[build] android_building.md Flamingo Android Studio Java instructions #27797

Open willysagefalk opened 1 year ago

willysagefalk commented 1 year ago

Made a fresh install of Ubuntu 22.04.2 LTS

Installed Android Studio using "software" in Ubuntu Android Studio Flamingo | 2022.2.1 Patch 1

According to Building instruction you should set JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home/

Java was not found using that path ./scripts/build/build_examples.py --target android-arm64-chip-tool build 2023-07-07 10:20:09 INFO Building targets: android-arm64-chip-tool 2023-07-07 10:20:09 INFO Preparing builder 'android-arm64-chip-tool' 2023-07-07 10:20:09 INFO Generating /home/willy/matter/connectedhomeip/out/android-arm64-chip-tool 2023-07-07 10:20:09 INFO Setting up Android deps through Gradle 2023-07-07 10:20:09 WARNING 2023-07-07 10:20:09 WARNING ERROR: JAVA_HOME is set to an invalid directory: /Applications/Android Studio.app/Contents/jbr/Contents/Home/ 2023-07-07 10:20:09 WARNING 2023-07-07 10:20:09 WARNING Please set the JAVA_HOME variable in your environment to match the 2023-07-07 10:20:09 WARNING location of your Java installation.

In Android Studio Flamingo I found default Java
JAVA_HOME=/snap/android-studio/126/android-studio/jbr

When I check version it appears to be version 17.0.06 however /snap/android-studio/126/android-studio/jbr/bin/java --version openjdk 17.0.6 2023-01-17 OpenJDK Runtime Environment (build 17.0.6+0-17.0.6b802.4-9586694) OpenJDK 64-Bit Server VM (build 17.0.6+0-17.0.6b802.4-9586694, mixed mode)

So unsure how to set JAVA_HOME correctly using Flamingo

Building from scripts worked without JAVA_HOME using sudo apt install openjdk-11-jdk-headless sudo snap install --classic kotlin /scripts/build/build_examples.py --target android-arm64-chip-tool build

The resulting APK runs fine on an Android Phone

I think the JAVA_HOME value is relevant to Mac OSX, not Linux.

could you consider to use docker to complete android chip-tool docker run -it -v ~/workspace/connectedhomeip:/connectedhomeip ghcr.io/project-chip/chip-build-android:1 git config --global --add safe.directory /connectedhomeip git config --global --add safe.directory /connectedhomeip/third_party/pigweed/repo source scripts/bootstrap.sh ./scripts/build/build_examples.py --target android-arm64-chip-tool build
