Android Studio. Drawables folder and sizes? - android

I'm an Eclipse developer and recently switched to Android Studio.
I know that "drawable" folder is where I must upload all the images I'm going to use in my Android project but, what happens with the image sizes? In Eclipse there are different folders for each size (xxhdpi, xhdpi, hdpi...)
What method should I use now to get the best compatibility with images and devices?
Thanks.

In Eclipse there are different folders for each size (xxhdpi, xhdpi, hdpi...)
They are there in Android Studio too. The Android Tools team kinda hid them.
If you look just above the project explorer tree thingy on the left, you should see a drop-down, one that probably says "Android" right now:
That is the Android project view, one that gives you a somewhat synthetic look at your project, collapsing things like resource sets and sourcesets to hide those details.
Eclipse users will probably be happier with the classic project view, which you get by clicking that drop-down and switching it to "Project":
This works much like Eclipse's Package Explorer, where you get an actual filesystem view of what's going on, complete with resource set directories.
It's all the same stuff on the filesystem, but the Android project view masks it a bit.

Right click drawable -> New -> Image Asset -> Asset Type: Action Bar and Tab Icons. Image file: image_path, Resource Name: how_youre_image_will_be_called -> Next -> Finish
Done
This will add 4 different sizes of your image so that it will fit depending the device size (phone, tablet...)
You can also ctrl+c -> ctrl+v to drawable folder and pick the size you want (mdpi - phones, xxhdpi - tablets...) but it would not resize by devices type

Studio is generate image klasor automotacly.
just suld make like this.
ic_launcher 36*36
ic_launcher 48*48
and other image resizes.
But one thing changed.Now ldpi is dont create.

The easiest way is to use Resource Manager, it allows to upload our images from Android studio itself and then resize it with each density

Applying android app icon in Android Studio

I have started with Android Studio a few months before. I have found many good things and a few bad as compared to eclipse. I would like to know if there is a shortcut or easy way to change the app icon...like the Eclipse IDE offers automatically... or we still need to copy and paste the various icons (hdpi, mdpi, xxhdpi) manually to the respective directories.

Using Android Drawable Importer Plugin you can add an option to Android Studio to import drawables in different resolutions from Android Icons.

Theare aren't different drawable folders on Android Studio

I m trying to integrate different image size in my app but the problem is that in Android Studio there are not the drawable-Idpi,mdpi,hdpi,xhdpi folders.
I ve checked already other threads and the answers were that I just need to skip into the Project view instead of the Android one. But the results are the same. There is just one generale folder called drawable
And if I try to add another resource folders the drawable is missing.
Just create a new folder:
Right click 'res' folder --> New --> Android Resource Directory.
In the wizard, select drawable as 'Resource Type'. And then 'Density' from the resource qualifiers.
With regard to the 'mipmaps' folders, Android now prefers app icons in these folders because it can use an icon in a different density to the screen density.
More about mipmaps here: http://android-developers.blogspot.de/2014/10/getting-your-apps-ready-for-nexus-6-and.html
I had the same problem before.
I fixed it by downloading an icon that i wanted from http://www.icons4android.com/
now this site provides all the drawable-Idpi,mdpi,hdpi,xhdpi folders for download for each icon they have, I just highlighted all the drawable-Idpi,mdpi,hdpi,xhdpi folders, copied them, and then pasted them to android studio res folder.
(I did this in android view)
I hope this helps
You can create folder same as drawable, drawable-hdpi, mdpi, xxhdpi ... etc
Its look like
But when you see source code using
Add images in draweble its ask you in which folder you want to add(copy n past images in studio)
You can directly creat folder in res its also work...

How to manage drawable folder in Android Studio

I just moved Eclipse Based Android Project to AndroidStudio.
And I figure out drawable folders got combined.
My question is...
How can I change image(xhdpi) to image(hdpi)
And How can I add more image and Make folder base image.png.(like this screenshot).
If you don't see a drawable folder (xhdpi to hdpi) for the DPI that you need, you can create it yourself. There's nothing magical about it; it's just a folder which needs to have the correct name.
Curtsy Yole Sir
Change image folder (for example xhdpi to hdpi) is possible via right mouse click > refactor > move. And now you can select subfolder.

