6. New first project: HelloWorld

The Android operating system can run on a variety of platforms, including game consoles, televisions, watches, eyewear, smartphones and tablets. By default, the phone and tablet check box is selected and API-8 is selected as the lowest SDK. Agree to these settings and click Next,

Subsequent new project wizards will prompt you to choose a layout. Select the blank activity and click the Next button. Agree to the default name, and they should be as follows:

Using Android virtual Device Manager

Android Virtual Device Manager allows you to create an Android virtual device (AVDs) and then you can run the emulator on your PC. Simulation and simulation have a very important but subtle difference. Simulation means that the virtual device has only one form factor, simulating how the actual physical device works, but not for a particular operating system. For emulators, however, your computer leaves a piece of memory to replicate the environment on which the emulator is simulating the device. Android Studio uses the emulator, which means that Android virtual Device Manager launches a large sandbox for the Linux kernel and an entire Android stack in order to emulate an Android-based physical device environment. Although the emulator provides a more reliable environment than the emulator to test your application, it can take several minutes to start an AVD, depending on the speed of your computer. The good news is that your emulator is still active in memory and it's still responsive. However, if you have an Android phone or tablet, we recommend using a physical device to test your application instead of using the AVD. In other words, we first create an AVD using the Android virtual Device Manager.

Click the Android Virtual Device Manager icon.

In the first interface of the Android Virtual Device Manager wizard, click the Create a virtual device button. In the next interface select Nexus 5X,

Then click Next. The next interface allows you to select a system image.

Click Next. On the next screen, click the Finish button to verify your AVD settings. Congratulations, you've created a new AVD.

Green Run button on stand-alone toolbar

Make sure the Launch Emulator radio button is selected, and then select Nexus. Click OK and wait a few minutes for the AVD to start. Then you should be able to see the HelloWorld application running on your computer simulator.
