Week 10

This week i had complete my apps on Android. I had research and study Java language in YouTube and other blog in order to complete on application part on Android. This is not easy, but trust me, put more effort and never give up to learn and try & error in Eclipse software. Then you can create your application yourself.

Here is the program and interface for my apps.
