为android设计pjsip的apjsua示例应用程序

Question

我已经关注了PJSIP教程,并且我已经成功构建了apjsua示例应用程序.

当我尝试通过+ a添加帐户时,它会向我询问Sip Url,注册商网址,Auth Realm,用户名,密码

我进入了

• Sip Url:sip:140@122.252.232.5
• 注册员:sip:122.252.232.5
• Auth Realm:*
• 用户名:1​​40
• 密码:例子

之后它给了我以下错误

    10-17 19:57:27.165: I/apjsua(920): 19:57:27.165  sip_resolve.c  ...Failed to resolve '122.252.232.532.5'. Err=70018 (gethostbyname() has returned error (PJ_ERESOLVE))

有没有人知道我哪里出错了???

或者有没有人知道任何其他方式使用pjsip库为Android ???

你很幸运.我几天前就遇到了这个问题,它只是一个简单的初始化错误.您应该真正掌握调试c代码,否则您将很难理解pjsip堆栈.无论如何这是你做的:

使/pjsip-apps/src/pjsua/main_android.c下的"setInput"方法如下所示:

void setInput(char *s)
{
  int i = 0;

  for (i = 0; i < sizeof(app_var.line); i++)
  {
      app_var.line[i]=NULL;
  }

  /* app_var.line[0] = 0; */

  if (strlen(s) < sizeof(app_var.line))
      strncpy(app_var.line, s, strlen(s));
  pj_sem_post(app_var.input_sem);
}

查看代码更改,您应该能够看到app_var.line char变量未正确清除.现在转到/ pjsip-apps/build /文件夹并执行"make".然后转到/ pjsip-apps/src/apjsua /文件夹并执行"make".然后刷新你的eclipse项目并运行.这应该够了吧.
