问题描述
我遇到了这个问题，原来是包含一些ES6粗箭头的JavaScript
（）=> {…}
函数（）{…}
Genymotion模拟器不再抛出此错误。它仍在Android Studio仿真器上，但不影响JavaScript执行。
解决方法
我们无法运行在Genymotion模拟器上运行的基于IONIC框架构建的Android应用程序，尽管该应用程序可以在真实的硬件（真实的android手机）上正常运行。
我可以看到抛出了错误 No DRP key due to exception:java.lang.ClassNotFoundException:
com.android.webview.chromium.Drp
以下是logcat文件中完整日志的片段：
