Most NDK techniques requires the use of command-line and some sort of Linux shell and that one thing that I really dreaded, but if you are brave enough here’s a link to the documentation. Porting from a large C/C++ code-base, for code reuse, to save time and efforts.

Execution speed (Java is almost always slower than C/C++ and it is easier to optimize C/C++ code than Java code).Ģ. Why use JNI? I can think of two obvious answers:ġ. You still need to use Java to call the Native Interfaces, but you can code most of you app in C/C++.
