Introduction:

Today I am starting to make a series of articles on Android   application development, so first of all, so we are clear, let's cover some basics: the history of Android Studio and basic structure of Android Studio.

What is IntelliJ IDEA?

Android Studio

Eclipse Android Developers Tool

  • Eclipse ADT is no longer under development.
  • Google removed links to download ADT bundle in December 2014.
  • Android Developers should now be using android studio.

Especially For Beginners

  • When you install android studio after completion on android studio you are facing some errors then simple you uninstall the studio and reinstall it.it is only the wastage of time nothing else.
  • So if we install with open eye and follow the overall steps it is too beneficial for us and then make a standard.
  • First you install JRE and JDK which is mandatory for android studio JDK and JRE .
  • Move to the SDK manager and download standalone version of SDK and install it Android SDK .
  • You can install the Android by clicking the link and download the latest version.
  • Android Studio for Windows

Step 1:

In first step we check whether JRE and JDK is present in our computer or not so we move to open command prompt and type some commands to check. We follow the three commands to check that Java components are installed in computer or not. In my computer I already have JDK or JRE but I can’t see the environments variables.

Step 2:

After installation move to the Control Panel and in search bar, search the environments variables then click on edit dialog which appears.

Step 3:

Now if you don’t find the JAVA_HOME directory then click on a new button and make the directory and set the name JAVA_HOME and give the JDK path and then press OK button. After doing this go to the command prompt and give the command and you see that now it gives an actual path.

Now install the Android studio and hopefully the installation has completed. Now we move to some common discussion about Android studio structure and pattern. Now open Android studio and make a new project, if you aren'y familiar with how to create the new project follow this article.
