While there was never any mention of the recently-reported (and rare) Skype messaging bug actually affecting Android, anyone who had any slight concerns can rest easy. While a fix is being rolled out, Skype has officially stated that Android users on Skype version 2.8 are OK.
In an official statement on their blog, alongside announcing a fix for all affected versions, they had the following to say specifically mentioning Android, and iOS versions of the app --
During further investigation, we confirmed that not all Skype products were affected by this error as originally reported. We can assure that users of Skype 5.9 for Windows, Skype 2.8 for Android and Skype 4.0 for IOS have not been affected.
So, while all is OK, if for some reason you've avoided updating to version 2.8, it's probably worth doing so to ensure you remain bug-free.
