I have developed windows phone 8.1 that is not working with other platforms.
Is there any way to develop windows phone app that works with all windows phone platforms link 7,8 and 8.1?

Your app written for WP8.1 won't work on WP7.x - it's different API.
If you want to write an app for all platforms (WP7.x and WP8.x) then you will have to do it with the oldest API - WP7.x. Apps written this way should run on WP8.x devices - some more reference in this question.
Every API has its own Minimum supported phone - you will find it at the end of every class/method description at MSDN.
