Answer 1

In terms of the time gap, most likely, you are experiencing Doze mode on Android 6.0+ devices, or the equivalent offered by some manufacturers on older devices (e.g., SONY's STAMINA mode). Other than adding your app to the appropriate whitelist (e.g., for Doze, Settings > Apps > (gear icon) > Special access > Battery optimization), there is very little that you can do.

You are welcome to switch to setExactAndAllowWhileIdle() on API Level 23+ devices, however:

• You will not get control every minute (I think it is limited to every 9 minutes)

• You will not have Internet access when you do get control (which presumably is required for whatever you are trying to do for real)

• This will not help for manufacturer-specific pre-6.0 devices (since that method does not exist)

Overall, designing your app to deal with Doze mode, and not assume that it will get control much in the background, is a more reliable approach.
