我正在使用Twilio android SDK，当我点击“挂断”按钮时总是出现错误？拨号后无法断开呼叫？

我已成功集成了适用于android的Twilio SDK，但当我尝试使用它进行呼叫时，它未连接并在logcat中显示错误消息，我收到以下错误：

1) Failed to hangup call due to error code: 70015, message: pjsua_call_hangup(): Object already exists (PJ_EEXISTS) 

2) Connection disconnected with error code 31000 and message Generic error 

this both errors occurs when i am calling disconnect method if i comment this method then my calling is working fine and i make call but if i call this method phone.disconnect(), i am getting error shown as above. 

This is my methods which i am using to make calls and to disconnect the calls. 

//////打电话

public void connect(String phoneNumber) { 
Map parameters = new HashMap(); 
parameters.put("PhoneNumber", phoneNumber); 
connection = device.connect(parameters, null /* ConnectionListener */); 
if (connection == null) 
Log.w(TAG, "Failed to create new connection"); 
} 

//断开电话

public void disconnect() { 
if (connection != null) { 
connection.disconnect(); 
connection = null; // will null out in onDisconnected() 
if (basicConnectionListener != null) 
basicConnectionListener.onConnectionDisconnecting(); 
} 
} 

在我的OnClick活动中：

public void onClick(View view) { 
if (view.getId() == R.id.dialButton) 
Toast.makeText(getApplicationContext(), "Dialing...", Toast.LENGTH_LONG).show(); 
phone.connect("PHONE NUMBER"); 
if (view.getId() == R.id.hangupButton) 
Toast.makeText(getApplicationContext(), "Call Disconnected...", Toast.LENGTH_LONG).show(); 
phone.disconnect(); 

Please suggest me and help me because i tried all possible thing for hangout but still not able to solve it.Thanks in advance. ![enter image description here][1]

嗨，我也面临同样的问题。如果您得到了解决方案，请将其发布在此处有时我的应用程序会出现在

connection=device.connect（参数，null/*ConnectionListener*/）上

你能帮我一下吗？@AnshulTyagi您好，有时候会发生这种情况，因为设备无法创建新连接。所以它会崩溃。请尝试使用我创建的上述类，它在所有情况下都非常适合我。谢谢。我已经测试了15次，它不再崩溃了。我刚刚在try-catch块

device=Twilio.createDevice（capabilityToken，null/*DeviceListener*/）中添加了这一行@AnshulTyagi很高兴听到我的答案对你有用。如果你觉得我的答案有用，你可以接受。谢谢：）@Nidhi嘿，这个代码对我来说很有魅力，我想你在Twillio帐户上的代币有问题。请检查你的代币和帐户设置，这可能对你有帮助。
  private MonkeyPhone phone;
  //On create
  phone = new MonkeyPhone(getApplicationContext());

  //On Call Button Click

  @Override
    public void onClick(View view) {
        if (view.getId() == R.id.btnCallHere) {

            phone.connect(newContact);  

        } else if (view.getId() == R.id.btnDisconnectHere) {

            phone.disconnect();
