I want to create an app as follows:-
1. Camera icon on the main screen of my android phone.
2. When I open the app camera will start. Then I will show a page on that camera and there will be bar code on it. Camera will read the bar code and instead of displaying the page it will start running the video.
Now it can start any one of the 50 or 100 or any video of my choice. I will at the backend somehow approve one of the videos and it will play that particular video.
