Android应用内嵌unity3d游戏项目

在一个现有的Android项目中嵌入unity3d项目

1.将unity3d项目导出android工程

2.将第一步导出的Android工程中assets文件夹和libs文件夹下的所有内容复制到Android项目中对应的assets和libs文件夹下

3.Android调转到unity

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        startGameBtn = (Button) findViewById(R.id.StartGameButton);
        startGameBtn.setOnClickListener(new OnClickListener() {
