Public Methods

public static void cancelThumbnailRequest (ContentResolver cr, long origId)

Added in API level 5

This method cancels the thumbnail request so clients waiting for getThumbnail will be interrupted and return immediately. Only the original process which made the getThumbnail requests can cancel their own requests.

Parameters
cr ContentResolver: ContentResolver
origId long: original video id

public static void cancelThumbnailRequest (ContentResolver cr, long origId, long groupId)

Added in API level 8

This method cancels the thumbnail request so clients waiting for getThumbnail will be interrupted and return immediately. Only the original process which made the getThumbnail requests can cancel their own requests.

Parameters
cr ContentResolver: ContentResolver
origId long: original video id
groupId long: the same groupId used in getThumbnail.

public static Uri getContentUri (String volumeName)

Added in API level 5

Get the content:// style URI for the image media table on the given volume.

Parameters
volumeName String: the name of the volume to get the URI for
Returns
Uri the URI to the image media table on the given volume

public static Bitmap getThumbnail (ContentResolver cr, long origId, long groupId, int kind, BitmapFactory.Options options)

Added in API level 8

This method checks if the thumbnails of the specified image (origId) has been created. It will be blocked until the thumbnails are generated.

Parameters
cr ContentResolver: ContentResolver used to dispatch queries to MediaProvider.
origId long: Original image id associated with thumbnail of interest.
groupId long: the id of group to which this request belongs
kind int: The type of thumbnail to fetch. Should be either MINI_KIND or MICRO_KIND
options BitmapFactory.Options: this is only used for MINI_KIND when decoding the Bitmap
Returns
Bitmap A Bitmap instance. It could be null if the original image associated with origId doesn't exist or memory is not enough.
