Hello, I'm very appreciated the swift-android toolchain you guys built. So I want to build and run this project personally, after set up the environment like the project said (https://github.com/readdle/swift-android-toolchain) , when I started build this project, I meet this error: Process 'command '/swift-android-5.0-r13/build-tools/1.9.6-swift5/swift-build'' finished with non-zero exit value 134. I fail to resolve this issue after many attempts, so here I come to ask you help, could you help me to check what's went wrong.

I list all the related information below:

1. MacOS Version: Catalina version 10.15.4
2. Android Studio Version: 4.2.2
3. Gradle Version: 6.7.1, Android Studio Gradle plugin Version: 4.2.0
4. swift-android-toolchain: 5.0-r13

Here is the build error I meet:

Here is my environment variable setting in case you want to check it.

I'm looking forward for your reply

Hi,

1. Do you install the proper version of swift on your mac?

[IMPORTANT] Install Swift 5.0.3 toolchain for Xcode https://swift.org/builds/swift-5.0.3-release/xcode/swift-5.0.3-RELEASE/swift-5.0.3-RELEASE-osx.pkg

I don't see export TOOLCHAINS=org.swift.50320190830a in your environment setup
Looks like you try to use the android toolchain with your current XCode Swift 5.4. Please follow instructions from the readme.

2. Also, it's weird that you can't clone our project from Github

fatal: unable to access 'https://github.com/readdle/swift-android-buildtools/': LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443

Please try to clone in separately:

git clone https://github.com/readdle/swift-android-buildtools

Seems like you have some SSL issues on your machine.

[EddieMeng]

Hello, I did set export TOOLCHAINS=org.swift.50320190830a, but the screenshot above is not complete, here is the completed info

export TOOLCHAINS=org.swift.50320190830a

NDK=17c
export ANDROID_NDK_HOME=/Users/Eddie/Downloads/Android/NDK/android-ndk-r$NDK

export NDK_ROOT=$ANDROID_NDK_HOME
export ANDROID_NDK=$ANDROID_NDK_HOME
export ANDROID_NDK_ROOT=$ANDROID_NDK_HOME

export SWIFT_ANDROID_HOME=$HOME/android/swift-android-current
export PATH=$ANDROID_NDK_HOME:$PATH
export PATH=$SWIFT_ANDROID_HOME/bin:$SWIFT_ANDROID_HOME/build-tools/current:$PATH

OH, yes, I have no idea why I got the ssl issue, but looks like the log tell me swift build tools completed regardless of the ssl issue

[EddieMeng]

I found that ssl issue is the network issue, the latest build info don't report the ssl issue again

By the way I build this project by this command: ./gradlew aseembleDebug, is that okay?
@andriydruk

[andriydruk]

Yes, it's ok. We use Gradle build in our CI

Toolchain somewhy can't find your swift installation
Could you check your swift version?

swift --version

[EddieMeng]

please check @andriydruk

[EddieMeng]

is it matter with the mac os version, what's your build server mac os version? I don't have clue about why this build error occur. @andriydruk

[andriydruk]

Hmm, the swift version looks ok.
It should work with BigSur and Catalina. We use macos-latest on Github CI which is Catalina for now https://github.com/actions/virtual-environments

Maybe try to clean up the project/environment. Check our CI script maybe it will help you
https://github.com/andriydruk/swift-weather-app/blob/master/.github/workflows/android-ui.yml

[EddieMeng]

Is your build server build the app by android studio or just gradle? and by the way, what the CI software are you using? @andriydruk

[EddieMeng]

I wanna confirm that is this project build by the github CI server?

[andriydruk]

We use Gradle in this CI script. But should work with Android Studio as well.
And yes it's public Github CI without any priority servers
https://docs.github.com/en/actions

[EddieMeng]

@andriydruk Hello andriydruk, thanks for your patient help. I tried the script in github server, it did build successfully. But when I tried to build the project in two different mac os machines, both met this error. Besides, I think I'm not the only one met this error refer to
readdle/swift-android-toolchain#20 , so it is probably a common issue in local build. I wanna know had this project ever built successfully in your guys mac os machine? so that I can figure out what went wrong.

[EddieMeng]

Sir, any update on this? @andriydruk

[andriydruk]

I have one more assumption: maybe problem with the macOS version. In Readdle everybody uses the latest version of Big Sur.
Github CI provides macOS 10.15.7 and macOS 11.4
I will add one more CI script to double-check that everything works on both Catalina and Big Sur

[EddieMeng]

@andriydruk Sir, your assumption is correct, after I upgrade the system to latest version of Big Sur, I built the app successfully. I'm very appreciated this toolchain your guys created, the idea is awesome, please keep making it better and better. Besides, I am a fans of Spark email, which is powerful and intelligent, saving me lots of time. is the toolchain was applied in all the projects in Readdle?

[andriydruk]

@EddieMeng thank you for so warm words! We do our best to provide a good experience for all our users. And we are glad to share our expertise with the developer community.

Currently, we use the Swift Android toolchain only in Spark because it's the only Readdle's app on the Android platform 🙃
