I am trying to develop android app in which I have an image target on which i want to play videos. After detecting image target, i want to show some clickable buttons on phone screen. When user selects a button, accordingly I want to play a video. I am havig different videos for different button click. I want to show clickable buttons on screen only after detecting image target. I went through videoplayback code and am clueless how to process. Please help me by giving some pointer to proceed.
