Update: VeinSeek 2 is here!

VeinSeek for Android is Android's answer to the popular iOS app, VeinSeek Pro. 

VeinSeek takes advantage of multispectral imaging principles and the intrinsic optical properties of skin to produce enhanced images of veins; it does so by boosting oxyhemoglobin/deoxyhemoglobin absorption contrast and reducing the contribution of superficially-scattered and specularly-reflected light to the overall image.
VeinSeek for Android is incredibly simple. Your smartphone's flash will be activated on opening the app. Point your phone at the site you want to image. You can adjust the depth of the effect using the slider bar. You can also turn the effect on and off using the switch at the top of the screen. That's it! Happy vein-finding!
