DrmUtils.ExtendedMetadataParser


public static class DrmUtils.ExtendedMetadataParser
extends Object

java.lang.Object
   ↳ android.drm.DrmUtils.ExtendedMetadataParser


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);
}
