When it crashes thjen there MUST be an error in the LOG. Maybe in the unfiltered LOG.

Find it and post it.

PD: The recommended SDK is not 36

My old laptop can't keep up with polling and causing freeze issues. I crashed the app and exit the emulator. The log posted.

Click to expand...

in fact you need to return true or false in this sub.
you can just remove the sub if you don´t use it.

It crashes with return false. I forgot to add it.

I tried and I get no crashes, using and Android 36 emulator.
The app never crashes but sometimes it's sent to background, probably because the KeyBack is catched by the OS as it is not consumed by the app.
Anyway I would not spent too much time with something that maybe request a B4A update for some changes in Android 36 and that now it's not requested.

I tested it in emulator, no crash. even if there is no return value in sub keypress.
Try reinstalling the emulator.

B4X:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'return true if you want to consume the event
    Dim ph As Phone
    Log(ph.SdkVersion)
    Log("key="&KeyCode)
    Return False
End Sub

@teddybear
I wonder why you get a keycode=67 when the KeyBack should be 4, if I am correct.

I pressed the key backspace on keyborad.
Keycode 4 is ESC on my pc, there is also no crash
