You can alter the minimum SDK here or optionally modify it in the Manifest file.Ĭlick "Finish" and Eclipse will build your project. However, we are going to include an Activity to provide information about using the widget, so we will let Eclipse create the Activity for now. When you develop a widget app, you do not need to create an Activity, so you can optionally uncheck the "Create Activity" section. In the Application Info window, enter your package name. Select a build target for your app and click "Next." We are targeting Android 4.0, which is API level 14. Start your project in Eclipse in the usual way, choosing "File," "New" and then "Project." Select "Android Project" from the list and then press "Next." In the "New Android Project" window, enter the name you want to use for your widget project and click "Next." If you have only created standard Android apps in the past, creating a widget project is a little different. This initial tutorial only involves a few steps, but understanding each of them is vital for learning the essentials of widget development. In this first part of the series, we will setup our widget project, add the necessary elements to the Manifest file, and create the XML resource file that will define the basic properties of the widget. Here's a snapshot of what the end result will look like with the default display (i.e. This tutorial series on Building a Customizable Android Analog Clock Widget is in four parts: We will also specify the layout and various other application resources in XML. For this reason, and to accommodate some issues with devices running Android 4.0 (Ice Cream Sandwich), we will also include an informative launcher Activity for the widget app. As you may have noticed, the Google Play listings for widgets often have poor ratings and comments from users who don't realize a widget is not launched in the same way as a normal app. We will also allow the user to configure the widget appearance by clicking on it, with an Activity class handling user interaction. We will define the properties of the widget in XML, with a Java class extending AppWidgetProvider to manage updates. Once the clock is added to the user's homescreen, it will continuously update to display the current time.
The clock will be based on the Android AnalogClock class and customized with your own graphics. In this series of tutorials, we will work through the process of developing a customizable analog clock widget. Developing widgets for the Android platform involves a slightly different set of tasks than standard app development.
