Use Android Support Library Media Compat in the Java Library to achieve multimedia support

Use Android Support Library Media Compat in the Java Library to achieve multimedia support Introduction: With the rapid development of mobile applications, multimedia support has become increasingly important in development.Android provides rich multimedia functions, but different versions of Android platforms may have different APIs.To solve this problem, Google provides a support library, Android Support Library, which contains many support components that have nothing to do with Android versions.Among them, Media Components provide support for multimedia functions and allow developers to use new multimedia APIs on the lower version of the Android platform. The steps of multimedia support using Media Compat are as follows: 1. Import SUPPORT LIBRARY and Media Compat components: In the project's Build.gradle file, make sure you have added dependence on SUPPORT LIBRARY.Add to the DEENDENCIES part: implementation 'com.android.support:support-media-compat:<version>' Among them, <Version> is the SUPPORT LIBRARY version you want to use. 2. Create a multimedia player: Media Compat provides the MediaPlayercompat class that can be used to create a multimedia player.Through the MediaPat.create () method, the MediaPlayer objects compatible with different platforms can be generated. The following is a sample code fragment: MediaPlayerCompat mediaPlayer = MediaPlayerCompat.create(context); In the above code, we use the Context object to create a MediaPlayercompat instance.You can pass different parameters as needed to create this instance. 3. Set multimedia resources: Through the SetDataSource () method, we can set the path or URL of multimedia resources to be played. mediaPlayer.setDataSource(context, uri); In the above code, we use Context objects and URI objects to set up multimedia resources. 4. Set the backback of the playback: Through the SetonCompleTionListener () method, we can set the callback method of player when playing. mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mediaPlayer) { // Operation executed during the playback } }); In the above code, we created an anonymous OncompleTionListener and defined the operation to be performed when the playback was completed. 5. Start playback: Using the Start () method, we can start the playback of multimedia resources. mediaPlayer.start(); In the above code, we use the Start () method to start the player. In addition to the above steps, there are many other operations that can be achieved through Media Compat, providing a consistent experience in different multimedia operations.You can find more details about how to use Media Compat in the Android developer documentation. In summary, by using Android Support Library Media Compat, we can achieve multimedia support on different versions of the Android platform, providing consistent multimedia functions and user experience. I hope this article can help you understand how to use Android Support Library Media Compat in the Java library to achieve multimedia support.
