尝试呼叫时出现异常(SIP) [英] Exception when trying to call(SIP)
问题描述
我正在开发一个SIP应用程序,当我想呼叫某人(在服务器中配置了其标识符)时,我有一个NullPointerException =>尝试关闭管理器时出错。
这里是代码:
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();
}
}
}
感谢您的帮助。
推荐答案
默认情况下,Android模拟器不支持VOIP / SIP libary。问题是,
manager == null
- 这就是为什么你得到NullPointerException。
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.
幸运的是,有一个工作一轮。下载此链接并将其复制到 ... \.android\avd\\ \\.avd 文件夹。
Luckily, there is a work-a-round. Download this link and copy it into ...\.android\avd\.avd folder.
启动你的模拟器和
Boolean voipSupported = SipManager.isVoipSupported(this);
Boolean apiSupported = SipManager.isApiSupported(this);
现在应该返回true。
should now return true.
