Hi everyone,
I built an app using MIT App Inventor, but after installing it on my Android device, it only shows a black screen when launched. The app does not crash or display any error messages, but nothing appears on the screen.
It worked fine in the live test mode, but after exporting the APK/AAB file, the issue started. I have tried reinstalling the app, clearing the cache, and testing it on different devices, but the problem persists.
My app has multiple screens and uses WebViewer, Firebase, and ImagePicker extensions which might be causing the issue. I also checked my blocks and made sure the startup screen was correctly set.
Could this be related to missing permissions, an incompatible extension, or an initialization issue?
Has anyone else faced this problem, and what solutions worked for you? Any help or suggestions would be greatly appreciated. Thanks in advance!
