应用程序在测试人员设备上崩溃，但在我的设备上没有。我尝试安装 appmetrica 插件，但它不起作用，appmetrica 控制台的统计信息为空并且此错误位于上方。

我找不到这个错误的解决方案。能否请您给出永久解决方案。我不知道如何解决它你能帮我吗？谢谢对不起我的英语。

最佳答案

您能否提供有关发生崩溃的设备(型号、操作系统版本)的更多信息？看起来问题可能与混淆或多 dex 有关。

关于java - ClassNotFoundException:没有找到类 "com.yandex.metrica.MetricaEventHandler"。统一插件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42834411/
