xtensor is a C++ library meant for numerical analysis with multi-dimensional array expressions.

xtensor provides:

• an extensible expression system enabling lazy broadcasting.

• an API following the idioms of the C++ standard library.

• tools to manipulate array expressions and build upon xtensor.

Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. It provides an elegant API based on "expression templates". It is versatile: it supports all matrix sizes, all standard numeric types, various matrix decompositions and geometry features, and more.

SymEngine is a standalone fast C++ symbolic manipulation library. Optional thin wrappers allow usage of the library from other languages.

Mpfrcx is a library for the arithmetic of univariate polynomials over arbitrary precision real (mpfr) or complex (mpc) numbers, without control on the rounding. For the time being, only the few functions needed to implement the floating point approach to complex multiplication are implemented. On the other hand, these comprise asymptotically fast multiplication routines such as Toom–Cook and the FFT.

bc is an arbitrary precision numeric processing language. It includes an interactive environment for evaluating mathematical statements. Its syntax is similar to that of C, so basic usage is familiar. It also includes "dc", a reverse-polish calculator.

An rsync-like command-line utility that facilitates file transfer over ADB. There are several additional features over Google's original adbsync version with support for the --exclude, --exclude-from, --del, and --delete-excluded command line flags, which have the same purpose to the corresponding rsync flags.

This package provides a standalone port of AOSP's libsparse that converts Android sparse filesystem images into raw ext4 images, avoiding the need for the full Android build chain.

This package provides a tool for manipulating old Android Boot Images. abootimg can work directly on block devices, or, the safest way, on a file image.

This package provides library and command line interface for communicating with Xiaomi smart appliances over miIO and MIoT protocols.

android-ext4-utils is a library in common use by the Android core.

The libselinux library provides an API for SELinux applications to get and set process and file security contexts, and to obtain security policy decisions. It is required for any applications that use the SELinux API, and used by all applications that are SELinux-aware. This package also includes the core SELinux management utilities.

adb is a versatile command line tool that lets you communicate with an emulator instance or connected Android device. It facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that can run commands on the connected device or emulator.

android-libutils provides utilities for Android NDK developers.

Google Test features an XUnit test framework, automated test discovery, death tests, assertions, parameterized tests and XML test report generation.

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

This package provides a drop-in replacement for sdkmanager from the Android SDK. It is written in Python and part of the F-Droid project. It implements the exact API of the Android sdkmanager command line. The project also attempts to maintain the same terminal output.

etc1 is a command line utility that lets you encode PNG images to the ETC1 compression standard and decode ETC1 compressed images back to PNG. This tool is part of the Android SDK for working with media files for game apps.

The standard for the ETC1 texture format can be found at http://www.khronos.org/registry/gles/extensions/OES/OES_compressed_ETC1_RGB8_texture.txt.

Android applications are Java programs that run on a customized virtual machine, which is part of the Android operating system, the Dalvik VM. Their bytecode differs from the bytecode of normal Java applications. Enjarify can translate the Dalvik bytecode back to equivalent Java bytecode, which simplifies the analysis of Android applications. It's an alternative fork of not maintained Goole's project https://github.com/google/enjarify.

While the Android client integrates with the system with regular update checks and notifications, this is a simple command line client that talks to connected devices via ADB.

android-bionic-uapi provides the part of the Linux API that is safe to use for user space. It also includes system_properties.h and _system_properties.h.

Androguard is a full Python tool to manipulate Android files. It is useful for reverse engineering, analysis of Android applications and more.

This package is an Emacs interface to F-Droid. Its purpose is to aid in the management of F-Droid packages for an Android device or an emulator inside the comfort of Emacs.

This package provides fastboot, a tool to upload file system images to Android devices.

android-make-stub provides stubs for the make system of the Android platform. This allows us to use their packages mostly unmodified in our Android NDK build system.
