A PNG image is to be used as the icon foreground, and the background should be completely transparent.
Using Android Studio > New Image Asset > Configure Image Asset dialog in the Asset Studio, virtually very combination of options for the background has been tried, including removing the file entirely from the path and deleting the background tags in ic_launcher.xml and ic_launcher_round.xml.
Removing the file from the path in this wizard and removing the tags from the XML files almost does the trick, but a faint black outline remains as the background (~alpha=20%). All other options for the Background Layer leave either a stark white or black background behind the foreground image when viewing the icon on the device's launcher.
Many apps manage to have a foreground only on their icons, so it is possible. What am I doing wrong here?
Update: Thank you for the quick comments! I tried both the solutions provided as answers, same result. Screen capture is uploaded as suggested.
Updating just the Legacy icon in the wizard is not sufficient, as that only changes the Legacy icon format. The newer "Adaptive" icons are required as well. Even if the background is set to a completely transparent square png, Android Studio changes it to white. If the background file is removed entirely, the wizard allows completion, but then Android Studio uses a slightly opaque black background, as shown. With respect to the uploaded image, there should be nothing behind the foreground, completely gray to in this case without any visible circle.

Method 1:
if you have a png, just copy it and paste it in drawable, and refer to image name from manifest.
<application
android:allowBackup="true"
android:icon="#mipmap/new_image"
android:label="#string/app_name"
android:roundIcon="#mipmap/new_image"
android:supportsRtl="true"
android:theme="#style/AppTheme">
....
</application>
Method 2:
Goto file > new > image asset, make sure you select a png image (with transparent background) & set background shape to none.
First you have a background image to get transparent icon without any background image you can't get your icon transparent .
And if you look to get image transparent you simply use some photo editor.
Get a view of the imageButton
View v = findViewById(R.id.myImageBtn);
get the icon from the app for example Chrome
pkgnam="com.android.chrome";
Intent intent1 = ctx.getPackageManager().getLaunchIntentForPackage(pgknam);
Drawable myIcon = getPackageManager().getActivityIcon(intent1);
set the background icon the same as the foreground icon
v.setForeground(myIcon);
v.setBackground(myIcon);

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 :)
I have an app on android that create home shortcut icon.
The image of the icon is image that i set programmatically from the drawable
Now the problem is, when the shortcut was created on the home screen it's created with white background.
How do i remove that white backgroubd and set image to full size of icon?
Thank you all..
EDIT: the app i was talking about is app that i developed using android studio and just want to set full size of image when i create home shortcut
This is highly dependent on the launcher you use. The image looks like the standard google android 8+ (?) icon shape.
I theory it could be part of the icon you created but since you are asking this I doubt it.
In older versions of android the outer shape of the icons were individual, while rather cool and the outline correctly shown while dragging them etc many complained about the lack of a uniform look of all the icons in the app drawer etc.
It was introduced to make all icons seem more uniform.
Long pressing an empty space in the Google Pixel launcher for example shows a choice to go into the settings for the launcher and there you can change the shape all icons should have:
In addition to this, apps can take advantage of the various shapes and adapt to them and fill them out so to speak. See for example the Chrome icon while changing the icon shapes in the launcher settings.
Introduced in android 8: The feature is called adaptive icons.
See the docs about adaptive icons here:
https://developer.android.com/guide/practices/ui_guidelines/icon_design_adaptive
That is because of adaptive icons - a feature of Android 8 and can't or shouldn't be changed. You can at best change the colour of the background.
i removed the white background from the launcher icon by following these guidelines https://developer.android.com/studio/write/image-asset-studio
a few more points
in the background layer, move the slider to resize the icon until you see no what would have been the white background.
in the manifest file, change the icons to reference the mipmap folder;
android:icon="#mipmap/yourlogo"
android:roundIcon="#mipmap/yourlogo"
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.
https://material.io/guidelines/style/icons.html#icons-icons-for-android
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 a PNG logo file that I want to display inside navigation drawer. But whenever I add the image asset to "mipmap", it adds white background and bounding boxes around the image. How to fix this?
Original Image:
After adding as image asset to Android Project's "mipmap" folder:
The 'mipmap' folder used ONLY be used for App icons. And these icons HAVE to have the same width and height. If they aren't, Android Studio will add extra white space to them.
Create a new icon that is square, but simply make some of the image transparent. Then you'll get your desired effect.
It is because the Shape property was set to Square by default. I changed it None, its fixed now. Thanks for responses.
Run the app - if it still shows - use PhotoShop to make the png.. your png is not made correcty
The problem is when you add it as an image asset as launcher icon it adds white background to the image sometimes if the image isn't of the specified size. Use this option only when you're adding launcher icon, use action bar and tab icons option that won't add any white background to the image, select the theme holo_light theme will make the image dark, and holo_dark theme will make the image white, don't worry you can change the color of image of any custom color by selecting the custom theme while uploading or, you can use the android:tint attribute in the layout file. And add app related graphics in the drawable folder only.
I'm using an image with transparency as a ImageButton in my Android app - but when it appears on the android screen - it still has a whitish surrounding border.
I even changed the image to one of the template ones supplied and that still is not transparent (although it is in photoshop).
Am a missing some declaration or something ?
I tried in both the emulator and also running on my phone and its still shows as white on the black background.
Cheers

The whitish color IS the button part of the image button :)
Use regular Button and set your image as the android:background of it. Don't set any text.
