Ok, I could install it by the command line as the image below show it. But it only works on avd 24 not on avd 28, it closes the app, when I click login, which call an http API to manage the login. In the 24 version it works ok. So the problem with the app is in Android 9, I think I follow all directions to implement projects made with b4a 8.50.
I still using the httputils2 lib
