Question

I'm trying to set up a proximity alarm based on the location of a selected marker, the coordinates for which are stored in an external file and read into an array, which in turn draws the coordinates.

    googleMap.setOnInfoWindowClickListener(
            new OnInfoWindowClickListener(){
     public void onInfoWindowClick(Marker marker) {



         LatLng clickedMarkerLatLng = marker.getPosition();
                double lat =  clickedMarkerLatLng.latitude;
                double long1 =  clickedMarkerLatLng.longitude;

            Log.e("hello", "Output=" + lat + long1);


     LocationManager lm;
    // double lat=0;
 //  double long1=0;    //Defining Latitude & Longitude
     float radius=3000;


    lm=(LocationManager) getSystemService(LOCATION_SERVICE);
    Intent i= new Intent("com.example.sleepertrain5.proximityalert");           //Custom Action
    PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), -1, i, 0);
    lm.addProximityAlert(lat, long1, radius, -1, pi);
    Toast.makeText(getBaseContext(), 
            "Info Window clicked@" + lat + "dddjdj" + long1, 
            Toast.LENGTH_SHORT).show();



    class ProximityReceiver extends android.content.BroadcastReceiver {

     @Override
     public void onReceive(Context arg0, Intent arg1) {
      // TODO Auto-generated method stub
      // The reciever gets the Context & the Intent that fired the broadcast as arg0 & agr1 

      String k=LocationManager.KEY_PROXIMITY_ENTERING;
     // Key for determining whether user is leaving or entering 

      boolean state=arg1.getBooleanExtra(k, false);
      //Gives whether the user is entering or leaving in boolean form

      if(state){
       // Call the Notification Service or anything else that you would like to do here
       Toast.makeText(arg0, "Welcome to my Area", 600).show();
      }else{
       //Other custom Notification 
       Toast.makeText(arg0, "Thank you for visiting my Area,come back again !!", 600).show();

      }

    }

    }
            }

});
}

The coordinates of the selected marker are passed to the location manager, but the proximity alarm doesn't work. Obviously at the moment, it just displays a toast, but it's not even doing that. According to the Log, the Proximity receiver class is never called, but I can't figure out why. I've tried it with varying sizes of radius and it still doesn't work. Any ideas or help?

You need to register your BroadcastReceiver with the Intents action you used for the PendingIntent. You can do this in the AndroidManifest.xml by adding these lines:

<receiver android:name="MyScheduleReceiver" >
    <intent-filter>
        <action android:name="com.example.sleepertrain5.proximityalert" />
    </intent-filter>
</receiver>
