Public Methods

public static void cancelThumbnailRequest (ContentResolver cr, long origId)

Since: 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
origId original image id

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

Since: 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
origId original image id
groupId the same groupId used in getThumbnail.

public static Uri getContentUri (String volumeName)

Since: API Level 1

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

Parameters
volumeName the name of the volume to get the URI for
Returns
  • 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)

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

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

Since: API Level 5

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 used to dispatch queries to MediaProvider.
origId Original image id associated with thumbnail of interest.
kind The type of thumbnail to fetch. Should be either MINI_KIND or MICRO_KIND.
options this is only used for MINI_KIND when decoding the Bitmap
Returns
  • A Bitmap instance. It could be null if the original image associated with origId doesn't exist or memory is not enough.
