Unity3D 调用Android原生方法_androidjavaobject call

//获取当前App的Activity
	public static AndroidJavaObject Current()
    {
        if (Application.platform == RuntimePlatform.Android)
            return new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
        else
            return null;
    }
 
	//获取指定包名的Activity
	public static AndroidJavaObject GetActivity(string package_name,string activity_name)
    {
        return new AndroidJavaClass(package_name).GetStatic<AndroidJavaObject>(activity_name);
    }

3.调用Android原生方法

// UI线程中运行
	public static void RunOnUIThread(AndroidJavaRunnable r)
    {
        Current().Call("runOnUiThread", r);
    }
 
	//获取包名
	public static string getPackageName()
    {
        return Current().Call<string>("getPackageName");
    }
	//讲解：call<返回值类型>("方法名");
 
	//设置 不自动锁屏
	public static void DisableScreenLock()
    {
        Current().Call<AndroidJavaObject>("getWindow")
            .Call("addFlags",128);
    }
	//讲解：call("方法名",参数1);
 
    // 获取内置SD卡路径
    public static string GetStoragePath()
    {
        if (Application.platform == RuntimePlatform.Android)
            return new AndroidJavaClass("android.os.Environment").CallStatic<AndroidJavaObject>("getExternalStorageDirectory").Call<string>("getPath");
        else
            return "d:/movie";
    } 
	//讲解：new AndroidJavaClass("全类名")  ---new一个Android原生类
	//讲解：CallStatic<返回类型>("方法名")  ---静态方法获取一个Android原生类型
