1. Prerequisites for Publishing an Android App

Before you begin the process of submitting your app to the Google Play Store, there are a few prerequisites you need to meet:

Functional and Bug-Free App: Ensure your app works as intended and is free from critical bugs. Test it thoroughly on various Android devices and versions.
App Versioning: Make sure your app’s version code and version name are updated. The version code is an integer value that must increase with each new version. The version name is a string that users see in the Play Store.
Google Play Developer Account: To publish apps on the Play Store, you need to have a Google Play Developer Account. A $25 one-time payment is needed for this.

Legal Compliance: Ensure that your app complies with Google Play’s policies, including privacy laws and terms of service. Your app must have a privacy policy if it gathers user information.
App Icon and Screenshots: Prepare assets like an app icon, promotional images, and screenshots of your app in use. These will appear on the Play Store listing for your app.

2. Step 1: Get Your Android App Ready for Publication

Before publishing your app, it’s crucial to ensure that it’s ready for the Play Store. Follow these steps to prepare:

Remove Debug Code: Make sure that all debug code and logging statements (e.g., Log.d()) are removed. These can slow down the app and expose sensitive information.
Minify Your Code (Optional): Use ProGuard or R8 (the new default in Android) to shrink your app’s code and remove unused classes. This will reduce the size of your APK or app bundle and make the app more efficient.
Testing: Test your app on real devices and use tools like Android’s adb (Android Debug Bridge) for debugging. For real-time crash reporting, think about utilizing Firebase Crashlytics.
App Permissions: Ensure that your app only requests permissions that are absolutely necessary. Google's Play Store policies are stringent when it comes to asking for extra permissions.

3. Step 2: Create a Developer Account

You must have a Google Play Developer account in order to publish an Android app on Google Play. Here's how to create one:

Using your Google account, log in to the Google Play Console.
Agree to the Google Play Developer distribution agreement.
Pay a one-time registration fee of $25. To develop and maintain your apps on the Google Play Store, you must pay this charge.
Complete your developer profile by adding details like your name, address, and phone number. This will be visible to users.

Once your account is set up, you’re ready to start publishing apps.

4. Step 3: Create an account on the Google Play Console

The Google Play Console is the dashboard where you’ll manage your app's submission, track performance, and interact with users. Here's how to set it up:

Log in to the Google Play Console: After creating your developer account, log into the Google Play Console using your Google credentials.
Create a New App: Select “Create Application” from the left menu.
Choose the Default Language: Select the language that will be displayed in your app’s Play Store listing.
Enter Your App Title: This is the name that users will see on the Play Store.
Complete Your App’s Details: You’ll be asked to provide a description of your app, categorization (e.g., education, games), and tags.

5. Step 4: Create an App Bundle or Signed APK

For security reasons, Android requires your app to be signed before publishing it. You’ll need to create a signed APK (Android Package) or App Bundle (AAB).

Here’s how to sign your APK:

Create a Keystore: Open Android Studio, navigate to Build > Generate Signed Bundle / APK. Android Studio will ask you to build a keystore if you haven't already.
Generate the Signed APK: After selecting your keystore, choose whether to generate an APK or an App Bundle. App Bundles are now preferred for new apps.
Build the APK: After selecting the build variant (usually release), Android Studio will generate the APK or AAB.

Remember, once your app is signed, you cannot change the keystore. Keep it safe to avoid issues with updates.

6. Step 5: Optimize Your App’s Listing

Your app’s Google Play Store listing plays a significant role in attracting users. Here’s how to optimize it:

App Title and Description: Use clear, descriptive language in the title and description. Be concise, but include relevant keywords that users may search for. The title should also be catchy to grab attention.
App Icon: Your icon should be unique, simple, and visually appealing. It’s the first thing users see, so make sure it stands out.
Screenshots: Provide high-quality screenshots showing key features of your app. Screenshots can include text overlays explaining functionality.
Feature Graphic: Include a promotional graphic (1024 x 500 pixels) to highlight your app’s main features.
Privacy Policy: If your app collects personal data, include a link to your privacy policy, as it’s a requirement by Google Play.

7. Step 6: Upload Your App to Google Play

Once your app is ready and your listing is optimized, you can upload your APK or App Bundle to the Google Play Console.

Choose your app in the Google Play Console, then go to the Release management area.

Click on App releases and select either Production, Beta, or Alpha depending on which phase you want your app to be in.
Upload your APK or App Bundle and fill out the necessary release notes. Provide an overview of the new features or modifications in this version.
Review and confirm the details of your release.

8. Step 7: Set Pricing and Distribution Preferences

You may publish your software to several nations and areas via Google Play. You also need to set your app’s pricing model. Here’s how:

Pricing: Choose whether your app will be free or paid. You cannot change a paid app to a free one after it’s published, but you can do the opposite.
Distribution: Decide which nations you would like your app to be accessible in.

