Android Project

A sample app for online and offline

Add totoframework library to project

First, create the same project as the one we created in the Android Native.
Download oztoto80_android_version.number.tar.gz from 👉 Product Downloads
Get the oztotoframework_android.jar and add it to the libs folder. Of clause, you have to set library dependencies too.
