When I went through this learning path myself, I had some trouble with the Android Emulator not starting up. It would usually stall at the "Android" splash screen.

 I did some research on Android communities/mailing lists and discovered that this is mainly because 1) emulator is really slow by default 2) multiple instances of emulator are being run at the same time

 A few things I would suggest you try if this happens to you: (if emulator doesn't load for over 3-5 minutes)

• Go into Task Manager/System Monitor and kill all instances of emulator
• Restart Eclipse and/or computer

Finally, you can try to run the emulator and test your Android app package from the command line.

To do that: (assuming you set up the PATHS already from the instructions)

1. Open up your command line prompt/terminal
2. Enter emulator -avd my_avd  (where my_avd is your Android emulator name)
3. Open up another command line/terminal prompt
4. Enter adb install "PATH_TO_YOUR_APK_PACKAGE" (where inside the quotes youput the file path to the built .apk file)

If you have any problems or questions, please reply!
