does android natively support RTP and/or SCTP?

I am developing a walkie-talkie application fo开发者_如何学运维r Android, and would like to know whether RTP and/or SCTP is natively supported in the latest version of android SDK.

From whatever I have dug-up so far, the answer is no.

It seems that support for SCTP is coming in JDK 7. But then, I am not sure how this will work with my android developemnt.

Could you please shed some light over this?

Thanks,

No it doesn't support RTP as standard you will have to use a JAVA RTP library.

Android uses a subset of the Java libraries so is not full Java with this in mind it is unlikely that the SCTP support will be implemented natively in Android
