An Asset
is a binary
blob shared between data items that is replicated across the wearable network on demand.
It may represent an Asset
not yet
added with the Android Wear network. A DataItemAsset
represents an Asset
after it has
been added to the network through a PutDataRequest
.

Public Methods
public static Asset
createFromBytes
(byte[]
assetData)
Creates an Asset
using
a byte array.
Creates an Asset
using
a file descriptor. The FD should be closed after being successfully sent in a DataClient.putDataItem(PutDataRequest)
request.
The Wearable API will copy the file descriptor's data in the caller's process as
soon as the corresponding PutDataRequest
is provided to the API.

public String
getDigest
()
Returns the digest associated with the Asset
data.
A digest is a content identifier used to identify the Asset
across
devices.
Returns
- the
Asset
's
digest, or null
if the digest is unset
Returns the file descriptor referencing the Asset
.
public Uri
getUri
()
Returns the uri referencing the Asset
data.

Key actions include creating assets from byte arrays (`createFromBytes`), file descriptors (`createFromFd`), existing asset digests (`createFromRef`), or content URIs (`createFromUri`).

The class also provides methods for equality checks (`equals`), hashing (`hashCode`), and parceling (`writeToParcel`).\n"],null,[]]
