Android Lint contentDescription warning

Question

I am getting warning as \"[Accessibility] Missing contentDescription attribute on image\" for imageview. while using android lint

What does that mean?

Answer 1

For graphical elements that are purely decorative, set their respective android:contentDescription XML attributes to "@null".

If your app only supports devices running Android 4.1 (API level 16) or higher, you can instead set these elements' android:importantForAccessibility XML attributes to "no"
