Missing contentDescription attribute on ImageView in XML - Android

I've the below ImageView in my XML file,

<ImageView  

            android:layout_width="wrap_content" 

            android:layout_height="wrap_content"

            android:id="@+id/myImgView"

            android:src="@drawable/something"/>

I get a warning saying that [Accessibility]Missing contentDescription attribute on image in Eclipse IDE. Since it is a warning we used to ignore it.. However to overcome this warning, all you need to add is the below piece of code in ImageView,

android:contentDescription="@string/description" (static or dynamic) 

This is helpful for people using alternative input methods because of their disability (like TalkBack, Tecla Access Shield etc)
