I am trying to download new updated apk from my website if available and then install it using Unity to override my already installed game.
I can download apk in memory card of user using following code .

private IEnumerator TestDownload()
     {
         WWW www = new WWW("http://192.168.1.6/file_drop/app.apk");
         //yield return www;
             
         while (!www.isDone) {
             progress = "downloaded " + (www.progress*100).ToString() + "%...";
             yield return null;
         }
             
         string fullPath = Application.persistentDataPath + "/app.apk";
         File.WriteAllBytes (fullPath, www.bytes);
             
         
         
 ...
 }

Now is there anyway to run this downloaded file form unity script so it start installing
?

Not an answer and I honestly don’t know the answer to this question, but I would assume there is not as that would be a HUMONGOUS security risk… Imagine installing a game that can download whatever apk it wants, virus / malware or whatever and just install it itself? I’m sure there are ways to do this anyways, but… As a user, if an app had that ability and I knew about it, it would never get installed on my devices. Going to follow this just to find out if anyone has an answer…
