Somehow, I have deleted the code for the sample apps from the workspace, but the apps still show up in the android emulator. How do I delete them?
In AndroidStudio (at least in v0.9.9) you can wipe data from a AVM. Go to Tools - Android - AVD Manager and in the menu for an AVM select "wipe data".
Before starting emulator check on wipe user data
1). go to settings in emulator 2). go to storage use 3). click on your application. 4). select uninstall

ADB lets you uninstall applications. Just go:
adb uninstall <package>
You can find ADB in the tools folder of the Android SDK.
Inside the emulator go to the Settings app, then Applications -> Manage Applications -- you can delete them from there.
