Question

I m new to Android programming and I have been trying to decide on the best approach for polling a device for long lat Originally I was going to have this in a background service but having read that you can only really poll once in a 15 minute time frame I have since abandoned that I have read that AlarmManager can be used however I feel like this to isn t suitable I have been looking into Foreground Services and they seem OK however Whats my best approach if I want to run a task in a foreground service say every 10 seconds is a foreground service even the right way to go

`WorkManager` could be one of the options for scheduling tasks

Alexander · Answer

From memory `WorkManager` is also bounded by the 15 min cap or am i getting confused

Makes sense to me otherwise apps would drain battery like crazy

Alexander · Answer

Sure it makes sense but how do usual Location apps work then say a company like Fitbit who plot your entire day on a map

Kirill Zhukov · Answer

They probably use wearables to track data and then sync to the app No clue

Kirill Zhukov · Answer

Did you check this one out yet

Alexander · Answer

Yes so they recommend taking your service to the foreground which I have started to look at However once in the foreground Im unsure on the best way to orchestrate the repeated task getting long lat

Kirill Zhukov · Answer

I have 0 experience with location APIs though I m not surprised about these restrictions

Alexander · Answer

I have also looked at `PeriodicWorkRequestBuilder` but again this can only perform tasks every 15 mins

Kirill Zhukov · Answer

Even for regular background tasks you can t completely trust OS with execution and timing of these tasks they can get deferred or even cancelled

Kirill Zhukov · Answer

Say if your phone enters doze mode tasks are executed only during execution window every now and then

Saves battery big time

Alexander · Answer

So how do location based apps get around this then

Alexander · Answer

I will read into that

Kirill Zhukov · Answer

My coworker actually did a good talk on this stuff a while back

Kirill Zhukov · Answer

Alexander · Answer

OKay cool will watch that

Alexander · Answer

I think Im going to google around and look at say a foreground service that toasts the time every 10 seocnds then work back from there

Kirill Zhukov · Answer

Apps have to follow these restrictions even Google maps from what I can tell

Kirill Zhukov · Answer

If you ever shared your location in Google maps someone you ll see that you are not getting actual live location if their phone is on standby

Kirill Zhukov · Answer

It could be deferred by hours

Kirill Zhukov · Answer

From my experience

Alexander · Answer

There has to be a way stuck out tongue

Kirill Zhukov · Answer

I doubt stock Android would let you do that

Kirill Zhukov · Answer

It s bad for battery and not good privacy wise in your specific case

Vineeth P C · Answer

Can t we use push notification to make the app report the location

Alexander · Answer

I mean i could look at streams in Kafka maybe

Alexander · Answer

Or maybe a rest endpoint webhook design

Kirill Zhukov · Answer

Not sure how that will help you get around the restriction for background task

Kirill Zhukov · Answer

Not very experienced in that area either though

Alexander · Answer

No if we abandoned the background task

Alexander · Answer

Kirill Zhukov · Answer

I m seeing fused location API being recommend over foreground service for location tracking

Kirill Zhukov · Answer

Alexander · Answer

Yes I have an implementation of FusedLocationAPIClient

Alexander · Answer

Ahh i didnt realise it can give bundled location updates in intervals this could be good
