Build me an Android app that can recognize vehicle number plates from a phone camera photo.

I want the user to be able to open the app, capture or choose an image of a vehicle, have the app find the license plate area, process the image, and show the recognized plate characters clearly on screen. It should work as an automatic number plate recognition demo for smartphones, with support for international plates where possible and especially good results for European style plates if the sample data supports it.

Use image processing for locating the plate and cleaning up the image, then use a trained recognition approach for reading the characters. Keep it simple and research friendly, so someone can test images, see the detected plate, and see the final text result. This is an older Android Java style project, so make it runnable as an Android app and update anything needed to build if required. Look up current Android or OpenCV docs online if you need to.
