谷歌地圖是不是沃金

Question

我試圖表現出google map在我的應用程序，但它顯示的小方塊盒屏幕，而不是google maps

這裏是我的Mainactivity

public class MainActivity extends FragmentActivity { 

    private static final int GPS_ERRORDIALOG_REQUEST = 9001; 
    GoogleMap mMap; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     if (servicesOK()) { 
      //Toast.makeText(this, "Google play services successfully connected.", Toast.LENGTH_SHORT).show(); 
      setContentView(R.layout.activity_map); 
     }else{ 
      setContentView(R.layout.activity_main);   
     }   
    }  

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

    public boolean servicesOK(){ 
     int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this); 
     if (isAvailable == ConnectionResult.SUCCESS) { 
      return true; 
     }else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) { 
      Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST); 
      dialog.show(); 
     }else{ 
      Toast.makeText(this, "Can't connect to google play services.", Toast.LENGTH_SHORT).show(); 
     } 
     return false; 
    }

Answer 1

你必須得到API密鑰用於這種應用

https://developers.google.com/maps/documentation/android/start#obtain_a_google_maps_api_key

在清單

<meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="08DEBUGKEYABCDEFBLAHBLAHBLAH"/> 

Answer 2

我認爲你的問題很簡單，你沒有打開在谷歌地圖api在您的谷歌conso樂網上去那裏：https://cloud.google.com/console/project 點擊你的項目，然後API和驗證，然後選擇谷歌地圖的Andorid API V2

這應該幫助:)
