Then, when you try to connect the emulator, the console output for aiStarter should show a sequence of "probes" of the form. There might also be problems, like a message about blocked ports, or issues with the adb program.

For a blocked port, check whether there is another program on the computer that is using the port. Is adb running correctly? The adb program can sometime get confused, especially if there are other issues. Open a console in the Commands to App Inventor directory, and run the program adbrestart and see if that helps.

Is the correct device on line? If the emulator is started and has been in the process of starting up for a while and is past the completely black screen , run the command adb devices in a console window. The result should show a list of devices: emulator device There should be exactly one device: the emulator. Disconnect any other devices.

If the status of the emulator is offline rather than connected, then you might not have waited long enough, or there might be some other program using the emulator port You'll need to find that program and disable it.

If the emulator loads and starts, but then you see an error that there is a problem communicating with the Companion, one possible but unlikely cause is that a firewall is blocking connections between App Inventor and the emulator.

Windows and MacOS both come with firewalls included with the operating system. Neither of these should create problems for App Inventor, but your computer might have other firewall software installed for example, AVG link scanner. If it does, you'll need to configure that firewall to allow both aiStarter and emulator.
