Answer 1

Just you have wrongly initialized your views. As you can only access the views after setContentView() method and you have done that totally reverse that is why its throwing error.

Just change your onCreate() as below:

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

     setContentView(R.layout.map);
   manager = (LocationManager) getSystemService(LOCATION_SERVICE);
    tvAddress = (TextView) findViewById(R.id.tvaddress);
    btncurrent= (Button)findViewById(R.id.btncurrent);
