The KUKSA Companion App demonstrates the capabilities of the Android SDK to connect to a vehicle with an integrated KUKSA Databroker, read data and interact with the actuators of the vehicle. The KUKSA framework is based on the COVESA Vehicle Signal Specification (VSS). The VSS defines the names and semantics of a large set of data entries that represent the current and/or intended state of a vehicle's sensors and actuators organized in a tree-like structure. For example, the vehicle's current speed is represented by the Vehicle.Speed entry. However, VSS does not define how these signals are to be collected and managed within a vehicle, nor does it prescribe how other components in the vehicle can read or write signal values from and to the tree. The KUKSA Databroker is a resource efficient implementation of the VSS signal tree and is intended to be run within a vehicle on a microprocessor based platform. It allows applications in the vehicle to interact with the vehicle's sensors and actuators using a uniform, high level gRPC API for querying signals, updating current and target values of sensors and actuators and getting notified about changes to signals of interest. Showcases covered by the Companion App are: - Door Control - Temperature Control - Light Control - Tire Pressure Check Find out more about KUKSA: - Vehicle Signal Specification: https://covesa.github.io/vehicle_signal_specification/ - KUKSA Databroker: https://github.com/eclipse/kuksa.val/ - KUKSA Android SDK: https://github.com/eclipse-kuksa/kuksa-android-sdk/ - KUKSA Companion App: https://github.com/eclipse-kuksa/kuksa-android-companion/

Kaku is a fast, powerful Japanese dictionary that stays on top of all your apps. It uses optical character recognition (OCR) technology to recognize kanji on the device screen for you (rather than the slowww tedious process of looking up individual characters manually), making it perfect for Japanese learners who want to study by reading raw manga, play untranslated games, and so on without the hassle of switching apps.

Kakugo is an application that helps learning Japanese. It includes multiple tests to memorize hiragana, katakana, and kanji and adapts to the user's learning pace. One of the biggest difficulty with learning Japanese is memorizing kanji and vocabulary. While learning them by just reading and writing them everyday may work, the more kanji you know, the harder it gets and the more time it takes to revise them all. Proper tools can help you memorize these huge amounts of knowledge to more quickly become a fluent Japanese speaker. Kakugo is one of these tools. It helps learning and revising kanji and vocabulary in an efficient manner. It uses Spaced Repetition in a unique way that adapts to the user's pace. If you only have time to revise 30 kanji every day, or if you can revise as much as 100 kanji every day, Kakugo will adapt and test you on the right kanji at the right time for you to memorize them. There is no "kanji of the day" list to revise, you can start and finish a session whenever you feel like it. Kakugo also features a wide variety of tests to help you find the best ways that will help you learn Japanese. Features include * Hiragana, Katakana quizzes * Kanji quizzes by reading and meaning * Kanji test by part composition * Kanji writing test * Vocabulary quizzes by reading and meaning * Unique spaced repetition formula that adapts to your own learning pace * Unlimited quiz sessions that allow you to take a quiz at any time, for however long you want, useful to efficiently spend commuting time * Show similar-looking kanji in answers to teach you the differences * Kanji and vocabulary sorted by JLPT level * Clicking on kanji opens aedict3 (a non-free Japanese dictionary) or jisho.org * Optimized tablet support * Open source * No ads * No internet access required * Supported languages: English, French * More to come Credits * The kanji quizzes are based on kanjidic. * The vocabulary quizzes are based on JMdict. * The kanji similarity database comes from https://minerva-access.unimelb.edu.au/handle/11343/35336 and http://lars.yencken.org/datasets/phd/ * The kanji composition and drawing database comes from KanjiVG.

Kanade is a simple app that allows you to extract apk from your apps list. Fully open-source and zero-ads.

A simple application that lets you draw Japanese characters (kanji) using the touch screen. It is intended for Japanese language learners who might need to enter characters in order to look them up in a dictionary or enter them on a website. It identifies the character you have drawn using a special form of handwriting recognition. You can select the correct character from a list. After entering one or more characters, you can copy them into the clipboard as text for use in a dictionary. Note that this will NOT work - at all - if you don't know basically how to draw kanji. If you just draw something any old way that looks like it, it certainly won't be recognised. You have to draw characters basically the official way. This is a fork of the Kanji draw application from https://github.com/quen/kanjirecog/ which is no longer maintained and was removed from F-Droid. Two of the included icons were taken from the Android SDK and are licensed under the Apache License 2.0. The kanji stroke data is based on the KanjiVG data set from http://kanjivg.tagaini.net/ and licensed under the Creative Commons Attribution-Share Alike 3.0 license.
