Building a Quiz App with SQLite in Android Studio
Quiz applications have carved out a comfortable spot in the Australian mobile market, with trivia nights still a Thursday ritual in pubs from Sydney to Perth. The local appetite for general knowledge content means apps covering AFL history, cricket stats, or capital cities tend to attract steady downloads on Google Play. Building one for yourself is a useful exercise that touches on database design, UI state management, and offline storage.
SQLite remains a sensible backbone for this kind of project because it ships with every Android device, requires no external server, and handles thousands of question rows without complaint. Before jumping into code, sketch out the flow: a list of categories, a screen of questions, a timer, and a results page. The rest is wiring.
Setting up the Android Studio project
Begin by creating an empty activity project in Android Studio, choosing a recent stable API level so the app reaches the majority of Australian handsets still in circulation. Name the package something memorable, then add the Material Components library through the Gradle dependencies block. A simple quiz app does not need many external libraries, which keeps the APK small enough for users on regional 4G networks in places like Cairns or Hobart.
Make sure the manifest declares the main activity as the launcher and that the application theme inherits from a Material theme rather than the default. If you plan to ship images for each question, create an assets folder now and drop a placeholder PNG inside so you can verify paths later when wiring up the image loader.
Designing the SQLite database schema
A quiz app needs at least two tables: one for questions and one for tracking attempts. The question metadata table typically stores an id, the prompt text, the correct answer, the three wrong answers, the category, and the difficulty. The attempts table can hold a timestamp, the score, the total questions, and the category the player chose.
Decide on the columns carefully because once an app ships a database schema, changing it later requires migration code that many first-time developers underestimate. A common rookie mistake is storing the four answer choices as a single comma-separated string, which makes validation painful when the user taps one of them. Store each choice in its own column so a correct answer check is a simple equality test.
Building the data model and database helper
Create a Question POJO that mirrors the schema, with primitive fields for the id and difficulty, a String for the prompt, and an array or list for the choices. Then write a SQLiteOpenHelper subclass that handles the onCreate and onUpgrade callbacks. Keep the helper methods small and focused: one to insert sample questions, one to fetch a random batch by category, and one to wipe the attempts table when the user clears local history.
Reading rows in random order is a small detail that matters for replay value. Players in Melbourne who run through the same trivia set twice in a week will quickly memorise the answer order if you always return rows sorted by id. Use ORDER BY RANDOM() and LIMIT on the query so each session feels fresh.
| Storage layer | Best for quiz apps | Offline capable | Migration burden |
|---|---|---|---|
| SQLite | Large question banks, history, statistics | Yes | Medium |
| Room | Same as SQLite with type-safe queries | Yes | Low |
| SharedPreferences | Last played category only | Yes | Low |
| Remote API | Always-fresh questions, leaderboards | No | High |
Start with SQLite so you understand the raw query language, then migrate to Room once the schema stabilises. Both options keep the app fully functional on a flight from Brisbane to Darwin without an internet connection, which matters for travellers and commuters who spend long stretches away from Wi-Fi.
Wiring up the quiz activity layout
The quiz screen needs a question prompt area, four answer buttons arranged in a vertical LinearLayout or a ConstraintLayout chain, a progress indicator, and a timer text view. Australian designers often favour generous padding and darker accent colours that match common sports team palettes, but the layout itself should follow Material guidelines so screen readers behave predictably across the wide range of devices sold locally.
Hook the layout into an activity that holds a list of Question items loaded from the database on a background thread. Display the first question immediately while the timer counts down from fifteen seconds. When a button is tapped, disable all four choices, flash a green or red colour, and advance to the next question after a short delay so the user can register the outcome.
Adding the timer and scoring logic
A countdown timer can be a simple CountDownTimer object that ticks every second and posts updates to the text view. When the timer reaches zero, treat the question as skipped and record a zero score for that item. Keeping the score in an integer field inside the activity works for a single round, but if the user replays multiple times, consider persisting each session.
Avoid the temptation to store the running score inside the database during play. Frequent writes from the UI thread cause jank, and quiz sessions are short enough that an in-memory accumulator plus a single commit at the end is more than adequate. This is a habit worth picking up early if you ever graduate to multi-table financial apps or inventory tools that Australian retailers use in store.
Loading question images with Glide
If your trivia set includes picture rounds, the Glide library handles caching and asynchronous loading without much fuss. You can fetch remote images into an ImageView by passing a URL into the Glide.with(context).load(url).into(imageView) chain, and the library will manage the cache so users on Australian mobile plans are not punished with repeated downloads during a long trivia session.
For self-hosted assets, drop the files into the assets folder and reference them with a file:///android_asset/ prefix. The technique for loading remote images covers both scenarios in detail, and is worth bookmarking for future projects that involve user avatars or promotional banners across multiple activities.
Persisting results and reviewing performance
When the quiz finishes, write a row to the attempts table containing the timestamp, the score, the total, and the category. A simple results screen can then query the top five scores by category and display them in a RecyclerView. Players enjoy seeing whether they beat their last attempt, especially when the category is something niche like Australian geography or rugby league.
If you want to share the scoreboard later, exporting to CSV is straightforward and lets users open the file in Google Sheets on their phones. The full source code for a working sample is available on own GitHub repository, where the project also includes a list of capital cities and state emblems for the geography round.
