It works on emulator devices and I can see themed icon. But on my real device, it doesn't seem to work while other apps are just fine. My real device is Pixel 6 Pro with the latest Android version. Emulators are also with the latest Android version. Themed icon feature is enabled on Pixel launcher.
Anyone faced such issue, I need help..
I created a monochrome version of the icon and added as asset and named ic_launcher_monochrome_foreground.png and updated ic_launcher.xml file in mipmap-anydpi-v26 as:
<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<background android:drawable="@color/ic_launcher_background"/>
<foreground android:drawable="@mipmap/ic_launcher_foreground"/>
<monochrome android:drawable="@mipmap/ic_launcher_monochrome_foreground"/>
</adaptive-icon>
But it only works on emulators. No release build can show the monochrome icon. I cleared the cache of Pixel Launcher on my phone, tried to restart it but none helps.
We had this issue as well, but realized we only added monochrome for the resource used by android:icon (in application-tag of our manifest) and not for the resource used by android:roundIcon.
