Learn Code Lab
codelabmatter create a virtual device and make an open source contribution objective learn how to create a matter virtual device, which you can control using the smartthings app also, know how to contribute your code to matter open source overview matter is an open-source connectivity standard for smart home and internet of things iot devices it is a secure, reliable, and seamless cross-platform protocol for connecting compatible devices and systems with one another smartthings provides the matter virtual device app and smartthings home apis to help you quickly develop matter devices and use the smartthings ecosystem without needing to build your own iot ecosystem you can use smartthings home apis to onboard, control, remove, and share all matter devices when building your application other iot ecosystems can use the matter devices onboarded on your iot app through the multi-admin function notethis code lab focuses only on creating a matter virtual device you can control using the smartthings app to learn how to make your controller app, see build a matter iot app with smartthings home apis for detailed information, go to partners smartthings com/matter set up your environment you will need the following host pc running on windows 10 or higher or ubuntu 20 04 x64 android studio latest version recommended java se development kit jdk 11 or later devices connected on the same network mobile device with android 8 0 oreo or higher operating system os mobile device with smartthings app installed matter-enabled smartthings station onboarded with samsung account used for smartthings app initial setup turn on developer mode and enable usb debugging option on your mobile device install a few os-specific dependencies by entering the below command in your terminal window $ sudo apt-get install git gcc g++ pkg-config libssl-dev libdbus-1-dev \ libglib2 0-dev libavahi-client-dev ninja-build python3-venv python3-dev \ python3-pip unzip libgirepository1 0-dev libcairo2-dev libreadline-dev to build the matter virtual device app, install sdk platform 26 and ndk version 22 1 7171670 using sdk manager in android studio after installing ndk, register the ndk path to the env path export android_ndk_home=[ndk path] export path=$path ${android_ndk_home} install kotlin compiler kotlinc version 1 5 10 after installing kotlinc, register the kotlinc path to the env path export kotlinc_home=[kotlinc path]/bin export path=$path ${kotlinc_home} sample code here is a sample code for you to start coding in this codelab download it and start your learning experience! matter virtual device sample code 11 42 mb start your project after downloading the sample code containing the project files, open your android studio and click open to open an existing project locate the downloaded android project from the directory and click ok select and create the device type when you build and run the sample matter virtual device app, you can see the already added on/off switch aside from the switch, other types of devices you can create are already prepared in the sample app noterefer to the matter device library specification for the list of matter

matter open source, you need to have the latest code therefore, apart from the project files provided by this code lab activity, you should fork and modify the latest code from matter open source project matter follows the "fork-and-pull" model for accepting contributions to do this sign in or sign up to github fork the matter repository by clicking fork on the web ui for each new feature, clone your fork to the local pc and create a working branch $ git clone https //github com/<username>/connectedhomeip git $ git checkout –b <branch-name> before running the build command, source the environment setup script activate sh at the top level this script takes care of downloading gn, ninja, and setting up a python environment with libraries used to build and test $ source scripts/activate sh build the virtual device app using the build_example py $ /scripts/build/build_examples py --target android-arm64-virtual-device-app build add each modified file to include in the commit then, create a commit $ git add <filename1> <filename1> $ git commit –s noteto contribute to the open source, you must check the integrity of the code for this, checking using restyle is recommended push to your github fork $ git push origin <branch-name> then, submit your pull request by clicking contribute > open pull request on the web ui write a description of the problem, change overview, and test then, sign the contributor license agreement cla so a reviewer can automatically be assigned click open pull request tipsee contributing to matter for more information you're done! congratulations! you have successfully achieved the goal of this code lab topic now, you can create a matter-compatible virtual device and contribute your code to matter open source by yourself! if
