Well currently I’m working on a project and came across Sliding menu,i googled but get disappointed to see that no one has given some instructions or hints on how to start making a sliding menu, Every one has given link to some Github’s projects/libraries to use, Hence I decided to do it myself and finally i have my own Sliding Menu Ready…
I have Spent two days on it
1. on making animations of sliding
2. on making it work with all screen resolutions
Its really easy and simple once you get some idea about Animations, I have read some where, its not sensible to re-invent the Wheel(people who are refering to github source code of sliding menu),but i believe that you should at least once try to make your own so you get a idea how it actually works and function 😛
So this is a picture of how my sliding menu will going to work

There you go a complete working and functional Sliding Menu, and you can customized it to meet your requirements,if any one still have some problems setting up,feel free to ask,i feel pleasure to help you out 🙂
