I'm working with Android Studio 1.1 Preview 1. I noticed that when I create a new project I'm getting the following hierarchy:
Mipmap folders for different DPIs, no more different DPIs drawable folders.
Should I put all my resources in the mipmap folders, or just the app icon?
The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.
Android introduced mipmap drawables for providing more flexibility to design the launcher icons. mipmap first introduced in Android Jelly Beans 4.3. If you are building different versions of your app for different densities, you should know about the mipmap resource directory.
Classic drawable resources such as images are stored in the drawable folder. In contrast, vector drawables are stored in drawable-v24 . For this project, keep the drawable default and click OK.
anydpi-v26: This is an additional filter over just anydpi. This says resources will always be picked up from anydpi-v26 regardless of devices density only if SDK/API level is 26 or higher(Oreo). So you can have mipmap-anydpi-v26 or drawable-anydpi-v26. All resource folders will follow above logic.

According to this Google blogpost:
It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.
When referencing the mipmap- folders ensure you are using the following reference:
android:icon="@mipmap/ic_launcher"
The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.
