What are the limits placed on location gathering for apps running in the background on Android O devices?

Question

I realize O is in developer preview at this point, but there are significant changes to background location gathering. What are they?

Answer 1

The following points summarize the limits placed on location gathering on apps running on O devices:

• As a starting point, background apps will receive location updates only a few times each hour (the location update interval may be adjusted in the future based on system impact and feedback from developers).

• Foreground apps are not affected by these limits.

• These background limits apply to all apps running on an O device, regardless of the target SDK.

• Apps targeting O are further subject to limits on services started in the background. For this reason, apps targeting O should not use PendingIntent.getService() when requesting location updates. Instead, they should use PendingIntent.getBroadcast() and register a BroadcastReceiver in the manifest (apps targeting N or lower may use either PendingIntent.getService() or PendingIntent.getBroadcast()).
