caching - Are auto-verified links cached in Android M? -


i'm working on running tests see how verified links system works android m , ran interesting outcome. usual flow this:

  • install app
  • get ${host}/.well-known/statements.json fired
  • if approved (server up, key valid, etc.), verified links deep link app

when server down, see this

  • install app
  • get ${host}/.well-known/statements.json fired
  • not approved, links show pop-up
  • uninstall & reinstall app
  • get ${host}/.well-known/statements.json fired

however, if server goes down after initial verification, see interesting

  • install app
  • get ${host}/.well-known/statements.json fired
  • approved, deep links
  • turn off server
  • uninstall app & reinstall app
  • no network call made

if wait amount of time before reinstalling, network call made , things act normal. seems autoverify data and/or app -> link data being cached somewhere isn't destroyed app uninstall.

  • is behavior expected?
  • why happen, versus hitting server?
  • where cached, if not app?
