Specify the location of local machine path for Android studio and Android SDK and then click on next button.
Android Studio
Now specify the ram space for Android emulator by default it would take 512MB of local machine RAM

Android Studio
The next level contain selecting the activity to mobile, it specifies the default layout for Applications
Android Studio
At the final stage it going to be open development tool to write the application code.
Android Studio
Create Android Virtual Device
To test your Android applications, you will need a virtual Android device. So before we start writing our code, let us create an Android virtual device. Launch Android AVD Manager Clicking AVD Manager icon or click on View>AVD Manager as shown below
Android Studio
After Click on a virtual device icon, it going to be shown by default virtual devices which are present on your SDK, or else need to create a virtual device by clicking Create new Virtual device button
Android Studio
If your AVD is created successfully it means your environment is ready for Android application development. If you like, you can close this window using top-right cross button. Better you re-start your machine and once you are done with this last step, you are ready to proceed for your first Android example but before that we will see few more important concepts related to Android Application Development.
Hello Word Example
Before Writing a Hello word code, you must know about XML tags .To write hello word code, you should redirect to App>res>layout>Activity_main.xml
Android Studio
To show hello word, we need to call text view with layout ( about text view and layout, you must take references about Relative Layout and Text View ).

<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android”
xmlns:tools=”http://schemas.android.com/tools”
android:layout_width=”match_parent”
android:layout_height=”match_parent”
tools:context=”.MainActivity”>
<TextView android:text=”@string/hello_world”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content” />
</RelativeLayout>

Now run the program by clicking Run>Run App or else need to call shift+f10 key. Finally, result should be placed at Virtual devices as shown below or you can run it on your own android device.
