如何访问Android里面的数组元素

很简单，对于类对象，要保证在Android不能为空

  void Awake()
    {
        AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
        activity.Call("setListener", new ActivityListener());
        int fieldValue = activity.Get<int>("fieldValue");
        UnityEngine.Debug.LogError("Test GetField : " + fieldValue);
        activity.Set<int>("fieldValue", 9999999);
        fieldValue = activity.Get<int>("fieldValue");
        UnityEngine.Debug.LogError("Test SetField : " + fieldValue);

        var length = activity.Call<AndroidJavaObject[]>("Test");
        UnityEngine.Debug.LogError("CallObjectArray : " + fieldValue);
        UnityEngine.Debug.LogError("CallObjectArrayReturn Length: " + length);

        activity.Call<AndroidJavaObject[]>("Test")[0].Call("GetTest");
        UnityEngine.Debug.LogError("Array Then call deep method" );

        int index = activity.Call<AndroidJavaObject[]>("Test")[0].Get<int>("index");
        UnityEngine.Debug.LogError("Array Then call deep variables : " + index);

        string []srs = activity.Call<string[]>("GetStrings");
        UnityEngine.Debug.LogError("return string array :  " + srs[0]);
        UnityEngine.Debug.LogError("return string array :  " + srs[1]);

        byte[] bytes = activity.Call<byte[]>("GetBytes");
        UnityEngine.Debug.LogError("bytes.Length : === " + bytes.Length);
    }

  public void setListener()
    {
    	Log.v("Unity", "setListener()!------------");
    }

    public Player[] Test()
    {
    	Log.v("Unity", "test!------------");
    	Player[] ps = new Player[2];
    	ps[0] = new Player();
    	ps[1] = new Player();
    	
    	return ps;
    }
    
    public String[] GetStrings()
    {
    	String[] sarray = new String[2];
    	sarray[0] = "hahahStr1";
    	sarray[1] = "getStr2";
    	return sarray;
    }
    
    public byte[] GetBytes()
    {
    	return new byte[10];
    }

public class Player {

	public int index = 12321321;
	public void GetTest()
	{
		Log.v("Unity", "setListener(1)!------------");
	}
}
