An Activity typically has a layout associated with it that defines how UI elements appear on a screen.Īndroid Studio pre-populates your project with minimal code for an Activity and layout based on a template.

It is a crucial component of any Android app. Choosing an Activity templateĪn Activity is a single, focused thing that the user can do. That means your app should always be compatible with future versions of Android, if you use the documented Android APIs. Each successive version of Android provides compatibility for apps that were built using the APIs from previous versions.

The Minimum SDK declares the minimum Android version for your app. For instance, Android 1.0 is API level 1 and Android 4.0.3 is API level 15. To indicate which set of APIs are available, each version specifies an API level.

Each successive version often adds new APIs not available in the previous version. The choice shown in the figure for the Minimum SDK- API 15: Android 4.0.3 (IceCreamSandwich)-makes your app compatible with 97% of Android-powered devices active on the Google Play Store.ĭifferent devices run different versions of the Android system, such as Android 4.0.3 or Android 4.4. When choosing Target Android Devices, Phone and Tablet are selected by default, as shown in the figure below. Choosing target devices and the minimum SDK Be aware that changing the package name later is extra work. If you don't plan to publish the app, you can accept the default example domain. Because domains are unique, prepending the app's name with your name, or your company's domain name, should provide an adequately unique package name. When choosing a unique Company domain, keep in mind that apps published to Google Play must have a unique package name. Click Start a new Android Studio project in the Welcome window, and name the project the same name that you want to use for the app. Starting an Android Studio projectĪfter you have successfully installed the Android Studio IDE, double-click the Android Studio application icon to start it. Android Studio includes code templates with sample code for common app features, extensive testing tools and frameworks, and a flexible build system.

Publish the app by assembling the final APK (package file) and distributing it through channels such as Google Play.Īndroid Studio provides a unified development environment for creating apps for all Android-powered devices.

Use the default build configuration or create custom builds for different versions of your app.©

Build and run the app on real and virtual devices.

Create source code for all of the app's components.

Write code using the Java programming language.

You can place UI elements on the screen using the layout editor, or you can write code directly in the Extensible Markup Language (XML).

Define a layout for each screen that has UI elements.

Create the project in Android Studio and choose an appropriate template.

When you are ready to start coding, you use Android Studio to go through the following steps: To show what a UI would look like and how it would work, use drawings, mockups, and prototypes. You may want to sketch user interfaces (UIs) for the various app functions.

This chapter describes how to develop applications using Android Studio, which is an integrated development environment (IDE) for Android.Īn Android app project begins with an idea and a definition of the requirements necessary to realize that idea.

Running the app on an emulator or a device.
