Thanks a lot for your reply!! I tried to launch the same application on a not-rooted device, and it gave me, unfortunately, the same result. I have also a question about CSipSimple. I've seen that that fork required to use a java support, maybe in order to avoid the problems with Android permissions', manifest files and so on. Anyway I am still perplexed, because NDK has the audio support through OpenSLES, and it gives also the support to sockets: so I initially thought that, working on C language, I should operate on Kernel level bypassing all the "Android Security Level". Next, I've read this article on source.android: http://source.android.com/tech/security/#android-platform-security-architecture I'm not misunderstanding, all the applications are run inside a "Application Sandbox", that it works in Kernel Mode. So, any attempt to run a "particular application" with audio, sockets ecc. is vain. Is there any way to bypass this "application sandbox"? Must I really use .apks in order to use Manifest permissions? Thanks again.
