How to develop native android app?

How do you do the following to develop an Android app?

• 1) When the app is started, it should check if GPS is enabled or not. If it is disabled, it should pop up asking user that, GPS has to be enabled in order to use the service? 2) When the app starts( and say if GPS is on), it should directly point to current location of the mobile phone. It should be zoomed as much as the Google maps allows. Please help me how to do these. Stackoverflow allows only to post questions with code.

  You're going to want to take a look here: http://developer.android.com/guide/topics/location/strategies.html The key part is that most of the GPS pop-up should be handled for you if you put the right permissions in the manifest. You're supposed to use the Google Maps v2 API when you have this GPS location, and I've included it below. Don't read much past "maintaining a current best estimate" as you can get what you ask for in the beginning.  Ultimately these are the two lines of critical code you'll need to get working: String locationProvider = LocationManager.NETWORK_PROVIDER; // Or, use GPS location data: // String locationProvider = LocationManager.GPS_PROVIDER; locationManager.requestLocationUpdates(locationProvider, 0, 0, locationListener); And: Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider); As for a MapView, take a look at this document: https://developers.google.com/maps/documentation/android/ You want to power your map with this GPS data after you get it from the Location Manager.  Good luck and happy coding!
