谷歌地圖API第2版的Android Studio的地圖不加載

Question

請記住，我已經通過了數以百計的像這樣類似的問題看，但我似乎劃掉已在說明書上註明所有的檢查清單如何讓Google地圖開始工作。第一

第一件事，我會告訴我的代碼，然後我會講述正在發生的事情。

主要活動

package elephant.tuskapp.activity;

public class MainActivity extends Activity {

     setContentView(R.layout.route_details); 
    } 
} 

當我運行我的應用程序，我看到在左下角的谷歌徽標一張空白的畫布。在logcat中打印出以下錯誤：

熟悉吧？你在很多其他問題中看到它。我認爲將我的問題與其他問題區分開來的原因可能是我的應用程序的不同風格有問題。

爲了避免別人遇到的錯誤，我做了以下幾件事： - 確保我的API密鑰位於清單文件的標記內。 - 確保谷歌地圖API v2 for Android在Google控制檯上啓用 - 我通過Gradle使用Google Play服務（向下滾動查看我的gradle片段） - 我確保設置了所有必要權限 - 我確保啓用glEsVersion。

我覺得這個問題是什麼？

我覺得我有我的「free.elephant.tuskapp」的味道有問題，Google的服務器進行身份驗證。在我的gradle這個身材，我保持我的應用程序的兩個不同的口味，我似乎得到與驗證的錯誤：

Ensure that the "Google Maps Android API v2" is enabled. 
Ensure that the following Android Key exists: 
API Key: myAPIKEY 
Android Application (<cert_fingerprint>;<package_name>): SHA-1;free.elephant.tuskapp 

我用「elephant.tuskapp」包名稱，而不是「免費獲得我的API .elephant.tuskapp」

這裏是我的gradle這個建立如果它的任何幫助： 搖籃

buildscript { 
     repositories { 
      maven { 
       url 'https://maven.fabric.io/public' 
      } 
     } 

     dependencies { 
      classpath 'io.fabric.tools:gradle:1.+' 
     } 
    } 
    apply plugin: 'com.android.application' 
    apply plugin: 'io.fabric' 

    repositories { 
     maven { 
      url 'https://maven.fabric.io/public' 
     } 
    } 


    android { 
     compileSdkVersion 22 
     buildToolsVersion "23.0.0 rc2" 

     defaultConfig { 
      applicationId "elephant.tuskapp" 
      minSdkVersion 15 
      targetSdkVersion 15 
     } 

     productFlavors { 
      demo { 
       applicationId "demo.elephant.tuskapp" 
      } 
      free { 
       applicationId "free.elephant.tuskapp" 
      } 
     } 

     buildTypes { 
      release { 
       minifyEnabled false 
       proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' 
      } 
     } 
    } 

    dependencies { 
     compile 'com.google.android.gms:play-services:7.5.0' 
     compile 'com.google.zxing:core:3.2.0' 
     compile('com.crashlytics.sdk.android:crashlytics:2.3.2@aar') { 
      transitive = true; 
     } 
    } 

上午我就會錯過了什麼？或者它確實與我的味道有關？如果是口味造成麻煩，我該如何處理？我爲我的所有口味生成了新的api密鑰，但是我沒有看到我應該如何在清單文件中完成這項工作，並且看起來很優雅。

Answer 1

由於我的應用程序有多種口味，我漸漸泛起，我的API密鑰並沒有被證實的錯誤。解決此問題的方法是確保將項目的所有包添加到Google Developer Console中。

SHA1;包名

然後按ENTER鍵

SHA1; packagename2（味）

在我的情況是：

SHA1;elephant.tuskapp 
SHA1;free.elephant.tuskapp 
SHA1;demo.elephant.tuskapp 

Answer 2

根據您的logcat，它說了什麼問題與您的地圖片段佈局。另外，我發現您的MainActivity中沒有任何內容，我認爲您應該在那裏初始映射。欲瞭解更多詳情，請參閱代碼here。

示例代碼：

public class MainActivity extends FragmentActivity { 

    GoogleMap mGoogleMap; 
    private static LatLng MountainView = new LatLng(37.42, -122.08); 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     // Initial Map 
     try { 

      if (mGoogleMap == null) { 
       mGoogleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     mGoogleMap.getUiSettings().setMyLocationButtonEnabled(true); 
     mGoogleMap.getUiSettings().setZoomControlsEnabled(true); 
     mGoogleMap.getUiSettings().setZoomGesturesEnabled(true); 

     mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(MountainView, 15)); 

     Marker marker = mGoogleMap.addMarker(new MarkerOptions() 
       .position(MountainView) 
       .title("Have a nice day!")); 

    } 
}
