If you've tried everything above, and there are still problems, you'll need to do some diagnosis and debugging. If things break at some point in this startup, you'll need to do some further diagnosis (see below) but the first thing is to wait. Shortly after that, App Inventor should recognize that the emulator has started and start the companion in the emulator, and then load the blocks for your app.

Once the emulator gets past that, the screen will turn completely black and then come up with the Android home screen. We don't know why this is, and it might not happen all the time, but we'll keep investigating. In some cases, it can stay that way for as much as several minutes while the emulator program starts up. When the emulator starts, it first appears as a black screen with the word Android in the middle. Restarting the Companion might not solve your problem (there might be another underlying cause) but it is a good first step. Now select emulator again from the App Inventor connect drop-down menu. If the Companion tarts up again, asking about a QR code, press the menu key and kill it again. To do this, use the emulator on the computer screen: press the (image of the) menu key, and then the button to kill the app. If App Inventor has trouble communicating with the emulator, it may ask you to restart the Companion.

Part of the App Inventor software includes the App Inventor Companion app, running on the emulator.

Is App Inventor asking you to restart the companion? If you are running this or something similar, you'll need to turn it off, or configure it to not block the App Inventor connections. Is your browser running an extension that blocks connections?ДЄn example of an extension that blocks connections is the NoScript extension for Firefox. The setup software won't find the emulator support if it's in a different location.

The App Inventor directory the Commands for App Inventor software should be installed in Applications on the Mac or C:\Program Files or C:\Program Files (x86) on Windows or /usr/google on GNU/Linux. Is the setup software installed in the correct directory? Kill any running emulators before trying to start another one. Similarly, App Inventor will get confused if there is more than one emulator running. The current App Inventor 2 software can handle only a single device and will get confused if more than one device is connected. If there is a phone plugged in, then unplug it. Is there another device connected to your computer? In that case, try reduced versions of the project that have fewer screens or assets to see how large things before the problem occurs. An intermediate case is when you have a large project that has many images or sounds, or many screens. On the other hand, if the emulator won't start for any of your projects, then continue with the debugging steps here. Please submit an issue and include the project source (aia) file. If the problem is with only this project then there is probably something in the project that is tickling a bug in App Inventor. Things to check firstДoes the problem of the emulator not starting occur with just this project or with all your projects? Here are some other things to investigate as part of your debugging. When you post to the forum, describe the results of the steps you tried, so that people who want to help you will have more information about where to begin. If you eventually file an issue, first search on the forum to see if others have experienced similar problems. Please go through this procedure before filing an issue on the App Inventor forum. The issues are the same for MacOS and we will be publishing a Mac version of this document soon.) This gives a step-by-step procedure for attempting to isolate and ifix issues. If you encounter a problem connecting to the emulator, visit the pageДebugging issues in running the App Inventor Setup Tools and the emulator on Windows Symptoms you might encounter include the emulator starting up and then freezing, or not starting at all, or App Inventor displaying 'unable to connect' messages. For school computers, we've seen several issues that interfere with App Inventor, including firewalls on school networks, restrictions on software the the machines can run, and ports being blocked. There are many things that can go wrong, such as unexpected configurations, restrictions on the network you are using, or other software running on your computer that interferes with App Inventor. The process that starts the emulator involves several programs working together. The emulator should start on your computer, and connect to App Inventor so you can test your app and do live development. To use the emulator, choose Emulator from the Connect dropdown menu. App Inventor provides an Android emulator for people who do not have Android devices, or who would prefer not to use one while creating apps.
