Android中嵌入Unity_android 嵌入unity

Android内嵌Unity

参考文章：Android/iOS内嵌Unity开发示例 - zhxmdefj - 博客园 (cnblogs.com)https://www.cnblogs.com/zhxmdefj/p/13273560.html

参考视频：Embedded unity within the android app Part II - YouTubehttps://www.youtube.com/watch?v=sf54tOAkmzU

Android与unity交互步骤：

1、Unity中调用Android方法

1）将Android编写好方法并Build后，把Android中的app/build/intermediates/aar_main_jar/debug中的classes.jar导入unity项目中Plugins/Android文件夹中

2）在脚本中调用Android项目的方法，具体方法如下：

        //通过类直接访问静态属性与方法
        javaClass = new AndroidJavaClass("com.zy.testunity.Test");
        //通过对象访问非静态属性与方法
        javaObject = new AndroidJavaObject("com.zy.testunity.Test");

2、Android中调用Unity方法

1）把unity引擎目录下的\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes中的classes.jar导入项目app/libs文件夹下，导入后右击classes.jar唤出菜单，点击Add As Library...来将该jar包添加为库。

2）在Android项目的java类中调用unity方法，具体方法如下：

//UnitySendMessage("场景内游戏物体名称","脚本方法名称","方法参数")
//传递的参数是一个字符串，多个参数通过分割字符串来获取
UnityPlayer.UnitySendMessage("Canvas","GetLog","");

Android中嵌入Unity问题总结：

1、模块地址填写错误

 2、主模块与unity模块sdk版本不统一

3、主模块与unity模块最小sdk版本不统一

4、ndk未配置

5、未在gradle.properties中配置unityStreamingAssets

bug2：

初步鉴定：unity模块sdk版本选择错误

> Task :app:processDebugMainManifest FAILED
G:\Combination\NativeAndroidApp\app\src\main\AndroidManifest.xml Error:
	uses-sdk:minSdkVersion 17 cannot be smaller than version 22 declared in library [:unityLibrary] G:\Combination\UnityProject\unityLibrary\build\intermediates\merged_manifest\debug\AndroidManifest.xml as the library might be using APIs not available in 17
	Suggestion: use a compatible library with a minSdk of at most 17,
		or increase this project's minSdk version to at least 22,
		or use tools:overrideLibrary="com.unity3d.player" to force usage (may lead to runtime failures)
See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.
