Android studio: points scoring, obsticle overlap with game over on overlap 24 hours.

I need a 2D (top view, straight road) racing game Android app. I already have main menu screen, difficulty screen, all ui graphics in drawable nodpi folder, opengl render class created, seperate texture objects for car, background, accel pedal and brake pedal. Steering functionality is sensor recognition. Required: completed in android studio Obsticle detection, basic points system (increment of + 1000) Game over and high score functionality Points keeping functionality. Graphics of correct equations on car overlap event gives 1000 points, Graphic of incorrect equations on car overlap event creates game over and goes to highscore activity screen. Currently no overlap events or obsticle classes
