安卓原生分享

之前在项目里，产品经理提出要加入安卓和IOS的微信，QQ,微博等的分享功能，要实现分享主要有两种方法，一种是接ShareSDK，一种是原生分享，ShareSDK需要在微信开发者平台上申请，一般需要3到5天才能审核通过，这种方法很耗时间，而我们的项目需要一周上线，很明显没有充足的时间，只能采用第二种分享，调用原生分享，这种方法方便快捷。安卓分享实际上是调用U3d的接口，IOS分享实际上是使用IOS开发，通过调用OC代码来实现的，IOS分享会在下一篇博客里给大家介绍。下面附上我的安卓分享的demo。在点击按钮时调用下面的Share方法即可。

public static void Share()
        {
            #if UNITY_ANDROID && !UNITY_EDITOR
            //定义AndroidJavaClass变量
            AndroidJavaClass UnityPlayer;
            AndroidJavaClass Intent;
            AndroidJavaClass Uri;
            AndroidJavaClass Environment;

            //实例化AndroidJavaClass变量
            UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            Intent = new AndroidJavaClass ("android.content.Intent");
            Uri = new AndroidJavaClass ("android.net.Uri");
            Environment = new AndroidJavaClass ("android.os.Environment");

            AndroidJavaObject currentActivity = UnityPlayer.GetStatic("currentActivity");

            AndroidJavaObject jstr_type = new AndroidJavaObject("java.lang.String", "text/plain");
            AndroidJavaObject jstr_content = new AndroidJavaObject("java.lang.String", "https://play.google.com/store/apps/details?id= " + Application.identifier);


            AndroidJavaObject intent = new AndroidJavaObject("android.content.Intent", Intent.GetStatic("ACTION_SEND"));
            intent.Call("setType", jstr_type);
            intent.Call("putExtra", Intent.GetStatic("EXTRA_TEXT"), jstr_content);

            currentActivity.Call("startActivity", intent);

            #endif

        }

同时可能会有发送邮件的需求，这种也很简单。下面附上代码和效果。

 public static void SendEmail (string emailAddress)
        {
            string subject = MyEscapeURL ("To:" + Application.productName);
            string body = MyEscapeURL ("To the developer team!");
            Application.OpenURL ("mailto:" + emailAddress + "?subject=" + subject + "&body=" + body);

        }

 private static string MyEscapeURL (string url)
        {
            return WWW.EscapeURL (url).Replace ("+", "%20");
        }
