我正在用 sense 2.1 在根植于 Android 2.3.3 htc 令人难以置信的 S 上编写 MMS/SMS 应用程序。现在，在尝试接收某个 SMS/MMS 的联系人列表时，我在查询中得到了一个 FC。

这是一些代码：

Uri uri = Uri.parse("content://mms-sms/conversations/"+String.valueOf(thread_id));
ContentResolver cr = context.getContentResolver();
Cursor c= cr.query(uri,null,null,null,null);    //crashing here

好的，修好了。诀窍是在投影中输入实际的列名。似乎这个错误毕竟是android的。

根据this other answer第二个参数不应该为空（尽管文档说这是一个有效值），试试

final String[] projection = new String[]{"*"};
Cursor query = contentResolver.query(uri, projection, null, null, null);
