Developing for Android x 27 Updating the ADT Plug-In In most cases, you can update your ADT plug-in simply as follows: 1. Navigate to Help Í Check for Updates. 2. If there are any ADT updates available, they will be presented. Simply select them and choose Install. Sometimes a plug-in upgrade may be so significant that the dynamic update mechanism can’t be used. In those cases you may have to remove the previous plug-in completely before installing the newer version, as described in the previous section. Using the Support Package The support library package (previously known as the compatibility library) is a set of static libraries that you can include as part of your projects to gain either convenience APIs that aren’t packaged as part of the framework (such as the View Pager), or useful APIs that are not available on all platform releases (such as Fragments). The support package enables you to use framework API features that were introduced in recent Android platform releases on any device running Android 1.6 (API level 4) and above. This helps you provide a consistent user experience and greatly simplifies your development process by reducing the burden of supporting multiple platform versions. It’s good practice to use the support library rather than the framework API libraries when you want to support devices running earlier platform releases and where the support library offers all the functionality you require. In the interest of simplicity, the examples in this book target Android API level 15 and use the framework APIs in preference to the support library, highlighting specific areas where the support library would not be a suitable alternative. To incorporate a support library into your project, perform the following steps: 1. Add a new /libs folder in the root of your project hierarchy. 2. Copy the support library JAR file from the /extras/android/support/ folder in your Android SDK installation location. You’ll note that the support folder includes multiple subfolders, each of which represents the minimum platform version supported by that library. Simply use the corresponding JAR file stored in the subfolder labeled as less than or equal to the minimum platform version you plan to support. For example, if you want to support all platform versions from Android 1.6 (API level 4) and above, you would copy v4/android-support-v4.jar. 3. After copying the file into your project’s /libs folder, add it to your project build path by right-clicking in the Package Explorer and selecting Build Path Í Add to Build Path.
