Public methods

bindSlice

public abstract Slice bindSlice (Intent intent)

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

Parameters
intent	Intent: The intent associated with a slice.

Returns
Slice	The Slice provided by the app or null if none is given.

• Slice
• SliceProvider.onMapIntentToUri(Intent)
• Intent

bindSlice

public abstract Slice bindSlice (Uri uri)

Turns a slice Uri into slice content.

Parameters
uri	Uri: The URI to a slice provider

Returns
Slice	The Slice provided by the app or null if none is given.

See also:

• Slice

getInstance

public static SliceViewManager getInstance (Context context)

Get a SliceViewManager.

Parameters
context	Context

Returns
SliceViewManager

getSliceDescendants

public abstract Collection<Uri> getSliceDescendants (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.

Parameters
uri	Uri: The uri to look for descendants under.

Returns
Collection<Uri>	All slices within the space.

See also:

• SliceProvider.onGetSliceDescendants(Uri)

mapIntentToUri

public abstract Uri mapIntentToUri (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 ContentResolver.getType(Uri) is SliceProvider.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 SliceManager.SLICE_METADATA_KEY, then the Uri specified there will be returned.
3. Lastly, if the intent with SliceManager.CATEGORY_SLICE added resolves to a provider, then the provider will be asked to SliceProvider.onMapIntentToUri(Intent) and that result will be returned.
4. If no slice is found, then null is returned.

Parameters
intent	Intent: The intent associated with a slice.

Returns
Uri	The Slice Uri provided by the app or null if none exists.

• SliceProvider.onMapIntentToUri(Intent)

pinSlice

public abstract void pinSlice (Uri uri)

Ensures that a slice is in a pinned state. <
