reflective shader on android

hi , I have a car model which has some nice "Reflective/Bumped Specular" shader . but when I export it to my android phone , it seems that android doesn't support my shader, and the car looks so fake this way . I wanted to know if there's any solutions to this . It also seems that android doesn't support "Directional lights" and I have to use so many point lights for lightening my scene and I think it uses much more processing on the device .
thanks
