Trying to comile the HelloAndroid example from here: Hello, World | Android Developers

It says it should install and run automatically when run, but for me, it doesn't. The emulator boots up to a lock screen and stays there. Nothing happens when you unlock it. It doesn't appear in the applications drawer.

"Launch default activity" is set in the run configurations dialog.

Anything else I can check?

Many thanks in advance.

I have also tried manually setting my activity to launch in the run configuration dialog but that doesn't launch anything either.

Well, I fixed it by following the advice here: Troubleshooting | Android Developers

While the emulator was running, I ran the command:

and then it said to run another command to restart the server so I did

It then said the ADB server was out of date, killed it and restarted it. The emulator appeared in the adb devices list. It also appeared in DDMS. Re-ran the activity without closing the emulator and it loaded. Hurrah!
