[android] Android - Launcher Icon Size

For HDPI, XHDPI, etc. what should be the ideal size of the launcher icon? Should I have to create 9-Patch images for the icon to scale automatically, or would it be better to create separate icons?

No need for third party tools when Android Studio can generate icons for us.

• File -> New -> Image Asset

• Then choose Launcher Icons as the Asset Type:

• Choose a High-res image for the Image file:

• Next -> Finish to generate icons

Finally update android:icon name field in AndroidManifest.xml if required.

Launch image and Slash image size for Google Play Store app submission

1. High-res icon. PFB the table for required sizes 32-bit PNG (with alpha), Dimensions: 512px by 512px, Maximum file size: 1024KB

Required Launch Icon And Splash Image size

2. At least 2 screenshots are required overall (Max 8 screenshots per type, Types include "Phone", "7-inch tablet" and "10-inch tablet”). JPEG or 24-bit PNG (no alpha), Minimum dimension: 320px, Maximum dimension: 3840px, Sample sizes: 320 x 480, 480 x 800, 480 x 854,1280 x 720, 1280 x 800 24 bit PNG or JPEG

According to the Material design guidelines (here, under "DP unit grid"), your product icon should be of size 48 dp, with a padding of 1dp, except for the case of XXXHDPI, where the padding should be 4dp.

So, in pixels, the sizes are:

• 48 × 48 (mdpi) , with 1 dp padding
• 72 × 72 (hdpi), with 1 dp padding
• 96 × 96 (xhdpi), with 1 dp padding
• 144 × 144 (xxhdpi), with 1 dp padding
• 192 × 192 (xxxhdpi) , with 4 dp padding

I recommend to avoid using VectorDrawable as some launchers don't support it, but I think WEBP should be ok as long as you have your minSdk support transparency for them (API 18 and above - Android 4.3).

If you publish on the Play Store, the requirement to what to upload there are (based on here) :

• 32-bit PNG (with alpha)
• Dimensions: 512px by 512px
• Maximum file size: 1024KB

I've posted a script for generating all platform icons for PhoneGap apps from a single SVG icon file. If you have existing bitmaps, I also include some notes that may help you to generate the SVG vectors from an existing bitmap. This won't work for all bitmaps but may for yours.

You can create icons directly in the android studio itself.The Steps you need to follow are:

1.Right click on Res->New->Image asset

2.CHange asset type to image.

3.Load the image from the local disk

4.You have options to trim,change padding and add background also.Change the values if you need.

5.click Next->Finish.

The image wil be automatically added to mipmap-mdpi,mipmap-hdpi,mipmap-xhdpi,mipmap-xxhdpi,mipmap-xxxhdpi if you select launcher icon or drawable-mdpi,drawable-hdpi,drawable-xhdpi,drawable-xxhdpi,drawable-xxxhdpi ifyou select other icon optins.

Adaptive Icons

Starting with Android 8.0 there are adaptive icons, which are made up of two separate layers. Both layers are 108 x 108 dp.

(image adapted from Android documentation)

Sizes

If you are supporting versions below Android 8.0, you still need to include the legacy sizes (48dp). I marked the pixel sizes in red for each resolution below.

Don't do it by hand

I suppose you could make all of those by hand if you want to, but I have to say that my days of doing that are over. The Android Studio 3.0 Asset Studio is quite good and will generate them all for you. All you have to do is supply a sufficiently large foreground and background image. (I used a 1024 x 1024 px image).

To open the Asset Studio go to File > New > Image Asset.

I would create separate images for each one:

LDPI should be 36 x 36.

MDPI should be 48 x 48.

TVDPI should be 64 x 64.

HDPI should be 72 x 72.

XHDPI should be 96 x 96.

XXHDPI should be 144 x 144.

XXXHDPI should be 192 x 192.

Then just put each of them in the separate stalks of the drawable folder.

You are also required to give a large version of your icon when uploading your app onto the Google Play Store and this should be WEB 512 x 512. This is so large so that Google can rescale it to any size in order to advertise your app throughout the Google Play Store and not add pixelation to your logo.

Basically, all of the other icons should be in proportion to the 'baseline' icon, MDPI at 48 x 48.

LDPI is MDPI x 0.75.

TVDPI is MDPI x 1.33.

