Default workspace widgets not being inflated

[Roboe]

Inherited from #16.

Since Android 4.1, the BIND_APPWIDGET needs explicit permission to load a widget, as stated in the Android docs: https://developer.android.com/guide/topics/appwidgets/host#binding-41 ^{(which IMHO is a little inconsistent with how permissions are asked from Android 6 onwards, but whatever)}

The default workspace configuration includes widgets from our package (community.fairphone.fplauncher3) and from external packages (community.fairphone.mycontacts). Neither of them is added by default.

Seems like Workspace.java handles inflating shortcuts and widgets from XML files.

I'm starting to think this is impossible for third-party launchers...

Not for use by third-party applications.

The only way around this is for system apps to request android.permission.BIND_APPWIDGET in their manifest, so this method is only available on rooted devices where the app is installed at the system level (in /system/app or /system/priv-app).
