Question

我有一个Google登录按钮，我不知道如何修复它：（

错误是当传递App.xaml该类是一个Activity并实现它时：

setContentView(R.layout.activity_login);

我不知道错误在哪里，但在它没问题之后:(，有人可以帮我吗？

Answer 1

确保Google的Maven存储库包含在项目的顶级build.gradle文件中：

allprojects {
    repositories {
        google()

        // If you're using a version of Gradle lower than 4.1, you must instead use:
        // maven {
        //     url 'https://maven.google.com'
        // }
    }
}

然后在您的应用级build.gradle文件中声明Google Play服务作为依赖项：

apply plugin: 'com.android.application'
    ...

    dependencies {
        compile 'com.google.android.gms:play-services-auth:11.8.0'
    }

** PS：**避免声明多个版本的播放服务依赖项，这可能会导致不匹配，从而产生您所面临的错误。

Answer 2

只需在build.gradle（app）中包含compile 'com.google.android.gms:play-services:11.0.4'依赖项。

Answer 3

您必须为Google登录添加实现“ com.google.android.gms：play-services-auth：17.0.0”。因为Google登录按钮用于Google登录。因此，您应该在gradle文件（app）中包含它的依赖项

com.google.android.gms.common.SignInButton类错误
