Once we have created an account and have paid the $25, we are able to add and publish Android applications. We are only required to do some previous steps before actually publishing an Android application: prepare the store listing with all the screenshots, marketing material, and texts and promotional images, and upload the application binaries.
Our first step will be to add a new application to our account. We have to select the default language of the application, which will be the default language in which we will be editing our texts in Google Play and our application title.
If we have our APK ready, we can start by uploading it; otherwise, we can start by preparing the store listing.
