Use Android Virtual Device Manager

The Android Virtual Device Manager allows you to create an Android Virtual Device (AVDs), and then you can run the simulator on your computer. Simulation and simulation have a very important but subtle difference. Simulation means that the virtual device has only one shape, simulating how the actual physical device operates, but not for a specific operating system. However, for the simulator, your computer sets aside a piece of memory to copy the environment based on the simulator that is simulating the device. Android Studio uses the simulator, which means that the Android Virtual Device Manager starts a sandbox of the Linux kernel and the entire Android stack to simulate the environment based on the Android physical device. Although the simulator provides a more reliable environment than the simulator to test your application, it takes several minutes to start an AVD, depending on the speed of your computer. The good news is that your simulator is still active in the memory and it still responds. However, if you have an Android phone or tablet, we recommend that you use a physical device to test your application instead of AVD. That is to say, we first use the Android Virtual Device Manager to create an AVD.

Click the Android Virtual Device Manager icon.

On the first page of the Android Virtual Device Manager wizard, Click create virtual device. Select Nexus 5X on the next page,

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

Click Next. On the next page, click Finish to verify your AVD settings. Congratulations, you have created a new AVD.

Green run button on the single-host Toolbar

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