But today I can't get into any of the games.
I was playing games on yesterday, and things worked fine. An adb kill-server, or a kill -9, or an End Process of adb with the task manager will cause adb to die, restart, your APK installs and you're good to go isn't working. On a request to run an app, with no emulator already running, you see the Initializing ADB, then the emulator choice, it starts and you get Waiting for target to come online. If this still does not work, please report an issue Are you able to start the emulator with a blank app? If not, then you may need to hard reset the emulator: In App Inventor, select Connect > Hard Reset Confirm the reset in the dialog (this will reset your emulator image to its initially installed state) In App Inventor, select Connect > Emulator, which will start the emulator Help with problems connecting the emulato If the doesn't help, kill the emulator window, reload the browser page, and try again. Then reload the browser page, and try connecting again. Use the menu key (on the emulator) and select stop this application.
If these reconnect attempts don't work, try resetting the AI companion program.
