How to Develop an Android App

To learn how to develop an android App you have to understand android first. After the invention of computers, it was just used among the mathematicians and scientists due to its complex usage and also it was a very expensive machine to buy at that time. But Integrated circuits and fast speed processors change the era of computers. IBM and its competitors started to build high speed, lesser size, and cheap computers. And in the mid-90s, Microsoft and Apple Inc. built the future of Advance User Interfaces. Due to this type of User-friendly Operating System, the number of users increases rapidly. Independent software companies and people begin to ask how to develop an app.

What is Android OS?

              Android is an operating system based on the Linux kernel, its motivation is to interface the client and the devices. For instance, when a client needs to send a book, Android furnishes the client with a button to tap. At the point when the client taps the button, Android guides the telephone to send the content. Consistently, Google makes significant updates to the Android working frameworks. Despite the fact that Google has a significant influence on the improvement of Android, Google gives the Android working framework to makers for nothing. Now it was the era to ask how to develop an android app. HTC, Samsung, LG, Huawei, Lenovo, and Sony are only a couple of the makers that run Android on the devices they produce. Android is currently running on one billion devices.

A typical inquiry that numerous individuals have is the reason Android appears to appear to be unique on various devices. The response to this is that there are various renditions of Android. Since Android is an open-source programming, producers can make changes to the product for better or in negative ways.

Now you got the idea about the platform now you’re ready to learn leading android application development software “Android Studio”.

Android Studio

Before you start Learning:

              Before start learning Android Studio, remember that there are different alternatives accessible for your Android application advancement. For instance, Unity is an incredible asset for cross-stage game advancement that additionally bolsters Android. In like manner, Visual Studio with Xamarin is an incredible mix for making cross-stage applications in C#.

There’re some skills that you should at least familiar to start development for Android Application and if you want to be an expert then you have to earn a lot of experience in them also:

  1. Java, Kotlin, or Both: Java and Kotlin are leading programming languages that used among the developers. This would be the most essential skill you should have before starting.
  2. Android SDK concepts: It’s an interpreter work on machines for connecting applications and OS and computers. In android, it’s Android SDK.
  3. Experience with RDBMS: Relational Database Management Systems or SQL is the language apps used to store data in database servers.
  4. Knowledge of Git: When you working on some projects with a team. Git is the skill to control the version of apps. It’s a plus point to have it by your side.
  5. XML Basics: Extensible Markup language is used in front-end and to design/Mange objects for human and machine readable at same time.
  6. Backend Programming Skills: While working on app, back-end would be the solution for your problem and how you manage it and telling the OS to do.
  7. Front-end Frameworks: User Interface is also important thing while developing application for all type of users. It makes your app look good.

Android Studio is the best platform for you people to start with android development. Especially as it gives all these extra apparatuses and assets in a solitary spot. Luckily, set up is exceptionally basic and you just need to track with the directions on the screen.

So can get help form below mentioned links:

Step-1:Start a new project

              When you finally get your Android Studio on your machine, the subsequent stage is to begin another task. This is a clear cycle;however, you’ll have to settle on a couple of choices that will effect on your Android application improvement going ahead.

In by far most of applications, you’ll have to make another Java/Kotlin record and a comparing XML document, each time you need another action. What’s more, for those that were pondering: indeed, that implies you need to adapt either Kotlin or Java and XML. This is a digit of a migraine, yet it really streamlines the cycle over the long haul.

Go to File > New > New Project. You will currently be approached to choose a “Task Template.” This shows the code and UI components that will be remembered for your new appwhen it loads.

“Activity” alludes to a “screen” in your application. In this way, an undertaking with “No Activity” will be totally vacant, aside from the fundamental document structure. A “Fundamental Activity” then again will make a beginning screen for your application and will include a catch in the base and a cheeseburger menu at the top. These are normal components in numerous Android applications, so this can spare you some time.

Pick a name and “Package name” for your new application. The name is the thing that your crowd will see when the application is introduced on their devices. The bundle name is an inward reference utilized by Android to separate it from different applications. This ought to be made utilizing your high-level space (for example .com), area name, and application name.

For Example: com.webherbinger.sampleapp.

Step-2: Introducing layout files

              The part of this code is to reveal to Android where the related design record is. A format record is somewhat unique in relation to a Kotlin/Java document. This shows the way that a display looks, and lets you include things like catches, text, and program windows. You’ll discover these files here: MyApplication > application > src > res >layout.

It will be called activity_main.xml. Note that records put away in the asset’s organizer can’t utilize capitals; they have to utilize the underscore image to recognize various words. Double tap on this record and it will open in the primary window where you alter your code. Notice that you can switch between the open documents utilizing tabs along the top.


In the plan see, you can really move various devices onto the screen. The code see shows you a heap of XML content. At the point when you include new devices through the Design see, this content will refresh. Similarly, you can change properties of the devices (called “sees”) in here and see them reflected progressively by means of the Code see.

In by far most of applications, you’ll have to make another Java/Kotlin record and a comparing XML document, each time you need another action. What’s more, for those that were pondering: indeed, that implies you need to adapt either Kotlin or Java and XML. This is a digit of a migraine, yet it really streamlines the cycle over the long haul.

Step-3: Test your App

              The primary thing that you should do while acclimating yourself with any new programming language, is to make an application that says “Hi World.” Thankfully, this is exceptionally simple for this situation seeing as that is the thing that the code that is nowhere does! On the off chance that you take a gander at the XML, it incorporates a little name that just says: Hello World!

On the off chance that you take a gander at the controls along the top, you’ll see there’s a little green play bolt. On the left of this is a drop-down menu, with a telephone name in it. At the point when you introduced Android Studio, this ought to likewise have introduced an Android framework picture alongside the Virtual Device Manager. As such, you should as of now have an Android emulator set up and all set! By tapping on this green bolt, you’ll have the option to dispatch that and test your application! Notice that this will likewise let you utilize the imitated telephone like it were a genuine device.

You can change the settings for your virtual devices –, for example, screen size, Android variant, space and so on – by going to Tools > AVD Manager. You can likewise download new framework pictures here. Ensure that your virtual devices meet or surpasses the base SDK you set toward the beginning.

On the other hand, you can take a stab at connecting a physical device to your PC and utilizing this to test your new application. You’ll have to turn on Developer Options however and empower USB Debugging.

    Hi there, first off I’d like to say that I have no idea about how to develop an app and I have no idea about androids.

    I have always wanted to learn how to develop an app. Being a designer in the display field, I find something like this very intriguing

    While I feel that I am pretty good at computers a lot of these terms that you’re mentioning are foreign to me. it’s kind of like HTML code which I would have no idea how to write.

    But it is something I would like to learn how to do. Learning how to develop an app would be very exciting for me especially for something like the android.

    My question to you is, would this be very difficult in learning how to do?

  • Nuttanee

    I have always wanted to develop my own app or games on the phone that will pick right off because all of my friends from the college can do it but they just got busy with life. Anyways, thanks for such a simple approach explanation about andrioid apps. I thought that it was gonna be way much harder. Thanks for the step bu steps, I am going to check it out.
