Since upgrading to AS 3.4 I can no longer debug any of my apps. I have made no changes to any of the projects, I just upgraded AS. Now all I get is "Waiting for application to come online".
When I click on Run->Attach Debugger To Android Process, there are no processes to attach.
The apps load and run, but I cannot debug them.
Is there anything I can do to get the debugger working?
(I have tried clean, rebuild, invalidate cache and restart, make project and gradlew clean).
This was fixed when the next patch for Android Studio was released, back in 2019.
(Just to close this question off, old unanswered questions look untidy).
