Asset

    • Asset represents a binary blob shared between data items that is replicated across the wearable network on demand.

    • An Asset can be created from a byte array, file descriptor, existing Asset's digest, or a content URI.

    • The digest of an Asset is a content identifier used to identify the Asset across devices.

    • An Asset can be referenced by a file descriptor or a content URI.

    implements Parcelable Parcelable

    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 .

    Fields

    public static final Creator < Asset > CREATOR

    Public Methods

    public static Asset createFromBytes (byte[] assetData)

    Creates an Asset using a byte array.

    public static Asset createFromFd ( ParcelFileDescriptor fd)

    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 createFromRef ( String digest)

    Create an Asset using an existing Asset 's digest.

    public static Asset createFromUri ( Uri uri)

    Creates an Asset using a content URI. The Asset will be opened using ContentResolver.openFileDescriptor(Uri, String) .

    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

    public ParcelFileDescriptor getFd ()

    Returns the file descriptor referencing the Asset .

    public Uri getUri ()

    Returns the uri referencing the Asset data.

    public int hashCode ()

    public String toString ()

    public void writeToParcel ( Parcel dest, int flags)
