Question

before when I was creating a new project I was found this folders drawable-hdpi,drawable-mdpi, drawable-xhdpi, and drawable-xxhdpi. but now they are all gone!

is there any explanation of what happens?

and where we should put our images?

Answer 1

This is perhaps because they will add an Gradle plugin that converts SVGs to PNGs during build (as mentioned in this IO talk ). The idea is that you will only need to have a single SVG instead of multiple PNGs for various densities (an thus, only one drawable folder). You can still create the folders and use PNGs.

The Gradle plugins for SVG conversion by Google has not been released yet, but you can use Victor or a similar plugin if you already want to use SVGs for your drawables.

Answer 2

You should read Android Blog
you can just create drawable-xhdpi.

I just give answer here
read and if any problem ask.

Answer 3

I wasn't aware that Android Studio ever provided these dpi dependent drawable folders for the built-in default project scaffolding, and indeed, why should they?

Are they supposed to guess that you're going to support each and every one of these resolutions? Perhaps all your graphics will be vector graphics? Perhaps you only target low or high resolutions?

Also, the DPI modifier is only 1 of the possible modifiers you can attach to a resource folder. You can also add locale, screen width / height, mobile country code and many more. Should Android Studio create a folder with each of these options, along with every possible variation? You'd end up with thousands of folders which you'd likely never use.

In addition, creating a folder with no assets inside it is a big problem when you start synchronising your code using Github or something similar, and creating every possible folder with default assets inside seems like a huge waste.

I think the best approach here is to create any resource folder you need when you need it. Google leaves this decision to you.

Also, important: There is no XDPI or XXDPI folder - it's X H DPI, and XX H DPI
