【问题描述】：

在我的 android 应用程序中，编译应用程序时出错。我在最新的 android studio 中工作并使用 Firebase UI Auth 和 Firebase Database，所有版本在 App 级别的 Grade 文件中都相同，那么为什么我会收到这个错误

错误：

Build.gradle 错误所有 com.android.support 库必须使用完全相同的版本规范（混合版本会导致运行时崩溃）。找到版本 28.0.0、27.1.0、27.0.2。示例包括 com.android.support:animated-vector-drawable:28.0.0 和 com.android.support:exifinterface:27.1.0 less... (⌘F1) 有一些库或工具和库的组合是不兼容的，或者可能导致错误。一种这样的不兼容性是使用不是最新版本的 Android 支持库版本（或者特别是低于您的 targetSdkVersion 的版本）进行编译。问题 ID：GradleCompatible

【问题讨论】：

尝试升级依赖。
我什么都试过了。我正在尝试从过去 2 天开始解决这个问题，任何帮助将不胜感激@JawadAhmed
@vwadhwa3 你试过我的答案了吗？
@PeterHaddad 是的，我做到了
@vwadhwa3 成功了吗？

【解决方案1】：

添加：

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

在你的 build.gradle(module:app) 文件中的 dependencies{} 之后

【讨论】：

【解决方案2】：

只需尝试重新添加所有被抱怨的较低版本的依赖项，例如添加

implementation 'com.android.support:exifinterface:28.0.0'

同步和编译，如果有的话，也添加它。让我知道会发生什么。
