I am using Android Studio version 1.2.2 and this how my res folder looks:
As you can see there are no drawable folders present.
My concern:
Is the drawable has been deprecated and instead of it I have to place all the images used in the app in mipmap folders.
If I need to create the selectors or any shape for a view I need to place it in the "drawable" or the "mipmap".
Does anyone has clue about it?

mipmap folders are for placing your app icons in only and in case of drawer folder, any other drawable assets you use should be placed in the relevant drawable folders as before.
You should go through Google Blog which says
"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."
If I need to create the selectors or any shape for a view I need to place it in the "drawable" or the "mipmap"
Just create drawer folder if you want to use selectors.
if you are building different versions of your app for different densities, you should know about the "mipmap" resource directory. This is exactly like "drawable" resources, except it does not participate in density stripping when creating the different apk targets.
But if you want to use selectors than you can create a drawable folder..

I'm new to Android programming. I was working for UI design stuff using Adobe XD and I exported the stuff I created to Android Studio. I was following this tutorial. And I was trying to use the stuff in drawable folders I created. (like drawable-hdpi) But the stuff that is stored in these folders doesn't show up. Only images that are stored in drawable folder show up. What am I wrong with this?
I mean the files doesn't show up as a suggestion and on this list.
This is the normal behavior.
Folders like drawable-hdpi or drawable-mdpi should contain the same as per name drawables as the drawable folder but with different resolutions.
When you choose a drawable in code or resources you see the drawables contained in drawable folder but at run time depending on the resolution of the emulator/device another drawable with the same name as the original from the other drawable-xxxx folders will be used.
In the dialog in the image you posted if you click on project you may see drawables from the other folders and choose them, but it's always a good practice to use the Drawable folder too.
I created one project in android studio, android studio didn't create drawable folder density wise as like it used to drawable-hdpi, drawable-mdpi etc. It created mipmap-hdpi, mipmap-mdpi etc.
I read https://stackoverflow.com/a/28065664/2455259 mipmap directory is for launcher icons.
Any other drawable assets you use should be placed in the relevant drawable folders as before.
Then why Android Studio stopped to create drawable folder as like before ? Is it no longer recommended approach to put app resources in drawables ?
It wants you to create them when you need them, you can create one by right clicking on the res folder and then click on add new resource directory, select the drawable as the resource type and then from the list of available qualifiers chose density and then the >> button, then select the density you want.
I think a reason why it was removed is for consistency because density is just one of the many qualifiers you can add to a resource file.
It also makes the folder structure neat, because you might not be using all the drawable folders.
The reason why it created the mipmap-hdpi, mipmap-mdpi folders is because there is already a file in it which is the default launcher icon for a new app, if there was no item in it it would not have created them.
The mipmap folder is used for icons only. The other resources have to be placed in correspond drawables' folders.
It is needed for better icon rendering.
I am trying to include variations of an icon's size in my Android Studio res/drawable folder. I downloaded the icon that I wanted from material.io/icons and placed the different variants of the icon into my drawable folder.
Here is the drawable folder:
However, in Android Studo, there are no drawables found.
I am having trouble understand why this is happening because I have already created another app with images of differing sizes. That app here.
Instead of creating a drawable folder and placing each separate image into the folder, copy and paste each variant into the res directory.
Under the Project pane (on left hand side), if you have selected 'Android' menu then you can't see the different drawable folders as it merges all the folders in one. If you change the menu to 'Packages' then you would be able to see all the folders you have created manually.
Create All the drawable folders inside the res folder outside the sudio and just refresh the project inside the android studio.
As you said that you have included the icons in the drawable folders according to resolutions , so if you want to see if the icons are present in the drawable folders . You need to change the menu from "Android" to "Packages" , you should see different drawable folders and icons in the respective folders .
I have read this article on mipmap before going through mipmap practically to understand its concept over drawable.
What i've faced is,
While working with mipmap layout-preview is not correct, while using image from mipmap folder.
Is mipmap only for launcher icon ? do i need to manually create all drawable folders(drawable-hdpi, drawable-mdpi etc.) for all other View's (Button, ImageView, etc.) image? If so then why don't android studio is not creating all drawable folder after creating new project?
I've also searched this issue but failed to get any useful or relevant link. I don't know what's wrong with mipmap because it seems fine while run code only layout preview is not correct.
Update :
Currently for workaround i've used mipmap folder only for launcher-icon and for all other Views i've manually created drawable-mdpi, drawable-hdpi etc.
to make layout-preview fine.
Please help!
According to this Google Post
The mipmap folders are only for placing your app icons.
Any other drawable resources(images and drawable .xml) you use should be placed in the relevant drawable folders as before Android 4.3.
This is the 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.
For referencing the mipmap - folders ensure you are using the
following reference: android:icon="#mipmap/ic_launcher"

Yes they are talking about the Launcher icon for the Nexus family. So this would be good practice if you do so. And for other resources you have to keep going in the same way As you always do.
In Android Studio, when a project is created it includes a bunch of drawable folders, but each with a suffix indicating their size.
For example, there's
drawable-mdpi
drawable-hdpi
drawable-xhdpi
...
However, very often I see instructions to add something to the drawable folder. For example, in the Android documentation about selector xml resources, here.
Should I add a drawable folder without a suffix? Or should I add the xml file to all of the different drawables? Why is there no plain drawable from the beginning?
You can add drawable folder without any suffix for selectors or some nine patch images which you want to be generic but drawable folder without suffix is basically for selectors only.
Android studio or eclipse does not provide it while project creation coz it doesnt know your pre requirement for these thing.
So there is no harm in creating the folder of your own.
while developing in eclipse there was no folder for fonts or xml folder for widget but you can create these folders on your own.
You can use drawable folder without any suffix. Also? if you have owner file used on any screen, you can set image to own of any drawable folder with any suffix.
