It's necessary to register for a Google Developer account in order to upload Android apps. Your Developer account is where you'll submit, as well as manage your apps. It costs a one-time fee of $25.
We recommend setting up a second Google account for this purpose, so you can separate it from your other Google services (Gmail, Google Drive, Google+, etc.) if you already have a personal account.
How-To:
1. Register for an Android Develop account here. You'll need to log into the Google account you'd like to use.
2. You'll be taken through a 4-step registration process. Check the agreement box and click Continue to payment.
3. Next, a pop-up window will prompt you to input your billing information. After you've filled it out, click Pay.
4. Finally, complete your account info. You should receive a confirmation email after you've finished!
