Does anyone know QuickInstall's app ID?

Hi guys,

I’m trying to make a manager app for Nreal glasses’ apps with Unity. I got some issues about the QuickInstall feature. My questions are:

  1. Does anyone know QuickInstall’s app ID?
  2. How can we implement auto-installation feature without Android’s install screen (refere to attached image) as the QuickInstall realizes?

About #2, I don’t believe it is possible to skip the install screen and install the apk unless a computing unit is rooted. Actually, there is “AutoInstaller” mod for Xposed which needs the root.

If you have any clue, it will be helpful for me.
