我有一个 sqlite 数据库文件，我无法在这个数据库文件上读写。我正在使用这段代码：

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

这会引发以下错误：

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

您正在尝试以写入模式打开只读数据库。您可以在此处检查以只读模式打开数据库的代码有人可以解释这一行的作用吗？
