In that specific example, and in many others, the framework is calling down into native code through system wrappers (from harmony, is it still called that...?) To handle these cases, when you get down to a baseline set of system calls (i.e., the traditional unix ones..), the code is in classes like OSNetworkSystem.java ..., for example (the first google result..): http://code.google.com/p/sipdroid/source/browse/trunk/src/org/sipdroid/net/impl/OSNetworkSystem.java?r=156 There's a similar implementation for the filesystem, etc... kris -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
