Add android contentDescription   string description   static or dynamic  to  your ImageView   Please do not ignore nor filter the message  because it is helpfull for people using alternative input methods because of their disability  Like TalkBack  Tecla Access Shield etc etc

Follow this link for solution  Android Lint contentDescription warning  Resolved this warning by setting attribute android contentDescription for my ImageView android contentDescription  quot  string desc quot  Android Lint support in ADT 16 throws this warning to ensure that image widgets provide a contentDescription This defines text that briefly describes the content of the view  This property is used primarily for accessibility  Since some views do not have textual representation this attribute can be used for providing such  Non-textual widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface   This link for explanation  Accessibility  It s Impact and Development Resources  Many Android users have disabilities that require them to interact with their Android devices in different ways  These include users who have visual  physical or age-related disabilities that prevent them from fully seeing or using a touchscreen  Android provides accessibility features and services for helping these users navigate their devices more easily  including text-to-speech  haptic feedback  trackball and D-pad navigation that augments their experience  Android application developers can take advantage of these services to make their applications more accessible and also build their own accessibility services   This guide is for making your app accessible  Making Apps More Accessible  Making sure your application is accessible to all users is relatively easy  particularly when you use framework-provided user interface components  If you only use these standard components for your application  there are just a few steps required to ensure your application is accessible   Label your ImageButton  ImageView  EditText  CheckBox and other user interface controls using the android contentDescription attribute   Make all of your user interface elements accessible with a directional controller  such as a trackball or D-pad   Test your application by turning on accessibility services like TalkBack and Explore by Touch  and try using your application using only directional controls

If you don t care at all do this       android contentDescription   null    Although I would advise the accepted solutions  this is a hack  D

It is giving you the warning because the image description is not defined  We can resolve this warning by adding this code below in Strings xml and activity main xml Add this line below in Strings xml  lt string name  quot imgDescription quot  gt Background Picture lt  string gt  you image will be like that   lt ImageView         android id  quot   id imageView2 quot          android lay enter code hereout width  quot 0dp quot          android layout height  quot wrap content quot          android contentDescription  quot  string imgDescription quot          app layout editor absoluteX  quot 0dp quot          app layout editor absoluteY  quot 0dp quot          app srcCompat  quot  drawable background1 quot          tools layout editor absoluteX  quot 0dp quot          tools layout editor absoluteY  quot 0dp quot    gt   Also add this line in activity main xml android contentDescription  quot  string imgDescription quot   Strings xml  lt resources gt       lt string name  quot app name quot  gt Saini Browser lt  string gt       lt string name  quot SainiBrowser quot  gt textView2 lt  string gt       lt string name  quot imgDescription quot  gt BackGround Picture lt  string gt   lt  resources gt

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

This warning tries to improve accessibility of your application   To disable missing content description warning in the whole project  you can add this to your application module build gradle  android                 lintOptions           disable  ContentDescription

Going forward  for graphical elements that are purely decorative  the best solution is to use   android importantForAccessibility  no    This makes sense if your min SDK version is at least 16  since devices running lower versions will ignore this attribute   If you re stuck supporting older versions  you should use  like others pointed out already    android contentDescription   null    Source  https   developer android com guide topics ui accessibility apps label-elements

The warning is indeed annoying and in many  most   cases no contentDescription is necessary for various decorative ImageViews   The most radical way to solve the problem is just to tell the Lint to ignore this check   In Eclipse  go to  Android Lint Error Checking  in Preferences  find  contentDescription   it is in the  Accessibility  group  and change  Severity   to Ignore
