雲端點認證失敗的Android應用

Question

我有我的第一次使用在調試模式下認證的谷歌雲端點Android應用嘗試麻煩。我設置了憑據是這樣的：

credential = GoogleAccountCredential.usingAudience(this, 
      "server:client_id:long-string-i-got-from-api-console"); 
credential.setSelectedAccountName(accountName); 

然後嘗試使用這樣的：

final String LOCAL_APP_ENGINE_SERVER_URL = "http://xxx.xxx.x.xxx:8888"; 
Testdbendpoint.Builder endpointBuilder = new Testdbendpoint.Builder(
      AndroidHttp.newCompatibleTransport(), 
      new GsonFactory(), 
      credential); 
endpointBuilder.setRootUrl(LOCAL_APP_ENGINE_SERVER_URL + "/_ah/api/"); 
Testdbendpoint endpoint = endpointBuilder.build(); 
try { 
    TestDB testDB = new TestDB().setId(10101L);      
    TestDB result = endpoint.insertTestDB(testDB).execute(); //-- fails here!!!! 
} catch ... 

但嘗試失敗，我在logcat中獲取這些信息：

03-06 23：33：20.418：W/System.err的（11861）： com.google.android.gms.auth.GoogleAuthException：致未知03-06 23：33：20.418：W/System.err的（11861） ：在 com.google.android.gms。 auth.GoogleAuthUtil.getToken（Unknown Source） 03-06 23：33：20.423：W/System.err（11861）：at com.google.android.gms.auth.GoogleAuthUtil.getToken（Unknown Source） 03- 06 23：33：20.428：W/System.err的（11861）：在 com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential.getToken（GoogleAccountCredential.java:192）

Answer 1

也許你有你的Android客戶端識別錯誤的證書指紋（SHA1）？僅當您手動簽署.apk時，使用生產密鑰的指紋才能進行驗證。

註冊一個客戶端ID針對已安裝應用（Android版）與debug.keystore指紋您API Console。要獲取指紋的使用：

C:\>keytool -list -alias androiddebugkey -keystore C:\.android\debug.keystore -storepass android -keypass android 

您也需要一個Web客戶端-ID，並在你的Android應用程序設置爲聽衆：

credential = GoogleAccountCredential.usingAudience(this,"server:client_id:" + WEB_CLIENT_ID); 

AppEngine上的端點配置應該是這樣的：

@Api(
    name = "testEndpoint", 
    version = "v1", 
    clientIds = {ClientIds.WEB_ID, ClientIds.ANDROID_PRODUCTION_ID, ClientIds.ANDROID_DEBUG_ID}, 
    audiences = {ClientIds.WEB_ID}

Answer 2

只是確保，但你登記在谷歌API控制檯以及App Engine應用程序ID的客戶ID？該谷歌帳戶已添加到設備？

在這個博客上的說明可能是有用的：
