Hi, For more questions about CSipSimple, join the csipsimple developer group. You should also read with care this wiki page (it contains the link to csipsimple dev group): http://code.google.com/p/csipsimple/wiki/HowToBuild To reply your first questions, Of course all source code is available. It's released under GPL license code for the top java app part. There is several ways to use the app, as a plugin of a main android app, as a library (LGPL but requires a commercial pjsip license if you plan to release your code under commercial license and doesn't cover all parts of source code), or simply fork it as a GPL application, or simply use the lower layer that is purely the pjsip portage for android. CSipSimple also provide a full a clean android api to easily create an app on the top of it. I've also released a virtual box image for new developers that are not used to develop on android and on linux (I deeply advise developers to use linux, it's ways easier to develop). The NDK is deeply advised to build pjsip for the very good reason that it's the official way to build native apps on android. (BTW, even if you want to build it by hand with gcc, you'll need gcc from the android ndk...). Don't hesitate to join the csipsimple's dev group to post any question related to CSipSimple, I'll be pleased to reply there. Also read the wiki. It's plenty of useful information. For example the how to build will gives you a good overview of what was done to port pjsip on android. For example the tool to generate jni bindings using swig is integrated to the build system and could be useful for many other projects (btw, I release this part under apache license) On 12/03/2012 12:00, pallavi mitra wrote: > Hi all, > > Thanks for providing a platform for a technical discussion > related pjsip. > Can anybody tell details about csipsimple.Is all source codes are > accessable.What environment needed to run this .apk file.Is ndk is > compulsory in order to run in Android platform? > > thanks and regards > pallabi > Manitoba,canada > Hyderabad,India > > > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org -------------- next part -------------- An HTML attachment was scrubbed...
