一、ios直接跳转对应网址
      Application.OpenURL(url)
二、android
      1、判断是否有应用
using (var jc = new AndroidJavaClass(&#34;com.unity3d.player.UnityPlayer&#34;))
{
using (var currentActivity = jc.GetStatic<AndroidJavaObject>(&#34;currentActivity&#34;))
{
      using (var packageManager = currentActivity.Call<AndroidJavaObject>(&#34;getPackageManager&#34;))
      {
         using (var pluginClass = new AndroidJavaClass(&#34;android.content.pm.PackageManager&#34;))
         {
            int flag = pluginClass.GetStatic<int>(&#34;GET_META_DATA&#34;);
            var packages =  packageManager.Call<AndroidJavaObject>(&#34;getInstalledApplications&#34;, flag);
            int count = packages.Call<int>(&#34;size&#34;);

            for (int i = 0; i < count; i++)
            {
                  var pkg = packages.Call<AndroidJavaObject>(&#34;get&#34;, i);
                  var pkgName = pkg.Get<string>(&#34;packageName&#34;);

                  if (pkgName == packageName)
                  {
                     Debug.LogWarning(&#34;ThirdAppUtil IsPackageInstalled  &#34; + packageName);
                     return true;
                  }
            }
         }
      }
}
}    2、有应用后打开，packageName=&#34;com.instagram.android&#34;
using (var jc = new AndroidJavaClass(&#34;com.unity3d.player.UnityPlayer&#34;))
{
using (var currentActivity = jc.GetStatic<AndroidJavaObject>(&#34;currentActivity&#34;))
{
      using (var packageManager = currentActivity.Call<AndroidJavaObject>(&#34;getPackageManager&#34;))
      {
         using (var intent = packageManager.Call<AndroidJavaObject>(&#34;getLaunchIntentForPackage&#34;, packageName))
         {
            if (null != intent)
            {
                  AndroidJavaClass intentClass = new AndroidJavaClass(&#34;android.content.Intent&#34;);
                  AndroidJavaObject intentObject = new AndroidJavaObject(&#34;android.content.Intent&#34;);
                  intentObject.Call<AndroidJavaObject>(&#34;setAction&#34;,
                     intentClass.GetStatic<string>(&#34;ACTION_VIEW&#34;));
                  AndroidJavaClass uriClass = new AndroidJavaClass(&#34;android.net.Uri&#34;); // 对应的安卓调用函数是Uri.parse()
                  AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>(&#34;parse&#34;,  urlScheme);
                  intentObject.Call<AndroidJavaObject>(&#34;setData&#34;, uriObject);
                  intentObject.Call<AndroidJavaObject>(&#34;setPackage&#34;,  packageName); // 记得要set package他才知道在哪里运行url sheme，否则url会从默认的浏览器里打开
                  currentActivity.Call(&#34;startActivity&#34;, intentObject);
            }
         }
      }
}
}
urlScheme获取，参考Instagram
      3、Instagram安装后未运行，跳转失败处理。manifest内添加包名
<queries>

<package android:name=&#34;com.instagram.android&#34; />
</queries>
