Please, please, PLEASE, never do this. Nothing requires that apps be located in
/data/data/PackageName (afaik), and if the vendor ever decides to move things
you're going to suffer a horrible flaming death.
Either use Context.FilesDir.AbsolutePath, or use
System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
they return the same value.

For sanity:
adb shell ls -l
/data/data/ShareActionProviderDemo.ShareActionProviderDemo/
What are the permissions for the `files` directory, and what is the owner &
group owner?
Also, which version of Mono for Android is this? 4.0.3 (iirc) had a bug when
deploying to the emulator wherein the `files` directory would be owned by root,
not the app, thus preventing the app from reading or writing anything to the
files directory. This should have been fixed in 4.0.4.
Thanks,
