23.1 Creating the Example Project in Android Studio
Launch Android Studio and select the Start a new Android Studio project option from the quick start menu in the welcome screen and, within the resulting new project dialog, choose the Empty Activity template before clicking on the Next button.
Enter JavaLayout into the Name field and specify com.ebookfrenzy.javalayout as the package name. Before clicking on the Finish button, change the Minimum API level setting to API 26: Android 8.0 (Oreo) and the Language menu to Java.
Once the project has been created, the MainActivity.java file should automatically load into the editing panel. As we have come to expect, Android Studio has created a template activity and overridden the onCreate() method, providing an ideal location for Java code to be added to create a user interface.
