After building Clean.apk run java -jar unsign.jar Clean.apk
To build, use the export option in Eclipse.
$ cd into/this/repo
$ ant debug
You should now have a clean_apk-debug.apk under the bin/ directory.
Clean APK uses Instrumentation which means the app process will be running when the data is cleared. Instrumentation runs from within the app process.
Some apps may have issues with data being removed when the app is running.
