Answer 1

its from the android documentation: http://developer.android.com/guide/topics/data/data-storage.html#ExternalCache

If you're using API Level 8 or greater, use getExternalCacheDir() to open a File that represents the external storage directory where you should save cache files. If the user uninstalls your application, these files will be automatically deleted. However, during the life of your application, you should manage these cache files and remove those that aren't needed in order to preserve file space.

If you're using API Level 7 or lower, use getExternalStorageDirectory() to open a File that represents the root of the external storage, then write your cache data in the following directory:

/Android/data//cache/ The is your Java-style package name, such as "com.example.android.app".

Answer 2

If you put your data inside android/data/your.package.name it will automatically get deleted. Both on SD and on local.
