Access android context in ndk application
Is there any way in which I can pass/get an object of android context in my ndk appliation. I want to use SharedPreferences in my ndk application via jni interface. To get an instance of SharedPreferences object, I need to call getSharedPreferences() on Context object. But I do not have access to the context object. OR How can I read and write an xml file from NDK ? Any pointers will be appreciate

Android Developers Blog: Avoiding memory leaks
Android applications are, at least on the T-Mobile G1, limited to 16 MB of heap. It's both a lot of memory for a phone and yet very little for what some developers want to achieve.

The more applications Android can keep in memory, the faster it will b
