    <p>When using the SIP API, how can I answer a call I'm receiving. Im using the incomingcallreceiver class from sipdemo for testing and I added a pickup button in the WalkieTalkieActivity class that should be enabled when a call comes in but I cant figure out how to pickup an inbound call. Any help or examples would be appreciated. </p> <p>To be more specific, here is the sample code from IncomingCallReceiver class:</p> <pre><code>public class IncomingCallReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { SipAudioCall incomingCall = null; try { SipAudioCall.Listener listener = new SipAudioCall.Listener() { @Override public void onRinging(SipAudioCall call, SipProfile caller) { try { call.answerCall(30); } catch (Exception e) { e.printStackTrace(); }}}; WalkieTalkieActivity wtActivity = (WalkieTalkieActivity) context; incomingCall = wtActivity.manager.takeAudioCall(intent, listener); incomingCall.answerCall(30); incomingCall.startAudio(); incomingCall.setSpeakerMode(true); if(incomingCall.isMuted()) { incomingCall.toggleMute(); } wtActivity.call = incomingCall; wtActivity.updateStatus(incomingCall); } catch (Exception e) { if (incomingCall != null) { incomingCall.close(); }}}} </code></pre> <p>The WalkieTalkieActivity class uses the following for receiving a call: within onCreate</p> <pre><code>IntentFilter filter = new IntentFilter(); filter.addAction("android.SipDemo.INCOMING_CALL"); callReceiver = new IncomingCallReceiver(); this.registerReceiver(callReceiver, filter); </code></pre> <p>and where the profile is created</p> <pre><code>Intent i = new Intent(); i.setAction("android.SipDemo.INCOMING_CALL"); PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, Intent.FILL_IN_DATA); manager.open(me, pi, null); </code></pre> <p>According to the developer SIP <a href="http://developer.android.com/guide/topics/network/sip.html" rel="nofollow">guide</a>:</p> <p>When the SIP service receives a new call, it sends out an intent with the action string provided by the application. In SipDemo, this action string is android.SipDemo.INCOMING_CALL. </p> <p>This code excerpt from SipDemo shows how the SipProfile object gets created with a pending intent based on the action string android.SipDemo.INCOMING_CALL. The PendingIntent object will perform a broadcast when the SipProfile receives a call: (This referred to the code above where the profile is created) The guide then goes on to say: The broadcast will be intercepted by the intent filter, which will then fire the receiver (IncomingCallReceiver). You can specify an intent filter in your application's manifest file, or do it in code as in the SipDemo sample application's onCreate() method of the application's Activity:</p> <p>Im looking to add a pickup button to the WalkieTalkieActivity class that is enabled onRinging and will answer an incoming call when clicked.</p> <p>I have been successful with handling all other general calling issues such as hold, mute, speaker, making calls, and ending calls but I cannot figure this out.</p> <p>Edit - Could this work?:</p> <pre><code>public class IncomingCallReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { SipAudioCall incomingCall = null; try { SipAudioCall.Listener listener = new SipAudioCall.Listener() { @Override public void onRinging(SipAudioCall call, SipProfile caller) { try { call.answerCall(30); } catch (Exception e) { e.printStackTrace(); }}}; WalkieTalkieActivity wtActivity = (WalkieTalkieActivity) context; wtActivity.inbound = incomingCall; wtActivity.updateStatus(incomingCall); } catch (Exception e) { if (incomingCall != null) { incomingCall.close(); }}}} </code></pre> <p>and then set up a new SipAudioCall within the walkietalkieactivity Class and a listener for onRinging with the onclicklistener inside of it followed by normal call handling like:</p> <pre><code>inbound.answerCall(30); inbound.startAudio(); inbound.setSpeakerMode(true); if(inbound.isMuted()) { inbound.toggleMute(); } </code></pre> <p>--Thanks Daniel</p>

    2. COThe ReceiveIncomingCall class includes answerCall [link](http://developer.android.com/resources/samples/SipDemo/src/com/example/android/sip/IncomingCallReceiver.html) but I dont understand how it is called or how to call it from an onclick listener within WalkieTalkieActivity class.

    3. COAfter reading more about intents,filters,and broadcast, from what I can tell, incoming calls are received automatically. My friend also pointed out that the sip demo is a walkie talkie or touch to talk type app where I am working on a sip soft phone and a walkie talkie app would automatically answer calls. I just need to figure out how to handle the incoming call differently.

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
