ComponentCallbacks2 Extended ComponentCallbacks interface with a new callback for finer-grained memory management. 
ContentProvider.PipeDataWriter<T> Interface to write a stream of data to a pipe. 
DialogInterface.OnCancelListener Interface used to allow the creator of a dialog to run some code when the dialog is canceled. 
DialogInterface.OnClickListener Interface used to allow the creator of a dialog to run some code when an item on the dialog is clicked..

SharedPreferences.OnSharedPreferenceChangeListener Interface definition for a callback to be invoked when a shared preference is changed. 


AbstractThreadedSyncAdapter An abstract implementation of a SyncAdapter that spawns a thread to invoke a sync operation.

IntentFilter.AuthorityEntry This is an entry for a single authority in the Iterator returned by authoritiesIterator()
IntentSender A description of an Intent and target action to perform with it. 
Loader<D> A class that performs asynchronous loading of data. 
Loader.ForceLoadContentObserver An implementation of a ContentObserver that takes care of connecting it to the Loader to have the loader re-load its data when the observer is told it has changed. 
MutableContextWrapper Special version of ContextWrapper that allows the base context to be modified after it is initially set.

SyncStats Used to record various statistics about the result of a sync operation. 
UriMatcher Utility class to aid in matching URIs in content providers. 
UriPermission Description of a single Uri permission grant. 


ActivityNotFoundException This exception is thrown when a call to startActivity(Intent) or one of its variants fails because an Activity can not be found to execute the given Intent.
