Appium Android Clients Test cases failing



I have tried both Java and C# client for appium. In both, some of the test cases are failing. Ex: swipe in c# and scroll in java. I am using the latest appium code and latest client codes.

I am using Android API level 17 emulator. As per the appium doc, API 18/19 is needed for some features, but I don’t know what are those. Is it because of this that these test cases checked in github are failing?
