Android NDK examples

You can build android apps in C++ using Android NDK, but you will not be able to exploit vast android libraries that were developed and to be used through JAVA.Development in NDK is also time consuming and C++ code also needs to be compiled in each platform for distribution as it is not platform independent.

You cannot directly run C++ applications in Android . Android can run only applications written using the Android SDK, but yes you can re-use your native(C/C++) libraries for Android.

C and C++ allow developers direct access to low-level features of the underlying operating system , giving skilled programmers the opportunity to write highly optimized code. Since Java runs within a virtual machine, access to such low-level functions is abstracted.
