@pragyagrawal can you update to the latest SDK? We are on 3.1 now and releasing 3.2 soon.

@akhilmohan , thank you for reporting this. A ANR is not a crash. The app is not responding. In this case, if there is a problem with your data connection and datafile polling is enabled, it could be that the data file service was waiting to long for the cdn response. Right now, our timeout is 5 seconds. Can you tell us anything else about the issue such as what other threads might be doing at the time or the state of your app at the time? Thank you again.
I would also recommend updating to the latest version of the SDK.

We also have bunch of ANR's reported. Looks all are android 6.0 version.
SDK version: 2.1.2
Play console shows me this warning:
The "main" (tid=1) thread is in suspended state. This is likely due to garbage collection.

@thomaszurkan-optimizely I'm having issues with a different looking ANR log for DatafileService. I've run it across Android 8, 9, and 10 with the same result. The app stalls out on an ANR when the app boots up while the phone is in Airplane mode.
To reproduce:
- Put phone into Airplane mode
- Run app that has Optimizely Android SDK 3.2.1

@thomaszurkan-optimizely we are experiencing these ANRs with SDK 3.2.1 in our app. I noticed that the linked fix #295 for this will only modify the JobService scheduling on Oreo and later devices, not those using AlarmManager (see ServiceScheduler.schedule())
We have only started seeing these ANRs since we enabled datafile polling recently. It appears that on devices < Oreo our app process will be restarted every datafile polling period, even if the app has been terminated by the OS. There are some rare cases where our app will ANR during the initialisation of the app, and it seems that the frequency of these ANRs has increased because the datafile service is being triggered by AlarmManager, which is starting the app in the background.

@fingertricks we believe these should be completely cleared up with the latest release 3.5.2.
