Android Studio
If you have finished previous lessons,you already know some basic parts of Android Studio.
Cancel to load Project
When we start Android Studio, it will automatically detect lastly opening project and load it for you.You can simply cancel it if you want to create a new project or open another project.
Opening an existing Project
To open an existing android Project from your hard Disk look up Recent Project from welcome screen then click on project or Click Open an existing android Studio Project.
Or if you want to import an existing project, Click on File >> Import Project. Then navigate to the location where you have set Project location.(if you do not change default path: "C:\Users\{user name}\AndroidStudioProjects\HelloWorldapp")
Closing an opening project
To close an opening project Click File >> Close Project.
Updating Android Studio
Even though you just downloaded Android Studio, you might not actually have the latest version. Right away, you need to check to see if any updates are available and if necessary, follow any instructions to get the latest version. You can check whether any updates are available by clicking check for updates at the bottom of the welcome screen. If an update is available you will have a window like this appear:
When you see this screen. Always choose Update and Restart. In some cases, you may need to download the full installer – in that case you will see a Download button that will take you to instructions for installing.
Android Virtual Device (AVD)
We have already made an HelloWorld app and tested it so,we know about Emulator or Android Virtual Device(AVD) and how to create an Emulator like Nexus S which is Android 5.0 (Lollipop) and API Level 21,
You can create an Emulator on Android other version known as Android SDK.Each version of Android has it’s own SDK you can use to build apps that can run on.As part of the Setup Wizard you will already have the latest SDK available to you, however it’s useful to know how to install additional SDK’s if you need to work with older devices that do not run the latest version of Android.

SDK’s allow you to create AVD’s (Android Virtual Devices) to test your Apps on, customized to your personal configuration. Want to see how your Android App looks on a TV sized screen? If you have a screen big enough you can find out. More on AVD’s

Click on AVD Manager >> Create Virtual Device >> Select Phone type then Click Next.Wait, you will see a list of all android version with download option.
The Android SDK Manager
You can also Download SDK from SDK Manager.
Lets get to it. From the Android Studio welcome screen, click Configure.
The menu will slide across and present a new menu with various options. The option you want is the SDK Manager.It also contains other useful things such as API documentation, version specific code samples and even previews of software kits that interact with Android such as Android Wear and Google Glass.
You may download what you need.For now lets download the previous version of Android, that being Android 4.4.2 (API 19).
Click the tick box next to the folder icon for Android 4.4.2, this will select everything within that directory for download. You can always come back to the SDK Manager to delete anything you don’t use.
