Hi,
For future reference. On Android you can run this code directly from c#

Usage:

if(checkPackageAppIsPresent("com.facebook.katana"))
{
//your code if facebook was found
}

Method:

private bool checkPackageAppIsPresent(string package)
{
	AndroidJavaClass up = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
	AndroidJavaObject ca = up.GetStatic<AndroidJavaObject>("currentActivity");
	AndroidJavaObject packageManager = ca.Call<AndroidJavaObject>("getPackageManager");

	//take the list of all packages on the device
	AndroidJavaObject appList = packageManager.Call<AndroidJavaObject>("getInstalledPackages", 0);
	int num = appList.Call<int>("size");
	for (int i = 0; i < num; i++)
	{
		AndroidJavaObject appInfo = appList.Call<AndroidJavaObject>("get", i);
		string packageNew = appInfo.Get<string>("packageName");
		if (packageNew.CompareTo(package) == 0)
		{
			return true;
		}
	}
	return false;
}

There is no direct way to do it for Ios or Android. You have to write native function . It is explained here better.
IOS

Android

Etcectra Plugin has a method applicationCanOpenUrl which you can use .
