Hi, Jonas and Jan, Good Day!
Thanks a lot for this discussion thread. This is quite related to what I am working on now. So far I am applying a wakelock for screen with camera function turned on; however, my ultimate ideal solution is to have vibration active while screen is still off in the scenario that it's at certain timing but not yet reached certain point on GPS... I am still looking for better solution or potential ways, hopefully it not a complete out-of-the-question.. let's keep this discussion updated if there is new ideas! :) BR, Chelsea On Mon, Jul 14, 2014 at 6:14 AM, Jonas Sicking <jo...@sicking.cc> wrote: > > On Jul 13, 2014 8:59 AM, "Jan Jongboom" <janjongb...@gmail.com> wrote: > > > Can I ask what type of thing you are trying to build? > > > > > > We do actually have a permission for "ability to use sensor API even > in background".
