateGeofenceList();
if(!mGeofenceList.isEmpty()){
try {
LocationServices.GeofencingApi.addGeofences(mGoogleApiClient, getGeofencingRequest(), getGeofencePendingIntent()).setResultCallback(this);
} catch (SecurityException securityException) {
securityException.printStackTrace();
}
}
}
public void removeGeofences() {
if (!mGoogleApiClient.isConnected()) {
Toast.makeText(this, getString(R.string.not_connected), Toast.LENGTH_SHORT).show();
return;
}
try {
LocationServices.GeofencingApi.removeGeofences(mGoogleApiClient,getGeofencePendingIntent()).setResultCallback(this);
} catch (SecurityException securityException) {
securityException.printStackTrace();
}
}
public void onResult(Status status) {
if (status.isSuccess()) {
mGeofencesAdded = !mGeofencesAdded;
SharedPreferences.Editor editor = mSharedPreferences.edit();
editor.putBoolean(AppConstants.GEOFENCES_ADDED_KEY, mGeofencesAdded);
editor.apply();
} else {
String errorMessage = AppConstants.getErrorString(this,status.getStatusCode());
Log.i("Geofence", errorMessage);
}
}
private PendingIntent getGeofencePendingIntent() {
Intent intent = new Intent(this, GeofenceTransitionsIntentService.class);
return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
private void populateGeofenceList() {
mGeofenceList.clear();
List<GeoFencingResponce> geoFenceList = getGeofencesList;
if(geoFenceList!=null&&!geoFenceList.isEmpty()){
for (GeoFencingResponce obj : geoFenceList){
mGeofenceList.add(obj.getGeofence());
Log.i(TAG,"Registered Geofences : " + obj.Id+"-"+obj.Name+"-"+obj.Lattitude+"-"+obj.Longitude);
}
}
}
}
AppConstant:
public static final String SHARED_PREFERENCES_NAME = PACKAGE_NAME + ".SHARED_PREFERENCES_NAME";
public static final String GEOFENCES_ADDED_KEY = PACKAGE_NAME + ".GEOFENCES_ADDED_KEY";
public static final String DETECTED_GEOFENCES = "detected_geofences";
public static final String DETECTED_BEACONS = "detected_beacons";
public static String getErrorString(Context context, int errorCode) {
Resources mResources = context.getResources();
switch (errorCode) {
case GeofenceStatusCodes.GEOFENCE_NOT_AVAILABLE:
return mResources.getString(R.string.geofence_not_available);
case GeofenceStatusCodes.GEOFENCE_TOO_MANY_GEOFENCES:
return mResources.getString(R.string.geofence_too_many_geofences);
case GeofenceStatusCodes.GEOFENCE_TOO_MANY_PENDING_INTENTS:
return mResources.getString(R.string.geofence_too_many_pending_intents);
default:
return mResources.getString(R.string.unknown_geofence_error);
}
}
Where I started Service ? From Application class
startService(new Intent(getApplicationContext(),GeoFenceObserversationService.class));
How I registered Geofences ?
GeoFenceObserversationService.getInstant().addGeofences();
