Another Doze Edge Case: Foreground vs. Foreground
Petr Nalevka has done a lot of work trying to make sense of some odd Doze mode behaviors on Android 6.0. In particular, he has nailed down one source of problems when trying to use a foreground service to bypass Doze mode.
A foreground service with a partial
WakeLock is supposed to block
Doze mode, presumably with an eye towards music players and the like.
However, Mr. Nalevka
that if the process with the
foreground service also has the foreground activity, Doze mode
takes over again.
Dianne Hackborn’s recommended workaround is to split the foreground service out into a separate process. Since there doesn’t seem to be a way to link to specific G+ comments, you’ll need to scroll way down the comments list on this post to get to their exchange.
