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.

IML is a C library implementing algorithms for computing exact solutions to dense systems of linear equations over the integers. Currently, IML provides the following functionality:

• Nonsingular rational system solving: compute the unique rational solution X to the system AX=B, where A and B are integer matrices, A nonsingular.

• Compute the right nullspace or kernel of an integer matrix.

• Certified linear system solving: compute a minimal denominator solution x to a system Ax=b, where b is an integer vector and A is an integer matrix with arbitrary shape and rank profile.

In addition, IML provides some low level routines for a variety of mod p matrix operations: computing the row-echelon form, determinant, rank profile, and inverse of a mod p matrix. These mod p routines are not general purpose; they require that p satisfy some preconditions based on the dimension of the input matrix (usually p should be prime and should be no more than about 20 bits long).

GMP-ECM factors integers using the elliptic curve method (ECM) as well as the P-1 and P+1 algorithms. It provides a library and a stand-alone binary.

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

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.

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.

This package contains headers used for developing software for Android. More precicely the headers from include/android in platform/frameworks/native.

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

This package provides a tool to create Android Boot Images.

android-f2fs-utils is a library in common use by the Android core. It allows the user to create images for the f2fs Flash file system.

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.

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.

libcutils is a library in common use by the various Android core host applications.

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

liblog represents an interface to the volatile Android Logging system for NDK (Native) applications and libraries and contain interfaces for either writing or reading logs. The log buffers are divided up in Main, System, Radio and Events sub-logs.

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.

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.

android-libsparse is a library in common use by the various Android core host applications.

Ericsson Texture Compression (ETC) is a lossy texture compression technique developed in collaboration with Ericsson Research in early 2005. libETC1 provides the encoding and decoding of ETC1 compression algorithm.

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 Qt graphical interface for transferring files with Android devices using MTP. It also allows the Android device to be mounted via FUSE.

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.

The F-Droid server tools provide various scripts and tools that are used to maintain F-Droid, the repository of free Android applications. You can use these same tools to create your own additional or alternative repository for publishing, or to assist in creating, testing and submitting metadata to the main repository.

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.
