android_wear_capabilities and resource shrinker

[Tolriq]

See: https://issuetracker.google.com/issues/348688201

But to resume tools:keep="@array/android_wear_capabilities" is not a valid way to ensure that the resource is kept when present inside the xml itself.
Docs should be amended with for example the solution from https://issuetracker.google.com/issues/348688201#comment4

Note to update https://developer.android.com/training/wearables/data/messages and https://developer.android.com/training/wearables/apps/standalone-apps as well

@yschimke Updating the https://developer.android.com/training/wearables/data/messages and https://developer.android.com/training/wearables/apps/standalone-apps is that internal or is that open-source as well? :)

[yschimke]

Yep, I can make those changes.

@oas004 @yschimke the PR is wrong.

The array list still needs to be in value, it's only the keep that needs to be extracted and put in the raw folder.

And BTW in the array file the "tools:keep="@array/android_wear_capabilities"" can be removed as it's the non working part it avoids mistakes.

@Tolriq Thanks, I'll follow up with a test on the release target.

@yschimke What is missing on this issue now? :) Is It something I should do? @Tolriq Does it look correct after the latest PR with adjustments? :)

[yschimke]

I just wanted to have a test that builds the release APK and confirms the resources. I'm happy to do it, but if you felt keen, go for it.

And maybe see if we can push the raw file up into library code and have apps built correctly if they just depend on horologist datalayer.
