Android: attempt to write a readonly database

Question

I have one sqlite database file and I am not able to read and write on this database file. I am using this code:

fileIsExists = new File(Environment.getExternalStorageDirectory()
            + "/bbmp/bbmp2.sqlite");
    if (fileIsExists.exists()) {
db = SQLiteDatabase.openDatabase(fileIsExists.toString(), null,
                 SQLiteDatabase.OPEN_READWRITE);        
}

This throw following error:

10-01 17:09:17.343: E/Database(9216): DELETE failed setting locale

10-01 17:09:17.374: E/Database(9216): Failed to setLocale() when constructing, closing the database
