UnityAndroidLibrary

Export Unity Gradle Project

• Android player setting, under Android application entry points, uncheck GameActivity and check Activity

• Copy unityLibrary and shared folder from exported folder to the android project root folder which has folders like (app, gradle, .kotlin)

• make sure the root setting.gradle has below lines or add them at last

    include(":unityLibrary")
    project(":unityLibrary").projectDir = file("unityLibrary")

• unityLibrary/build.gradle replace androidResources block with below code

androidResources {
        def base = ['unity3d','ress','resource','obb','bundle','unityexp']
        def extra = []
        if (project.ext.has('unityStreamingAssets') && project.ext.unityStreamingAssets) {
            extra = project.ext.unityStreamingAssets
                    .toString()
                    .split(',')
                    .collect { it.trim().replaceFirst(/^\\./,'') }
                    .findAll { it }
        }
        noCompress = (base + extra)
        ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:!CVS:!thumbs.db:!picasa.ini:!*~"
}

• unityLibrary/build.gradle add api to dependency

dependencies {
    api fileTree(dir: 'libs', include: ['*.jar'])//add this above implementation
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}

• app/build.gradle add unityLibrary as dependency

    implementation(project(":unityLibrary"))

• app/build.gradle match javaversion with unity's java version

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = "17"
    }
