Android Studio is the official IDE (Integrated Development Environment) for Android application development and it is based on JetBrains’ IntelliJ IDEA software. Android Studio provides many excellent features that enhance productivity when building Android apps, such as:

  • A flexible Gradle-based build system
  • A fast and feature-rich emulator
  • A blended environment where one can develop for all Android devices
  • Apply Changes to push code and resource changes to the running app without restarting the app
  • GitHub and Code template integration to assist you to develop common app features and import sample code
  • Extensive testing tools and frameworks
  • C++ and NDK support
  • Built-in support for Google Cloud Platform, making it easy to integrate Google Cloud Messaging and App Engine and many more.

Generally, when a developer wants to create a new project in the android studio he/she needs to select a project template which is consisting of many activities as shown in the below image. (Considering that the developer developing the android app for phone and tablet). So in this article, we are going to discuss what do these activities mean in brief. Here is the list of activities:

  1. No Activity
  2. Basic Activity
  3. Bottom Navigation Activity
  4. Empty Activity
  5. Fullscreen Activity
  6. Google Admob Ads Activity
  7. Google Maps Activity
  8. Login Activity
  9. Master/Detail Flow
  10. Navigation Drawer Activity
  11. Settings Activity
  12. Scrolling Activity
  13. Tabbed Activity
  14. Fragment + ViewModel
  15. Native C++

Different Types of Activities in Android Studio

(1) No Activity

As the name suggests No Activity means creating a new empty project. When the developer selects this activity there will be neither an XML file nor a Java/Kotlin file. No files are automatically generated when you select No Activity. The project structure will look like the following:

(2) Basic Activity

Basic Activity creates a new basic activity with the navigation component. When the developer selects the basic activity, then you will be getting a menu button, and you will also get a floating action button. These files are automatically created when you select Basic Activity:

(4) Empty Activity

This is a popular activity and we frequently select this activity when we start developing an android project. It simply creates a new empty activity.

 These files are automatically created when you select Empty Activity and the following is the welcome page: 



(5) Fullscreen Activity

Fullscreen activity creates a new activity that toggles the visibility of the system UI (status and navigation bars) and action bar upon user interaction. Many apps are using Full-Screen Activity to have an attractive screen to show slides etc. These files are automatically created when you select Fullscreen Activity and the following is the welcome page:

(6) Google Admob Ads Activity

To earn money from the Android app or game, there are many ways such as in-App Purchases, Sponsorship, Advertisements, and many more. But there is another popular method to earn money from the Android app is by integrating an advertisement e.g known as Google AdMob. Google AdMob is designed with developers in mind, AdMob helps to earn more app revenue, deliver better user experience, and surface actionable insights all with automated tools that do the hard work for you. There are mainly four types of flexible, high-performing format available in Google AdMob

  • Native: Ads that you design to fit the app, seamlessly
  • Interstitial: Full-screen ads that capture attention and become part of the experience.
  • Banner: Traditional formats in a variety of placements.
  • Rewarded Video: An immersive, user-initiated video ad that rewards users for watching.

In Android Studio Google Admob Ads Activity creates an activity with AdMob Ad fragment. These files are automatically created when you select  Google Admob Ads Activity and the following is the welcome page:

(7) Google Maps Activity

Android permits to integrate google maps in our application. One can show any location on the map or can show various routes on the map etc. One can also customize the map according to the choices. So Google Maps Activity creates a new activity with a Google Map. These files are automatically created when you select Google Maps Activity and the following is the welcome page:

(8) Login Activity

As the name suggests Login Activity creates a new login activity, allowing users to enter an email address and password to log in or to register with the application. Login Activity is one of the most common activities that almost every application contains this activity. These files are automatically created when you select Login Activity and the following is the welcome page:

(9) Master/Detail Flow

Master/Detail Flow creates a new master/detail flow, enabling users to view a collection of objects as well as details for each object. This flow is presented using two columns on tablet-sized screens and one column on handsets and smaller screens. This template creates two activities, a master fragment, and a detailed fragment. These files are automatically created when you select Master/Detail Flow and the following is the welcome page: 

Master/Detail Flow

(10) Navigation Drawer Activity

Android Navigation Drawer is a sliding left menu that is used to display the important links in the application. The Navigation drawer makes it easy to navigate to and fro between those links. It’s not visible by default and it needs to open either by sliding from left or clicking its icon in the ActionBar. In broader terms, Navigation Drawer is an overlay panel, which is a replacement of an activity screen that was especially dedicated to showing all the options and links in the application. These files are automatically created when you select Navigation Drawer and the following is the welcome page:

(11) Settings Activity

Setting Activity creates a new activity that allows a user to configure application settings. These files are automatically created when you select Settings Activity and the following is the welcome page: 

(12) Scrolling Activity

Scrolling activity is an essential activity to have in the app as it provides the users with a perfect view when the layout is long. It creates a new vertical scrolling activity. These files are automatically created when you select Scrolling activity and the following is the welcome page: 

Scrolling Activity

(13) Tabbed Activity

In Android, TabLayout gives a horizontal layout to display tabs. If TabLayout is used then along with it, Fragment is also used, because fragments are lightweight and the app can have more functionality on a single screen if more fragments are added. Whenever the user clicks on the tab it will lead to the transaction of one Fragment to another. ViewPager is used to swipe between the tabs. WhatsApp, Facebook, etc. are a perfect example of TabLayout with ViewPager. This is how a TabLayout looks like.

Tabbed Activity creates a new blank activity with tabs. These files are automatically created when you select Tabbed Activity and the following is the welcome page: 

Tabbed Activity

(14) Fragment + ViewModel

As the name suggests Fragment + ViewModel creates a new activity and a fragment with the view model. 

  • Fragment: A Fragment is a piece of an activity which enable more modular activity design. A fragment encapsulates functionality so that it is easier to reuse within activities and layouts.
  • ViewModel: It exposes those data streams which are relevant to the View. Moreover, it servers as a link between the Model and the View. Model: This layer is responsible for the abstraction of the data sources. Model and ViewModel work together to get and save the data. View: The purpose of this layer is to inform the ViewModel about the user’s action. This layer observes the ViewModel and does not contain any kind of application logic.

These files are automatically created when you select Fragment + ViewModel and the following is the welcome page: 

Fragment + ViewModel

(15) Native C++

Native C++ creates a new project with an empty activity configured to use JNI. JNI is the Java Native Interface. JNI describes a way for the bytecode that Android compiles from executed code that is written in the Java or Kotlin programming languages to interact with native code that is written in C/C++. JNI is vendor-neutral, has support for loading code from dynamic shared libraries, and while cumbersome at times is efficient.
