Greetings MIT APP INVENTOR, I have an application created on the platform, all without incident, but when installing the application on devices with Android 12 to 14, the application does not run normally and closes automatically. But I install it on a device with Android 3 and it runs without incident, although ANDROID 5+ DEVICES is selected in the settings.
We would need more information:
Relevant blocks (Screen.Initialise)
Any extensions used
How different android versions are handled for file access
