How to use Android Icons with _dp name?

So I am new to Android development. In iOS you can make a reference to an image "thing.png" and even though you have the following filenames iOS grabs the correct image per the screen res.

thing.png

I have icons in Android, from the material design download on GitHub, that are names as follows.

ic_cancel_18dp.png
ic_cancel_32dp.png
ic_cancel_48dp.png

My question is in Android can I just reference them like @drawable/ic_cancel.png and Android will grab the correct one per the screen res?

You only need to put your.png files in the relevant directory, and use the same name.

For example:

Rename all your files to ic_cancel.png.

  • In res/drawable-mdpi, put your old ic_cancel_18dp.png

  • In res/drawable-hdpi, put your old ic_cancel_32dp.png

  • In res/drawable-xhdpi, put your old ic_cancel_48dp.png

In your code, just use ic_cancel.png as reference to your image.

For more info, take a look at Using configuration qualifiers.
