[Build] Android sample app

[dzulhafiz-at]

Build issue(s)

1. Compiling the connectedhomeip/examples/android code failed

All of the CHIP imports are not resolved. Sample imports are: import chip.devicecontroller.ChipDeviceController import chip.devicecontroller.ClusterIDMapping.* import chip.devicecontroller.InvokeCallback import chip.devicecontroller.ReportCallback import chip.devicecontroller.ResubscriptionAttemptCallback import chip.devicecontroller.SubscriptionEstablishedCallback import chip.devicecontroller.model.ChipAttributePath import chip.devicecontroller.model.ChipEventPath import chip.devicecontroller.model.InvokeElement import chip.devicecontroller.model.NodeState import chip.tlv.AnonymousTag import chip.tlv.ContextSpecificTag import chip.tlv.TlvWriter

Extra information: I am using Windows 10 laptop

Steps I did: Clone connectedhomeip Open connectedhomeip/examples/android/CHIPTool in Android Studio Install latest NDK (Side by Side) - 25.2.9519653 Install latest Command Line Tools Install SDK 26 Add ANDROID_HOME and ANDROID_NDK_HOME into my Environment Variables Add JAVA_HOME will following value "C:\Program Files\Android\Android Studio\jre" Execute scripts/bootstrap.sh Next I tried the "Building Android CHIPTool from scripts" step but the cmd provided there is not working, so I change to "python scripts\build\build_examples.py --target android-arm64-chip-tool build" but I am getting error: Traceback (most recent call last): File "C:\xxx\AndroidStudioProjects\connectedhomeip\scripts\build\build_examples.py", line 22, in <module> import click ModuleNotFoundError: No module named 'click'

But I assume this cmd would create an APK file, right? So, I return to Android Studio and try to run the examples/android/CHIPTool code, but still the CHIP import is not resolve and when I go ahead with "Run" the app, I got this: Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed module @d1886a8

Sorry if my question here shouldn't create an issue, but I had been stuck here for few days and still couldn't figure it out how to get this code working on my machine. I would like to Debug/Run this app so that I could put breakpoint etc to understand the flow better.

Platform

android

Anything else?

@dzulhafiz-at I didn't try android ChipTool build in windows environment.

If you load the SDK's example App (example/android/ChipTool) in android studio without library copy, I think this error appears because the library is not built.

[dzulhafiz-at]

From this connectedhomeip source code, is there a way for me to import the code into Android Studio so I could play around with the Matter commissioning and sending cluster command etc from my Android phone?

You can find android build guide below URL. https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/android_building.md

I didn't try android ChipTool build in windows environment.

Do you recomand to use Linux system to build the Android sample app?

[dzulhafiz-at]

You can find android build guide below URL. https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/android_building.md

Actually this is the guide that I am referring to. I did mentioned in "Steps I did:" above what I had done but having issue at "Building Android CHIPTool from scripts" step. A bit busy now, will try again next week in Mac if able to proceed

[yunhanw-google]

You can try the below, 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 linux-x64-java-matter-controller build ./scripts/build/build_examples.py --target linux-x64-all-clusters build ./scripts/build/build_examples.py --target linux-x64-chip-tool build

@dzulhafiz-at Hello brother, has this problem been solved？

Hello everyone. After proceeding with all the steps described at https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/android_building.md I cannot build the CHIPTool app for android. I have kotlin Kotlin version 1.7.21-release-272 and did not touch the CHIPTool's files so the gradle version is gradle-7.1.1 and gradle plugin is classpath 'com.android.tools.build:gradle:4.2.0' . But I got this error:

> Task :app:compileDebugKotlin FAILED
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.

I don't know where I did wrong. Is there anyone who was able to build CHIPTool app? Thanks

@dzulhafiz-at Hello brother, has this problem been solved？

Sorry for the late reply. There was a adjustment on our solution for the app and I had some catching up to do to update the app based on new design. So, I had not revisit this ever since. I couldn't confirm if it works.
