Can't get DAB to accept both adaptive and legacy icons

I can’t get DAB to accept both adaptive and legacy icons for my app √Root Korean: A Hanja Dictionary which is available at

For example, the folder on my computer containing the hdpi version of my app’s icon has three files: “ic_launcher.png,” “ic_launcher_foreground.png,” and “ic_launcher_round.png.”

However, the “72 x 72” version of my app’s icon in the section “App Icon
Android” of the the tab “Images” in DAB only uses my “ic_launcher.png” file
and ignores the other two files.

I could only get each category (like “72 x 72”) to accept one image (like “ic_launcher.png”) and only one image.

Can you fix this issue in the next update?

Here is some helpful information about adaptive and legacy icons:

The webpage #launcher says, “Adaptive launcher icons can display as a variety of shapes across different device models and are available in Android 8.0 (API level 26) and higher. Android Studio 3.0 introduces support for creating adaptive icons using Image Asset Studio. Image Asset Studio generates previews of an adaptive icon in circle, squircle, rounded square, and square shapes, as well as a full bleed preview of the icon. Image Asset Studio also generates legacy, round, and Google Play Store previews of the icon. A legacy launcher icon is a graphic that represents your app on a device’s home screen and in the launcher window. Legacy launcher icons are intended for use on devices running Android 7.1 (API level 25) or lower, which don’t support adaptive icons, and don’t display as varying shapes across device models.”

You can read more about adaptive icons at /icon_design_adaptive.html and icons at /icon_design.

I changed this to a feature request.

Never mind “both”; I cannot find anything about the no-longer-new adaptive icons for DAB.

Can you clarify what you mean by your post? Are you saying that you also can’t get DAB to accept adaptive icons?

Yes, I had gotten exited by your title, by reading (probably my fault to do with English) that you already manage to use either legacy icons or adaptive icons but not yet both.

I have not found a way to use adaptive icons in DAB. But file size matters in Africa, where internet is still expensive and slow.

So since Google is starting to make dedicated packets for different Android versions respectively, users of Android 8 and beyond could get smaller downloads with adaptive icons. I will follow this development with interest.

At the moment I am struggling with the Asset Studio inside Android Studio. It always wants to add massive margins of transparency and does not comply with the new rules for Google Play icons, see my other post here:

I see. Yes, I have been able to use legacy icons with DAB because a legacy icon consists of only one image layer. I can’t get DAB to accept both image layers of adaptive icons (bottom layer and top layer). It can only accept one image layer. The problem is that DAB only accepts one image layer in each category (like hdpi).

If you wanted an app created with DAB to have both adaptive and legacy icons, it would have to have two sections for each category, one section that contains the two image layers for the adaptive icon and one section that contains the image for the legacy icon. I hope that this is implemented in a future version of DAB.

It’s important for an app to have adaptive and legacy icons because there are many different versions of Android that can be run on an Android phone. You can see information about users’ adoption of Android versions at

I have the same problem with Image Asset Studio. I hope they update it in the future to be compliant with the new icons you discussed in your post Warning about Google Play icons: changed rules. Let me know if you figure out that issue with Image Asset Studio.

Android Adaptive icons will be supported in Dictionary App Builder 6.0, to be released in the next few days.
