I am working on GeoFencing in Android and I am stuck at one point. My task is to show notification to user when he enters/exits a Geofence area defined by me.
Here is my code:
Activity class
public class TestMapActivity extends FragmentActivity implements
OnMarkerDragListener,ConnectionCallbacks, OnConnectionFailedListener,OnAddGeofencesResultListener {
private static GoogleMap map;
private LocationClient mLocationClient;
private PendingIntent mGeofencePendingIntent;
private SimpleGeoFence fence;
private List<Geofence> mGeoList;
private LocationRequest localRequest;
private GeofenceReceiver mBroadcastReceiver;
private IntentFilter mIntentFilter;
@Override
protected void onCreate(Bundle saveInstance)
{
super.onCreate(saveInstance);
setContentView(R.layout.activity_map);
map = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
map.setOnMarkerDragListener(this);
CameraPosition INIT =
new CameraPosition.Builder()
.target(new LatLng(19.0222, 72.8666))
.zoom(17.5F)
.bearing(300F) // orientation
.tilt( 50F) // viewing angle
.build();
map.moveCamera( CameraUpdateFactory.newCameraPosition(INIT) );
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.add_fence:
Toast.makeText(TestMapActivity.this, "Add fence is Selected", Toast.LENGTH_LONG).show();
fence= new SimpleGeoFence();
fence.toGeofence();
addMarkerForFence(fence);
addIntentForFence();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void addMarkerForFence(SimpleGeoFence fence){
if(fence == null){
// display an error message and return
return;
}
//Instantiates a new CircleOptions object + center/radius
CircleOptions circleOptions = new CircleOptions()
.center( new LatLng(19.0216, 72.8646 ))
.radius( 500 )
.fillColor(0x40ff0000)
.strokeColor(Color.TRANSPARENT)
.strokeWidth(2);
map.addCircle(circleOptions);
map.addMarker( new MarkerOptions()
.position( new LatLng(19.0216, 72.8646) )
.title("Fence " +fence.getId())
.snippet("Radius: " +fence.getRadius()) ).showInfoWindow();
// Get back the mutable Circle
Circle circle = map.addCircle(circleOptions);
}
public void addIntentForFence()
{
Geofence geoFence= fence.toGeofence();
mGeoList = new ArrayList<Geofence>();
mGeoList.add(geoFence);
mLocationClient = new LocationClient(this, this, this);
mLocationClient.connect();
}
@Override
public void onConnected(Bundle arg0) {
// TODO Auto-generated method stub
mGeofencePendingIntent = createRequestPendingIntent();
localRequest = LocationRequest.create();
localRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
localRequest.setInterval(5000);
mLocationClient.addGeofences(mGeoList, mGeofencePendingIntent , this);
}
private PendingIntent createRequestPendingIntent() {
if (null != mGeofencePendingIntent) {
return mGeofencePendingIntent;
} else {
Intent intent = new Intent("com.example.ACTION_RECEIVE_GEOFENCE");
System.out.println("Intent" +intent);
//sendBroadcast(intent);
return PendingIntent.getBroadcast(
getApplicationContext(),
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
}
} //end oncreate
GeofenceReceiver class
public class GeofenceReceiver extends BroadcastReceiver
{
public Context context;
Intent broadcastIntent = new Intent();
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
this.context = context;
broadcastIntent.addCategory("com.example.CATEGORY_LOCATION_SERVICES");
String action= intent.getAction();
if (LocationClient.hasError(intent)) {
//do something
}
else
{
handleEnterExit(intent);
}
}
private void handleEnterExit(Intent intent) {
int transition = LocationClient.getGeofenceTransition(intent);
System.out.println("transition" +transition); //getting -1 over here
if ((transition == Geofence.GEOFENCE_TRANSITION_ENTER)
|| (transition == Geofence.GEOFENCE_TRANSITION_EXIT)) {
//send notification over here
}
}
AndroidManifest.xml container Receiver
<receiver android:name="com.example.GeofenceReceiver" android:exported="false">
<intent-filter >
<action android:name="com.example.ACTION_RECEIVE_GEOFENCE"/>
</intent-filter>
</receiver>
So basically I am able to see my GeoFence getting created but i don't get notification for the same.
does anyone have a solution for this?
