    After developing your first Android app successfully, you must learn how to upload it on Google Play Store. Right? Refer to our next section.

Upload Your App on Google Play Store

Thousands of Android apps get released every month via the Play Store. There are numerous benefits associated with publishing apps to app stores. It gives a boost to your featured app with the number of downloads, wide target audience/users reach, and ultimately leads to great profit.

So, let’s check all the steps to upload an Android app on Play Store. Just ensure you follow each step in chronological order to avoid errors.

  1. Google Play Developer Console

    Android developers submit an app to the Play Store through Developer Console, which is a kind of a backend controlling center. You will need to pay a one-time fee of $25 to open an account loaded with functions and control features.

    Additionally, you will be required to fill in all the information, such as your name and country details. It might take up to 48 hours to approve your account. After that, you can publish your Android app to the Play Store for free.

  2. Create Application

    Here are your next action points:
    Create Application

    • Go to the ‘All applications’ tab
    • Select ‘Create Application’
    • Set default language from the drop-down menu
    • Enter the title of your application
    • Now click on ‘Create’
  3. Store Listing

    As shown in the image, you will be required to fill in all the information and details about the app. Just ensure you use appropriate keywords related to your app because this will increase the chances for your app to show up in searches.

    Store Listing

    Here are the best practices that you need to consider while publishing your app-

    • Title
    • Short description
    • Full description
    • Screenshots of your app (JPEG or 24-bit PNG) (Min – 320px & Max – 3840px)
    • Hi-resolution icon (512 x 512) ((with alpha) 32-bit PNG)
    • Feature Graphic (1024 w x 500 h) (JPG or 24-bit PNG (no alpha))
    • Type of application
    • Category of your app
    • Rating of the content
    • Email of app developer or company
    • URL for the privacy policy
    • Use 2 – 8 images
  4. Upload App Bundles or APK To Play Store

    In this step, you will be required to use the files, such as App bundle or APK and sign the app release and upload them into your application. You can also refer to this blog on how to generate a signed APK.

    • Click on the ‘App Releases’ tab
    • Choose any one release 1) Internal Test, 2) Close Test, 3) Production Release, 4) Open Test
    • Select ‘Create Release’
    • Land on the New release to the production page
    • Choose to opt for the Play Store app signing on the app
    • Click on the ‘OPT-OUT’ option
    • Select ‘Browse files’ and upload apk to Play Store
    • Click on ‘Review’ to confirm the information
    • Press ‘Save’
  5. Time for Content Rating

    It is essential to rate the app. Otherwise, the app listed as ‘Unrated’ might get removed from the store.

    Time for Content Rating

    • Select ‘Content Rating’
    • Click on ‘Continue’ and type your email address
    • Press ‘Confirm’
    • Fill in the questionnaire for your app rating
    • Select the ‘Save Questionnaire’
    • Choose the ‘Calculate Rating’ option to see the app rating
    • Click on ‘Apply’
  6. Fix App Pricing and Distribution

    Please ensure that Google doesn’t allow anyone to convert free apps to paid apps. However, you can change the price of the app later. So, assign a price for your app wisely.

    • Go to the Pricing and Distribution tab
    • Choose ‘PAID’ or ‘FREE’
    • Select the countries where you want to publish your app
    • Select ‘Yes’ for Primary Child-Detected (app suited for children under the age of 13) or ‘No’
    • Select the options for allowing any ads
  7. Publish Your App

    Publish Your App

    • Go to the ‘App Releases’ tab
    • Select ‘Manage Production’ and ‘Edit Release’
    • Click on ‘Review’
    • Choose ‘Start rollout to production’
    • Select ‘Confirm’

    Confirming this means you have successfully published your app to the Play Store. Now, you have to wait for your app to get approval. Generally, it takes around 2 hours but can also take days for the same.
