Android Question Solved - App mysteriously stopped working

[tsteward]

So I come home today and load up B4A on my PC. Load my app, change 1 line of code and hit compile.
B4A complains androidx.annotations:annotations-experimental (Google Maven) is missing. So I install it.
Now I recompile in debug mode. It compiles, it installs and blinks on my phone screen and disappears.
IDE shows no lines of anything in the log.

Not sure what to do.
I have tried loading backup from 3 days ago and same thing

Sorry for the question ahah

1) Do you have:
#BridgeLogger: True when running in release mode?

2) Try to change the package name then try to install the app.

3) Just reinstall b4a, follow the steps (don't update the sdk)

Yes I have #Bridgelogger : True
And I was thinking about re-installing but have not done that yet. Mainly because other apps will compile and work fine,

it has server passwords and everything in it

You could perhaps privately ?) share a copy of your app APK with all 'confidential' information deleted/altered.
As the fault *seems* to be in the very early initialization stages, it shouldn't affect an, hopefully, eliminatory test on some other set-ups.

Day 3 still can't get app working. I have deleted everything and reinstalled B4A & sdk as per the instructions on this website.
Result is exactly the same

I've tested your app in firebase test lab, this is the error I get, maybe you can get some clues.

"Failed resolution of: Landroid/support/v4/view/ViewConfigurationCompat; "

This error means that you are using a library that depends on Android Support Library instead of AndroidX. This is the deprecated sliding menu library. You need to jetify the library. Make sure that the library resides in the additional libraries folder.

FIXED
So lesson learnt never update sdk Although I managed to compile successfully once it was what caused my problems.
Then after reinstalling I got the error with sliding menu library that I never had before. Not sure why but don't care. I have ditched it and swapped in B4X drawer.

All is good in the work and the sun will come up tomorrow.

Thank you all for your help.
