Constructor Detail

Method Detail

onCreate

public final void onCreate(android.database.sqlite.SQLiteDatabase db)

Satisfies the SQLiteOpenHelper.onCreate(SQLiteDatabase) interface method.

Specified by:

onCreate in class android.database.sqlite.SQLiteOpenHelper

onUpgrade

public final void onUpgrade(android.database.sqlite.SQLiteDatabase db,
             int oldVersion,
             int newVersion)

Satisfies the SQLiteOpenHelper.onUpgrade(SQLiteDatabase, int, int) interface method.

Specified by:

onUpgrade in class android.database.sqlite.SQLiteOpenHelper

onDowngrade

public void onDowngrade(android.database.sqlite.SQLiteDatabase db,
               int oldVersion,
               int newVersion)

Called when the database needs to be downgraded. This is strictly similar to onUpgrade(android.database.sqlite.SQLiteDatabase, int, int) method, but is called whenever current version is newer than requested one. Supported to allow database version change during testing. A script is required to support the downgrade, so still under customer control as intended by design.

db - The database.

oldVersion - The old database version.

newVersion - The new database version.
