res/color/filename.xml resource file not found on real android device

Issue

In an android project a custom color resource file created to change the background color of disabled button. Added a resource file /res/color/app_color.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorDisabled" android:state_enabled="false" />
    <item android:color="@color/colorPrimary"  />
</selector>

Used this resource in style /res/valus/styles.xml

<style name="Button" parent="TextFont">
    <item name="android:background">@color/app_color</item>
    <item name="android:layout_width">370dp</item>
    <item name="android:layout_height">40dp</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">14sp</item>
    <item name="android:textColor">@color/white</item>
</style>

Used the style in a layout like below:

        <Button
            android:id="@+id/button"
            style="@style/Button"
            android:layout_width="392dp"
            android:text="@string/withdraw_in_cash"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/editText" />

This code is working fine with simulated Nexus 5X API 29x86, but for the real device (moto e 6s) it crashes with an error like a blow:

Solution

Change your app_color.xml file from this

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorDisabled" android:state_enabled="false" />
    <item android:color="@color/colorPrimary"  />
</selector>

To this

 <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@color/colorDisabled" android:state_enabled="false" />
        <item android:drawable="@color/colorPrimary"  />
    </selector>

You are supposed to use drawable not color

Hope you got a difference...
