Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Chrome dev tools: Look at the console and network tabs for errors.

sure, i have done it but there is no error problem in my application when in debug but after i make my app to apk i can issue white blank

You can also create a debug build as an .apk that is debuggable.
