This post is more of a self-remainder but hopefully it will help other mobile developers with the same issue, when working with the Android Emulator You might be in the situation that You’ll need to wipe Your app entirely and there’s no drag and drop in thrash when using the emulator, so in order to delete Your app without erasing Your AVD image just follow the next steps:
1.- Start Your Eclipse IDE (FDT or Flash Builder).
2.- Run the emulator.
3.- Using the terminal navigate to the Android SDK “platform-tools” directory, mine is located at:
4.- Do the command “./adb shell” remember that commands must have the “./” before the command name otherwise You’ll get a bash error (-bash: adb: command not found).
5.- Navigate to the app directory using the cd command ” cd /data/app/”.
6.- Then list the apps using the list command “ls” (This will display the names of the .APKs installed in Your emulator.
7.- Then use the remove command “rm YourApp.apk”
8.- You can now type “Exit” to leave the adb shell, relaunch the emulator and Your app will be gone for good.
