Android - Sencha Touch 2 PhoneGap issue for 4.0.x
If you are using WebView mecanism in your app, try to change for Crosswalk.
In my case, replacing interaction with android.webkit.WebView with crosswalk fixed the issue.
I don't really understand why, but Crosswalk is known for "Uniform runtime across all devices and so you don't have to deal with runtime differences on different devices running different versions of the OS. "
PhoneGap gives errors while compiling for production builds. Rather than PhoneGap use IONIC framework which under the hood run different libraries of PhoneGap but does not return such errors.
If your application is in javascript use IONIC 1.
