This is a Matter TV Casting Android app that can be used to cast content to a TV. This app discovers TVs on the local network that act as commissioners, lets the user select one, sends the TV a User Directed Commissioning request, enters commissioning mode, advertises itself as a Commissionable Node and gets commissioned. Then it allows the user to send Matter ContentLauncher commands to the TV.
You need Android SDK 21 & NDK downloaded to your machine. Set the $ANDROID_HOME environment variable to where the SDK is downloaded and the $ANDROID_NDK_HOME environment variable to point to where the NDK package is downloaded.
TARGET_CPU can have the following values, depending on your smartphone CPU architecture:
| ABI | TARGET_CPU |
|---|---|
| armeabi-v7a | arm |
| arm64-v8a | arm64 |
| x86 | x86 |
| x86_64 | x64 |
We are using Gradle 7.1.1 for all android project which does not support Java 17 (https://docs.gradle.org/current/userguide/compatibility.html) while the default JDK version on MacOS for Apple Silicon is ‘openjdk 17.0.1’ or above.
Using JDK bundled with Android Studio will help with that.
export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/Contents/Home/
Complete the following steps to prepare the Matter build:
Check out the Matter repository.
Run bootstrap (only required first time)
source scripts/bootstrap.sh
This is the simplest option. In the command line, run the following command from the top Matter directory:
./scripts/build/build_examples.py --target android-arm64-tv-casting-app build
See the table above for other values of TARGET_CPU.
The debug Android package app-debug.apk will be generated at out/android-$TARGET_CPU-tv-casting-app/outputs/apk/debug/, and can be installed with
adb install out/android-$TARGET_CPU-tv-casting-app/outputs/apk/debug/app-debug.apk
You can use Android Studio to edit the Android app itself and run it after build_examples.py, but you will not be able to edit Matter Android code from src/controller/java, or other Matter C++ code within Android Studio.
