Adaptive icon does not cover default black background

[kamilchlebek]

I noticed small issue when trying to setup splash screen on Android >= 12.

Namely there's a little bit of black color on the edges of the icon.

The issue is related with #424 which added android:inset="16.7%" to the foreground & background.
I suppose that due to calculation inaccuracy (1/6 ≈ 16.7%), the background is too small and doesn't cover default background that lies underneath.

Workaround

Change: android:inset="16.7%" to android:inset="16.6%"

Actual (left), Expected (right)

Here's a StackOverflow thread that describes how are icons rendered:

It links to android source that explains where does that black color come from:

we have the same issue, generated icons for android are useless

I didn't get the workaround, the inset... I'm using capacitor and I'm experiencing the 1px black line at right and botton of icon.
I would like to know how should I update my AndroidManifest.xml with:
android:inset="16.6%"

I did the workaround, but have to manually edit while capacitor-assets is not fixed.
I've found the android:inset in those two files in a search with grep:

grep -r 'android:inset' android/app/src/main/res

android/app/src/main/res/mipmap-anydpi-v26/ic_launcher_round.xml:        <inset android:drawable="@mipmap/ic_launcher_background" android:inset="16.7%" />
android/app/src/main/res/mipmap-anydpi-v26/ic_launcher_round.xml:        <inset android:drawable="@mipmap/ic_launcher_foreground" android:inset="16.7%" />
android/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml:        <inset android:drawable="@mipmap/ic_launcher_background" android:inset="16.7%" />
android/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml:        <inset android:drawable="@mipmap/ic_launcher_foreground" android:inset="16.7%" />

So, after the changes to 16.6% it worked!

This worked for me!
