Introduction 👋 This is an app created as a demo of some Android features. The main purpose of the app is to provide a random choice in different ways. The app contains some basic personalization options and an introduction, plus some new resources like animated vector drawables and the full light theme. The design is a bit personal: it follows the Android guidelines, but just partially. Why should i use Randomix? 😕 Well, i'll tell you 3 main reasons: It can help you to decide randomly in 4 different ways, elegantly! It will cost just 3MB of storage! It's beautiful, full of animations and simple to use! An example? → During a table game, you have to throw a dice, a coin, or choose which player should start: Randomix does it all! → You're hungry but you and your friends can't decide a place to have a meal: just spin the roulette and accept its wise answer! → You're starting to develop apps and you need a simple app to look at, to find some inspiration and tricks: click on the Github link, and the Randomix source code is served! Features 🎲 Every tab in the bottom navigation bar contains a type of random choice. The available types are: Roulette → select an option from a list. Coin → simply flips a coin and prints the result. Dice → throws a dice and prints the result. Magic Ball → provides randomly chosen answers to any question. The recent options used in the roulette are automatically saved and can be restored! Roulette presets, such as 1-100 numbers and letters Shake to launch option Light, dark and Amoled themes, Material You Up to 10 dice and different dice types, plus a 3v3 mode Selectable accent Android 13 per-app language and themed icon support Vibration and sounds Rude answers, allow equal options, dice number First time introduction Multiwindows support Simple and precise ui following the material guidelines Credits ⚡ This app was written during my free time as a training. Many good devs have helped me understanding the best practices. Thanks to BValeo for the russian translation, and to Firokat for the french translation. And a special thanks to Stack Overflow, obviously.

Do you keep lists of your favorite things, such as movies, books, recipes, or music albums? You might keep list(s) that looks like this: Network (1976) Lone Star (1996) Devils (1971) The Seventh Seal (1957) ... Many more films_h But how do you rank these? You might be tempted to order them by preference, but this could quickly get overwhelming for long lists. A much easier method is to use pairwise comparisons, which shows you single head-to-head pairs, and has you choose which one you like best. After doing a small number of these matchups, Rank-My-Favs can confidently create a ranked list for you. Under the hood, Rank-My-Favs can sort by either the win-rate, or the more advanced Glicko rating system.

Try and find a regular expression (Perl style) to match certain strings, while not matching others. Currently there are three game modes, that can be selected and configured from the settings. These generate Tasks, set limits to how many characters may be used, and which solutions are successful an which are not. All game modes are based on the same concept: the Task to solve will be displayed on the screen as soon as possible (near immediately for Random game, longer for REDB game), and then the user has to enter a regular expression to solve the task. As soon as it fits to conditions, it will be automatically submitted, and the next task will generate - no questions asked. The user will be notified in case s?he rises up a level.
