Android Dev - How to install & uninstall apk using emulator in PC

I'm newbie in Android, but I'll share what I get..

Installing Applications With Emulator Android SDK

1. I assume that you've installed sdk to your PC, and you've downloaded / created the apk. My recommendation is using Android 2.2  (API 8) because I've tried others and having some problems.
2. After created your AVD, start the emulator until you see the Android home screen (usually there's a google bar)..
3. Run your cmd, and change you directory to android-sdk/platform-tools
   ex : type "cd.." until c:\> and cd to your android-sdk folder (ex: cd DEV/android-sdk/platform-tools)
4. Move your apk to folder platform-tools
5. Type adb install yourAPK.apk and Enter
6. If success, there will be yourAPK on your Emulator's menu, just open it.
7. If you see an error that asked you to install AIR, then you have to search Runtime.apk (I got it in my flex-sdk), repeat step number 4 and install Runtime.apk
8. If success, now you can try yourAPK application..
9. Done

Uninstalling Applications With Emulator Android SDK

Press the menu button on the emulator and you will notice that the Sudoku application disappears from the main grid view.
