在Chrome上调试Android WebView

1. Enable Developer Options in Device (Settings-->About Phone-->Tap 7 times on build number)
2. Turn on Developer options and Enable USB Debugging (in Developer Options)

3. Add this line in your custom Application class or in the Activity where the Web View is loaded

   // if your build is in debug mode, enable inspecting of web views

   if (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE)) {
       WebView.setWebContentsDebuggingEnabled(true);
   }
   

4. Open Chrome and type chrome://inspect/#devices and you should see your device in the Remote Target List

5. Click on inspect to debug it.

如果inspect的时候出现空白页，可能是Chrome的bug，试试用Edge，参考：https://stackoverflow.com/questions/66670000/android-chrome-inspect-devices-blank-screen
