Today I received a mail from Google which state that your app has been removed from Google play due to copyright infringement. The person who register this copyright issue is a person who run his non registered company. I was working with him a year back. A year ago I made an app for him. The app was not complete at the time of I left the company.
Because of some salary issue I left that company and his project a year ago. After that I worked in another company, and I learned a lot from my second company. So I thought that I should make the app that I left a year ago. Then I started work on the project from scratch, Every single line of code is written by me, I spent my 4 months and many sleep less night on that project.
Now when I published my app he report the copyright issue and my app is now removed from Google play. He is saying that you steal my code and Your app do the same things which my app do.
He also steal ideas from another apps, and there are hundreds of app of apps which does the same things. If this was his app then he should publish his app in Google play a year ago, but he does not publish with in a year.
How to react in this situation ? what should I do now? The app is the source of my income and I want my app back in the market.
