Delphi XE5 App does not work with Android Lollipop

Last year I developed a prototype App using Delphi XE5 and deploying to my Nexus 4. It all worked OK and I was fairly happy with what I had. Last month I updated my Nexus phone to Android Lollipop, the other day I tried to open the App and nothing happened it just did not work anymore. I was a little disappointed and a similar App I had developed using Xamarin still worked fine. I am now not sure how feasible it is using Delphi to develop Android Apps.
