Based on the Google Play game services samples, particularly TypeANumber, from (https://github.com/playgameservices/android-basic-samples), I was wondering if it's preferred to implement all of the activities as fragments (other than MainActivity that's responsible for instantiating and connecting to GoogleApiClient) if I wanted my app to be connected to the services the whole time.
Because, I already developed a game app that consists of activities that transitions to each other by using using Bundles and Intents, and now I am just starting to figure out how to implement Google Play game services to my game. I already read the tutorials and whatnot, but I just want to know if it's recommended to use fragments for the other activities.
In other words, you're pretty much just asking which is better to use between Activity and Fragment. It technically still depends on you are aiming for. Looked around the community for a while and found these posts where the answers are very much detailed:
Dilemma: when to use Fragments vs Activities:
Why fragments, and when to use fragments instead of activities?
On a simpler note, I prefer to use Fragment when re-usability is needed.
