试图异常时，调用（SIP） [英] Exception when trying to call(SIP)

问题描述

我的深化发展SIP应用程序，当我想打电话给某人（与配置服务器的标识符），我有一个NullPointerException异常=>错误试图关闭管理器时。 这里是code：

 公共无效initiateCall（）{

        updateStatus（sipAddress）;

        尝试 {
            SipAudioCall.Listener监听器=新SipAudioCall.Listener（）{

                @覆盖
                公共无效onCallEstablished（SipAudioCall调用）{
                    call.startAudio（）;
                    call.setSpeakerMode（真正的）;
                    call.toggleMute（）;
                    updateStatus（电话）;
                }

                @覆盖
                公共无效onCallEnded（SipAudioCall调用）{
                    updateStatus（准备好了。）;
                }
            };

            调用= manager.makeAudioCall（me.getUriString（），sipAddress，监听器，30）;

        }
        赶上（例外五）{
            Log.i（试图关闭经理时出现错误。WalkieTalkieActivity / InitiateCall，E）;
            如果（我！= NULL）{
                尝试 {
                    manager.close（me.getUriString（））;
                }赶上（例外EE）{
                    Log.i（WalkieTalkieActivity / InitiateCall
                            错误当试图关闭经理，EE）;
                    ee.printStackTrace（）;
                }
            }
            如果（呼！= NULL）{
                call.close（）;
            }
        }
    }
 

感谢您的帮助。

解决方案

在VOIP / SIP libary是默认不支持的Andr​​oid模拟器

。问题是，
经理== NULL - 这就是为什么你所得到的NullPointerException异常

幸运的是，有一个工作一个圆。下载此链接并将其复制到 ... \。安卓\ AVD \ .avd 文件夹。

启动模拟器以及

 布尔voipSupported = SipManager.isVoipSupported（本）;
 布尔apiSupported = SipManager.isApiSupported（本）;
 

现在应该返回true。

I'm developping a SIP application, and when i want to call someone(with its identifier configured in the server) i have a NullPointerException => "Error when trying to close manager." Here is the code:

public void initiateCall() {

        updateStatus(sipAddress);

        try {
            SipAudioCall.Listener listener = new SipAudioCall.Listener() {

                @Override
                public void onCallEstablished(SipAudioCall call) {
                    call.startAudio();
                    call.setSpeakerMode(true);
                    call.toggleMute();
                    updateStatus(call);
                }

                @Override
                public void onCallEnded(SipAudioCall call) {
                    updateStatus("Ready.");
                }
            };

            call = manager.makeAudioCall(me.getUriString(), sipAddress, listener, 30);

        }
        catch (Exception e) {
            Log.i("WalkieTalkieActivity/InitiateCall", "Error when trying to close manager.", e);
            if (me != null) {
                try {
                    manager.close(me.getUriString());
                } catch (Exception ee) {
                    Log.i("WalkieTalkieActivity/InitiateCall",
                            "Error when trying to close manager.", ee);
                    ee.printStackTrace();
                }
            }
            if (call != null) {
                call.close();
            }
        }
    }

Thank you for your help.

解决方案

The VOIP/SIP libary is not supported by default on Android emulator. The problem is that the
manager == null - thats why you are getting the NullPointerException.

Luckily, there is a work-a-round. Download this link and copy it into ...\.android\avd\.avd folder.

Start your emulator and

 Boolean voipSupported = SipManager.isVoipSupported(this);
 Boolean apiSupported = SipManager.isApiSupported(this);

should now return true.
