java.lang.RuntimeException : Unable to instantiate activity (unable to open DEX file)

Question

我最近在 Google Play 中发布了一个 Android 应用程序，到目前为止一切看起来都很棒， 但有一个异常(exception)(见下文)，我有时会收到控制台崩溃的消息，它只发生在某些用户身上!
我根本无法重现它。

感谢您的帮助。

检查 build.gradle、AndroidManifest.xml 和 RondaOptionsActivity.java 中的包名称是否匹配。

看起来应该是:

com.bendev.ronda.game.activity
