Perform Accessibility Testing in Android

In Android development, accessibility testing ensures apps work for users with disabilities and comply with standards like WCAG and ADA for usability and legal requirements.

Read this article to know why accessibility testing is important in Android, the core concepts, tools, and the step by step process to perform both manual and automated accessibility testing effectively.

Why Accessibility Testing in Android is Essential?

Here are some of the reasons mentioned for the importance of accessibility testing in Android:

• Ensures people with visual, auditory, motor, or cognitive impairments can use your app easily.
• Helps meet WCAG, ADA, and Section 508 standards to avoid legal risks.
• Improves navigation, readability, and usability for all users, not just those with disabilities.
• Builds brand reputation, reduces lawsuits, and gives preference in the accessibility first markets.

Core Concepts of Accessibility Testing for Android

Here are the core concepts of accessibility testing required for Android to make it compatible for people with disabilities:

• Text Alternatives: Every non-text element (icons, images, buttons) should include meaningful content descriptions for screen readers.
• Color Contrast: Text and interactive elements must meet minimum contrast ratios (4.5:1) to remain visible for users with low vision.
• Touch Target Size: Buttons and tap areas should be at least 48 x 48dp (44 x 44px) to ensure ease of use without accidental taps.
• Screen Reader Compatibility: Apps should work perfectly with TalkBack on Android, and correct detailing of all UI elements.
• Accessible Labels: Form inputs, controls, and buttons should have descriptive, accessible labels for clarity.
• Dynamic Content Announcements: Pop ups, alerts, and live updates should be communicated to assistive technologies in real time.
• Keyboard & Switch Input Support: Users should be able to operate the app fully with hardware keyboards, voice commands, or switch devices.

Key Accessibility Guidelines for Android Apps

Some of the important accessibility guidelines to be followed for Android apps are:

• WCAG (Web Content Accessibility Guidelines): A global standard that defines principles like perceivable, operable, understandable, and robust, for apps to meet accessibility needs across devices.
• ADA (Americans with Disabilities Act): A US regulation that requires digital products, including mobile apps, to provide equal access to people with disabilities.
• Section 508: A US federal law mandating that all electronic and information technology used by government agencies must be accessible to people with disabilities.

How to Perform Accessibility Testing in Android?

By combining manual validation with screen readers and automated scans through frameworks or cloud platforms like BrowserStack, teams can detect compliance issues early.

Performing Manual Accessibility Testing in Android

With BrowserStack App Accessibility, a user can run these tests directly on real Android devices in the cloud, ensuring accuracy across different manufacturers, screen sizes, and OS versions. Here are the steps to be followed for manual accessibility testing:

Step 1: Log in to BrowserStack account and select the App Accessibility section. This is where the manual accessibility testing begins on Android.

Step 2: Select an Android device from BrowserStack’s real device cloud. Upload your APK/AAB or provide a Play Store link to launch the app.

Step 3: Start a new session to open the App Workflow Analyzer, which automatically scans app screens once interaction is started.

Step 4: Set the compliance level (WCAG and ADA standards) and allow for all usability checks. Then manually use the app while the analyse detects accessibility issues in real time.

Step 5: See all the issues categorised by severity and guidelines violated. Detailed explanations, screenshots, and solutions help your team fix problems faster.

Step 6: Once the report is prepared, export it and share with the team or directly push it into tools like Jira or Azure DevOps for tracking.

Automating Accessibility Testing in Android

Here are the steps to be followed for automated accessibility testing in Android on the BrowserStack platform:

Step 1: Log in to BrowserStack and access the App Accessibility Testing feature. Once the account is configured for automation with necessary permissions and integrations.

Step 2: Upload the APK/AAB file to the BrowserStack App Live & Automate dashboard, or provide a Play Store URL. This allows the platform to prepare an app for automated accessibility scans.

Step 3: Select the Android devices, OS versions, and screen sizes to run automated tests. This ensures coverage across real user environments.

Step 4: Activate BrowserStack’s Spectra AI engine, which runs WCAG and usability checks automatically during the test sessions.

Step 5: Run accessibility tests using BrowserStack’s automation framework support (Appium, Espresso, or XCUI). As the app flows are executed, the engine continuously scans for accessibility issues.

Step 6: Once the testing is complete, review automatically generated accessibility reports. These include issues by severity, WCAG violations, screenshots, and remediation suggestions.

Step 7: Connect BrowserStack with tools like Jenkins, GitHub Actions, Jira, or Azure DevOps to push results into the CI/CD pipeline and log issues directly for developer action.

Common Challenges in Accessibility Testing for Android

Some of the major challenges in accessibility testing in Android are:

• Android apps must be tested across multiple devices, screen sizes, and OS versions, making accessibility validation complex.
• Tools like TalkBack may behave differently on various devices, leading to inconsistent results.
• Custom views, animations, and other UI components may fail accessibility checks if not coded with proper semantics.
• Verifying accessibility with screen readers and touch navigation is time consuming and can have errors too.
• Automated scans can’t always detect context specific issues like logical focus order or meaningful alt text.

Best Practices for Effective Accessibility Testing in Android

Some of the best practices to be followed by every team for effective accessibility testing in Android are:

• Do accessibility testing from the design and coding stages, so that UI components, colors, and labels meet WCAG and ADA standards before QA.
• Check accessibility on real Android devices to understand real world behavior of TalkBack, gestures, and dynamic layouts.
• Use automated scans for quick detection of issues, but try to have manual checks for context based issues like focus order and content meaning.
• Actively test with screen readers, switch access, and voice commands to analyse real user experiences with disabilities.
• Automate accessibility testing with tools like BrowserStack to continuously validate compliance and prevent regressions in each release.
