Android: Customizing recent apps thumbnail (screenshot by default) -


the app i'm working on shows sensitive information must not shown on "recent tasks" screen when stopping app pressing home button.

i'd blur sensitive data in screenshot or show app logo instead.

i aware of following approaches don't fit requirements:

and there workarounds tried out didn't work hoped:

  • start new activity shows app logo in onpause it's screenshot shown instead of actual activitie's one. new activity takes long open , disrupts user experience.
  • set activitie's content view image of app logo in onpause. seemed great solution me. unfortunately, screenshot recent tasks screen taken @ unspecified time. during testing app logo appears before app closed when pressing 'home' resulting screenshot shows activity short time before that.
  • removing sensitive data widgets (e.g. textview.settext("")) has same problem of screenshot timing mentioned.

any alternative ideas or solutions listed workarounds?
