Add missing TvContractCompat.WatchNextPrograms class to TvProvider binding

[Copilot]

TvContractCompat.WatchNextPrograms is missing from Xamarin.AndroidX.TvProvider 1.1.0.2+. The Java class exists in the AAR but is dropped during binding generation because it contains only static final fields (no constructors/methods) — the generator treats it as empty and removes it.

Changes

• Metadata.xml (source/androidx.tvprovider/tvprovider/Transforms/Metadata.xml): Uses add-node to define TvContractCompat.WatchNextPrograms with a package-private constructor, which prevents the binding generator from dropping it. The class is completely absent from api.xml (dropped before Metadata.xml transforms run), so a full class definition is added including all fields from the Java API:
  • ContentUri (static android.net.Uri field, accessed via JNI)
  • String constants: ContentType, ContentItemType, ColumnWatchNextType, ColumnLastEngagementTimeUtcMillis
  • Int constants: WatchNextTypeContinue (0), WatchNextTypeNext (1), WatchNextTypeNew (2), WatchNextTypeWatchlist (3)
• PublicAPI.Unshipped.txt updated automatically by build

Usage

var val = TvContractCompat.WatchNextPrograms.WatchNextTypeContinue;
var uri = TvContractCompat.WatchNextPrograms.ContentUri;

@copilot you should fix this via Metadata.xml instead of adding manual bindings via Additions!

@copilot you should fix this via Metadata.xml instead of adding manual bindings via Additions!

Switched to Metadata.xml approach in b9c04f8. The fix uses remove-node + add-node to re-define TvContractCompat.WatchNextPrograms with a package-private constructor and all its fields, which prevents the binding generator from dropping it. The manual Additions/TvContractCompat.WatchNextPrograms.cs file has been removed.

@copilot instead of removing and re-adding, can you just update visibility on the members you need the visibility changed? You should not need to remove/re-add, just update the values in-place, so it's more clear what you are doing.

[Copilot]

Removed the remove-node in 9818920 — it was unnecessary since the class is already absent from api.xml (the binding generator drops it before Metadata.xml transforms run). Now it's just a single add-node.

Unfortunately, an in-place visibility update isn't possible here because the entire class gets dropped from api.xml during the class-parse → api.xml conversion (classes with only static final fields and no public constructors/methods are treated as empty). So we do need the full add-node with the class definition, constructor, and fields.
