将值从Android Studio传递给unity？

using UnityEngine;

public class AndroidBridge : MonoBehaviour
{
    public static void ReceiveMessage(string message)
    {
        Debug.Log("Received message from Android: " + message);
    }
}

UnityPlayer.UnitySendMessage("GameObjectName", "ReceiveMessage", "Hello from Android");

Intent intent = new Intent(this, UnityPlayerActivity.class);
intent.putExtra("key", "value");
startActivity(intent);

using UnityEngine;

public class AndroidBridge : MonoBehaviour
{
    void Start()
    {
        string value = PlayerPrefs.GetString("key");
        Debug.Log("Received value from Android: " + value);
    }
}

FileOutputStream fos = openFileOutput("shared_data.txt", MODE_PRIVATE);
fos.write("Hello from Android".getBytes());
fos.close();

using System.IO;
using UnityEngine;

public class AndroidBridge : MonoBehaviour
{
    void Start()
    {
        string path = Path.Combine(Application.persistentDataPath, "shared_data.txt");
        if (File.Exists(path))
        {
            string content = File.ReadAllText(path);
            Debug.Log("Received content from Android: " + content);
        }
    }
}
