android.database

---

Contains classes to explore data returned through a content provider.

If you need to manage data in a private database, use the android.database.sqlite classes. These classes are used to manage the Cursor object returned from a content provider query. Databases are usually created and opened with openOrCreateDatabase(String, int, CursorFactory) To make requests through content providers, you can use the content.ContentResolver class.

All databases are stored on the device in /data/data/<package_name>/databases

Interfaces

CrossProcessCursor	A cross process cursor is an extension of a Cursor that also supports usage from remote processes.
Cursor	This interface provides random read-write access to the result set returned by a database query.
DatabaseErrorHandler	An interface to let apps define an action to take when database corruption is detected.

Classes

AbstractCursor	This is an abstract cursor class that handles a lot of the common code that all cursors need to deal with and is provided for convenience reasons.
AbstractCursor.SelfContentObserver	Cursors use this class to track changes others make to their URI.
AbstractWindowedCursor	A base class for Cursors that store their data in CursorWindows.
CharArrayBuffer	This is used for Cursor#copyStringToBuffer
ContentObservable	A specialization of Observable for ContentObserver that provides methods for sending notifications to a list of ContentObserver objects.
ContentObserver	Receives call backs for changes to content.
CrossProcessCursorWrapper	Cursor wrapper that implements CrossProcessCursor.
CursorJoiner	Does a join on two cursors using the specified columns.
CursorWindow	A buffer containing multiple cursor rows.
CursorWrapper	Wrapper class for Cursor that delegates all calls to the actual cursor object.
DatabaseUtils	Static utility methods for dealing with databases and Cursors.
DatabaseUtils.InsertHelper	This class was deprecated in API level 17. Use SQLiteStatement instead.
DataSetObservable	A specialization of Observable for DataSetObserver that provides methods for sending notifications to a list of DataSetObserver objects.
DataSetObserver	Receives call backs when a data set has been changed, or made invalid.
DefaultDatabaseErrorHandler	Default class used to define the action to take when database corruption is reported by sqlite.
MatrixCursor	A mutable cursor implementation backed by an array of Objects.
MatrixCursor.RowBuilder	Builds a row of values using either of these approaches: Values can be added with explicit column ordering using add(java.lang.Object), which starts from the left-most column and adds one column value at a time.
MergeCursor	A convenience class that lets you present an array of Cursors as a single linear Cursor.
Observable<T>	Provides methods for registering or unregistering arbitrary observers in an ArrayList.

Enums

CursorJoiner.Result

The result of a call to next().

Exceptions

CursorIndexOutOfBoundsException	An exception indicating that a cursor is out of bounds.
CursorWindowAllocationException	This exception is thrown when a CursorWindow couldn't be allocated, most probably due to memory not being available.
SQLException	An exception that indicates there was an error with SQL parsing or execution.
StaleDataException	This exception is thrown when a Cursor contains stale data and must be requeried before being used again.
