Thread: [SOLVED] Blank screen app crashed while booting after installation with custom content

I spent several hours to find it out so I think is worth mention about it.
Problem is happening when I wanted to use my own long term tested content.
App is crashing while booting with blank screen.

I tried several solutions, I had nearly nothing in content and it still does crashed.

Eventually I found:
Voice files

Same content I was using for Android 4 and 8 and there was no problem at all.
Now my phone that's Android 12. Exactly same content folder. As soon as I removed all voices leaving only "lua" it worked straight away, app turned ON normally.

So, if you facing phone upgrade for Android 12+ then definitely pay attention to your voice folder and not spend half of day sitting with it like me
