I just tested my example app posted in this thread with InDe v18.0 r8, and it now works correctly without having to have the patch.
Translated from the Italian Release notes:
Update v18.0 r8
List of corrections contained in the update 18.0 r8 issued on July 31, 2018:
• As of August 1, 2018 Google requires that all new applications published on the Google Play Store have the API target at level 26 or later (the deadline is November 1 for updates to the apps already on the store).
The API level 26 forces the programmer to request the permissions to use the device's resources (GPS, camera, microphone, etc.) as they are used. and not when the application is installed. Therefore it was necessary to modify the template used by Instant Developer for the generation of the Android package.
• FFX: Due to a Firefox update, the value written in text fields was not captured if a button type field was pressed.
