I am developing an Android App. I was able test it on my device successfully. So I pushed the released version on Google Play store. Now I uninstalled the debug build from my device and tried to download it from the Play Store. But when I click on install button, I am getting this error.
you cannot install this app because another user has already installed an incompatible version on this device...
I am only using Google Play services. Not using any storage or anything that might be different for different users and Android L. What changes should I make in my app source to resolve this?
