This tutorial assumes you have installed the SDK in the same directory as mentioned in the Tutorial for installation

Uninstalling a APK file is very simple jump into the command Prompt. ( Start -> Run-> type in “cmd” ). Now switch to the  \tools directory and run the command adb shell rm data/app/$APK where $APK is the name of the APK file.

For example: to uninstall the AndroidGlobalTime application, type in:

adb shell rm data/app/AndroidGlobalTime.apk

Note : You will need the Emulator to run to uninstall applications
