ARCore: arore-preview.apk (= Tango Core app) required to run the ARCore app?

Question

I would like to develop an application using ARCore. I have a few questions:

• Do I need to install arcore-preview.apk to run this ARCore application?
• Why does the arcore-preview.apk file appear with the name "Tango Core" in the application list of my device?
• Will Android OS directly include the ARCore SDK (Tango Core?) In the future?
• Will all devices be compatible with ARCore? (not just S8 and several devices ...)

Thank!
