我正在一个已root的Android 2.3.3 htc incredible S上编写一款MMS/SMS应用程序,使用了sense 2.1。 现在,在尝试接收某个联系人SMS/MMS列表时,查询会导致FC。
以下是相关代码:
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
