Android 12: Application stops sending data to server after ~30 mins

[adamdewey]

Describe the bug

When using Android 12 the application stops sending data to the server after roughly 30 mins.

If the application is restarted the missing data is then sent to the server.

This causes issues for all integration pieces:

• Desktop alerts
• Dashboard
• Telegram alerts

To Reproduce Steps to reproduce the behavior:

1. Start application recording 3 sensors on Android 12
2. Monitor integration with server

Expected behavior Data to be sent continuously from application to server.

Smartphone (please complete the following information):

• Device: Samsung Tab A7
• OS: Android 12 (SP1A.210812.016.T500XXS4CVJ1)
• ColdChain Version 0.5.0
• Sensors: Blue Maestro (blue Tempo Disc 3)

Additional context

• 2 of the sensors are set to log every 2 mins
• 1 of the sensors is set to log every 1 min

unable to replicate so far. I have a release build running on a samsung android 12 and it hasn't stopped yet

[adamdewey]

@mark-prins - strange, is it 0.5.0 downloaded from the releases page?

[mark-prins]

I've made a new build, which has some logging around the sync calls.. so technically no. realistically though, it's the 5.0 branch and a release build, so is almost the same thing. I am running against a local mSupply instance though, so will change that and use a hosted server instead. Perhaps network performance is a problem?

[mark-prins]

@adamdewey which version of mSupply are you using? because I'm running locally, I'm on the sync-v5 branch. I should test with the version you are running. And are you running it locally, or is it a cloud server?

And yeah, it's a cloud server - it's the vaccine demo server. Details are under 'Vaccine and Cold Chain - Stable Demo Server' in BW :)

Interestingly I haven't seen this again recently - seems to be running fine on Android 12.

Hmm, will close for now!
