问题描述
尽管运行在IONIC框架上的IONIC框架构建的Android应用程序在Genymotion模拟器上运行时遇到问题，但该应用程序可以在真正的硬件(真正的android手机)上正常运行.
We are having a problem running our Android app built with IONIC framework run on Genymotion emulator, although it runs fine on a real hardware, a real android phone.
我可以看到由于异常而没有DRP密钥引发的错误:java.lang.ClassNotFoundException:com.android.webview.chromium.Drp
I can see an error thrown No DRP key due to exception:java.lang.ClassNotFoundException: com.android.webview.chromium.Drp

推荐答案
我遇到了这个问题，原来是包含一些ES6粗箭头的JavaScript
I had this issue and it turned out to be the JavaScript that contained some ES6 fat arrows
删除它们并返回匿名函数
After removing them and returning to anonymous functions
此错误不再引发Genymotion仿真器.它仍然存在于Android Studio仿真器上，但没有影响JavaScript的执行.
this error was no longer thrown on the Genymotion emulator.It was still there on the Android Studio emulator but didn't affect the JavaScript execution.
