To set a one, use setDataSource() method. Initialized State: MediaPlayer reaches this state when you set a data source.However, you can catch the error using MediaPlayer’s onErrorListener.onError() callback. Error State: You reach this state if you try to play, pause or stop an uninstantiated MediaPlayer object.At this stage, you can’t play or pause the media. End State: Calling MediaPlayer‘s release() method frees resources and moves it to the end state.If you try to force it, the app might crash. You also reach this state after you call reset().Īt this stage, you can’t play, pause or stop the media. Idle State: MediaPlayer is in an idle state when you first instantiate it, or first create it using the new keyword.That’s a lot of information to take in, but before you can use the MediaPlayer API efficiently, you need to understand these states, so let’s take a look at each of them. When a media file plays, the MediaPlayer API goes through several states, which are summarized in the diagram below: It also streams music or video from a URL. ![]() MediaPlayer is a part of the Android multimedia framework that plays audio or video from the resource directory and gallery. You don’t want the user’s device to fall asleep and lock while they’re watching a video on your app, do you? Setting this flag ensures your screen stays on, while the app is in use. Notice this line inside onCreate() which adds a flag window.addFlags(_KEEP_SCREEN_ON). You’ll understand these implementations once you start working on the functionality.Īlso, to keep your app from falling asleep, you’ll need to keep your screen on. The class implements a few interface classes to manage MediaPlayer and seekBar callbacks. VideoActivity.kt: This might look a bit overwhelming, but if you skim through and read the comments, you’ll find it quite simple.An ImageButton to play and pause a video.Two TextViews and a SeekBar to show progress.A ProgressBar to shows the user it’s loading a video.activity_video.xml: This is the one and only layout file in the project.In this tutorial, you’ll play a video from a URL, so you’ll need the INTERNET permission. AndroidManifest.xml: At the top of the manifest file you’ll find.Navigate to these three files and check out their contents: ![]() Understanding the codeīefore the hands-on part of this tutorial, take some time to understand the codebase you’ll build on. You’ll implement the functionality throughout this tutorial. The app isn’t interactive yet because the starter project only consists of UI and some basic code. Extract and open the starter project in Android Studio.īuild and run.
