As of API 26 and above, Android supports adaptive launcher icons, as such.

Here is how to implement adaptive icons in your Kivy application and export it using buildozer.

Generate Background and Foreground images (.png/.xml, as prescribed in link above). Background must cover the entire image (no transparency). Foreground can have transparency; 72dp on all 4 edges of the foreground will be cut off.
Open a New Project in Android Studio

Select app folder
Click File --> New --> Image Asset
Upload the Background and Foreground you generated.

Adjust as needed, and follow buttons to create the proper icon. Leave default name "ic_launcher".

Copy contents of the res folder in your app in Android Studio (minus values and values-night) to ~[app_name]/.buildozer/android/platform/python-for-android/pythonforandroid/bootstraps/sdl2/build/src/main/res. Click and drag, "merge" folder contents if prompted.

In ~[app_name]/.buildozer/android/platform/python-for-android/pythonforandroid/bootstraps/sdl2/build/templates/AndroidManifest.tmpl.xml

Line 59: android:icon="@drawable/icon" TO

android:icon="@mipmap/ic_launcher"

android:roundIcon="@mipmap/ic_launcher_round"

Line 100 (now 101): android:icon="@drawable/icon" TO (same as above)

android:icon="@mipmap/ic_launcher"

android:roundIcon="@mipmap/ic_launcher_round"

Remove icon.filename from buildozer.spec
