CODE

public void open(){
        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setMessage(getApplicationContext().getResources().getString(R.string.searchFilterLocationMessage));
        alertDialogBuilder.setPositiveButton(R.string.Ok, 
                new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface arg0, int arg1) {
                /*Intent intent = new Intent(Settings.ACTION_SETTINGS) ;
                this.startActivity(intent);
                 */
                startActivityForResult(new Intent(Settings.ACTION_SETTINGS), 0);


            }
        });
        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == 0) {
            Intent intent = getIntent();
        finish();
        startActivity(intent);
        }
    }//onActivityResult

Answer 1

Launch the setting intent:

startActivity(new Intent(Settings.ACTION_SETTINGS));

and fetch the current Activity in onResume() method:

public void onResume(){
    super.onResume();
    // Do your work
}

After getting back from the setting screen, your onResume() method will be call and here you can fetch your location.
