Matter Controller Java App Example#

This is a Matter Controller Java app that can be used to commission and control Matter accessory devices. It offers the following features: - Commission a Matter device - Send echo requests to the Matter echo server - Send on/off cluster requests to a Matter device



Requirements for building#

You need to have the following two software installed on your Ubuntu system:

  1. Java Runtime Environment (JRE)

  2. Java Development Kit (JDK)

java -version

This will ensure either Java Runtime Environment is already installed on your system or not. In order to install the Java Runtime Environment on your system, run the following command as root:

sudo apt install default-jre Install Java default JRE

After installing the JRE, let us check if we have the Java Development Kit installed on our system or not.

javac -version

The above output shows that I need to install the Java compiler or the JDK on my system. You can install it through the following command as root:

sudo apt install default-jdk

Linux#

export JAVA_PATH=[JDK path]

Preparing for build#

Complete the following steps to prepare the Matter build:

  1. Check out the Matter repository.

  2. Run bootstrap (only required first time)

    source scripts/bootstrap.sh
    

Building & Running the app#

This is the simplest option. In the command line, run the following command from the top Matter directory:

./scripts/build/build_examples.py --target linux-x64-java-matter-controller build

The Java executable file java-matter-controller will be generated at out/android-x86-java-matter-controller/bin/

Run the java-matter-controller

java -Djava.library.path=../lib/jni -jar java-matter-controller
