According to Android accessibility guidelines, what attribute must interactive UI elements provide for TalkBack screen reader compatibility?
Answer: android:contentDescription
contentDescription provides the text that TalkBack reads aloud when a user focuses on a non-text UI element.
A team argues that accessibility features are low priority because they benefit only a small minority of users. Which response best counters this ethically?
Answer: Accessibility improvements benefit all users, including those with temporary injuries or situational limitations like bright sunlight
Inclusive design recognizes that accessibility features, such as larger touch targets and captions, improve usability for everyone.
What minimum color contrast ratio does WCAG 2.1 AA standard require for normal-sized body text?
Answer: 4.5:1
WCAG 2.1 AA requires at least a 4.5:1 contrast ratio for normal text to ensure readability for users with low vision.
An app communicates all error states exclusively through color (red = error, green = success). Why is this an accessibility violation?
Answer: It excludes users with color vision deficiencies who cannot reliably distinguish red from green
Approximately 8% of men have red-green color blindness; WCAG requires that information not be conveyed by color alone.
According to Material Design guidelines, what is the recommended minimum touch target size for interactive elements?
Answer: 48x48 dp
A 48x48 dp minimum touch target ensures users with motor impairments or large fingers can reliably activate controls.
What ethical consideration should guide developers when choosing the minSdkVersion for their Android app?
Answer: Recognize that users in underserved markets disproportionately rely on older devices and weigh their exclusion carefully
Setting a very high minSdkVersion can exclude users in lower-income regions where older devices are more common, raising equity concerns.
Which practice demonstrates ethical inclusive design for users who rely on Android's font size accessibility settings?
Answer: Using sp (scale-independent pixels) for text sizes so they respond to the user's font scale preference
Using sp units ensures text scales with the user's system font size setting, which is critical for users with low vision.
