android - 错误:(31, 32)错误:找不到符号类AuthCredential

Question

使用 firebase 时无法导入以下内容

    import com.google.firebase.auth.AuthCredential;
    import com.google.firebase.auth.AuthResult;
    import com.google.firebase.auth.FirebaseUser;

Gradle 文件

compile 'com.google.android.gms:play-services-auth:9.6.1'
compile 'com.google.firebase:firebase-database:9.2.1'
compile 'com.firebase:firebase-client-android:2.5.0'
compile 'com.google.firebase:firebase-core:9.2.0'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-config:9.4.0'
compile 'com.google.android.gms:play-services-ads:9.6.1'
compile 'com.google.firebase:firebase-crash:9.4.0'

compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'

我需要添加什么额外的东西来编译吗

尝试添加所有具有相同版本的 fire base 依赖项并且您添加了 compile 'com.google.firebase:firebase-auth:9.4.0' 依赖项它可能会与旧的依赖项产生歧义所以删除它并尝试添加新的依赖项并同步项目。这是 fire base 提供的最新依赖项。
