Unity中调用Android方法实现分享功能

using UnityEngine;
#if UNITY_ANDROID
using System.Collections;
#endif

public static void ShareText(string message)
{
    #if UNITY_ANDROID
    AndroidJavaClass shareClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject currentActivity = shareClass.GetStatic<AndroidJavaObject>("currentActivity");
    AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
    string intentAction = intentClass.GetStatic<string>("ACTION_SEND");
    AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent", intentAction);
    intentObject.Call<AndroidJavaObject>("setType", "text/plain");
    intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), message);
    currentActivity.Call("startActivity", intentObject);
    #endif
}

public void OnShareButtonClicked()
{
    ShareManager.ShareText("分享内容");
}
