Chapter 19 Accessibility
For the More Curious: Using Accessibility Scanner
In this chapter you focused on making your app more accessible to people using TalkBack. But this is
not the whole story. Accommodating visual impairments is just one subset of accessibility.
Testing your application for accessibility should really involve user tests by people who actually use
accessibility services on a regular basis. But even if this is not possible, you should still do your best to
make your app accessible.
Google’s Accessibility Scanner analyzes apps and evaluates how accessible they are. It provides
suggestions based on its findings. Try it out on CriminalIntent.
Begin by following the simple instructions at play.google.com/store/apps/details?
id=com.google.android.apps.accessibility.auditor to install the app on your device.
Once you have Accessibility Scanner installed and running and you see the blue check mark icon
hovering over your screen, the real fun can begin. Launch CriminalIntent from the app launcher
screen or overview screen, leaving the check mark alone. Once CriminalIntent appears, make sure it is
displaying the crime details screen (Figure 19.11).
