Hi!
I use screenlets (usually AssetListScreenlet or WebContentDisplayScreenlet) to display contents, but sometimes it's crashing with this error:

Hey, this should be fixed with the 7.2.2 version of the liferay-mobile-sdk-core

Hey,Are you using liferay-screens in the same project?  I think it is using a past version imported for liferay-screensCan you check the version used executing 
./gradlew app:dependencies
app is the name of the gradle project, yours can be different
I hope it helps emoticon

HeyIf you have the 7.2.2 version it shouldn't be possible to get that error because we didn't even use a reentrantLock in that class, can you check in your project the class OAuth2AuthenticationRefreshHandler and let me know if this is using the lock?
Thanks

As you've seen above, I use 7.2.2. I'd like to believe that it shouldn't be possible, but this error is created by endusers mobile.  After refreshing to 7.2.2, the error occurrence is less than before in 7.2.1.I don't know how can I check client's lock.I trying to refresh the application one more time.
