我正在尝试使用代码启动一个新活动:

Intent i = new Intent(this, TempLobbyActivity.class);
startActivity(i);
finish();

当我启动此代码时,我在执行Intent构造函数时遇到以下异常.

每当我的程序到达一个write()函数时，我都会收到此错误。该程序将再次继续，但将在下一次write()调用时停止。当我在 gdb 之外运行该程序时，它运行正常。

Program received signal SIGPIPE, Broken pipe.
0x00007ffff794b340 in __write_nocancel () at ../sysdeps/unix/syscall-template.S:81
81      ../sysdeps/unix/syscall-template.S: No such file or directory.

有人告诉我，当从远程端关闭套接字时会发生这种情况，但这是如何发生的。

注意：服务器和客户端都在同一台计算机上运行，​​并且服务器是为我预先构建的，因此我无权访问它的代码。

SELECT * FROM iveflownthat.messages WHERE from=1 OR to=1

它一直给我错误.我检查以确保字段,表和数据库名称正确.
