Android：尝试编写只读数据库

Question

我有一个sqlite数据库文件，我无法读取和写入此数据库文件。 我正在使用此代码：

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

抛出以下错误：

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
