Android지도 기본 앱이 다운 됨

Question

Google지도 애플리케이션을 구축하려고합니다 .... https://developers.google.com/maps/documentation/android/ (hello map)과 동일하게 작업하고 있습니다. 하지만 앱을 실행할 때 충돌이 발생합니다. 나는 그 문제를 일으키는 원인을 알지 못한다. 내 코드 : package com.googlemaps;

import java.io.IOException; 

import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.MapFragment; 
import com.google.android.gms.maps.SupportMapFragment; 
import com.google.android.gms.maps.model.LatLng; 
import com.google.android.gms.maps.model.MarkerOptions; 

public class MainActivity extends Activity { 

private GoogleMap maps; 

final static String URL = "http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    // Get a handle to the Map Fragment 
    maps = ((MapFragment) getFragmentManager() .findFragmentById(R.id.map)).getMap(); 
    maps.setMapType(GoogleMap.MAP_TYPE_SATELLITE); 
    LatLng as = new LatLng(141.0819,37.092); 
    maps.setMyLocationEnabled(true); 
    maps.moveCamera(CameraUpdateFactory.newLatLngZoom(as, 13)); 
    maps.addMarker(new MarkerOptions().title("PlaceName").snippet("Magnitude").position(as)); 


    }

내가 문제가이 라인의 일부 생각은 :

는

 maps.setMapType(GoogleMap.MAP_TYPE_SATELLITE); 
    LatLng as = new LatLng(141.0819,37.092); 
    maps.setMyLocationEnabled(true); 
    maps.moveCamera(CameraUpdateFactory.newLatLngZoom(as, 13)); 
    maps.addMarker(new MarkerOptions().title("PlaceName").snippet("Magnitude").position(as)); 

응용 프로그램은지도를로드 단지 이 모든 코드가 제거되면 괜찮아 ..하지만 발진 나는 아니.

Answer 1

Google 서비스의 최신 버전을 갖고 있습니까? setMapType()이 문제를 일으키고 있습니까? 그것은 oncreate에서 52 행의 널 포인터를 말합니다. 그게 뭐야?
