While tools like Accessibility Scanner can help you make some significant improvements to your app's accessibility, these tools are no replacement for manual testing.

Accessibility needs to be approached holistically— Accessibility Scanner , for example, will tell you if you're missing a label, but cannot tell whether that label makes sense. Generally, Accessibility Scanner cannot determine whether your user interface conveys semantic information simply and clearly.

In addition, Accessibility Scanner cannot report on how well an app supports multiple modes of interaction touch vs. But Accessibility Scanner provides an introduction to accessibility, and it's an invaluable accessibility tool that you should consider using often.

Audience and Prerequisites This codelab is intended for Android developers who want to understand how to make their apps accessible to users with accessibility needs. This codelab assumes the following: Basic familiarity with writing Android apps.

Getting Set Up What you'll be building In this codelab, you'll be working with an existing app, Counter. Download the Code You can get the source code for the starting version of the app from GitHub. Launching the demo application Launch Android Studio and open the Counter project. Make sure a device is connected to your computer. Press the green Play icon from the menu bar towards the top of the screen. This should launch the Counter app. Accessibility Scanner Accessibility Scanner is a tool created by Google that suggests accessibility improvements for Android apps—such as enlarging small touch targets, increasing contrast, and providing content descriptions—so that individuals with accessibility needs can use your app more easily.

Return to the Counter app. Your screen should now look like this: You'll notice that Accessibility Scanner creates a blue Floating Action Button FAB , which is overlayed on top of any content you have on the screen.

Scanning the Counter App In this section you'll perform an accessibility audit of the screen using Accessibility Scanner : Tap on to launch the scan.

Examine the output from running a scan. It should look something like this: Accessibility Scanner highlights the views that may have accessibility issues, and offers suggestions for how you can fix those issues.

Voice support is what those who are completely blind will use, while the other one letter expansion is for those who need letters zoomed bigger as they use their device.

Here, you would disable talkback and press your home button three times in quick succession to enable the service.

If you are using a Galaxy device however, simply disable talkback in Accessibility settings and press the home button three times. The screen reader offers some functionality not present in Talkback. For example, you can copy the screen to the clipboard, or parts of text. There are two interesting ones called Ear Talk and whisper. Ear Talk will redirect all speech to this speaker entirely, so in theory it could be used in situations where you are looking for privacy but do not have headphones.

In practice, it is a bit tricky to use as a touch screen element can easily be activated. To access the command pannel, swipe right than left in quick succession. Test with the latest version available. TalkBack screen reader for Android comes already installed on some devices. It's recommended to use a shortcut to turn TalkBack on or off. If you are new to TalkBack, you may find the rate in which announcements are made too quick to understand.

To find a speech rate that you are comfortable with:. When testing with assistive technology it's important to test with content in a language that you can understand and with a language that is supported by the assistive technology.

For further information see the assistive technology testing in a foreign language guide. TalkBack language support varies by device , check what languages are supported on your device. Following the same steps every time , ensures that everyone is testing using the same methods and using the most common techniques.
