APP wont compile/install

I need solution for 2 problems I have with this app:
1- It compiles (android app), I can scan the QR code and install the APP but its icon do not show and only looking into android setup/applications I can find the APP and the only option is to uninstall it.
2- Due to problems with native Web_Viewer I was sugested to use NoFileHtml extention. It works OK but the extention has no block to evaluate JS and it is a requirement for my APP so I tried with the native Web_Viewer - Evaluate JS but it looks like they cannot work toguether.
Code block below.
The APP works well in tests with companion except for the evaluation of the JS code.
Assistance wellcome.
