Unity调用安卓Native(Android Studio)

最后有项目下载地址
引入Unity的class.jar
Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes.jar

导出.jar包

在AS中进行操作

build.gradle修改

apply plugin: 'com.android.library'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:26.+'
    testCompile 'junit:junit:4.12'
    compile files('libs/classes.jar')
}
//task to delete the old jar
task deleteOldJar(type: Delete) {    delete 'build/outputs/NativeExit.jar'}
//task to export contents as jar
task exportJar(type: Copy) {
    from('build/intermediates/bundles/debug/')
    into('build/outputs/')
    include('classes.jar')
    ///Rename the jar
    rename('classes.jar', 'NativeExit.jar')
}
exportJar.dependsOn(deleteOldJar, build)

02.将AS中的.jar引入unity中

string CLASS_NAME = "com.xxx.xxx.PopupManager";
AndroidJavaObject bridge = new AndroidJavaObject(CLASS_NAME);
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject act = jc.GetStatic<AndroidJavaObject>("currentActivity");
act.Call("runOnUiThread", new AndroidJavaRunnable(() =>
{
    bridge.CallStatic(methodName, args);
}));

这是unity与Android交互的部分，把Android中的方法注册过来，在Unity中调用
