Unity打包发布后正确读取StreamingAssets文件夹下文件跟调用手机邮箱像指定邮箱地址发邮件

因为项目需要调手机浏览器从StreamingAssets文件夹打开Html文件,花了一天时间查看Unity官方API跟一些论坛帖子,做的一个DEMO

代码在这里插入代码片

public class NativeShareAndroid : MonoBehaviour
{
public Text waitObject;

public TextAsset fileInfo;

void Awake()
{
  
    StartCoroutine(url());
}





public void OnShareNative()
{//这里是邮箱内容
    string email = "[email protected]";
    string subject = MyEscapeURL("");//邮件预设主题
    string body = MyEscapeURL("");//邮件预设内容
    Application.OpenURL("mailto:" + email + "?subject=" + subject + "&body=" + body);

    waitObject.text = "链接中...";
}
string MyEscapeURL(string url)
{
    //%20是空格在url中的编码，这个方法将url中非法的字符转换成%20格式
    return WWW.EscapeURL(url).Replace("+", "%20");
}

{

#if UNITY_EDITOR_WIN || UNITY_STANDALONE_WIN

    }
    else
    {
        path = Application.persistentDataPath + filepath + ".html";
    }
    //直接用附带的浏览器打开Html文件
    Application.OpenURL(path);
}


public IEnumerator url()
{
    yield return new WaitForSeconds(0.5f);//先等待0.5S 等截面渲染出来再执行
    string surl = GetStreamingAssetsPath("TEST.html");

    Debug.Log(aa);

        waitObject.text = Application.persistentDataPath;
        File.WriteAllBytes(path, aa.bytes);
    }

  
   
}

    }
    else
    {
        return "找到配置文件：" + path;
    }

    
}




public static string GetStreamingAssetsPath(string path)
{//当前系统判断
    if (Application.platform == RuntimePlatform.Android)
    {
        return Application.streamingAssetsPath + "/" + path;
    }
    else if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        return GetPath() + Application.streamingAssetsPath + "/" + path;
    }
    else if (Application.platform == RuntimePlatform.OSXEditor)
    {
        return GetPath() + Application.streamingAssetsPath + "/" + path;
    }
    else if (Application.platform == RuntimePlatform.WindowsPlayer)
    {
        return "file://" + Application.streamingAssetsPath + "/" + path;
    }
    else if (Application.platform == RuntimePlatform.WindowsEditor)
    {


        ///编辑模式下测试路径
        return Application.streamingAssetsPath + "/" + path;
    }

    return "";
}

}
