Accessibility: Missing labels on Main Screen controls and other fixes

[AnaFerreira015]

Hi! I’m Ana Ferreira, a Master's student in Computer Science.

As part of my research on mobile accessibility, I am analyzing open-source Android applications to help identify and correct accessibility barriers so users can utilize assistive technologies (like TalkBack) more effectively.

I’ve been exploring Countdown Timer and found a specific issue on the Main Screen, so I wanted to propose a fix.

1. The Issue

On the Main Screen, the Select Time Seconds component presents the following behavior:

• Current behavior: The element lacks a descriptive text label. TalkBack announces it simply as "Unlabelled" (or "Button"), violating WCAG 4.1.2 (Name, Role, Value).
• Impact: Users relying on screen readers cannot distinguish this control from others or understand its function immediately.

2. Proposed Solution

To fix this, I suggest adding an android:contentDescription to the element in the XML layout.

Code snippet / XML suggestion:

<ImageButton
    ...
    android:contentDescription="@string/action_add_timer" />

3. Additional fixes (Need your input)

I have identified 3 other categories of accessibility improvements for the Countdown Timer.

To avoid spamming your notification feed, how would you prefer I submit these?

• Option A: List them all here in this issue (I can update the comment below).
• Option B: Open separate issues for each specific problem.

I can provide detailed fixes for these upon request.

Please let me know your preference, and I will proceed accordingly.

Best regards,
