Hi,
Nice to meet you.
I am mobile App/Game developer in China.
I have been developing many mobile apps for over 5 years.
You can check my portfolio.
As you can see, I have many experiences with JNI.
If you hire me, I will be dedicated for our project and I will guarantee the high quality and deadline.
It is language problem so I have many experience in this area but I can't show products.
If you want I can show you some source code that use JNI to call java source form C Application.
Hope to build success with you.
Thank you.
Regards.
David
