由於異常導致沒有DRP密鑰：java.lang.ClassNotFoundException：com.android.webview.chromium.Drp

Question

我們在使用Genymotion仿真器運行IONIC框架的情況下運行我們的Android應用程序時出現問題，雖然它在真實硬件，一個真正的android手機。

我可以看到一個錯誤時，拋出No DRP key due to exception:java.lang.ClassNotFoundException: com.android.webview.chromium.Drp

這裏摘錄從logcat的文件的完整日誌：

Answer 1

我有這個問題，它竟然是包含一些ES6發箭的JavaScript

（）=> {...}

取出並返回匿名函數

功能（後）{...}

不再扔在Genymotion模擬器這個錯誤。 它仍然在Android Studio模擬器上，但不影響JavaScript執行。