Android Development - Resizing images into drawable folders

Is there a way to get Eclipse to automatically re-size images and put them in the appropriate drawable folders? When you add an image for the icon when you first create an Android project, it automatically re-sizes the icon and puts them in the appropriate folders. I know you're meant to scale images using a 3:4:6:8 scaling ratio (http://developer.android.com/guide/practices/screens_support.html). I'm wondering if there is a way that Eclipse does this automatically for images?
For re-size icons, right click select New/Other… or press Ctrl+N, select Android Icon Set, the default name for icons is ic_launcher, click Next, in Foreground select Image and Browser that image like to put as icon and is re-sized automatically
Is there a way to get Eclipse to automatically re-size images and put
them in the appropriate drawable folders?
NO, until now, you have to create your own resources defined for every "Screen Density", tools like android_img_resizer will work but can´t support all densities, what if you need resources with mhdpi or tvdpi density.
More info:
Supporting Multiple Screens - Using configuration qualifiers
Designing alternative layouts and drawables
Supporting Different Densities
For re-sizing the images in bulk i will recommend you this tool https://github.com/bearstouch/android_img_resizer . its easy to install and it support the new resolutions (xxxhdpi,xxhdpi) as the base image.Check it out.

Set icon for Android application

How can I set an icon for my Android application?
If you intend on your application being available on a large range of devices, you should place your application icon into the different res/drawable... folders provided. In each of these folders, you should include a 48dp sized icon:
drawable-ldpi (120 dpi, Low density screen) - 36px x 36px
drawable-mdpi (160 dpi, Medium density screen) - 48px x 48px
drawable-hdpi (240 dpi, High density screen) - 72px x 72px
drawable-xhdpi (320 dpi, Extra-high density screen) - 96px x 96px
drawable-xxhdpi (480 dpi, Extra-extra-high density screen) - 144px x 144px
drawable-xxxhdpi (640 dpi, Extra-extra-extra-high density screen) - 192px x 192px
You may then define the icon in your AndroidManifest.xml file as such:
<application android:icon="#drawable/icon_name" android:label="#string/app_name" >
....
</application>
Add an application launcher icon with automatic sizing.
(Android studio)
Go to menu File* → New → Image Assets → select launcher icon → choose image file.
It will automatically re-size.
Done!
I found this tool the most useful.
Upload an image.
Download a zip.
Extract it into your project.
Done
https://romannurik.github.io/AndroidAssetStudio/
It's better to do this through Android Studio rather than the file browser as it updates all icon files with the correct resolution for each.
To do so go to menu File → New → Image Asset. This will open a new dialogue and then make sure Launcher Icons is selected (Which it is by default) and then browse to the directory of your icon (it doesn't have to be in the project resources) and then once selected make sure other settings are to your liking and hit done.
Now all resolutions are saved into their respective folders, and you don't have to worry about copying it yourself or using tools, etc.
Don't forget "Shape - none" for a transparent background.
Please don't edit my answer without asking.
Put your images in mipmap folder and set in manifest file...
like as
<application android:icon="#mipmap/icon" android:label="#string/app_name" >
....
</application>
App Folder Directory :
Icon Size & Format :
Place your images in drawables folder under either of the three and set it like this.
Code
<application android:icon="#drawable/your_icon" >
....
</application>
Right click your project, go to New > Other > Android > Android Icon Set
Then follow the instructions on the Wizard
1-Create Your icon in Photoshop Or Coreldraw by size 256*256
note that use PNG file format if you want to have a transparent icon
2-Upload Your icon in https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html
3-Set your setting on this site
4-Download the zip file automatically created by the webpage by clicking on download button
5-Extract the zip file and copy res folder to you project library
note that res folder contain all size icon
6-finally you need to set the manifest to use icon
<application android:icon="#drawable/your_icon" >
....
</application>
You can simply install an Android studio Martial icons plugin its name is please check plugin URL Material Design Icon Generator and check this GIF for more details:
