实施 Facebook Account Kit 和运行项目后，它显示 Firebase API 初始化失败 为

并且还从 AccountKitController 获取 空指针异常 as

使用帐户工具包 gradle 作为

compile 'com.facebook.android:account-kit-sdk:4.27.0'

和 Firebase Gradle 作为

compile 'com.google.firebase:firebase-messaging:11.0.4'

注意：从项目中删除 Account Kit 工作正常，即没有 Firebase API 初始化失败。 问题。因此可以肯定的是，firebase 和 Account kit SDK 存在冲突 (:

Answer 1

这是由于 Facebook 的 SDK 打包的 GMS 库版本与 Firebase 的不同。你可以做这样的事情来恢复运行:

compile ('com.facebook.android:account-kit-sdk:4.27.0') {
        exclude group: 'com.google.android.gms', module: 'play-services-auth-api-phone'
        exclude group: 'com.google.android.gms', module: 'play-services-auth'
    }
    compile 'com.google.android.gms:play-services-auth:11.6.0'
    compile 'com.google.firebase:firebase-messaging:11.6.0'

这实际上是将旧库热交换为与 Firebase 打包在一起的新库。它告诉 Facebook 在没有旧库的情况下进行编译，然后我们确保在之后立即将它们添加回新版本。

Answer 2

对于NullPointerException异常似乎是，Application没有先初始化，Content Providers在它之前被初始化。在 Facebook 帐户工具包 SDK 的代码中，它试图获取我的应用程序上下文。

现在的问题是，我确实在获取应用程序共享变量的应用程序 getApplicationContext() 中实现了方法 getApplicationContext()，但该变量是全局设置的，而 Facebook Account Kit sdk 代码获取的是 Null 应用程序上下文。

解决方案：在 onCreate 方法中设置共享变量而不是全局设置它解决了 Unable to get provider.

的问题

并且对于混合问题，Account Kit SDK 使用 11.0.1 版本播放服务 gradle 并且在我的项目中我有 11.0.4 这实际上不是问题，因为在编译时 gradle 需要最新的 gradle 但在我的项目中我不是指下面 gradle 正在使用哪个 Facebook Account Kit SDK。

compile 'com.google.android.gms:play-services-auth-api-phone:11.0.1'

解决方案 ：我在上面添加了 gradle 版本 11.0.4 和混合 gradle 问题已解决

compile 'com.google.android.gms:play-services-auth-api-phone:11.0.4'

并且如果我排除 play-services-auth-api-phone 模块，则 gradle 混合错误不会显示，但它不包括该模块，因为 AccountKitActivity 在下一个按钮上单击我的应用程序崩溃为
