我正在開發一個應用程序,我需要它有一個登錄活動。我一直在關注這個(developers.google.com/identity/sign-in/android/sign-in)和this,出於某種原因,一切正常,沒有崩潰,沒有錯誤消息,但沒有登錄。安卓 - 谷歌登錄不工作(沒有崩潰或例外)

但是,每次我開始練習時我在 「運行」 選項卡中獲取這些:

W/System: ClassLoader referenced unknown path: /data/user/0/com.google.android.gms/app_chimera/m/00000008/n/armeabi-v7a 
W/System: ClassLoader referenced unknown path: /data/user/0/com.google.android.gms/app_chimera/m/00000008/n/armeabi 

和:

W/DynamiteModule: Local module descriptor class for com.google.android.gms.crash not found. 

和:

W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found. 

,並在logcat我得到:

GoogleService failed to initialize, status: 10, Missing an expected resource: 'R.string.google_app_id' for initializing Google services. Possible causes are missing google-services.json or com.google.gms.google-services gradle plugin. 

但奇怪的是我有我的app目錄中的google-services.json

我的項目gradle這個是:

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 
repositories { 
    jcenter() 
} 
dependencies { 
    classpath 'com.android.tools.build:gradle:2.2.0-alpha7' 
    classpath 'com.google.gms:google-services:2.0.0-alpha6' 
    classpath 'com.google.gms:google-services:3.0.0' 
    // NOTE: Do not place your application dependencies here; they belong 
    // in the individual module build.gradle files 
} 
}allprojects { 
repositories { 
    jcenter() 
}} 

我的模塊:應用gradle這個是:

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 24 
buildToolsVersion "21.1.2" 
defaultConfig { 
    applicationId "(My app ID)" 
    minSdkVersion 16 
    targetSdkVersion 24 
    versionCode 4 
    versionName "1.3" 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 

productFlavors { 
}} 
dependencies { 
compile fileTree(include: ['*.jar'], dir: 'libs') 
compile 'com.android.support:appcompat-v7:24.1.1' 
compile 'com.google.android.gms:play-services:9.4.0' 
compile 'com.android.support:design:24.1.1' 
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha5' 
} 
apply plugin: 'com.google.gms.google-services' 

現在,這裏是我的代碼(基於谷歌的 「整合谷歌登入到你的Android應用程序」教程):

public class Multiplayer extends AppCompatActivity implements 
GoogleApiClient.OnConnectionFailedListener, 
View.OnClickListener { 

private static final String TAG = "SignInActivity";

    // may be displayed when only basic profile is requested. Try adding the 
    // Scopes.PLUS_LOGIN scope to the GoogleSignInOptions to see the 
    // difference. 
    SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button); 
    signInButton.setSize(SignInButton.SIZE_STANDARD); 
    signInButton.setScopes(gso.getScopeArray());

     GoogleSignInResult result = opr.get(); 
     handleSignInResult(result); 
    } else { 
     // If the user has not previously signed in on this device or the sign-in has expired, 
     // this asynchronous branch will attempt to sign in the user silently. Cross-device

Here is my folder structure (I did it as rakesh kashyap suggested)

有人能幫助我嗎?我似乎無法找到問題的根源。

check ** google-services。json **文件在您的項目的應用程序文件夾中如果沒有名爲** google-services.json **的文件打開此鏈接:http://stackoverflow.com/questions/34367870/where-do-i-get-a -google-services-json –

@HarishKamboj在這個問題中,我已經提到我在我的Android應用中有google-services.json文件... – user6181605

您是否啓用了Google + api?從這裏:https://console.developers.google.com/apis/library –

您可以通過下載並按照以下步驟複製你的Android應用程序的谷歌,services.json文件解決此問題:

  • 從這個link,然後單擊選擇您的應用程序/項目名稱和Android軟件包名繼續選擇並配置服務。
  • 單擊繼續以生成配置文件。
  • 下載google-services.json並將文件複製到Android項目的應用程序/或mobile/module目錄中。

@ PN10當我把應用插件:'com.google.gms.google-services'下面應用插件:'com.android.application'及以上android {}它不會構建項目,並且在同步gradle時出現錯誤。 – user6181605

嘗試......

檢查您的構建變量(建設 - >選擇構建變量)。記下變體名稱。應該調試或發佈,或者您已經定義了什麼

選擇項目視圖。導航到應用程序 - > src並創建一個與您的構建變體名稱完全相同的目錄。

將您的JSON文件複製到此目錄。

嘗試構建 - >清理項目。檢查gradle cosole。 (解析json文件:Drive:\ path_to_your_app_dir \ your_app_name \ app \ src \ release_prod \ google-services.json )

已經複製那裏,雖然我的構建變種是調試,我應該改變它釋放? – user6181605
