2.Android Development Tools



⬜Before we begin coding in Android , we need to setup our system for Android development.

⬜For many years, Eclipse IDE with the ADT plugin was the preferred platform for Android
development. Today it's Android Studio

⬜Android Studio is the official Integrated Development Environment (IDE) for Android app development, based on IntelliJ IDEA .

⬜It was announced on May 16, 2013 at the Google I/O Conference and finally in 2015 it totally replaced Eclipse as one and the only official Android IDE.

✷Some Screenshot of installing android Studio.




☐Launch the android-studio-bundle-xxx-windows.exe to start the installation process. The installer responded by presenting the Android Studio Setup dialog box shown below


☐Clicking Next will take you to the following dialog box, which gives you the option to decline installing the Android SDK (included with the installer) and an Android Virtual Device (AVD).


☐Keep the default settings. After clicking Next, you'll be taken to the license agreement dialog box. Accept the license to continue the installation.


 ☐The next dialog box invites you to change the installation locations for Android Studio and the Android SDK.



☐Change the location or accept the default locations and click Next.

☐The installer defaults to creating a shortcut for launching this program, or you can choose to decline.

☐It is recommended that you create the shortcut, then click the Install button to begin installation.


☐The resulting dialog box shows the progress of installing Android Studio and the Android SDK. Clicking the Show Details button will let you view detailed information about the installation progress.

☐The dialog box will inform you when installation has finished. When you click Next, you should see the following:


☐To complete your installation, leave the Start Android Studio box checked and click Finish.

☐Android Studio presents a splash screen when it starts running:


☐On your first run, you'll be asked to respond to several configuration-oriented dialog boxes.

☐The first dialog box focuses on importing settings from any previously installed version of Android Studio.

☐If you don't have a previously installed version, you can just keep the default setting and click OK.


☐Android Studio will respond with a slightly enhanced version of the splash screen, followed by the Android Studio Setup Wizard dialog box:

✱Running android studio.

⬜On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.

⬜Choose Start menu⇒Computer⇒System Properties⇒Advanced System Properties. Then choose Advanced tab⇒Environment Variables and add a new system variable, JAVA_HOME, that points to your JDK folder — for example, C:\ProgramFiles\Java\jdk1.8.0_75.

⬜When you click Next, the setup wizard invites you to select an installation type for your SDK components.

⬜For now it is recommended that you keep the default standard setting.



⬜Click Next and verify your settings, then click Finish to continue.


⬜The wizard will download and unzip various components. Click Show Details if you want to see more information about the archives being downloaded and their contents.


⬜Finally, click Finish to complete the wizard. You should see the Welcome to Android Studio dialog box:

Thanks . . .
