AsyncTask execute crashes app when perform it

The user must add a marker by tapping the map. My goal is to send the Name, Category, Latitude and Longitude to a SQL database. I followed this issue: How can you pass multiple primitive parameters to AsyncTask?,
but the app crashes when I hit the button which calls the shopReg.
Also, maybe there is something wrong with the communication between my app and the WampServer. I wonder if the connection URL is correct. I found on the Internet that the default WAMP localhost IP is 10.0.2.2. See the code:

Context - ctx is null and will result in crash
#Override

Toast.makeText(ctx,result,Toast.LENGTH_LONG).show();
}
backgroundTask is not used after initialisation.
BackgroundTask backgroundTask = new BackgroundTask(this);
For below async task which you execute, context - ctx is null.
new BackgroundTask(method,Name,Category,Latitude,Longitude).execute();
Please add one more parameter and pass context as well like below:
new BackgroundTask(ctx, method,Name,Category,Latitude,Longitude).execute();

Actually it was very obvious, but I didn't see it. The String method = "save";accepts only String type and I was trying to pass double with Latitude and Longitude. So I just turned doubles to Strings using;
Latitude = String.valueOf(latLng.latitude);
Longitude = String.valueOf(latLng.longitude);
Thanks for help!

onLocationChanged getting called once (Android Studio)

I am trying to detect changes in current location in my code using onLocationChanged() method but its not getting called when my location is changing.
Also I noticed from log that onConnected() is also not getting called means callbacks are not happening totally after initialization.
Attaching the code
