🎭 Scenario

You’re halfway through your morning coffee when your brain reminds you: “We agreed to learn one new word a day, remember?” But dictionaries are long. Flashcards are lost. And your cat sat on your notes. Thankfully, a genius idea hits: a minimalist app that serves one word and its meaning daily, spoken aloud so even your half-asleep self can absorb it. Sounds great, right?

Yeah, well… now you have to build it—time to ship that Word of the Day screen.

🎯 Feature Goal

Create a single-screen “Word of the Day” experience that displays a randomly selected word and definition in a clean, focused card layout, with a one-tap button to hear both read aloud via Text-to-Speech.

📌 Requirements

ℹ️ You can find a downloadable PDF with the complete requirements in the Resources section👉🏼

• On launch, pick one of the words with its definition to show in the UI

  • You can find all words with their definitions in the Resources section👉🏼

• Vertical gradient background that consists of three (3) colors

  • The gradient must be edge-to-edge (i.e. it must render underneath the system bars)

• Centered content

  • Card component with a title and description text

  • An icon button below the card containing a volume icon

• When the button is tapped, the title and description text need to be read aloud (not by you but by the device!).

🤔 What's Allowed?

• Standard Android/Jetpack libraries

• No 3rd party libraries are allowed or would be required to complete this challenge

🧠 Disclaimer

• This challenge tests your “wordsmanship” in Compose layouting, styling, and TTS basics—no definition dodging allowed!

🎭 Scenario

You’re cramming for an exam with 20 tabs open, a study list somewhere in there, and brain cells slowly melting. You try to find that one topic on “clouds,” but your scroll finger files a complaint. Enough is enough. It’s time for a filtered, focused study list that listens as you type. Lucky for future-you, you’re building it now.

🎯 Feature Goal

Create a scrollable study topic list with a real-time search bar that filters items by either title or subject using a single intuitive text input.

📌 Requirements

ℹ️ You can find a downloadable PDF with the complete requirements in the Resources section👉🏼

• Title text: “Study Topics”

• Search bar underneath

  • Has a leading icon that is always visible

  • Hint text: “Search by topic or subject”

  • As the user inputs text, the list of topics should be updated

    • The logic should have a short (300 millisecond) delay before running to prevent running the logic for each character

    • The search functionality must perform a case-insensitive match against both the topic title and any of its associated subject tags. As the user types into the search bar, the list should dynamically filter to include any item where the input text matches either:

      

      • The topic title (e.g. “Skeleton” matches “The Human Skeleton”), or

      • Any of the subjects associated with that topic (e.g. “Biology” returns topics like “Photosynthesis” and “The Human Skeleton”).

    • If the input is empty, the full list should be shown. If no matches are found, display a friendly message: “No results found, try searching again!”

• The main content is a scrollable list of study topics

• Each card

  • contains a row of subjects the topic relates to (overflow goes to a second line)

  • Below is the text of the topic

  • Rounded corners

ℹ️ List of all study topics with their subject tags can be found in the Resources section 👉🏼

🤔 What's Allowed?

• Standard Android/Jetpack libraries

  • Checkout the debounce intermediary Flow operator to delay the search logic when the text input changes👀

• No 3rd party libraries are allowed or would be required to complete this challenge

⚠️ What's not important

• Perfect recreation of the mockup - it just needs to reasonably resemble the mockups

• Responsiveness across every device size or orientation is not mandatory.

🧠 Disclaimer

• This challenge is like speed dating for study topics—type a few letters, and watch them line up to impress you. Just don’t ghost your state management.

  1. A link to a Gist showing your code for this challenge.

  2. A screen recording (40s max) showcasing:

     1. Search for any topic

     2. Clear text and search for any subject

     3. Clear text and search for “Foo Empty”

     4. Show empty state

🎭 Scenario

You launch a sleek new study app and everything looks perfect—until someone tilts their phone sideways and the vertical list just… stays vertical. Awkward. Meanwhile, tablets are stuck pretending to be giant phones. Let’s face it: your feed needs to adapt. Whether users scroll or swipe, one card at a time should shine like it belongs there.

Time to make your feed smarter than gravity.

🎯 Feature Goal

Create a fullscreen, responsive feed of lesson cards that switches between vertical scrolling and horizontal paging based on device orientation and screen size, using adaptive layout techniques.

📌 Requirements

ℹ️You can find a downloadable PDF with the complete requirements in the Resources section👉🏼

• Full screen list items “feed” where each item has a background, and info block

• Full screen (edge-to-edge) background

  • The colour gradient depends on the content show. See the full list below the requirements section

• Study topic info column block

  

  • Chip with text that represents the subject the topic is related to

  • Title of the study topic. Overflow text should wrap to the next line

  • Short description of the study topic. Overflow text should wrap to the next line

  • Always placed at the bottom left corner of the screen

• Chevron icons visible at the opposite edges of the screen pointing to each edge of the scroll direction of the feed

  • Top and bottom placement: phone and tablet potrait mode

  • Start and end placement: phone and tablet in landscape mode

  • The feed should loop through the items, meaning when at the first item, the user can scroll to the last item or the 2nd item in the list

• “Swipe to see more” text

  • Always placed at the top centre of the screen

  • Only visible when the user has not scrolled for more than three (3) seconds

  • Text should have a slight fade in and out animation while visible

  • Hide the text once the user scrolls

🎭 Scenario

You open a study app, ready to find that one lesson about volcanoes… and instead, get lost in a never-ending scroll swamp. There’s no progress bar, no way to jump around, and worst of all—you just scrolled past item #49 only to realize you were looking for #3. Clearly, this isn’t just a list—it’s a battlefield. One only a brave Compose dev like you can tame. Let’s organize the chaos into a scrollable, tappable, jumpable, pinnable, and just plain usable study board.

🎯 Feature Goal

Develop a responsive and fully interactive study content board with 50+ categorized items, supporting sticky headers, pinning, index tracking, scroll-to-jump with visual highlight, and smooth scroll state preservation.

📌 Requirements

ℹ️You can find a downloadable PDF with the complete requirements in the Resources section👉🏼

  • On tap, smooth scroll the list to the heading matching the chip tapped

  • The chips are not selectable and do no have a selected state

  • Each pinned card:

    • Has a colored border to highlight it

    • On tap, navigate to the detail screen

      • After returning from the detail screen, the scroll position must remain where it was before navigating to this screen

  • Each study topic is associated with a subject. Organise the list into these subjects and add sticky headers for each subject

  • Show a FAB at the bottom right corner

    • Only visible when the first 10 items in the list are no longer visible

    • Contains an arrow pointing up icon

    • On FAB tap, smooth scroll to the top of the list so that the first list item is visible

  • Before the user reaches the end of the list, show a snackbar with text: “Reaching the end of the list!”

    • When the user only has 10 more items that need to be revealed, then show this snackbar

    • This should not be shown when the above condition is met while the list autoscrolls

Detail Screen

• Top bar

  • Back arrow icon

    • On tap navigate back to the main screen

  • Centered title text: “Course Details”
