使用 Android SIP 堆棧注冊 SIP 配置文件

Question

我一直在開發一個應用程序，該應用程序使用戶能夠使用受 SIPDemo 啟發的 SIP 撥打和接聽電話，在我從手機上卸載該應用程序之前，它運行良好，它進行了注冊，顯示消息“就緒”和然后着手進行通話處理。 現在它沒有進入 Sipregistrationlistener 並顯示錯誤“嘗試關閉管理器 1 SipException 時出錯：無法創建 SipSession；網絡不可用？”。

據我了解，我懷疑問題是由於以前的 SIP 帳戶仍然鏈接，因此在應用程序中自動打開，不允許任何注冊，如這篇文章的解決方案中所述“ Android Native SIP Stack not registering客戶端”，但我不知道如何處理這個，在onDestroy上引入closelocalprofile function，onPause沒有效果。 此外，直到最近它確實顯示消息“SipManager 已准備好調用”並且它已打開，但現在盡管沒有更改代碼中的任何內容，但現在它沒有顯示，因此問題可能不一定是這個。

在打印方面，顯示了以下消息： - 不顯示與狀態相關的消息； - 日志顯示“創建管理器”和“構建新配置文件”；

此外，我已經擁有支持 SIP 通信的權限和清單編碼。

我現在知道這個堆棧不是最好的，但我不想放棄這個項目，所以任何幫助或提示將不勝感激。 在最后一種情況下，如果沒有找到解決方案/進展，如果你們中的任何人也可以向類似的替代堆棧提供建議，那也將不勝感激。

這是代碼：

public SipManager sipManager = null;//SIPMANAGER
public SipProfile sipProfile = null;//SIPPROFILE
public SipAudioCall call = null;//SIPAUDIOCALL
public IncomingCallReceiver callReceiver;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    Permissions();
    Supported();

    initManager();

    MakeCallButton.setOnClickListener(new View.OnClickListener() /onclick event
    {
        @Override
        public void onClick(View view)
        {
           initCall();
        }
    });
    EndCallButton.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view) {
            try
            {
                call.endCall();
            }
            catch (SipException e)
            {
                status("Error when trying to end call. " + e);
            }
        }
    });
}

public void initManager()//SIPMANAGER

更新

通過在重新安裝應用程序后重新啟動設備並將代碼從 Android Studio 重新發送到手機的組合，設法繞過這些先前的錯誤。 如上所述，我對錯誤來源的懷疑是由於此堆棧存在的錯誤，但它現在可以正常工作並且我對成品感到滿意。

盡管在這里沒有得到任何回應，但我希望這個帖子可以對某人有所幫助。
