Get started with Accessibility Scanner

When you design and develop an Android app, Accessibility Scanner can help you identify opportunities to improve your app for users.

Accessibility Scanner scans your screen and provides suggestions to improve the accessibility of your app, based on the following:

  • Content labels
  • Touch target size
  • Clickable items
  • Text and image contrast

Note: Accessibility Scanner isn't a replacement for manual testing and doesn't guarantee an app's accessibility.

Step 1: Install and turn on Accessibility Scanner

Accessibility Scanner is available for phones and tablets with Android 6.0 and above. See what version of Android you have.

To start, download Accessibility Scanner from Google Play.

When you open Accessibility Scanner, you're prompted to turn it on in your device settings:

  1. Go to Settings and then Accessibility and find Accessibility Scanner.
  2. Tap the Accessibility Scanner switch to move it to the on position.

You can turn off the Accessibility Scanner any time by returning to Settings and then Accessibility and then Accessibility Scanner.

Step 2: Scan your app

To scan your app, follow these steps:

  1. Open your app.
  2. Tap the Accessibility Scanner button .
  3. You'll see a screenshot of the app with notes about possible improvements. To get a full list of results, tap the List .

Notes:

  • If you're using TalkBack, explore by touch to reach the Accessibility Scanner button.
  • If you see a black screen after scanning your app, this means it's a secure window. If a window is declared "secure" using WindowManager.LayoutParams.FLAG_SECURE (usually in apps dealing with financial or personal information), Accessibility Scanner can't capture an image of that screen or assess color contrast. However, you can still review the scan results for other opportunities.

Customize Scanner settings

You can adjust the thresholds that Scanner uses for contrast ratio and touch target size.

  1. At the bottom of your screen, tap Home Home.
  2. On Pixel phones, swipe up from the bottom of your screen. On other devices, tap All Apps Apps menu.
  3. Tap Scanner Accessibility Scanner.
  4. Tap Settings Settings.

On the Scanner settings screen, you can change the following:

  • Contrast ratio: Set a new minimum threshold for text and image contrast.
  • Touch target size: Set a new minimum threshold for touch target size.

You can share complete results or an individual item with other people, such as teammates. To share results, follow these steps:

  1. After scanning your app, tap Share .
  2. Choose how you want to share the zip file with the results and screenshots.

Note: To share results for an individual item, tap Share while viewing the item.
