UnsupportedOperationException at com.adjust.sdk.Util.dateFormat(Util.java:88) in Android OS 5.x

Hi,

We use the Android Adjust SDK 4.7.0 in our app and we noticed a crash on Android 5.x devices.
Here is the stack trace.

Thanks

Hi @jmehtaebates

Thank you for this report. Can you please tell me if this is something which you are able to reproduce?

Hi @uerceg

There aren't any specific reproducing steps. Here is some additional info which might help

In last 30 days, we saw 438 users affected by this with a total of 458 crashes
95% of these were seen on devices running 5.x android version
87% of the total happened on samsung devices

Hi @jmehtaebates.

I've tried to replicate in an emulated device with Android 5.0.1 by initialising and using the format function of SimpleDateFormat dozen of thousands of times from different threads without success.

It seems that Android 5.0 had that private function java.util.GregorianCalendar.julianError in their code.
The code in question does not seem that could do anything that would cause that exception, but a search of UnsupportedOperationException samsung online reveals that this would not be the first issue for that manufacturer.
Current version of Android SDK do not contain the same private function, so it would not happen anymore.
What we can do is catch the unexpected exception explicitly in that section in a future version.
In the meanwhile, I would recommend that you update to the latest version of our sdk that catches any exception that occurs in the background. It might not still enable the sdk to work for those situations, but it shouldn't crash it.

Thank you @nonelse

I will let my team know as well.
