Streaming Video in Android Apps

Scroll to top
Read Time: 7 min

The Android platform provides libraries you can use to stream media files, such as remote videos, presenting them for playback in your apps. In this tutorial, we will stream a video file, displaying it using the VideoView component together with a MediaController object to let the user control playback. This is helpful if you're working on a video streaming Android app.

We will also briefly run through the process of presenting the video using the MediaPlayer class. If you've completed the series on creating a music player for Android, you could use what you learn in this tutorial to further enhance it. You should be able to complete this tutorial if you have developed at least a few Android apps already.

Wondering how to play online video in Android? Read on for the instructions on how to do it yourself. Follow this Android streaming app tutorial:

1. Create a New App

Step 1

You can use the code in this tutorial to enhance an existing app you are working on or you can create a new app now in Eclipse or stream video Android Studio. Create a new Android project, give it a name of your choice, configure the details, and give it an initial main Activity class and layout.

Step 2

Let's first configure the project's manifest for streaming media. Open the manifest file of your project and switch to XML editing in your IDE. For streaming media, you need internet access, so add the following permission inside the manifest element:

2. Add VideoView

Step 1

The Android platform provides the VideoView class in which you can play video files. Let's add one to the main layout file:

Alter the parent layout to suit your own app if necessary. We give the VideoView instance an id attribute so that we can refer to it later. You may need to adjust the other layout properties for your own design.

Step 2

Now let's retrieve a reference to the VideoView instance in code. Open your app's main Activity class and add the following additional imports:

Your Activity class should already contain the onCreate method in which the content view is set:

After the setContentView line, let's get a reference to the VideoView instance as follows, using the id we set in the XML layout:

3. Stream a Video File

Step 1

Now we can stream a video file to the app. Prepare the URI for the endpoint as follows:

You will of course need to use the remote address for the video file you want to stream. The example here is a public domain video file hosted on the Internet Archive. We parse the address string as a URI so that we can pass it to the VideoView object:

Now you can simply start playback:

The Android operating system supports a range of video and media formats, with each device often supporting additional formats on top of this.

As you can see in the Developer Guide, video file formats supported include 3GP, MP4, WEBM, and MKV, depending on the format used and on which platform level the user has installed.

Audio file formats you can expect built-in support for include MP3, MID, OGG, and WAV. You can stream media on Android over RTSP, HTTP, and HTTPS (from Android 3.1).

4. Add Playback Controls

Step 1

We've implemented video playback, but the user will expect and be accustomed to having control over it. Again, the Android platform provides resources for handling this using familiar interaction via the MediaController class.

In your Activity class's onCreate method, before the line in which you call start on the VideoView, create an instance of the class:

Next, set it to use the VideoView instance as its anchor:

And finally, set it as the media controller for the VideoView object:

When you run the app now, the user should be able to control playback of the streaming video on Andoid, including fast forward and rewind buttons, a play/pause button, and a seek bar control.

The seek bar control is accompanied by the length of the media file on the right and the current playback position on the left. As well as being able to tap along the seek bar to jump to a position in the file, the streaming status is indicated using the same type of display the user will be accustomed to from sites and apps like YouTube.

As you will see when you run the app, the default behavior is for the controls to disappear after a few moments, reappearing when the user touches the screen. You can configure the behavior of the MediaController object in various ways.

See the series on creating a music player app for Android for an example of how to do this. You can also enhance media playback by implementing various listeners to configure your app's behavior.

5. Using MediaPlayer

Step 1

Before we finish, let's run through an alternative approach for streaming video to Android using the MediaPlayer class, since we used it in the series on creating a music player. You can stream media, including video, to a MediaPlayer object using a surface view. For example, you could use the following layout:

We will refer to the SurfaceView in the implementation of the Activity class.

Step 2

In your Activity class, add the following interfaces:

Your IDE should prompt you to add these unimplemented methods:

We will add to the surfaceCreated and onPrepared methods.

Step 3

To implement playback, add the following instance variables to the class:

In the Activity's onCreate method, you can then start to instantiate these variables using the SurfaceView object you added to the layout:

Step 4

In the surfaceCreated method, set up your media playback resources:

Finally, in the onPrepared method, start playback:

Your video should now play in the MediaPlayer instance when you run the app.

You're all set, now you can start streaming videos on Android.
