I use a tool called Android Icon Set in the Eclipse for standard icons like Launcher  ActionBar  Tab icons and notification icons  You can launch it from File --  New --  Other   --  Android --  Android Icon Set  The best part is that you can choose any file from your computer and it will automatically place all the images of standard sizes into your project directory

Just use https   romannurik github io AndroidAssetStudio index html  It can make a set of icons from an image  later you can download a zip-file  Or download a Windows application at https   github com redwarp 9-Patch-Resizer releases  doesn t need to install  and open an icon  Also you can use a plugin Android Drawable Importer  see answers above  Because it is abandoned  install forks  See Why does Android Drawable Importer ignore selection in AS 3 5 onwards or https   github com Vincent-Loi android-drawable-importer-intellij-plugin  https   appicon co  image-sets

There is also the possibility to use the Vector Asset Studio in combination with Scalable Vector Graphics  SVG   Android Studio will handle the rest for you  As the official documentation says      Vector Asset Studio helps you add material icons and import Scalable   Vector Graphic  SVG  files into your app project as a drawable   resource  Compared to raster images  vector drawables can reduce the   size of your app and be resized without loss of image quality  They   help you to more easily support different Android devices with varying   screen sizes and resolutions because you can display one vector   drawable on all of them    I consider this the future approach

Use Android Studio Image Asset  Go to    Project gt res -- gt  right click   new gt  image asset   Then set   -Icon type  Launcher Icons -Asset type  Image -Path  the path to your image -Trim  No -Padding  0  -Shape  None -Effect  None   Select  Next Finish   Now you will have your icon in the correct resolutions      EDIT  I recommend to use SVG images to create Vector Drawables  and then use them in a canvas to resize them to the correct size or simply change the DP   You can get the default icons from Google or just create your Own    Project gt res -- gt  right click  new gt  vector asset   Then set   -Asset type  Local file  SVG  PSD  -Path  the path to your image -Size  check Override to keep your aspect ratio  -Chek enable auto mirroring for RTL Layout    Select  Next Finish   Now you will have your icon and you will be able to change size  color etc

Not 100  automatic  but I save a lot of time using Photoshop Actions    For instance  given xhdpi assets  I then create a task for hdpi and mdpi  that scales to 66 66  and to 44 44  respectively  Then I run the actions for all images on folder xhdpi   For 512x512 images  all you have to do is calculate which percentage should you scale your images to achieve xxhpi  xhdpi  hdpi  and mdpi

Update    The plugin previously mentioned has been abandoned  but it apparently has an up-to-date fork here   Old Answer   I use the Android Studio plugin named Android Drawable Importer     To use it after installed  right click your res drawable folder and select New  gt  Batch Drawable Import   Then select your image via the   button and set the Resolution to be xxhdpi  or whatever the resolution of your source image is

Option  1  Just ship the -xxhdpi drawables and let Android downsample them for you at runtime  downside  will only work on fairly recent devices  where -xxhdpi is known   Option  2  Use Android Asset Studio to downsample them for you  Option  3  Automate the process within a graphics editor  per ssantos  answer  Option  4  Script yourself a solution  using something like ImageMagick  Option  5  Use image baker

[android] Is there a way to create xxhdpi, xhdpi, hdpi, mdpi and ldpi drawables from a large scale image?

Update:

If you want quick and easy way visit https://www.img-bak.in/ or https://appicon.co/ they work with iOS as well.

I will try to explain the process in step wise basis, so that it will be simple to understand to anyone.

1. Install the plugin manually as provided in the ReadME

2. Restart android studio

3. As you can see in the following screencap, there is only one drawable here

4. Now right-click on the drawable folder and navigate to New>Batch Drawable Import

5. Now select "the Single " image you want different variations of drawables.

6. Now select which dimension the origin image is. If the origin image is xxhdpi like in my case select "xxhdpi " as "Source Resoultion".

7. Now press ok then ok again ..and then it will take few seconds and then you will magically get all the variables of the drawables.
