Android Question App wont install - no error in B4A....

[andyp]

Hi. Just updated to B4A 12.50 (was on 12.20 I think)....

No changes to my app.... Compiles and 'installs' with no errors (according to the B4A dialogue)

But after hitting install on the phone, it says 'app not installed'.....

I tried using the apk in an emulator (Android Studio) and after ticking a box about SDK or something (useless I know!) it works fine....

Any ideas how to debug? Thanks!

Well, sorted..... I installed the app over USB, and now it installs fine over WiFi..... strange but all working

I uninstall the app, in such situation, and it installs fine next.

Thank you - did not think of that
