I'm hoping somebody can guide me through the process of getting my game onto the Play Store. It's my first solo attempt at releasing an app, so I'm a bit uncertain which path to take. I'm working my way through the Play and Android Developer Guides looking for solutions but there's quite a lot of options to choose from.
This is the game in question: Angle Fu
It's a bit of fun to help kids learn different angles - nothing fancy, which I figured would make it a good test-run title.
Here's where I am so far:
I've tested the debug apk to check that the game is performing as expected.
I've generated an unsigned release apk using C3's build service.
I have a keystore, generated previously when learning to use cocoon.io.
I have a Google Play Developer account.
I'm intending to make it free, with no ads or IAPs.
The questions I have are:
What is the best/easiest way to sign the apk?
Should I be using Android Studio during the process and if so should I use the C3 Android Studio export option?
Can I reuse my existing keystore or should I create a new one?
Should I use Google Play App Signing?
What assets need to be prepared in advance (screenshots, icons, videos etc)?
What can I expect after publishing (e.g. wait before appearing in the Play Store)?
What if I wanted to release a paid app?
Is there anything else I'm missing?
Many thanks in advance to anyone who can offer advice for any part of this or point me in the direction of useful resources.
