After creating your Google Developer Account, setting it up, and sharing the access with Uscreen, there are just a couple more steps required: Create Service Account and share a JSON key with us.

After doing that your account setup is complete and we can get started with your Android and AndroidTV apps development!

Create Google Service Account and JSON key

A Service Account is a special type of Google account intended to represent a user that needs to authenticate and be authorized to access data in Google APIs.

Uscreen developers need this access in order to upload Android and AndroidTV apps to your Google account.

The Service Account login is made through a file in JSON format that will be used as the key to authenticate. We’ll need the account owner to create the Service Account and generate the JSON key and share it with Uscreen.

  1. Start from your Google Play Console, and make sure you’re logged in with the account owner credentials.

  2. On the Menu click on API access, under Setup:

  3. If you don’t have a project, click on Choose a project to link

    • On the modal window, you’ll need to agree with the Terms of Service.

  4. Click on Create new project and click on Link project:

  5. After the project has been created and linked, it will look like this:

    Google Cloud Project linked on Google Play Console

  6. Now, on this page scroll down to the Service Accounts section and click on the Create Service account link, it’s located in the top-right, aside from the 'Service accounts' title:

    Create Service account

  7. It will open a modal with the instructions to create a new Service Account. Don’t close this popup! Instead, click on the Google Cloud Platform link:

    Google cloud platform link

  8. It will open Google Cloud Platform in another tab of your browser. You should be placed under the Service accounts section. If so, click on Create Service Account at the top:

    NOTE: If Google Cloud Platform opens and you’re not able to see the option to create a Service Account, or if the screen looks anything different than the screenshot above, please make sure you’re logged with the same user on both tabs (Google Play Console and Google Cloud Platform).

    • You can check the account user profile logged in each tab by clicking in the profile icon at the top-right corner of each page.

    • If you need assistance, please send an email to and we’ll help you.

  9. Fill the form to create the new service account
    - Service account name: You can use ‘Uscreen’ or ‘UscreenOTT’
    - Click ‘Create’

  10. Grant service account access to the project

    • In the Role dropdown, select Owner (this option will appear on the right side)

    • Then click Continue

  11. In the third step you’ll generate and download the JSON key:

    • Click on ‘Add Key’ and ‘Create new Key’

    • Then select ‘JSON’ and click on ‘Create’.
      The download will start automatically:

    • Save this JSON file and send it by email to

    Now that you have created the Service Account and shared the JSON key with us, there’s just one more step required: Grant access to this service account on Google Play Console.

    Grant access to the Service Account in Google Play Console

    If you followed all the steps above, you’ll probably still have Google Play Console open in a tab in your browser.

    If that’s not the case, no problem, You can enter on Google Play Console and follow the steps below:

    1. Click on ‘API access’ on the menu (refresh this page if your tab is still there)

    2. Scroll down to ‘Service accounts’

    • The newly created Service Account must be listed there (

    • Click on the Grant access link on the right side

    • In the ‘App access’, under ‘Account Permissions’ select ‘Admin (all permissions’) and click on ‘Invite user’, and ‘Send invite’

    3. If you want to review and make sure your Service Account was created correctly and the access was shared, just follow the steps below:

    • Click on Users and Permissions in the Menu

    • Check your user's list. There should be at least 2 user accounts:


      - uscreen@api-xxxxx.ia

    • If you can both accounts are listed, it means you have successfully shared the access with the Uscreen account and created a Service Account. Remember to share the JSON file with us.

Congratulations! You have successfully completed all the steps required to set up your Google Developer account and shared access to your account with Uscreen!
