I'm trying to implement a launcher icon for an Android app. I'm using Android Studio's New Image Asset capability to create the icon from an image file and it works in most places except for the later Pixels.
On the Pixel 3XL, it looks like the following figure. The icon with a round white border around it.
On the Pixel 2, it looks the same
But on an original Pixel, it looks right:
I created the icon assets using the Android Studio New Image Asset capability. Selecting the image icon as shown in the following figure:
Then I set the background to the background color for the icon:
Based on what the UI shows, the icons all look right and Android Studio is supposed to generate the right files for all target platforms. Can someone please help me understand what I need to do to get rid of that white border on later phones?
You should add ic_launcher_foreground.xml and ic_launcher_background.xml to drawable file in your project. As far as I get it, you've try to make red background then add red backgorund layout you have only foreground image in this way. Btw that is not a bug that is a feature :)
You might be thinking this question is a duplicate of this one. But since then, Android Studio has been updated and the solution given there is not working anymore.
I am trying to set my app logo using image asset in android studio. This is because if I put my app logo directly in drawable or mipmap, then it causes many problems like: If it's size is big then app crash occurs, if device running on oreo then logo will not showed and default ic_launcher is showing etc.
While trying to set my app's logo using image asset, I am facing a problem:
I can't keep app logo's background transparent.
I have a png logo made in photoshop and I want to set this as my app logo and I don't want any background but android studio image asset doesn't provide any option to remove background. I tried following solutions from google:
this and this
but none of these worked for me.
Tried solutions:
By setting shape to none
by Deleting ic_launcher_background file from it's default location
Tried in different devices
None of these works...please help me. Any help will be appreciated.
Android 8.0 Oreo (API level 26) introduced adaptive launcher icons, which consist of two layers: a foreground and a background. The material design guidelines state that the background layer must be opaque in Android O and beyond, as you can see at the bottom of the following citation. So, the adaptive launcher icon for Android 8.0 or higher must have opaque background color at least, if targetSdkVersion of your app is 26 or higher.

Icons for Android
Android O and beyond
Android O icons represent your app on a device's Home and All Apps screens. The following guidelines describe how icons can receive unique visual treatments, animations, and behaviors.
...
Layer specs
Icons consist of two layers: a foreground and a background. Each layer can animate and receive treatments independently from the other layer.
Foreground (scrolling parallax)
108 x 108 dp
72dp masked section
Transparency recommended (optional)
Background (subtler parallax)
108 X 108 dp
72dp masked section
Must be opaque
Workaround for 7.1 or lower
Although launcher icons for 8.0 or higher must have opaque background color, the other legacy launcher icons for 7.1 or lower can revert to transparent background color, if you can omit round launcher icons from your app.
First, create Launcher Icons (Adaptive and Legacy). It will create adaptive launcher icons and legacy launcher icons. All of them have opaque background color, at first.
After that, create Launcher Icons (Legacy only). This will overwrite only the existing legacy launcher icons, as you can see in the second screenshot below. If you set the shape to none, they will have transparent background color.
Delete folder res/mipmap/ic_laucher_round in the project window.
Open AndroidManifest.xml and remove attribute android:roundIcon="#mipmap/ic_launcher_round" from the application element.
In the left-side pane above, the following XML files define adaptive launcher icons for Android 8.0 or higher.
mipmap-anydpi-v26/ic_launcher.xml
mipmap-anydpi-v26/ic_launcher_round.xml
As seen in the right-side pane, they refer to the following drawable XML files.
drawable/ic_launcher_background.xml
drawable-v24/ic_launcher_foreground.xml
Update #1:
In Android 8.0 or higher, the background color of launcher icons can be transparent, as shown in the Android 8.1 (Nexus 5X) screenshots. The sample app "NoAdaptive" is without any resource for the adaptive launcher icons in folder mipmap-anydpi-v26, and the other app "Adaptive" has the resource.
Update #2:
Although the background color of launcher icon can be transparent in Android 8.0 or higher, it depends on user’s launcher app. Some launcher apps will convert your legacy icon to opaque adaptive icon.
In Nexus 5X device (Android 8.1)
The default launcher app is Google Now Launcher, according to its package name com.google.android.launcher. The background color can be transparent, as in the screenshots of Update #1.
In Nexus 5 emulator (Android 8.1)
The default launcher app is Pixel Launcher, according to its package name com.google.android.apps.nexuslauncher. The background color can be transparent in Recents screen, as in the screenshots below:
opaque in Home screen
transparent in Recents screen
opaque in All Apps screen
Opaque white background in some launcher apps
These GMS apps are closed-source:
com.google.android.launcher Google Now Launcher
com.google.android.apps.nexuslauncher Pixel Launcher
In contrast, AOSP apps are open-source. Most launcher apps in Android are based on the source code of the following launcher apps:
com.android.launcher
Launcher (discontinued)
Launcher2 (legacy)
com.android.launcher2
Launcher2 (original package name)
com.android.launcher3
Launcher3 (for Android 5.0 Lollipop or higher)
Launcher3 source code
In the git branch oreo-release of Launcher3, LauncherIcons.java has the method wrapToAdaptiveIconDrawable that wraps legacy launcher icon in adaptive launcher icon.
/**
* If the platform is running O but the app is not providing AdaptiveIconDrawable, then
* shrink the legacy icon and set it as foreground. Use color drawable as background to
* create AdaptiveIconDrawable.
