About me

I am Arunkrishna v j . A Freelance android developer and blogger. When i first started developing android application i came across lot of issues . Many Blogs helped me  a lot in fixing those issues. Then i realized that there are many out there like me  who face same issues. So i decided to start a blog about things i learned in   android application development. My blog contains sample android application about different android features . I believe this small sample applications will help others to build there own bigger apps. 

 "Everyone should know what i know..  Knowledge increases by sharing not by saving..  "
