CodeAssist
What CodeAssist is
CodeAssist is a free, on-device IDE for editing and building Android and Java projects. It builds, signs, and installs APKs on Android without a Gradle daemon. Java code intelligence, powered by Eclipse JDT, provides completion, diagnostics, and quick fixes; Kotlin completion is labeled beta. Java files can also be edited in a Scratch-style block view, with changes written back to source. Supported languages include Java, Kotlin, C, and C++, and app packaging is available. On-device Git supports GitHub sign-in, cloning private repositories, publishing repositories, and opening pull requests. A CodeAssist GitHub Action can build CodeAssist projects in CI and annotate compiler errors on the diff. The project is licensed under GPL-3.0-or-later, with a Classpath exception for specified plugin APIs. Its privacy policy says project source, files, paths, project data, and credentials stay on the device. Optional performance and crash telemetry is off by default; when enabled, it is sent over HTTPS and stored using Supabase. Distribution options include the Google Play testing track, F-Droid, and IzzyOnDroid. Support is offered through Discord.