*/
static Drawable wrapToAdaptiveIconDrawable(Context context, Drawable drawable, float scale) {
if (!(FeatureFlags.LEGACY_ICON_TREATMENT && Utilities.isAtLeastO())) {
return drawable;
}
try {
if (!(drawable instanceof AdaptiveIconDrawable)) {
AdaptiveIconDrawable iconWrapper = (AdaptiveIconDrawable)
context.getDrawable(R.drawable.adaptive_icon_drawable_wrapper).mutate();
FixedScaleDrawable fsd = ((FixedScaleDrawable) iconWrapper.getForeground());
fsd.setDrawable(drawable);
fsd.setScale(scale);
return (Drawable) iconWrapper;
}
} catch (Exception e) {
return drawable;
}
return drawable;
}
The flag FeatureFlags.LEGACY_ICON_TREATMENT is defined in FeatureFlags.java:
// When enabled, icons not supporting {#link AdaptiveIconDrawable} will be wrapped in this class.
public static final boolean LEGACY_ICON_TREATMENT = true;
So, the background color of legacy launcher icon depends on this flag, and it can be opaque in some launcher apps such as Pixel Launcher.
The background color
If the flag is set to true, a new adaptive launcher icon is created with R.drawable.adaptive_icon_drawable_wrapper, and the existing legacy icon becomes its foreground layer. The background layer is a drawable: #color/legacy_icon_background, according to the resource XML file:
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<background android:drawable="#color/legacy_icon_background"/>
<foreground>
<com.android.launcher3.graphics.FixedScaleDrawable />
</foreground>
</adaptive-icon>
The color legacy_icon_background is defined in colors.xml
<color name="legacy_icon_background">#FFFFFF</color>
So, the background color becomes white.
In Android 5.0 an icon always got an opaque background until I created a transparent file.
File > New > Image Asset.
Turn to Launcher Icons (Adaptive and Legacy) in Icon Type.
Choose Image in Asset Type and select your picture inside Path field (Foreground Layer tab).
Create or download below a PNG file with transparent background of 512x512 px size (this is a size of ic_launcher-web.png).
In Background Layer tab select Image in Asset Type and load the transparent background from step 4.
In Legacy tab select Yes for all Generate, None for Shape.
In Foreground Layer and Background Layer tabs you can change trim size.
Though you will see a black background behind the image in Preview window, after pressing Next, Finish and compiling an application you will see a transparent background in Android 5, Android 8.
Here is the transparent image:
Try this way that worked for me:
First, create a launcher icon (Adaptive and Legacy) from Image Asset:
Select an image for background layer and resize it to 0% or 1% and
In legacy tab set shape to none.
Delete folder res/mipmap/ic_laucher_round in the project window and Open AndroidManifest.xml and remove attribute android:roundIcon="#mipmap/ic_launcher_round" from the application element.
Delete ic_launcher.xml from mipmap-anydpi-v26.
Note: Some devices like Nexus 5X (Android 8.1) adding a white background automatically and can't do anything.
If i didn't get you wrong you have a png file with 512x512 px from a Photoshop file and you want to make logo from it for all necessary folders (mipmap-xxxhdpi to mipmap-mdpi).
You can also use this after creating icon using Android Studio too. I prefer creating my icons using Photoshop.
I use this site after creating a 512x512px icon using Photoshop. You can have icons not only for Android also for iPhone apps and and more and it's free. Icons are scaled correctly, named, and placed inside mipmap folders under android folder of the zip file. You just unzip the file after downloading and copy and paste.I made 50 icons at least and never had a problem.
I have tried built in tools in android studio using res -> new -> Image Asset and then selecting notification icon.But after selecting the images it shows some grey and black boxes and not image icon and doesn't show in notifications as well.
I have researched and found that image background should be transparent for it to work but that didn't work also. Also i have tried images of 24x24 size as recommended but couldn't get the icon working in my android app.
Thanks in advance for any useful suggestions.
For v21 and above--> In notification icon, only white and transparent colors are allowed. Use white color what u want to show, rest part make it transparent.
For v20 and below --> You can use any image with proper dimensions.
Refer here for details.
I created an image in a 96x96 size, gave padding of 4px on all sides following this information.
Then I used Android Asset Studio to generate icons for different screens. But when I used these in my Notification Builder it is showing a grey box. Where am I doing wrong?
This is my image. Unable to display it here as background is transparent and image is white in color. Please download to see it.
I have the same problem. all my colors are white over transparent png, i still get plain white square on it. I checked the drawable folder have already generated 12 corresponding ic_stat_name.png file and they look as expected. But when i send notification the icon still appear white square.
I found the solution
Notification Icon with the new Firebase Cloud Messaging system
I use firebase notification which, according to the above source, will use the launcher icon instead of my expected ic_stat_name.png for notification
I have following issue, am developing an App for Android and I realise that the launch icon AKA ic_launcher is quite smaller than al the rest of the App that I got from GooglePlay.!see image below.. I tried as normal (on eclipse: new->android icon-set->....) using a 512x512 png file, then I gave a 2nd try using a recommended link I found by searching a solution (Android Asset Studio)
you may want to say " is not tooo much" but that is what I need, must be the same size as normal apps...
thanks in advance!
see the dotted line as reference to verify the size
Just create icon 512x512px without any generators, they add margins to a picture. You have to draw icon from border to border.
Use an existing application icon as a template, for example - mine
