All applications

The All Apps section gives you a quick view of your app, and you can jump to the stats, reviews, and product details pages, or upload a new app.

Details of your account

Specify information about yourself or your company's developer profile on the Account Details page. This allows Google Play and your customers to recognize you. You can return to edit this information at any time and change your settings.

Your developer profile includes:

• Developer name-displayed on your Product Details page and elsewhere on Google Play.

• Contact information-for use by Google only, your customers do not see this information.

• The site url-is displayed on your Product Details page.

On the Account Details page, you can also add restricted access to marketers and other teams, sign up for a merchant account, or set up a Google Play license test account.

Associate your merchant account

If you want to sell an app or an in-app product, you can associate your Google wallet merchant account with the developer profile. Google Play uses the associated merchant account for financial and tax identification, as well as monthly sales payments.

Multiple user accounts

Set up user accounts for other team members to access different parts of the developer console.

The first registered account is the account owner and has full access to all parts of the console. Owners can add user accounts and manage console access.

For example, an owner can grant a user permission to publish and configure apps, but not to access financial reports. Now to learn how to set up multiple accounts.

Product Details

Use the developer console to set up the Product Details page . This is your app's home base in Google Play. This is the page where users see and learn about your app on their phone or on a webpage and download the app.

Upload custom branding, screens and videos to highlight the great features your app has. Provide localized instructions, add notes about the latest version, and more. You can update your product details at any time.

Uploading and instant Publishing

In the developer console, you can quickly upload and publish your ready-made Android app package files. Before publishing, the app is in draft state, and Google Play will give your Product Details page and app to the user when it's published-your app will appear on the Product Details page in a matter of hours instead of weeks.

After you publish your app, you can update it at any time: Change the pricing, configuration, and distribution options at any time, without updating your app's binaries.

When you add features or troubleshoot code issues, you can publish the updated binaries at any time. The new version is almost immediately available and will be notified to existing customers and updated for download. Users can also accept Automatic updates for your app and push and install updates as soon as you publish them. You can unpublish your app at any time.

Alpha and beta testing

Getting real feedback from users is always valuable, especially before publishing. Google Play makes it easy for you to distribute your pre-release app versions to alpha and beta test groups anywhere in the world.

In the APK section of the Google Play Developer console, you will find the Alpha test and beta test tabs. Here you can upload the APK files for each version of your app and define your tester list as a Google group or your Google + community. After you do this, you will receive a URL that can be forwarded to the tester, which the tester can select to join the test plan.

After the testers choose to join, they will go to the app's product page, and when they download the app, Google Play will send them alpha or beta versions as appropriate. By the way, if users happen to have joined your two test groups, Google Play is always sending them alpha Beta.

Note: Users cannot provide feedback and evaluation of the app's Alpha and beta versions. To collect feedback, you can use the Google Group or the Google + community, or set up an email address, or use your own website.

You can use these test plans to optimize your apps, help publish to new markets, and start building your own community. More information about using beta testing is also available in the release checklist and Localization checklist.

Phased release

You can also use the Production tab to publish your app in stages in the APK section of the Google Play Developer console. Here you can define the percentage of users who can download your app.

Staged release helps limit the impact of unexpected errors or server load, and allows you to measure user feedback with unbiased user sampling. During a phased release, users can rate and evaluate your app, so if you're hesitant, you can publish it to a smaller percentage of users first. Be sure to focus on any negative reviews and respond in a timely manner.

Note: Rollback is not supported due to application version control requirements for Android platforms. If you need to roll back, consider using the new version number before you publish the APK. However, this approach can only be used as a last resort, because users will not be able to access new features, and legacy apps may not be forward compatible with your server changes or data formats, so be sure to perform alpha and beta testing on updates.

