The Activity will be named "ClockChoice" and we will add to the project in Part 4.
Providing a launch Activity prevents this issue.Īfter the closing Activity tag, but inside the Application element, add another Activity element for the screen we will include to let users select a custom clock style: However, in some cases a new widget does not appear in the Widget tab - normally this is solved when the device is restarted, but it can of course cause confusion and prevent the use of your app. In 4.0, users add widgets by opening the device menu, selecting the Widget tab, finding the widget listed there then pressing to hold it, dropping it onto the homescreen.

There is an issue with widgets running on Android 4.0 that sometimes prevents users from being able to add new widgets to their screens.

When this happens, we can use the main launcher Activity to display a little informative text explaining how to add the widget - preempting any negative comments or ratings from confused users. When users download a widget through Google Play, they often instinctively attempt to open it, forgetting or not knowing that widget apps are not launched in the normal way but are instead added to the homescreen.However, we are going to leave this section as it is. By targeting level 14, we can make use of the automatic margin space between widgets that appears on devices running Ice Cream Sandwich.Īt this point, you could edit the main Activity section of the Manifest if you did not want to use a launcher Activity. If you did not alter the minimum SDK when you created the project, but you wish to do so now, you can alter the "uses-sdk" element as in the following example:Īs well as specifying the minimum SDK here, we also indicate the target SDK.

Double-click to open it, then select the "AndroidManifest.xml" tab so that you can edit the XML code directly. Open your project Manifest file - it should be saved as "AndroidManifest.xml" in the project folder, visible within the Package Explorer. 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.
