Expected behavior

API should not fail

Actual behavior

API is failing. It seems that while parsing the date there is an exception which is apparent from the line: Caused by java.lang.IllegalArgumentException: Unknown pattern** **character 'X'

Steps to reproduce the behavior

Query the OneDriveGraphServiceClient.me().drive().root().children() api with Android OS version 5

Hey @atulgpt
Thanks for reaching out.
That's because the java API version available on such devices doesn't support parsing the date format returned by Microsoft Graph.
You can add support for it using desugaring, see my comment on a similar issue #286 (comment)

[atulgpt]

Hi @baywet is there any other way/hack to fix the issue. Adding desugaring lib add size to the app as well as will have major testing impact? I am assuming that you are referring to coreLibraryDesugaring option in build.gradle

[baywet]

Not that I know off. The alternative would be for us to test the java API version and fallback on a supported pattern. But that would introduce another issue with time zones and dates being inaccurate.

[atulgpt]

Hi @baywet only usage of 'X' is not supported in pre-android version and I tried finding its usage but couldn't understand much. Not sure if this will lead to time zone errors or wrong time being shown. Its a big limitation for every client using this recommended SDK. The old SDK(Android SDK) was deprecated and in newer one we are getting issues with latest Java api usage and we also have to add coreLibraryDesugaring which also increases size and testing impact.
