'Missing contentDescription attribute on image' in XML

Question

I get an warning about [Accessibility]Missing contentDescription attribute on image in eclipse. This warning show at line 5 (declare ImageView)

Answer 1

Updated:

As pointed out in the comments, setting the description to null indicates that the image is purely decorative and is understood as that by screen readers like TalkBack.

Old answer, I no longer support this answer:

For all the people looking how to avoid the warning:

I don't think android:contentDescription="@null" is the best solution.

I'm using tools:ignore="ContentDescription" that is what is meant to be.

Make sure you include xmlns:tools="http://schemas.android.com/tools" in your root layout.
