    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

    Linux Deploy

    Linux Deploy

    Install and run GNU/Linux on Android

    This application is open source software for quick and easy installation of the operating system (OS) GNU/Linux on your Android device. The application creates a disk image or a directory on a flash card or uses a partition or RAM, mounts it and installs an OS distribution. Applications of the new system are run in a chroot environment and working together with the Android platform. All changes made on the device are reversible, i.e. the application and components can be removed completely. Installation of a distribution is done by downloading files from official mirrors online over the internet. The application can run better with superuser rights (root). The program supports multi language interface. You can manage the process of installing the OS, and after installation, you can start and stop services of the new system (there is support for running your scripts) through the UI. The installation process is reported as text in the main application window.

    Android Interview Questions

    Android Interview Questions

    Your Cheat Sheet For Android Interview

    This repository is a comprehensive study guide for Android interviews, organized to cover the platform from fundamentals to advanced topics. It includes explanations and Q&A on the Android app lifecycle, activities and fragments, services, broadcast receivers, content providers, and the build system. Modern practices are addressed as well—Kotlin language features, coroutines, Jetpack components, MVVM/MVI architecture, dependency injection, and testing strategies. Performance and reliability topics receive attention, such as memory management, threading, WorkManager, networking, and offline storage patterns. The content favors concise, practical answers that interviewers expect, helping candidates rehearse concepts and trade-offs rather than memorize trivia. It’s equally useful for brushing up before an interview and for leveling up day-to-day Android engineering knowledge.

    Buck

    Buck

    Build system that encourages the creation of small, reusable modules

    Buck is a build system developed and used by Facebook. It encourages the creation of small, reusable modules consisting of code and resources, and supports a variety of languages on many platforms. Buck builds independent artifacts in parallel to take advantage of multiple cores on your machine. Further, it reduces incremental build times by keeping track of unchanged modules so that the minimal set of modules is rebuilt. Buck only uses the declared inputs, which means everybody gets the same results. Buck looks at the contents of your inputs, not their timestamps to figure out what needs to be built. As a result, incremental builds should always be correct, so there's no need to perform a clean build. With buck query, you can better understand your dependencies and what is required to build your product. With buck project, your project can be better understood by your IDE, making you and your team more productive.

    fastdex

    fastdex

    Speed ​​up the compilation speed of apk

    If you can't stand the slow compilation of apk (especially if there are multiple dex in the project), fastdex can help you speed up the apk generation process. Scan all project codes and add a dependency on the fastdex.runtime.antilazyload.AntilazyLoad class in the construction method. The purpose of this is to solve the problem of class verification. For details, please refer to Android. Take a snapshot of all the dependencies of the current project, in order to compare whether the dependencies have changed when the patch is packaged in the future. If there is a change, the cache needs to be cleared. It is strongly recommended that your application do not directly depend on the library project, but make it into an aar package so that the application project can rely on it remotely.
