Cannot find com.intuit.utils.OauthHelper class for Android application - quickbooks

Question

I want to integrate QuickBooks api into our android application.
Below link is for Java Web Application but I want to this OauthHelper class in my android application.
https://github.com/IntuitDeveloperRelations/QuickbooksV3API-Java/blob/master/QuickbooksV3API/src/main/java/com/intuit/utils/OauthHelper.java
I also saw developer site of Intuit but it does not help,
https://intuitpartnerplatform.lc.intuit.com/questions/825445-can-t-find-com-intuit-ia-connection-oauthhelper-class
Is there is a new way to do it or any latest jar file which contain OauthHelper class?
