GENERATION_ADDED
Generation number at which metadata for this media item was first inserted. This is useful for apps that are attempting to quickly identify exactly which media items have been added since a previous point in time. Generation numbers are monotonically increasing over time, and can be safely arithmetically compared.
Detecting media additions using generation numbers is more robust than using DATE_ADDED, since those values may change in unexpected ways when apps use File.setLastModified(long) or when the system clock is set incorrectly.
Note that before comparing these detailed generation values, you should first confirm that the overall version hasn't changed by checking MediaStore.getVersion(Context, String), since that indicates when a more radical change has occurred. If the overall version changes, you should assume that generation numbers have been reset and perform a full synchronization pass.

Note: the format attribute may be ignored if the top-level MIME type disagrees with the file extension. For example, it's reasonable for an image/jpeg file to declare a format of image/vnd.google.panorama360+jpg, but declaring a format of audio/ogg would be ignored.

This value should only be used for organizational purposes, and you should not attempt to construct or access a raw filesystem path using this value. If you need to open a media item, use an API like ContentResolver.openFileDescriptor(Uri, String).
When this value is set to NULL during an android.content.ContentResolver#insert operation, the newly created item will be placed in a relevant default location based on the type of media being inserted. For example, a image/jpeg item will be placed under Environment.DIRECTORY_PICTURES.
You can modify this column during an android.content.ContentResolver#update call, which will move the underlying file on disk.
In both cases above, content must be placed under a top-level directory that is relevant to the media type. For example, attempting to place a audio/mpeg file under Environment.DIRECTORY_PICTURES will be rejected.
