I get an warning about [Accessibility]Missing contentDescription attribute on image in eclipse. This warning show at line 5 (declare
<?xml version="1.0" encoding="utf-8"?>
I thinks follow this link for solution: Android Lint contentDescription warning
Resolved this warning by setting attribute android:contentDescription for my ImageView
Android Lint support in ADT 16 throws this warning to ensure that image widgets provide a contentDescription
This defines text that briefly describes 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.

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 augment their experience. Android application developers can take advantage of these services to make their applications more accessible and also build their own accessibility services.
and this guide is for making your app accessible: http://developer.android.com/guide/topics/ui/accessibility/apps.html
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.
