<\/a><\/p>\nSo the first step you need to do is to code your project and develop your application. After building your application, you need to test it, you can first go with UI Testing, and then you can test your app with some real-time users.<\/p>\n
Now, you need to sign your application with your company name and other credentials. The final step is to deploy your app on some marketplace.<\/p>\n
How to develop your Android App?<\/h3>\n
To develop your Android App needs, you need to follow the below steps:<\/p>\n You need to clear the errors from log cat and need to configure them in your Manifest File. You need to remove the android:debuggable<\/strong> attribute from the Manifest file and then add android:versionCode<\/strong> and android:versionName<\/strong> in your Manifest file.<\/p>\n You need to build your Gradle files and sign them up with your company name and credentials.<\/p>\n You can test whether or not the release version is working correctly or not.<\/p>\n It\u2019s a good practice to check whether all your graphical stuff like images and videos are correctly working inside your application.<\/p>\n When you are done with the steps, you need to set up your server for the application. This ensures security for your application.<\/p>\n As you know, we can make mistakes while developing an app. Sometimes we overlook those mistakes as a developer, but the users notice them. You would never allow such a scenario to happen wherein your app is released and you are getting tons of bug reports from the user.<\/p>\n A better practice is to test your application before publishing it. For this, you need to send your application to a group of people and take their reviews.<\/p>\n So, we need to generate a debug APK file and send it to the group for testing.<\/p>\n Now let\u2019s see the steps you need to follow to develop a debug APK.<\/p>\n Step 1:<\/strong> Start Android Studio and open the project that you need to publish.<\/p>\n Step 2:<\/strong> Now go to Tools —-> Select Build Variant.<\/p>\n Now the build variant window will appear, which is as follows. Here select debug.<\/p>\n Step 3:<\/strong> Now again, go to Tools and select Build Bundle(s)\/APK(s). Now proceed with build APK(s).<\/p>\n Step 4:<\/strong> Now, after your Gradle build completes, you get an option to locate your APK file. Now, this is the APK file which is the debug one.<\/p>\n So that\u2019s it. Your debug APK is ready with you; now, use it to test your application.<\/p>\n Now, above, you saw generating the debug APK file. Directly a question may arise.<\/p>\n Why do we need the release APK? Why can\u2019t we use the debug APK for publishing? The answer to this is because the debug APK is not signed and is not secured. Debug APK\u2019s never specify who the publisher is or who developed it.<\/p>\n Suppose you installed an APK from an unknown publisher, and then your phone got bricked now since the app had an undisclosed publisher, so you can\u2019t reach the developers with the issue.<\/p>\n Hence, it becomes essential for us to use release APK while publishing the app.<\/p>\n Let\u2019s see the steps you need to follow to develop the release APK.<\/p>\n Step 1:<\/strong> Open your project in Android Studio.<\/p>\n Step 2:<\/strong> Now go to Tools —-> Generate Signed Bundle\/APK.<\/p>\n Now a window will appear, where you need to select APK and proceed.<\/p>\n Step 3:<\/strong> Now, you need to select your key path if you otherwise click on create new.<\/p>\n Now you will get a window where you need to provide all the details and keep a password to sign in to your app.<\/p>\n Now, after this, just click on Ok.<\/p>\n Step 4:<\/strong> Now, after completing the above steps, you need to click on Next.<\/p>\n Now select release and select V2 to sign your application thoroughly. Now just click on finish.<\/p>\n So. that\u2019s it. Your release APK is ready with you, and you can proceed to publish it. You can locate your file in the app—->release folder of your project files.<\/p>\n Sometimes there are scenarios where you don\u2019t want to have Android Studio in your system, but you have a project build that you need to sign. So in such cases, you can use the command prompt to sign your application.<\/p>\n Step 1:<\/strong> You need to generate your private key for your application.<\/p>\n Step 2:<\/strong> Now, you need to build your project in release mode. After that, you need to sign in your application. For this, you can use jarsigner.<\/p>\n Step 3:<\/strong> Now, check whether your app is successfully signed or not.<\/p>\n Step 4:<\/strong> You need to align your application. For this, you need to use zipalign.<\/p>\n Android provides several ways to distribute your applications. We can broadly classify the places into two categories:<\/p>\n 1. App stores So now let’s each of them in detail and understand how you can publish your application in these places.<\/p>\n There are several app stores available that allow you to publish your android apps hustle-free. They also provide features to market your app and earn more users.<\/p>\n Some of such app stores are as follows:<\/p>\n 1. Google Play Store You can even use websites and blogs to share your application. Nowadays, all the giant companies have their app link mentioned on their landing page. For this, you can create your website or use exciting forums or blogs to post your application and gain users.<\/p>\n Google Play store is one of the biggest stores to distribute and market your android apps. Most of the android devices have google play store installed on their device. Now let\u2019s see how you can upload your apps on the google play store.<\/p>\n For understanding this, you need to follow the below steps carefully:<\/p>\n 1:<\/strong> Browse the Google Play Console Website from the link below. Now click on Go to my console and then login with your Gmail account. If you don\u2019t have one, then do create it. Without a Gmail account, you can\u2019t access the play console.<\/p>\n 2:<\/strong> After you successfully opened your console, it would ask you to create a developer account. You just need to fill in your details and then proceed.<\/p>\n<\/a><\/p>\n1. Configure<\/h4>\n
