Running XDK 1995. Trying to us Debug on Android version 4.2.2.
Firstly took 2 or 3 attempts to install the latest App Preview before the app would load. Secondly App Preview is very unstable and the App does not respond correctly. Buttons are misplaced, screen refreshes are poor, sometimes resulting in a corrupt layout. Pressing buttons in the App does not respond correctly.
If I compile and install the my app it is fine, but live debugging is almost impossible.
When running inside App Preview you are running in the native Android webview. If your device is running Android 4.3 or less that webview is very deficient and is likely the reason for the behavior you are seeing. This is why we offer the Crosswalk build option, it allows you to use a modern webview on Android 4.0 and higher devices (sorry, there's nothing we can do for Android 2.x and 3.x devices). When you use the Debug tab you are running inside of a Crosswalk webview.
Use the Debug tab and build using Crosswalk. See this article http://blogs.intel.com/evangelists/2014/09/02/html5-web-app-webview-app/ and this doc page: https://software.intel.com/en-us/xdk/docs/why-use-crosswalk-for-android-...
