多個dex文件定義了Lcom/google/android/gms/auth/api/signin/internal/zzf;

Question

錯誤

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. 
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/auth/api/signin/internal/zzf; 

我得到這個錯誤，當我這兩個依賴相加：

compile 'com.google.firebase:firebase-auth:10.0.1'

compile 'com.firebaseui:firebase-ui:0.6.0'

應用的build.gradle

apply plugin: 'com.android.application' 

android { 

    compileSdkVersion 25 
    buildToolsVersion "25.0.2"emphasized text 
    defaultConfig { 
     applicationId "com.techstrategies.icall" 
     minSdkVersion 18 
     targetSdkVersion 25

     }

} 




apply plugin: 'com.google.gms.google-services' 

Answer 1

檢查official doc.
您正在使用的是錯誤的版本。

FirebaseUI Version -> Firebase/Play Services Version 

1.1.1 --> 10.0.0 or 10.0.1 
1.0.1 --> 10.0.0 or 10.0.1 
1.0.0 --> 9.8.0 
0.6.2 --> 9.8.0 
0.6.1 --> 9.6.1 
0.6.0 --> 9.6.0 

由於您使用

compile 'com.google.firebase:firebase-core:10.0.1' 

，你必須使用：

compile 'com.firebaseui:firebase-ui:1.1.1' 

或

compile 'com.firebaseui:firebase-ui:1.0.1' 

編輯：
此外，由於要添加的Firebase-UI Auth library你必須添加這個倉庫：

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

檢查doc和this issue.
