Hi. Usually, when I click Run-> Run 'app', AS gives me an AVD Dialog Chooser from which I can select a virtual device that I've created using the AVD Manager. It is not doing it anymore and is throwing the Edit Configuration screen instead. When I go back to the AVD Manager to start an AVD, the AVD just hangs and the cryptic message "emulator: UpdateChecker: skipped version check" I've just got my Google Maps working after a lot of work on the XML files and the project structure version combinations, I would very much like to get the chooser dialog back in order to start the AVD. P.S. Gradle build and everything else finished successfully. I was able to runt he app all the way to displaying the Google Maps. My codes could not have caused that. P.P.S. Aha, I missed the pop-up telling me "Error running app:Unable to obtain debug bridge"
