DrmUtils.ExtendedMetadataParser
extends Object
Utility that parses extended metadata embedded in DRM constraint information.
Usage example:
byte[] extendedMetadata
=
constraints.getAsByteArray(DrmStore.ConstraintsColumns.EXTENDED_METADATA);
ExtendedMetadataParser parser = getExtendedMetadataParser(extendedMetadata);
Iterator keyIterator = parser.keyIterator();
while (keyIterator.hasNext()) {
String extendedMetadataKey = keyIterator.next();
String extendedMetadataValue =
parser.get(extendedMetadataKey);
}
