I have developed applications with android SDK. However I want to know what is NDK and how to use it?

Question

I was trying to develop an NDK application with gradle and that caused some errors. So, I changed to gradle-experimental. Now it works, but other functionalities are not working now. What should I do?

Answer 1

Android NDK is the package that allows the developers to develop part of application to be in either C or C++.
.
Why do we need c/c++ for?
To access core dalvik features, make some intensive calculations, etc.,
.
Things to do even when you are in native development:
Let's just say you are developing a part of application using c or c++, it doesn't mean it will handle memory allocation and deallocation by itself. We have to take care of that properly..
.
Why not to use NDK
Well, you can't (or don't want to) develop the whole application in C or C++. Because you could possibly introduce bugs and device/platform specific features that inturn become bugs for other devices or OSs. And since you have access to dalvik features you should probably be more careful working with NDK.
.
Hope this helps.
