+ * Base class for delegated apps to handle callbacks related to their delegated capabilities.
+ *
+ * <p>Delegated apps are apps that receive additional capabilities from the profile owner or
+ * device owner apps. Some of these capabilities involve the framework calling into the apps.
+ * To receive these callbacks, delegated apps should subclass this class and override the
+ * appropriate methods here. The subclassed receiver needs to be published in the app's
+ * manifest, with appropriate intent filters to mark which callbacks the receiver is interested
+ * in. An app can have multiple receivers as long as they listen for disjoint set of callbacks.
+ * For the manifest definitions, it must be protected by the
+ * {@link android.Manifest.permission#BIND_DEVICE_ADMIN} permission to ensure only
+ * the system can trigger these callbacks.
+ *
+ * <p>The callback methods happen on the main thread of the process.  Thus long running
+ * operations must be done on another thread.  Note that because a receiver
+ * is done once returning from its onReceive function, such long-running operations
+ * should probably be done in a {@link Service}.
