[Rifatgh]

i am facing same problem with unity 6

Configure project :unityLibrary
Variant 'debug', will keep symbols in binaries for:
'libunity.so'
'libil2cpp.so'
'libmain.so'
Variant 'release', symbols will be stripped from binaries.

Configure project :launcher
Variant 'debug', will keep symbols in binaries for:
'libunity.so'
'libil2cpp.so'
'libmain.so'
Variant 'release', symbols will be stripped from binaries.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.4/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

• What went wrong:
  A problem occurred configuring project ':unityLibrary:eos_dependencies.androidlib'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

 If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file.

This issue is occurring due to the Gradle version being updated for Android builds in Unity 6000.

The error occurs at:
2nd error
FAILURE: Build failed with an exception.
What went wrong: A problem occurred configuring project ':unityLibrary:eos_dependencies.androidlib'.

The build is failing because the new Gradle plugin requires adding a namespace.
To fix this issue, modifying the build.gradle for this plugin to the following will likely allow successful builds on Windows:

buildscript {
    repositories {
        google()
        mavenCentral()
        flatDir(dirs: 'libs')
    }
   
    dependencies {
        classpath "com.android.tools.build:gradle:8.6.0"
    }
}
 
apply plugin: 'com.android.library'
 
android {
    namespace "com.pew.eos_dependencies"
 
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
        }
    }
 
    compileSdkVersion 34
    buildToolsVersion '34.0.0'
    defaultConfig {
        targetSdkVersion 34
    }
}
dependencies {
        implementation 'androidx.appcompat:appcompat:1.6.1'
        implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
        implementation 'androidx.security:security-crypto:1.0.0'
        implementation 'androidx.browser:browser:1.4.0'
        implementation 'androidx.webkit:webkit:1.7.0'
}

However, since this fix doesn't work properly for macOS builds, it cannot be implemented in the next update.

Hi skeyll ,
Any rough idea when can we expect if for macOs too?

[Rifatgh]

which version of unity you used for this, i tried with 2021's two version LTSand 6LTS Unity 6's two version

Overall this seems to work.

I do get runtime errors, but they don't seem to cause any issues? Notably login using connect, and saving and loading player save files is working again on Android.

@Rifatgh I used PlayEveryware EOS 3.3.2 on Unity 6000.0.19f1.
I'd assume Unity 6 LTS would work fine.

@kdserra Could you please share your experience? hows game running, any noticeable issues preventing it to use in production?
Thanks

For Unity 6, it is likely that the .androidlib build works slightly different than Unity 2021.
We will have to take a closer look at it, because it might require a big file rearranging to work, and will also mean the same repo won't work on both versions at the same time.
We still need to investigate though.

About macOS, do we mean building android on macOS here?
