网页链接拉起Unity Android和iOS APP

1、安卓端代码

package cn.net.xuefei.schemedemo;

import android.net.Uri;
import android.os.Bundle;
import android.util.Log;

import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
 
public class MainActivity extends UnityPlayerActivity {

    private String launchInfo="";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        launchInfo = onLaunchInfo();
    }

    @Override
    public void onResume()
    {
        super.onResume();
        launchInfo = onLaunchInfo();
    }

    private String onLaunchInfo()
    {
        String info="";
        Uri uri = getIntent().getData();
        if (uri != null) {
            // 完整的url信息
            String url = uri.toString();

            info = url;
            Log.e("Unity", "url: " + url);
        }
        return info;

    }

    public void getLaunchInfo()
    {
        UnityPlayer.UnitySendMessage("Main Camera", "OnLaunchInfo", launchInfo);
        launchInfo="";
    }
}

2、Unity中 AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package = "cn.net.xuefei.schemedemo"
    android:versionCode="1"
    android:versionName="1.0">

  <application
      android:allowBackup="true"
      android:icon="@drawable/app_icon"
      android:label="@string/app_name"
      android:supportsRtl="true">

    <activity android:name=".MainActivity" >
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.BROWSABLE" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:scheme="scheme"
              android:host="host"
              android:path="/path"
              android:port="8888"/>
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    </activity>
  </application> 
</manifest>

3、Unity中代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

#if UNITY_IOS
using System.Runtime.InteropServices;
#endif

public class SchemeDemo : MonoBehaviour
{
    public Text text;

    // Use this for initialization
    void Start()
    {
        GetInfo();
    }

    // Update is called once per frame
    void Update()
    {

    }

    public void OnLaunchInfo(string launchInfo)
    {
        Debug.LogError("launchInfo:" + launchInfo);
        text.text = launchInfo;
    }

    public void GetInfo()
    {
        
#if UNITY_ANDROID
        AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
        jo.Call("getLaunchInfo");
#elif UNITY_IOS
        _GetLaunchInfo();
#endif
    }

    private void OnApplicationFocus(bool focus)
    {
        Debug.LogError("focus:" + focus);
        if (true)
        {
            GetInfo();
        }
    }

#if UNITY_IOS
    [DllImport("__Internal")]
    private static extern void _GetLaunchInfo();
#endif
}

4、设置Unity iOS URL Schemes,修改导出的Xcode工程中的UnityAppController.mm

#import "UnityAppController.h"

NSString *URLString = @"";

// 向Unity传递参数；
extern void UnitySendMessage(const char *, const char *, const char *);

//添加的代码
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
    URLString = [url absoluteString]; 
    return YES;
}

- (BOOL)application:(UIApplication*)application openURL:(NSURL*)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation
{
	//添加的代码
	URLString = [url absoluteString]; 
	return YES;
}

extern "C"  
{  
    void _GetLaunchInfo();  
}  
  
void _GetLaunchInfo()  
{    
    UnitySendMessage( "Main Camera", [@"OnLaunchInfo" UTF8String], [URLString UTF8String] );  
    // 清空，防止造成干扰;  
    URLString = @"";  
}  

5、网页

<!doctype html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0">

</head>
<body>
	<input  id="btn" type="button" value="唤起SchemeDemo">
	<script>
		var btn = document.getElementById('btn');
		
		btn.onclick = function () {
			jump('scheme://host:8888/path?ps=123456');
		};
		
		function  GetMobelType()  {                
			var  browser  =   {                    
				versions:   function()  {                        
					var  u  =  window.navigator.userAgent;    
					console.log(u);  //Safari浏览器 Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/11.1.1 Safari/605.1.15                  
					return  {                            
						trident:  u.indexOf('Trident')  >  -1, //IE内核

						mobile:  !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
						ios:  !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
						android:  u.indexOf('Android')  >  -1  ||  u.indexOf('Linux')  >  -1, //android终端或者uc浏览器
						iPhone:  u.indexOf('iPhone')  >  -1  ||  u.indexOf('Mac')  >  -1, //是否为iPhone或者安卓QQ浏览器
						//iPhone: u.match(/iphone|ipod|ipad/),//

						qq: u.match(/\sQQ/i) !== null, //是否QQ
						Safari:  u.indexOf('Safari')  >  -1,
						  ///Safari浏览器,
					};                    
				}()                
			};                
			return  browser.versions;            
		}
		
		
		function jump(myurl) { 
			var timeout = 2300, timer = null;
			if(GetMobelType().weixin) {
				// 微信浏览器不支持跳转
				// 可以显示提示在其他浏览器打开
			} else {
				var startTime = Date.now();
				if(GetMobelType().android) {
					var ifr = document.createElement('iframe');
					ifr.src = myurl;//这里是唤起App的协议，有Android可爱的同事提供
					ifr.style.display = 'none';
					document.body.appendChild(ifr);
					timer = setTimeout(function() {
						var endTime = Date.now();
						if(!startTime || endTime - startTime < timeout + 300) {
							document.body.removeChild(ifr);
							//window.open("唤起失败跳转的链接");
							window.open("https://www.ganghood.net.cn/SchemeDemo.apk");
						}
					}, timeout);
				}
				if(GetMobelType().ios || GetMobelType().iPhone || GetMobelType().iPad) {
					if(GetMobelType.qq) { 
					// ios的苹果浏览器
					// 提示在浏览器打开的蒙板
					} else {
						/*var ifr = document.createElement("iframe");
						ifr.src = myurl;

						window.location.href = myurl; //唤起协议，由iOS小哥哥提供

						timer = setTimeout(function() {

						}, timeout);
					};
				}
