The NullPointerException is coming from mono.MonoPackageManager, which (conveniently!) enough you have on your machine; look in e.g. $(ProjectDir)\obj\Debug\android\src\MonoPackageManager.java.

MonoPackageManager.java:27:

	String filesDir = context.getFilesDir ().getAbsolutePath (); 

So either `context` is null (highly unlikely), or `context.getFilesDir()` is returning null, which is in fact possible and thus quite probable:

	https://github.com/android/platform_frameworks_base/blob/master/core/java/android/app/ContextImpl.java#L642

If this is the case, and you have access to the android debug log, you should see a message such as:

	Unable to create files directory /...

The most probable cause is that the user is running out of disk space, though a filesystem permissions issue could be at fault as well.
