我遵循了 PJSIP教程，并成功构建了 apjsua示例应用程序。

当我尝试通过 +a 添加帐户时，它会询问我 Sip Url、注册商的 Url、Auth Realm、用户名、密码

我进入了

  • 小口网址：sip:140@122.252.232.5
  • 注册商：sip:122.252.232.5
  • 授权领域：*
  • 用户名：1​​40
  • 密码：示例

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))

有谁知道我哪里错了？？？

或者有没有人知道任何其他方式为 android 使用 pjsip 库？？？

You're in luck. I was sitting with this problem a few days ago and it just looked like a simple initialization error. You should really get to grips with debugging c code else you're gonna have a hard time understanding the pjsip stack. Anyway here's what you do:

Make the "setInput" method under /pjsip-apps/src/pjsua/main_android.c look like this:

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);
}

Looking at the code changes, you should be able to see that the app_var.line char variable was not being cleared properly. Now go to the /pjsip-apps/build/ folder and execute "make". Then go to the /pjsip-apps/src/apjsua/ folder and execute "make". Thereafter refresh your eclipse project and run. That should do the trick.
