Support for latest API level

[ebghrimtech]

Hello,

We are currently using your library in one of our applications. Actually we need a favour from your side. According to the Google Play Policy, all apps have to provide support for at least API level 26. It seems like yours is not as per the new google play policy. We are targeting API level 28. So can you please provide us support for API level 28 in your current repository?

Please check out the Android official docs. We just want to make sure that all the libraries support at least API level 26 and we are targeting API level 28. Please update as soon as possible.
