I'm new to Android app development, and I think it's cool to push my apps with a kind of Intro as soon as they run.
I was researching on what I came to this library: link
It turns out, however, that I can not add it to the project. I've already tried declaring this library as a dependency in my build.grad, as the developer explains, but I could not get the library to be downloaded in my project in Android Studio.
Can anyone help me by taking a step-by-step or do you have a more appropriate suggestion to accomplish what I'm asking?
Thank you =)
