Debugging

At that time, when I needed to find a bug on Android, I had to build the web app, build the Android app with Cordova, launch it on a device or an emulator, launch chrome dev tool to connect to the running app, put my breakpoints, find a possible cause, fix it in my code and do this process all over again. This whole process was taking way too much time.

Plugin methods ordinarily execute in the same thread as the main interface.

but on Android:

The plugin's JavaScript does not run in the main thread of the WebView interface; instead, it runs on the WebCore thread, as does the execute method.
