Method Detail

• getWritableDatabase

  SQLiteDatabase getWritableDatabase()

  Creates and/or opens a database that will be used for reading and writing.

  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.

  Throws:

  SQLiteException - If the database cannot be opened for writing.

• getReadableDatabase

  SQLiteDatabase getReadableDatabase()

  Creates and/or opens a database. This will be the same object returned by getWritableDatabase() unless some problem, such as a full disk, requires the database to be opened read-only. In that case, a read-only database object will be returned. If the problem is fixed, a future call to getWritableDatabase() may succeed, in which case the read-only database object will be closed and the read/write object will be returned in the future.

  Once opened successfully, the database is cached, so you can call this method every time you need to read from the database.

  Returns:

  A database object valid until getWritableDatabase() is called.

  Throws:

  SQLiteException - If the database cannot be opened.
