Considerations like larger touch targets can greatly enhance usability for individuals with motor impairments. It’s about surpassing the basics and integrating visual cues that assist users in comprehending the functions of various elements.

The PSPDFKit for Android 6 is a perfect example of this. The PSPDFKit team realized that their primary UI, PDFActivity, was difficult to operate with just a keyboard. Numerous focusable elements were invisible to the user, and focus often shifted between unrelated elements. To address these issues and enhance keyboard navigation, they utilized the Android emulator and TalkBack. They also modified the ViewGroup.focusSearch method to ensure a consistent and controlled focus movement throughout the UI.

The Android platform also offers libraries like Jetpack and Compose that aid in building accessible apps. Android provides guidelines to make apps more user-friendly for individuals with disabilities, such as requiring UI elements to have a focusable area or touch target size of at least 48dp x 48dp. Each UI element should also have a description using the contentDescription attribute.

For text visibility, color contrast ratios are recommended based on the font size and boldness. This is crucial to ensure readability for all users. Moreover, using string resources for easier localization can significantly improve accessibility.

Improving text visibility in mobile apps is a key factor in offering a user-friendly experience. Here are some best practices:

  • Font Size: A minimum font size of 16px is recommended to ensure readability on smaller screens.
  • Contrast: High contrast between the text color and the background color enhances readability. Light text on a light background or dark text on a dark background should be avoided.
  • Text Alignment: Depending on the language and reading habits of your target audience, align the text to the left or center. This facilitates easy scanning and reading.
  • Line Height: An appropriate line height prevents text from appearing cramped or overcrowded. A line height of 1.5 times the font size is generally recommended.
  • Font Style: Choose a font that is legible and clear, even at smaller sizes. Sans-serif fonts are often preferred for mobile apps due to their clean and modern look.
  • Avoid Text Overlays: Placing text directly on top of images or complex backgrounds can make the text hard to read. Use text containers or clear areas for text placement instead.
