Android Supporting Multiple Screens with fixed width icons

Question

This may not be explained the best but here it goes. I have a window of 2 by 2 square icons. I found a custom layout script that spaces these equally on the screen. These 4 icons consist of a square background with a little image and title. At the moment the width and height are defined in dp. But that stretches or shrinks the text. I am assuming I need to use fixed values. I understand that there are 4 generalised screen resolutions.

My question is, for small I would have to set the width and heights to x and y, but when the screen gets bigger due to larger devices I would have to increase x and y to keep some sort of continuity.

Is there a minimum and maximum width and height of screens for each size? How do other people get around these issues.

Sorry if it is a bit broad and sweeping, but I am new to creating dynamic (ish) displays for multiple resolutions.

Any help and advice will be greatly appreciated.

Google has actually documented this well. When you load your images in your res folder, you will need to simply put high, medium, and low res versions of your file into the file with the same name (but with hdpi and so forth appended to the name of the file). Android will handle which file to choose based on the screen size. I could go through how to do this, but this link covers the details of what I'm talking about in greater detail. Also, check out this question I answered a while back. It has a lot to do with your question.
