Android app icon in background mode shows default icon initially

[Mr-Anonymous]

I created the adaptive icon for my Ionic 6 Android 10 App. The App Icon works, however when the App goes to background, it is showing the default Android App there initially. Only after closing the app and subsequent launches, the icon gets replaced with app icon. Why is that issue happens? Also doesn't cordova-res suppose to generate mipmap-anydpi-v26 icons as well?

My config.xml file looks like this:

       <icon background="resources/android/icon/ldpi-background.png" density="ldpi" foreground="resources/android/icon/ldpi-foreground.png" />
        <icon background="resources/android/icon/mdpi-background.png" density="mdpi" foreground="resources/android/icon/mdpi-foreground.png" />
        <icon background="resources/android/icon/hdpi-background.png" density="hdpi" foreground="resources/android/icon/hdpi-foreground.png" />
        <icon background="resources/android/icon/xhdpi-background.png" density="xhdpi" foreground="resources/android/icon/xhdpi-foreground.png" />
        <icon background="resources/android/icon/xxhdpi-background.png" density="xxhdpi" foreground="resources/android/icon/xxhdpi-foreground.png" />
        <icon background="resources/android/icon/xxxhdpi-background.png" density="xxxhdpi" foreground="resources/android/icon/xxxhdpi-foreground.png" />
        <splash density="land-ldpi" src="resources/android/splash/drawable-land-ldpi-screen.png" />
        <splash density="land-mdpi" src="resources/android/splash/drawable-land-mdpi-screen.png" />
        <splash density="land-hdpi" src="resources/android/splash/drawable-land-hdpi-screen.png" />
        <splash density="land-xhdpi" src="resources/android/splash/drawable-land-xhdpi-screen.png" />
        <splash density="land-xxhdpi" src="resources/android/splash/drawable-land-xxhdpi-screen.png" />
        <splash density="land-xxxhdpi" src="resources/android/splash/drawable-land-xxxhdpi-screen.png" />
        <splash density="port-ldpi" src="resources/android/splash/drawable-port-ldpi-screen.png" />
        <splash density="port-mdpi" src="resources/android/splash/drawable-port-mdpi-screen.png" />
        <splash density="port-hdpi" src="resources/android/splash/drawable-port-hdpi-screen.png" />
        <splash density="port-xhdpi" src="resources/android/splash/drawable-port-xhdpi-screen.png" />
        <splash density="port-xxhdpi" src="resources/android/splash/drawable-port-xxhdpi-screen.png" />
        <splash density="port-xxxhdpi" src="resources/android/splash/drawable-port-xxxhdpi-screen.png" />
        <hook src="hooks/copy_android_notification_icons.js" type="after_prepare" />
        <icon density="ldpi" src="resources/android/icon/drawable-ldpi-icon.png" />
        <icon density="mdpi" src="resources/android/icon/drawable-mdpi-icon.png" />
        <icon density="hdpi" src="resources/android/icon/drawable-hdpi-icon.png" />
        <icon density="xhdpi" src="resources/android/icon/drawable-xhdpi-icon.png" />
        <icon density="xxhdpi" src="resources/android/icon/drawable-xxhdpi-icon.png" />
        <icon density="xxxhdpi" src="resources/android/icon/drawable-xxxhdpi-icon.png" />

I saw this happen with my own testing of the new version of this tool (see #291), but it resolved itself after booting. I think it's just an oddity of Android when doing local development. I assume this is local?

Thanks for the clarification. I think you are right. Also I noticed I usually notice this android icon when my phone is connected to my mac while running the application for debugging. But once it's disconnected and when the app is relaunched another time, the correct app icon seems to be showing fine.

I will close this issue then in that case. Thanks for your comment @mlynch
