[Android] Failed to inflate ColorStateList - error fix for CheckBox

[kubaflo]

Description

In the styles.xml file, I noticed that Widget.Material3.CompoundButton.CheckBox is set as the parent for MauiCheckBox. However, Maui.MainTheme has Theme.MaterialComponents.DayNight as its parent.

After changing the parent of Maui.MainTheme to Theme.Material3.DayNight.NoActionBar, the error disappeared, but I had some reservations about whether that was the right solution.

So I dug deeper and found in src/Core/AndroidNative/maui/build/intermediates/incremental/release/mergeReleaseResources/merger.xml the following code

<style name="Base.Widget.Material3.CompoundButton.CheckBox" parent="Widget.MaterialComponents.CompoundButton.CheckBox">
    
    <item name="android:textAppearance">?attr/textAppearanceBodyMedium</item>
    <item name="errorAccessibilityLabel">@string/error_a11y_label</item>
    <item name="buttonTint">@color/m3_checkbox_button_tint</item>
    <item name="buttonIconTint">@color/m3_checkbox_button_icon_tint</item>
    <item name="buttonIcon">@null</item>
</style>

It can also be set to @null

I think colorPrimary is defined in the templates only? What will happen if you were to remove it?

Maybe @null or anything else may be better? Of does this color always exist in a plain android app with no styles or colors?

I see it at the top of the file...

Hi,
i updated nightly to version 8.0.90-ci.net8.24459.1 and the problem persists. Do I need manual changes in existing projects?

Looking at timestamps, it looks to me that 8.0.90-ci.net8.24459.1 was compiled before this fix was merged.

Ah okay. I will try again tomorrow.