HDPI is MDPI x 1.5.

XHDPI is MDPI x 2.

XXHDPI is MDPI x 3.

XXXHDPI is MDPI x 4.

This is all explained on the Iconography page of the Android Developers website: http://developer.android.com/design/style/iconography.html

Don't Create 9-patch images for launcher icons . You have to make separate image for each one.

LDPI - 36 x 36
MDPI - 48 x 48
HDPI - 72 x 72
XHDPI - 96 x 96
XXHDPI - 144 x 144
XXXHDPI - 192 x 192.
WEB - 512 x 512 (Require when upload application on Google Play)

Note: WEB(512 x 512) image is used when you upload your android application on Market.

Well as @MartinVonMartinsgrün mentioned Now there is exists Better tools then assert generator in android studio

For application Icon ( Toolbar , ActionBar , DrawableLeft etc ) Use : http://romannurik.github.io/AndroidAssetStudio/icons-actionbar.html

For launcher (Application Icon ) Use : https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html

But Here are some tricks and way to get the better resolution for icons and launcher icons.

Step 1 :

First go to the https://materialdesignicons.com and choose your icon . Or if you have your icon in good resolution then skip this step . Click the desired icon and click on "Advanced Export" it will open up a window like this below

Then click the "Icon" to generate icon (.png) . Well the trick is try to generate as large icon as possible for high resolution devices and the tools will handle it all for small devices but if you use small icon , while generating the icon for high end devices you will loose the icon resolution .

Step 2 :

Then go the Tools page and Upload the Icon

Click the "Custom" if you want to color your icon . No matter what color of icon you are uploading , by using Custom you can generate any color you want . Then choose a name and click "Download .ZIP" . This will download the .zip file with the icon for most of the common resolution . You can copy and paste the res folder in your application project folder and you will see the icon in the drawable section .

I had the same problem but then realized the arrangement of my icon graphic within the square allowed (512 x 512 in my case) was not maximized. So I rotated the image and was able to scale it up to fill the corners better. Then I right clicked on my res folder in my project in Android Studio, then choose New then Image Asset, it took me through a wizard where I got to select my image file to use. Then if you check the box that says "Trim surrounding blank space", it makes sure all edges, that are able, touch the sides of your square. These steps got it much bigger than the original.

LDPI should be 36 x 36.

MDPI 48 x 48.

TVDPI 64 x 64.

HDPI 72 x 72.

XHDPI 96 x 96.

XXHDPI 144 x 144.

XXXHDPI 192 x 192.

Android icons require five separate sizes for different screen pixel densities. Icons for lower resolution are created automatically from the baseline.

mdpi (Baseline): 160 dpi 1×
hdpi: 240 dpi 1.5×
xhdpi: 320 dpi 2×
xxhdpi: 480 dpi 3×
xxxhdpi: 640 dpi 4× (launcher icon only)

Launcher icons (.Png)

48 × 48 (mdpi)
72 × 72 (hdpi)
96 × 96 (xhdpi)
144 × 144 (xxhdpi)
192 × 192 (xxxhdpi)
512 × 512 (Google Play store)

Action bar, Dialog & Tab icons

24 × 24 area in 32 × 32 (mdpi)
36 × 36 area in 48 × 48 (hdpi)
48 × 48 area in 64 × 64 (xhdpi)
72 × 72 area in 96 × 96 (xxhdpi)
96 × 96 area in 128 × 128 (xxxhdpi)*

Notification icons

22 × 22 area in 24 × 24 (mdpi)
33 × 33 area in 36 × 36 (hdpi)
44 × 44 area in 48 × 48 (xhdpi)
66 × 66 area in 72 × 72 (xxhdpi)
88 × 88 area in 96 × 96 (xxxhdpi)*

Small Contextual Icons

16 × 16 (mdpi)
24 × 24 (hdpi)
32 × 32 (xhdpi)
48 × 48 (xxhdpi)
64 × 64 (xxxhdpi)*

The xxxhdpi size needed only by the launcher icon as the Supporting multiple Screens official site says.

Provide at least an 512px X 512px image and use this tool: https://romannurik.github.io/AndroidAssetStudio/icons-launcher.html

It will generate all icons for you in the correct size, inclusive the web image for the play store.
