Termux is an Android terminal emulator application that provides a Linux environment on mobile devices, written primarily in Java. The repository contains the core application code for the user interface and terminal emulation functionality, while installable packages are maintained separately in the termux-packages repository. The application is designed to be extensible through a variety of optional plugin applications including Termux:API, Termux:Boot, Termux:Float, Termux:Styling, Termux:Tasker, and Termux:Widget.
The application requires Android 7 or higher for full support, though limited support was restored for Android 5 and 6 devices without package updates. Installation is available through multiple sources including F-Droid, GitHub Releases, GitHub Build Actions, and an experimental Google Play Store branch. The F-Droid version is distributed as a universal APK with approximately 180MB installation size, while GitHub releases offer both universal and architecture-specific variants ranging from 120MB to 180MB depending on the architecture chosen.
A critical consideration for users is the incompatibility of APK files signed with different keys. All Termux applications and plugins use the shared user ID com.termux and must be installed from the same source to function together. Mixing installations from different sources results in installation failures, requiring complete uninstallation and reinstallation from a single consistent source. The GitHub builds use a shared test key that is publicly available for community testing purposes, which presents a security consideration that users should be aware of when obtaining builds from sources other than the official GitHub repository.
This can result in unexpected process termination with signal 9 messages.
The application is actively seeking Android application maintainers to support ongoing development.
