public abstract @Nullable Slice bindSlice(@NonNull Intent intent)

Turns a slice intent into slice content. Is a shortcut to perform the action of both mapIntentToUri and bindSlice at once.

public abstract @Nullable Slice bindSlice(@NonNull Uri uri)

Turns a slice Uri into slice content.

public static @NonNull SliceViewManager getInstance(@NonNull Context context)

Get a SliceViewManager.

@WorkerThread
public abstract @NonNull Collection<Uri> getSliceDescendants(@NonNull Uri uri)

Obtains a list of slices that are descendants of the specified Uri.

Not all slice providers will implement this functionality, in which case, an empty collection will be returned.

public abstract @Nullable Uri mapIntentToUri(@NonNull Intent intent)

Turns a slice intent into a slice uri. Expects an explicit intent.

This goes through a several stage resolution process to determine if any slice can represent this intent.

1. If the intent contains data that getType is SLICE_TYPE then the data will be returned.
2. If the intent explicitly points at an activity, and that activity has meta-data for key SLICE_METADATA_KEY, then the Uri specified there will be returned.
3. Lastly, if the intent with CATEGORY_SLICE added resolves to a provider, then the provider will be asked to onMapIntentToUri and that result will be returned.
4. If no slice is found, then null is returned.

public abstract void pinSlice(@NonNull Uri uri)

Ensures that a slice is in a pinned state.

Pinned state is not persisted across reboots, so apps are expected to re-pin any slices they still care about after a reboot.

public abstract void registerSliceCallback(
 @NonNull Uri uri,
 @NonNull SliceViewManager.SliceCallback callback
)

Adds a callback to a specific slice uri.

This is a convenience method that performs a few slice actions at once. It will put the slice in a pinned state since there is a callback attached. It will also listen for content changes, when a content change is observed, the android system will bind the new slice and provide it to all registered SliceCallbacks.

This will not trigger a bindSlice immediately, it will only perform a bind and pass it to the callback after a change occurs. To avoid race conditions and missing data, callers should call bindSlice immediately after calling registerSliceCallback so that it has the current slice.

public abstract void registerSliceCallback(
 @NonNull Uri uri,
 @NonNull Executor executor,
 @NonNull SliceViewManager.SliceCallback callback
)

Adds a callback to a specific slice uri.

This is a convenience that performs a few slice actions at once. It will put the slice in a pinned state since there is a callback attached. It will also listen for content changes, when a content change observes, the android system will bind the new slice and provide it to all registered SliceCallbacks.

public abstract void unpinSlice(@NonNull Uri uri)

Remove a pin for a slice.

If the slice has no other pins/callbacks then the slice will be unpinned.

public abstract void unregisterSliceCallback(
 @NonNull Uri uri,
 @NonNull SliceViewManager.SliceCallback callback
)

Removes a callback for a specific slice uri.

Removes the app from the pinned state (if there are no other apps/callbacks pinning it) in addition to removing the callback.
