Android的Google登录适用于您的应用的身份验证。它为你提供了强大的功能，所以你不必担心认证实现。不过，如果您打算拨打Gmail API，例如 Users.messages.list ，Google Sign-in还不够。组件如授权和范围被添加到图片中。
因此，对于您的情况，您需要从 Gmail Android快速入门，因为它详细说明了成功拨打电话所需的步骤。

I am trying to access sent mails with gmail on an android app. I tried to follow this but I don't understand how to get the Gmail API instance.

I also found two ways to connect: the gmail API one and Google Sign-In.

What's the difference between them and which one should I use ? Is this the way to access user's mails with my app ?

Google Sign-in for Android is good for authentication purposes for your app. It does the heavy-lifting for you so you don't have to worry about authentication implementations.

However, if you intend to make calls to Gmail APIs like the Users.messages.list you've mentioned, Google Sign-in will not be enough. Components like authorization and scopes are added to the picture. So in your case, you need to start with the Gmail Android Quickstart as it details the steps you need to make successful calls.