9. Step 8: Submit and Closed Test for 14 days

After uploading your app and setting your preferences, the next step is to submit your app for a closed test:

A closed test with at least 20 testers who must opt-in for 14 days in a row is required by the present policy. This presents a problem for independent developers, particularly those creating feature-light apps.

Here are some steps to make a closed test:

Creating Closed Testing
Setup the Closed Testing Track
Add Testers to Test Your App
Create New Release
License Testing

You can apply for production access after fulfilling the conditions for closed testing. Simply click Apply for production on your Dashboard. After that, you have to respond to questions regarding your app, your closed test, and its production readiness.

If your app is approved, it will go live on the Google Play Store. If rejected, Google will provide feedback explaining why it didn’t meet their policies.

Once your app is live, you can start tracking its performance through the Google Play Console. You’ll receive insights into downloads, ratings, reviews, and crash reports. Use this data to make improvements and push out updates.

Additionally, engage with users by responding to their reviews, fixing bugs, and rolling out new features based on feedback.

Publishing your first Android app on Google Play is an exciting achievement. By following these steps, you’ll be able to navigate the entire process from preparing your app for release to submitting it to the Play Store. Remember to continually monitor your app’s performance and make updates as necessary. Good luck with your Android development journey!

Flutter vs React Native: A Developer’s Perspective

Flutter vs React Native React Native by Facebook and Flutter by Google – two hot cross-platform app development technologies creating a buzz. during this post, we'll compare both of them intimately from a developer’s perspective. Due to the growing popularity of mobile apps, almost every company needs a mobile app or apps to stay competitive within the market. And what's more, companies are trying to find an choice to build mobile apps, especially for iOS and Android, with faster speed and fewer resources. Apple and Google have provided native tools and technologies to create apps. iOS app developers can build apps using Xcode and Swift, while Android developers use Android Studio and Kotlin/Java. However, this needs engineers to find out two completely different sets of technologies. As a result, companies have began to adopt cross-platform solutions over the native solutions to create apps for both iOS and Android faster employing a single language. What’s Flutter and React Native? React Native may be a project started by Facebook internally that they open-sourced in 2015. On the opposite side is Flutter, a project started by Google which they need been heavily promoting since I/O 2017. Both of those technologies help app developers build cross-platform apps faster by employing a single programing language . React Native is already a mature tool and features a huge community, but Flutter also started seeing huge adoption rates since 2017. during this post, we'll compare each of them using ten criteria: Programming language Technical architecture Installation Setup and project configuration UI components and development API Developer productivity Community support Testing support Build & release automation support DevOps and CI/CD support Now that we've defined all our criteria, let’s start exploring each of them intimately . Programming Language The key advantage of employing a cross-platform mobile app development technology is that the ability to use one programing language to develop apps for both iOS and Android. React Native — JavaScript React Native uses JavaScript to create cross-platform apps. JavaScript may be a very fashionable language within the web community at the instant . it's commonly used with React and other popular JavaScript frameworks. because of React Native, web developers can build mobile apps with a touch little bit of training. With this in mind, companies adopted React Native as a no brainer . JavaScript may be a dynamically typed language and anything are often through with JavaScript, which is sweet and bad at an equivalent time. Flutter — Dart Flutter uses Dart programing language which was introduced by Google in 2011 and is never employed by developers. Dart syntax is straightforward to know for JavaScript or Java developers because it supports most of the object-oriented concepts. It’s easy to urge started with Dart as there's great and easy-to-follow documentation available on the official Dart site here. Technical Architecture When choosing a cross-platform mobile app development framework, it’s essential to think about its technical architecture. By knowing the internals of the framework, we will make an informed decision and choose the one that's better for our project. React Native — Flux React Native architecture heavily relies on JS runtime environment architecture, also referred to as JavaScript bridge. The JavaScript code is compiled into native code at runtime. React Native uses the Flux architecture from Facebook. there's an in depth article on the core architecture of React Native here. In short, React Native uses the JavaScript bridge to speak with the native modules. Flutter — Skia Flutter uses the Dart framework which has most of the components inbuilt so it’s bigger in size and sometimes doesn't require the bridge to speak with the native modules. Dart has numerous frameworks, like Material Design and Cupertino, packed inside which give all the specified technologies needed to develop mobile apps. The Dart framework uses Skia C++ engine which has all the protocols, compositions and channels. The architecture of the Flutter engine is explained intimately in Github Wiki here. In short, Flutter has everything needed for app development within the Flutter engine itself. Installation The installation method should be straightforward without having too many complicated steps in order that it might be easily learned by developers that are just starting with it. React Native — NPM The React Native framework are often installed using the Node Package Manager (NPM). For developers that have a JavaScript background, installation of React Native is straightforward , whereas other developers would wish to find out the node package manager. The node package manager can install the packages locally or globally. The developers will got to