public Connector()

方法详细资料

getWritableDatabase

public static android.database.sqlite.SQLiteDatabase getWritableDatabase()

Get a writable SQLiteDatabase. There're a lot of ways to operate database in android. But LitePal doesn't support using ContentProvider currently. The best way to use LitePal well is get the SQLiteDatabase instance and use the methods like SQLiteDatabase#save, SQLiteDatabase#update, SQLiteDatabase#delete, SQLiteDatabase#query in the SQLiteDatabase class to do the database operation. It will be improved in the future.