This is mainly for creating the icons with required sizes, and it will be located directly in its folders.
I found all these answers that used to be solid answers to be a bit dated now. I reckon this will be the fate of this answer someday.
Click on your main project, most people would have "app" as their main project name by default. I like to be specific since I have other projects as well.
[your project name|app]->"New"->"Image Asset"
Then you will get to pick an image. I chose once that wasn't the greatest fit. Notice the tool shows you the "safe zone".
You can sample the different resolutions. Change the name, etc. The default name is "ic_launcher". I prefer to be expressive with the name so there is no confusion later which ic_launcher this belongs too.
Choose "Next", make changes if you need to, and ultimately "Finish". I found the rest of the tool to be self explanatory. For more info I suggest reading the manual that describes all these settings in more detail: Android Studio Image Asset Tool Documentation
On "Finish" this will put the files into the respective folders under the expected "res" folder.
The next thing you have to do is have to tell the project that's the icon you want to use. Inside the AndroidManifest.xml do something like the following (using your own name you chose to use above.)
<application
android:icon="#mipmap/pooflingers_ic_launcher">
That's pretty much it, as of today anyway... I am using Android Studio v4.2.1 Let me know when these steps become out of date.
You have to follow steps like:
You will see your default icons ic_launcher.png like:
You have to change all the images which are in mipmap-xxxx folders.
First of you have to create your own logo or pick up image that you want to place as icon of launcher and upload here Android Asset Studio - Icon Generator - Launcher icons, You will get all the set of mipmap-xxxx and web_icon also from that link.
Now you have to copy all the folders which are in side of res folder,
Now go to Android Studio Project -> Right click on res folder -> Paste. It will prompt you like File 'ic_launcher.png' already exists in directory, You can press Overwrite all. It will paste/replace images in respective folder.
Now you can run and see your application icon with new image.
Happy Coding :) :)
Choose icon picture copy this pic
Paste it into your project's res/drawable folder
Open manifest file and set
Run program
If you have an SVG icon, you can use this script to generate your android icon set.
In AndroidManifest change these :
android:icon="#drawable/icon_name"
android:roundIcon="#drawable/icon_name"
Define the icon for android application
<application android:icon="drawable resource">
....
</application>
https://developer.android.com/guide/topics/manifest/application-element.html
If your app available across large range of devices
You should create separate icons for all generalized screen densities,
including low-, medium-, high-, and extra-high-density screens. This
ensures that your icons will display properly across the range of
devices on which your application can be installed...
Size & Format
Launcher icons should be 32-bit PNGs with an alpha channel for
transparency. The finished launcher icon dimensions corresponding to a
given generalized screen density are shown in the table below.
Place icon in mipmap or drawable folder
android:icon="#drawable/icon_name" or android:icon="#mipmap/icon_name"
developer.android.com/guide says,
This attribute must be set as a reference to a drawable resource
containing the image (for example "#drawable/icon").
about launcher icons android-developers.googleblog.com 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. For example, an xxxhdpi app icon can be
used on the launcher for an xxhdpi device.
Dianne Hackborn from Google (Android Framework) says,
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.
For launcher icons, the AndroidManifest.xml file must reference the mipmap/ location
<application android:name="ApplicationTitle"
android:label="#string/app_label"
android:icon="#mipmap/ic_launcher" >
Little bit more quoting this
You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.
You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.

A bit old, but for future use:
Open Android Studio -> app/src/main/res -> Right Click -> Image Asset
Goto File->new->ImageAsset.
From their you can create Image Assets for your icon.
After that we will get icon image in mipmap different formats like
hdpi,mdpi,xhdpi,xxhdpi,xxxhdpi.
Now goto AndroidManifest.xml
<application android:icon="#mipmap/your_Icon"> ....</application>
