  • Answer:

    Use this for only GPS Provider, it does not need GPRS. locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener); <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> You need to put the permission in manifest file.

You don't need an internet connection to run GPS system in your mobile. GPS time synchronization does not require an Internet connection. But if you want to show the current location on google map, you may require internet connection. Coming to you code everything looks fine for me. Try this code in your activity. LocationManager mlocManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); LocationListener mlocListener = new YourLocationListener(getApplicationContext(), mobileNo, deviceId); mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,mlocListener); and include this in androidmanifest.xml <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> <uses-permission android:name="android.permission.ACCESS_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_GPS" /> <uses-permission android:name="android.permission.ACCESS_ASSISTED_GPS" />