Multiple APK support

In most cases, you only need to provide a single app package (APK), and this is often the simplest way to manage and maintain your app. However, if you need to provide different apk,google Play for different devices, the implementation method is provided.

multiple APK support allows you to create multiple application packages using the same package name, but OpenGL texture compression format, screen size support, or supported Android platform versions are different. Simply upload all Apk,google Play under individual product details to select the most appropriate file to provide to the user based on the features of the user's device.

You can also use the apk extension file option to upload up to two secondary downloads for each of the released apk (including multiple apk). Each extension file can be up to 2 GB and can contain any type of code or asset. Google Play hosts these files for free and downloads the files as part of a normal app installation.

Product Sales and Pricing

Gives you the tools to set prices for apps and in-app products. Your app can be downloaded for free or for a paid download, which requires payment to download.

• If you publish as a free app, you must always be free for the lifetime of the app . Free apps are available for all Google Play users to download.
• If published as a paid app, you can also change to free later. Paid apps can only be purchased and downloaded by a user who has registered a payment method on Google play.

Refer to the region that supports distributing your app to see a list of countries or regions where you can distribute or sell your app.

Whether it's for free or paid apps, you can also offer products and subscriptions within your app. Set prices separately for paid apps, in-app products, and subscriptions.

When users browse your app product pages, or start buying, Google Play displays the prices they charge to them in the local currency.

For each product, you first set the default price in your own currency. If you no longer set another price, Google Play automatically sets the local price for your app once a month based on the dollar price.

However, Google Play gives you full control over how your products are priced in each country. First, you can manually set a fixed local price that differs from the default price by using the auto-convert now price feature. You can then review these prices and set new prices for any country you need-the price per country is independent, so you can adjust one price without affecting other prices. For most countries, the price you set is the final price that is charged to the user, including the tax amount.

For more information about app pricing, see extending to new markets.

In-app Products

You can use in-app billing for Google Play to sell in-app products and subscriptions as a way to monetize your app. In-app products are a one-time purchase, and subscriptions are recurring monthly or yearly charges.

In the in- app product section of a specific published or draft APK, you can:

• Create product details for in-app products and subscriptions.
• Set the price.
• Publish products together with your app or undo obsolete products.

For more information on how to implement in-app billing, please refer to the in-app billing developer documentation. You can take advantage of in-app products by adding value, free add-on, and subscription-based monetization models

Distribution control

Manage which countries and regions your app will be distributed to. For some countries, you can choose your target carrier. You can also view a list of devices that your app is suitable for, based on any distribution rules declared in its manifest file.

Set Geographic targets

You can use the controls in the Google Play Developer console to easily manage your app's geographic distribution without changing your app's binaries. You can specify which countries and regions you want to distribute to, and even which carriers (in some countries).

When users visit the store, Google Play ensures that they are in one of your target countries to download your app. You can change your target country and carrier at any time, just save your changes in the Google Play developer console.

To help you sell to users around the world, you can localize your product details, including app details and instructions, and promote graphics, screens, and more.

Set Competency Goals

Google Play also allows you to control distribution based on the device features or capabilities your app relies on. Applications can define several dependencies in their manifest file, such as hardware capabilities, OpenGL texture compression formats, libraries, versions of the Android platform, and so on.

When you upload an app, Google Play reads these dependencies and sets any necessary distribution rules. For technical information on declaring dependent conditions, please read the filters on Google Play.

For precise control of distribution, Google Play allows you to see all of the devices that your app is eligible for depending on its dependencies, if any. In the Google Play Developer console, you can list supported devices and even exclude specific devices if needed.

User reviews and Crash reports

The user reviews section gives you access to an app's user reviews. You can filter reviews in a variety of ways to make it easier to find problems and to support your customers more effectively.

Google Play makes it easy for users to submit reviews of apps that benefit other users. Reviews provide you with details of availability feedback, support requests, and important functional issues that come directly from your customers.

Use crash reports to debug and improve your app. You can see crash reports that are automatically submitted via Android devices that contain stack traces and other data.

Apply Statistics Information

App Statistics page : shows you various statistics about the installation performance of an app.
