However, as their default appearance is a bit ugly, you will be better off using some more advanced component framework. These components are quite flexible and there is nothing wrong on using them. You should now see "Hello World!" displayed in the app running on the emulator.īy default, the Android framework provides a bunch of UI components that you can use to build your app. Back in the Select Deployment Target dialog, select the device you just created and click OK.Ĭlicking on the OK button will make Android Studio start the emulator (it can take a couple of minutes as it is the first time you are using it) and open the app on it.On the Android Virtual Device (AVD) screen, leave all the settings alone and click Finish.If that is the case, click the link and complete the download.

For that, you have two options: you can run the app on a real device (like your Android mobile phone), or you can use an emulator.

Lastly, if you have prior knowledge around Java development, you will benefit a lot from it. If you don't have it yet, you can download Android Studio from this resource. Second, you will need Android Studio, the official Integrated Development Environment (IDE) for Android. If you don't have it, follow the instructions here to download a JDK. First, you will need Java Development Kit 7 (JDK 7) or higher on your computer. To follow along with this tutorial, there are two things you will need and a third one that you can benefit from.