understand where precisely the binary is found . Whilst installing React Native on macOS, we'd like to possess the HomeBrew package manager also . Flutter — Binary Download from Source Flutter are often installed by downloading the binary for a selected platform from Github. within the case of macOS, we've to download the flutter.zip file and add it as a PATH variable. Flutter should improve the installation method by supporting package managers like Homebrew, MacPorts, YUM, APT, etc in order that users wouldn’t got to perform these extra steps during installation. Setup and Project Configuration The process of fixing the developer machine to use the new framework takes time. It requires many configuration of software installations. The technology should have proper documentation to urge users up and running. React Native The getting started guide of the React Native project assumes that the developer already has all the specified setup for developing for iOS and Android. there's little info on the Xcode instruction tools but it won’t be enough to urge going. The documentation directly jumps to the step of making a replacement project. Flutter The getting started guide for Flutter has detailed information on IDE setup and platform setup for both iOS and Android. you'll read all the specified setup details on Flutter install for macOS here. On top of this, Flutter features a CLI tool called flutter doctor which may guide developers through the setup. It inspects which tools are installed on the local machine and which tools got to be configured. Once the flutter doctor command is happy, we will keep it up with creating a replacement Flutter app. there's a separate page on the way to configure the editors to urge going with Flutter. Developer Productivity Developer productivity is that the key to putting together apps faster. during this regard, it’s vital to be ready to specialise in app development with none quite wait or distraction. React Native If the developer is skilled in JavaScript, then it’s fairly easy to use those skills for cross-platform app development. React Native features a hot reload feature which saves tons of developer time while testing the changes within the UI. In terms of IDE support, developers are liberal to use any text editor or IDE of their choice. Flutter Flutter also features a hot reload feature and it’s very easy to urge started with the demo app. However, because the complexity of apps grows, developers would wish to find out and adopt the new Flutter concepts. additionally , Dart isn't a standard programing language and there's a scarcity of support for it in many IDEs and text editors. React Native React Native launched in 2015 and has gained in popularity ever since. there's a community of React Native developers on GitHub and much of meetups and conferences round the world. one among the foremost recent conferences on React Native was React Native EU held in Poland, but there are meetups happening in almost every major city within the world. Flutter Flutter has been around for a short time but it gained tons of attention when Google promoted it within the Google I/O conference in 2017. The Flutter community is growing rapidly lately , meetups and conferences are happening online. the most important event coming are going to be Flutter sleep in December. In short, the Flutter community is growing rapidly; yet, there are still not enough resources for developers to unravel common issues. Testing Support Writing tests may be a good way to urge quick feedback on the code. there's always a testing framework related to every mature technology to permit developers to make unit, integration and UI tests for the apps. React Native React Native may be a JavaScript framework and there are a couple of unit level testing frameworks available in JavaScript. The tools like Jest are often used for snapshot testing. However, when it involves integration or UI level testing, there's no official support from React Native. There are third-party tools like Appium and Detox which will be used for testing React Native apps but they're not officially supported. Flutter Flutter provides an upscale set of testing features to check apps at unit, widget and integration level. Flutter has great documentation on testing Flutter apps here, you'll also read the Nevercode blog on testing Flutter apps for detailed information on how Flutter apps are often tested. Flutter features a cool widget testing feature where we will create widget tests to check the UI and run them at the speed of unit tests. Build & Release Automation Support Releasing mobile apps to the App Store or Play Store may be a painful process. It involves the complex task of code signing all another application setup. When it involves cross-platform mobile app development, it gets even trickier. React Native The React Native official documentation doesn’t have any automated steps to deploy the iOS apps to App Store. However, it provides a manual process for deploying the app from Xcode. there's a piece of writing on the way to deploy React Native apps to App Store here but the whole process looks manual. However, we will use third-party tools like fastlane to deploy iOS and Android apps written with React Native. the method of using fastlane to ship React Native apps is described during this article. this suggests that React Native has got to believe third-party libraries for build and release automation. Flutter Flutter features a strong instruction interface. we will create a binary of the app by using the instruction tools and following the instructions in Flutter documentation for building and releasing Android and iOS apps. On top of this, Flutter has officially documented the deployment process with fastlane here. DevOps and CI/CD Support Continuous Integration and Continuous Delivery practices are essential for any app so as to urge continuous feedback and avoid releasing buggy code. React Native React Native doesn’t have any official documentation on fixing CI/CD. However, there are some articles which describe CI/CD for React Native apps. there's a piece of writing which explains the method of fixing CI/CD for React Native apps with Nevercode. Flutter Flutter features a section on Continuous Integration and Testing which incorporates links to external sources. However, Flutter’s rich instruction interface allows us to line up CI/CD easily. Nevercode has inbuilt support for CI/CD for Flutter apps. The detailed blog post explaining the CI/CD process of Nevercode are often found here.
