How to start developing for Android?

Now the most active is the creation of application codes for the mobile operating system from Google. Therefore, it is worth thinking about how to start developing for Android - this is a very profitable occupation. But you need to learn and know the important points so that all applications turn out the way they should be. And so that there are no difficulties - it is also worth paying attention to this material, which will help in the future.

Install the AndroidStudio development environment


To start your activity, you need to get special software. In this case, the user is provided with a lot of AndroidStudio packages – there are several platforms for development on any computer. And it does not matter - macOS, Linux or Windows are used, because everywhere the program has the same functions.

The installation and configuration algorithm itself is not complicated and will take only a couple of minutes:

  1. The first thing to do is to go to the developer's website. There are a lot of packages where you need to choose only one. It will collect all the information for the installation process;
  2. Next, when you download a file for Linux, Windows, macOS, or Solaris, you need to open it. The installer is launched, during which it is required to follow the instructions in the installer;
  3. There may be several different scenarios. The first and easiest is Windows. There is no need for any additional effort to make and climb into the console. After all, everything can be done directly in the window, which opened after launching the executive .exe file. You just need to select the options for installation (but it is better to leave everything as it is) and click "Next". Eventually, the software will be installed and a new program can be opened;
  4. On macOS, the installation process is done a little differently. Since most installation files are disk images, anything can be located there (as in iso on Windows). However, the installation process is simple. The program, in most cases, is presented in the form of a ready-made application that can be immediately opened and viewed for operability. To install, you need to transfer it to the desktop or to another folder (preferably in "Applications"). Then it will appear in the Launchpad menu and you can quickly launch it;
  5. On Linux, you can get by with the usual scrolling through the steps in the graphical interface of the system. In the console, you can also do this, but some are more accustomed to using the first method. The file that was downloaded has a .deb format that you want to open and then the installation window will appear. You just need to follow the instructions of the installation wizard, after which the process itself will pass. All that's left is to open AndroidStudio and work on your projects.
  6. If you want to expand the functionality, you can also go to the Menu Tools – Android – SDKManager. There it is worth noting all the components that will be required in the process of work. There will be both old and new software elements;
  7. And the most important thing you need to do after installation is to configure the emulator to properly test your applications. To go to this menu, you need to go to Tools–Android–AVDManager. There are the usual gadgets (smartphones and tablets), as well as TV, smart watches on Android and cars with a special shell from Google. You need to select the model of the device, as well as download the software for it - after that everything will be ready.

In addition, in the future, you can download additional software that will simplify the work on a project or introduce new functions for a greater range of possibilities in a new application. It all depends on which extension the user chooses - each has its own development needs. So, in a sense, you can make your program as unique as possible - different from ordinary options in certain aspects.

General rules for Android applications


Before you write an application that will later be published on GooglePlay, you need to familiarize yourself with the rules. Nevertheless, the Android store is demanding of content, because if you continue to clog the search pages with your various creations with unacceptable content, the administration will simply prohibit the user from laying out applications.

There are a few main points to consider when publishing your program:

  • There should be no non-normative content. This includes: content that compels the sale / purchase of prohibited goods, the implementation of tragic situations (including terrorist acts, etc.), using discriminatory statements and more. Sometimes some situations are acceptable when the information is published for educational purposes;
  • You can not plagiarize other programs and pass them off as your own;
  • It is unacceptable to add the function of trading cryptocurrency, binary options and so on;
  • It is not allowed to force in the applications to commit illegal actions, as well as to publish offers to purchase prohibited substances.

This is not all that a developer should know. However, such basic points are the main ones, which is why when an idea arises for your software, you need to see if this or that rule is violated. If everything is in order, you can start working on the code and shell. However, an even better option would be to familiarize yourself with the full list of rules on the Google site - then definitely nothing will be deleted.

It is also recommended to follow the updates, because maybe the list of rules will be updated, which is why some points in the software will become violations, which is undesirable.

What are the official Android resources?


To facilitate the process of infusion into the field of programming on Android, it is worth paying attention to some resources. They contain, for the most part, exclusively informational in nature - there are often no proposals and ideas about programs.

Here are some resources for beginners:

  • Google Android Glossary;
  • XML Basics;
  • Official Android Training Guides;
  • Android Development for Beginners;
  • And others similar.

However, if such official resources do not indicate any problems that arise with AndroidStudio or something else, then you can turn to skillful users. To do this, there are special forums dedicated to programming and software - 4PDA and Habr. They can definitely give advice leading to the solution of a particular problem in order to continue their work and release a serviceable project.

My First Android Project: Code


To create your own code for a future full-fledged program, you need to start learning programming languages for Android now. Often, Java is used, but you can also use another one. However, the fact remains that one needs to know what to write and how to write. Therefore, it is recommended to look at the training resources and develop.

My first project under Android: Interface


But in addition to creating code, you need to think about how everything will look. To do this, there is a special emulator built into the program. Before you write, AndroidStudio will offer to select the interface parameters themselves, where everything that is required for the user will appear. What will be there in terms of content - a person himself will decide based on his idea.

AndroidStudio allows you to adapt the interface to any device. The main thing is to work on the very option of displaying the content, because the permissions are completely different. And therefore, if the screen is too large, where the image quality is 2K, then the text may not be displayed correctly. It's the same by analogy with small displays. In general, you need to pay considerable attention to this, as well as the code itself. Still, the convenience of use depends on it.

Following all these tips and instructions from this material, the user will get a basic idea of developing Android programs. It is also advisable to study information from other recommended sources. Then you will definitely have the necessary knowledge for subsequent actions in AndroidStudio.
