[Bug] Android - ApplicationInfo.LabelRes value is not set

[markmccaigue]

Description

When making a new Xamarin.Forms project, and attempting to read the LabelRes property of the ApplicationInfo object, the value is 0. When making a new Xamarin.Android project this value is set, as expected, to a non-zero value.

I noticed this because push notifications in our app were not showing a title, and after taking a look at the Airship source code, they rely on pulling the app name as a default title, from the LabelRes property of the ApplicationInfo object.

Steps to Reproduce

1. Read the LabelRes property of the ApplicationInfo object

Expected Behavior

Value is set to the resource id representing the string of the app name (label in Android Manifest)

Actual Behavior

Value is 0

Basic Information

• Version with issue: 4.6.0.7.2.6
• Last known good version: Unknown
• IDE: Visual Studio 2019
• Platform Target Frameworks:
  • Android: 10

This will crash on lauch as it's attempting to retrieve a string resource with an id of 0.

The Forms templates are using a raw string value for the application element's android:label property in the manifest rather than using a string resource as recommended in the documentation.

The Forms templates should handle this the same way as the default Xamarin.Android project and create a string resource for the label.

As a temporary workaround, when creating a new Forms project users can manually add the label as a string resource and reference that from the manifest.
