The problem is that when  you attempt to install the attached project, it fails with:


Looking at logcat, you'll find:

> W/PackageParser(24096): /data/app/vmdl-1541342243.tmp (at Binary XML file line #10): <provider> does not have valid android:name

The reason for this is that Android hates PascalCase type names, which you include in Properties\AndroidManifest.xml:

	<provider android:name="Dia.Face.DiaPadContentProvider"
		android:authorities="DiaPad.LocationProvider" />

Seriously: they validate that if android:name contains a '.', the '.' is either the first character OR that the first character is a lowercase letter:


This is why Mono for Android lowercases namespace names.

The fix is twofold:

1. Edit DiaPadContentProvider.cs, and add a [ContentProvider] custom attribute:

	class DiaPadContentProvider : ContentProvider
	// ...

2. REMOVE the <activity/> and <provider/> elements from AndroidManifest.xml; they're not needed and harmful.

The <activity/> element won't cause any compilation errors, but it will cause a second Launcher icon to be displayed, and if you tap on the "wrong" icon it'll crash during app startup (as the type Dia.Face.eventactivity won't exist).

The <provider/> element is preventing installation of your app.
