The short version: Install an Android SDK and run:
$ ./gradlew clean assembleDebug test
Please read the list of instructions below for specific details on configurations.
Install the Android SDK and Android Studio. We don't support the use of any other IDE at the moment.
The build requires JDK 25; the code is compiled to Java 11 bytecode.
The JAVA_HOME environment variable must be set correctly. You can check what it is set to in
most shells with echo $JAVA_HOME. If that command does not show anything, adding the following
line to $HOME/.profile and then executing source $HOME/.profile or opening a new shell
should suffice:
# Replace NNN with your particular version of 25.
export JAVA_HOME=/path/to/jdk25_NNN
You can verify that everything is set up correctly by inspecting the results of both
java -version and javac -version:
$ java -version
openjdk version "25.0.4.1" 2026-08-18 LTS
OpenJDK Runtime Environment (Red_Hat-25.0.4.1.1-1) (build 25.0.4.1+1-LTS)

The API complies with Semantic Versioning 2.0.0, and this is enforced using japicmp. The current version of the code is analyzed with respect to the previous version, and incompatible changes will require a major version increment. Please see the VERSIONING.txt file for the list of packages that are exempt from versioning rules due to being private implementation packages.
