So I was going to do a demo. And I figured, since my stuff melts down into slag on a regular basis, I'd install all the Tango demo apps.
Bad idea When Tango went to reboot, it went through the normal screen animations, but it hung on the animated tango spinner for over an hour - something was making it hiccup, the spinner was jerky, freezing for a second on pretty much every face. Did a full data purge, let teh goog reload everything, problem came right back -

Sorry cap'n, she canna boot.

Did it again, told play to keeps its opinions to itself and not restore anything - just put the explorer and area manager on manually - great joy, they work fine, things are back to as normal as they get

So, I have a suspicion that some of the demos may work on the phone but lead to some nastiness on the tablet - has anyone else got any experience with or knowledge about this ?

  • Have you tried to force shut down and start again the device? and do you remember which app you installed caused this? – xuguo Jan 21 '15 at 22:50
  • If I knew which app I would say - I can't fund researching other bad apps, mine is bad enough to eat all my resources :-) I agree it would be nice to winnow it down, I can say it is not the Tango Explorer, the Area Manager, or the Room Explorer - its one of the others - I can say I know I pulled them all down. – Mark Mullin Jan 22 '15 at 01:03
  • And yes, I forced a shutdown - hey, this is Tango - it used to be that half my attempts to do pointclouds in java ended in a forced shutdown hoping that would fix lack of point cloud data - and then I began to understand poses with respect to the two basis, the startup inertial frame and the area definition frame and pointclouds are far more friendly :-) – Mark Mullin Jan 22 '15 at 01:05

To solve the hanging on start up issue, you could hold the power button for 10 seconds to force shut down the device and restart it after.

  • Oh, no - trust me - did that - it took holding power, both volume down, going to the magic menu, blowing away ALL the user data, and then preventing the evil little buggers from coming back down - anything else and it hung post the project tango splash, where the logo does its final spinning and you can see it pause very briefly - in this case it paused not briefly on every damn face and this was allowed to go on for hours (once) I wonder if it was the debugger addin ? But trust me, it was stuck somewhere bad – Mark Mullin Jan 22 '15 at 01:01
