Hi,
I am interested in this project. I am an android application developer. I have previous experience in making custom views and custom overlays for the camera. Would you like to see a prototype activity which will open the camera but will blur the whole screen ? If you like my prototype then you can award me the project and I will complete the rest of the features. Please let me know what you think.
Also, please try to increase the upper limit of the bid range to at least € 60, as it does not make sense to invest any effort for anything less. The task may seem simple, but is worth € 60 at least.
Regards,
