build me a drowsiness detection application

i need to build an android application that can detects drowsiness by opening a camera develop using tensorflow lite and android sdk . My aim is that the project will use datasets from kaggle to enhance facial expression of only yawning and eyes closing. But in most muslim countries, some people may use their hands to cover their mouth if they yawn. So i need an app do determine that too. Furthermore, i want to add haar-cascade method just to detect the localization of eyes and mouth . Last but not least please, i would need you to make a video conference with me after the completion of the project or just list out the segments of your coding to pdf by explaining them. So then i can use it to improve myself in programming. Down here is the sample of this app.
