App working fine when developing (using Companion) won't start when regularly installed

[Maurizio Romano]

Hi, the title is probably self explanatory, I just would like to add that the app does start but seemingly it is aborted by Android for some reason before it loads the first (and one) screen. Have anyone seen something like that before? Any tip to fix it?

The mobile phone on which I do not manage to make the app run is a Huawey P9 lite (Nougat)

Please, feel free to import and modify the Minipiano.aia file, just remember to set the global variable path to "file:///mnt/sdcard/AppInventor/assets/" in order to make the app run with Companion and to set it to "file:///android_asset/" before you build the apk file.

The disabled blocks are an attempt to fix the 703 issue but I could not try them because error 703 only occurs when the app is installed.
