android - 无法访问 com.google.android.gms.internal.zzbfm 的 zzbfm 类文件未找到

Question

我正在将我的 Android 应用程序项目从 GCM 迁移到 FCM。为此，我在 Android Studio 中使用了 Firebase 助手工具，并遵循了 Google 开发人员指南中的说明。一切顺利，并根据助手工具更改了我的 FCM 应用程序代码。现在，是时候运行和测试应用程序了。我得到了以下奇怪的错误:

cannot access zzbfm class file for com.google.android.gms.internal.zzbfm not found

我在使用谷歌地图并尝试设置标记位置时遇到此错误。这是我的应用级别 gradle:

为了解决您的问题，首先我会要求您始终使用指定的和更新的版本。 1. 将 + 替换为特定版本:classpath 'io.fabric.tools:gradle:1.25.4' 2. 暂时尝试使用相同版本运行apk，

  compileSdkVersion 27
  buildToolsVersion '27.0.3'

  targetSdkVersion 27
  implementation 'com.android.support:appcompat-v7:27.1.1'
  implementation 'com.android.support:support-v4:27.1.1'
  implementation 'com.android.support:recyclerview-v7:27.1.1'

3。使用更新版本的 google play 服务

 implementation 'com.google.android.gms:play-services:16.0.3'
 implementation 'com.google.android.gms:play-services-analytics:16.0.3'
 implementation 'com.google.android.gms:play-services-maps:15.0.1'

这将解决您的问题。
