A lot will depend upon the app being used and were the script is placed.
Yes, I have a rather complcated LOOP (for loop) and conditions for which is running well, but "app.alert" is ignored.
I tried a simple "Box on screen" test.
Runs fine on my PC.
On the Android the box toggles fine, but no Alert.
so far I have determined that "numFields" and "getNthFieldName" also fail.
So, which app?
Sorry, Adobe READER 11.1.3 build 86198.
Is there a better Platform for Android worth testing?
Just loaded qPDF.
It ran my Proof_of_concept version completely. Even the error handler.
