Android video calls using android's sip

问题:

I want to develop a program for a video calls in android. I thought of using the built in sip that introduced in android 2.3.3. But how can I initiate the video calls? I see that it is not supported.

回答1:

I believe the generic Android SIP stack supports video.

If you want to create generic SIP connections (such as for video calls or other), you can create a SIP connection from the SipManager, using open(). If you only want to create audio SIP calls, though, you should use the SipAudioCall class, as described above.

If you don't mind using external SIP stacks, check out this:

which uses Jain-SIP.

EDIT: As of late, this project seems to be the leader in the native Android SIP space:
