I am getting warning as \"[Accessibility] Missing contentDescription attribute on image\" for imageview. while using android lint
What does that mean?
I recommend you to add the contentDescription.
android:contentDescription="@string/contentDescriptionXxxx"
but, let's be realistic. Most people don't maintain literal for accessibility. Still, with little effort, you can implement something to help people with disability.
deco
button de action
image with data
image from an other user
.
The most important thing the blind user will need to know is "Where is the button that I need to click to continue"
Use contentDescriptionAction for anything clickable.
use contentDescriptionContent for image with information (graph, textAsImage, ...)
use contentDescriptionUserContent for all user provided content.
use contentDescriptionUseless for all the rest.
