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 static Asset
createFromUri (Uri uri)
public boolean equals (Object o)
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.
public void writeToParcel (Parcel dest, int
flags)

Key actions include creating assets from byte arrays (`createFromBytes`), file descriptors (`createFromFd`), existing asset digests (`createFromRef`), or content URIs (`createFromUri`). Assets can be identified by their digest (`getDigest`), accessed via file descriptor (`getFd`), or URI (`getUri`). The class also provides methods for equality checks (`equals`), hashing (`hashCode`), and parceling (`writeToParcel`).\n"],null,[]]
