You can configure different layouts for the difference device properties to handle such situations. The dual view is not particularly practical on the G1. Step 7: Updating the Layouts (Optional)Īs you can see from the above screenshots, the text size and room for the WebView vary by device. Of course, it still works and looks the same on the Motorola Xoom.

Here's the sample app running on a Nexus S running Android 2.3.3 at 800x480: At this point, you can load the app on almost any device and run it.

Now update the manifest setting for minSdkVersion to 4 and targetSdkVersion to 10.

Change the call to the getFragmentManager() method to the getSupportFragmentManager() method.

Change the Activity to extend the FragmentActivity class.

For both TutListActivity and TutViewer Activity, follow these steps: Updating the two Activity classes is a bit more involved. Step 4: Switching to the Support Version of the Activity The final application will be compatible with 1.6 and we'll update or minSdkVersion in the manifest to show that. Why Android 2.3.3 instead of Android 1.6? Primarily this is to avoid changing out layout references to 'match_parent' with 'fill_parent'. Fixing the compile errors in TutListFragment and TutViewerFragment is trivial: simply open them and press ctrl-shift-o to switch around the import statements automatically to the appropriate APIs from the compatibility library instead of the Android 3.0 libraries. When you do this, you'll notice several compile errors. Instead, switch your project build target to API Level 10 (Android 2.3.3). We aren't using anything else from Android 3.0 (on purpose) so we no longer need to rely on the Android 3.0 SDK. The external library will provide the interface we need for the Fragment API use. Step 3: Updating the Project Build Target

You'll see how this is done if you download the code corresponding to this tutorial. In particular, you'll likely need to do this if you're using source control or otherwise sharing your application project.

Note: You may need to copy the JAR into your project directory and reference it via 'Add JARs' button instead. Then choose 'Install selected' and follow the on-screen instructions, including possibly restarting Eclipse.

To do this from within Eclipse, open the Android SDK and AVD Manager, click on Available packages, expand Android repository, and then choose Android Compatibility package, currently revision 1. Step 1: Downloading the Packageīefore you can use the Compatibility package, you must download it. You can download that code and build from there, though you will have some tasks you'll have to do unassisted, or you can download the code for this tutorial and follow along. This tutorial assumes you will start where our Fragment API tutorial left off. The final sample code that accompanies this tutorial is available for download as open-source from the Google code hosting.

As of this writing, that covers 97% of all Android devices actively accessing the Android Market. This package provides support for the Fragment API as well as other key new features to devices as far back as Android 1.6.

When you were reading the last tutorial on how to use fragments, you were probably thinking, 'Wow, this is great, but I can't use any of this because I need to target more than just the Motorola Xoom, the only Android 3.0 device currently on the market.' Luckily for all of us developers, Google has released a library called the Android Compatibility package. Android 3.0, or Honeycomb, came with some fundamental user interface changes, most notably in the form of the Fragment API.
