             android.database.sqlite.SQLiteOpenHelper databaseOpenHelper)

Create an FtsOpenHelper object

Parameters:

Method Detail

getWritableDictionaryDatabase

public android.database.sqlite.SQLiteDatabase getWritableDictionaryDatabase()

Create and/or open dictionary database that will be used for reading and writing. The first time this is called, the database will be opened and SQLiteOpenHelper.onCreate(android.database.sqlite.SQLiteDatabase), SQLiteOpenHelper.onUpgrade(android.database.sqlite.SQLiteDatabase, int, int) and/or SQLiteOpenHelper.onOpen(android.database.sqlite.SQLiteDatabase) will be called.

Once opened successfully, the database is cached, so you can call this method every time you need to write to the database. Errors such as bad permissions or a full disk may cause this method to fail, but future attempts may succeed if the problem is fixed.

Returns:

A read/write database object valid until SQLiteClosable.close() is called

Throws:

android.database.sqlite.SQLiteException - if the database cannot be opened for writing

getReadableDictionaryDatabase

public android.database.sqlite.SQLiteDatabase getReadableDictionaryDatabase()

Throws:
