java.lang.NoClassDefFoundError : Failed resolution of: Lcom/google/android/gms/common/util/zzt; 错误

Question

请帮我解决这个错误。

我的应用程序每次在设备中首次安装时都会崩溃。重新打开应用程序后，它运行正常。

我无法解决这个错误。请让我知道代码中有什么问题。提前致谢

Answer 1

因为我尝试了很多方法来解决这个错误，通过更新我所有的播放服务和 firebase Gradle 依赖项，添加 Multidex 文件，但我仍然面临同样的问题，但是在我的 app.gradle 中添加以下行之后。问题已解决。

implementation 'com.google.android.gms:play-services-gcm:16.1.0'
