Error: 'color' attribute should be defined

A color selector is defined as following:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true">
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">
            <solid android:color="@color/gray" />

        </shape>
    </item>
    <item android:state_focused="true">
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">
            <solid android:color="#66666666" />

        </shape>
    </item>
    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">
            <solid android:color="@color/translucent_icon_background" />
        </shape>
    </item>
</selector>

In Android Studio, 'item" is marked red indicating an error as shown by the following screenshot: enter image description here

The app works fine per tests. I am asking because I am afraid it may not be fine on some devices due to that error. Could anyone shed some light on this error? More specifically, can it be ignored?

You need to create the 'selector.xml' in the 'drawable/' folder rather than 'color/' folder.enter image description here

I had the same error and I removed it by adding a color attribute with the item tag.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#ffffff">  <--**add this** 
    <shape
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="oval">
        <solid android:color="@color/gray" />

    </shape>
</item>
<item android:state_focused="true" android:color="#ffffff"> **<--add this** 
    <shape
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="oval">
        <solid android:color="#66666666" />

    </shape>
</item>
<item android:color="#ffffff">   **<--add this** 
    <shape
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="oval">
        <solid android:color="@color/translucent_icon_background" />
    </shape>
</item>

Good luck.
