Description

Calling Javascript executeScript (inAppBrowser.js) WITH a callback into an inAppBrowser window kills/blurs this IAB window after the callback exits. Something like this also is mentioned in the author's comment in method 'injectDeferredObject' in 'inAppBrowser.java' on line 254.
After inverstigating, I accidentally found a work-around/solution which helped on my Android 4.4.2 Samsung Galagy Tab S.

SOLUTION:
In 'inAppBrowser.java' on line 162:

jsWrapper = String.format("prompt(JSON.stringify([eval(%%s)]), 'gap-iab://%s')", callbackContext.getCallbackId());

the 'prompt' statement should be assigned to a variable like:

jsWrapper = String.format("var r=prompt(JSON.stringify([eval(%%s)]), 'gap-iab://%s')", callbackContext.getCallbackId());

Adding 'var r=' prevents from InAppBrowser window being killed.
Don't know why. Tell me...
