1. Install Wowza SDK
Before you can use the Wowza Gradle plugin, you must install the Wowza GoCoder SDK for Android. The SDK provides everything you need to build live streaming applications.
- Go to the Wowza Developer Portal and sign up for a developer account.
- Download the Wowza GoCoder SDK for Android and extract the files.
2. Update build.gradle
Files
Once you have the SDK, it’s time to configure the Gradle files to include the Wowza Gradle plugin.
Project-Level build.gradle
In your project-level build.gradle
file, ensure that the Maven repository hosting the Wowza SDK is included:
allprojects {
repositories {
google()
jcenter()
maven {
url 'https://maven.wowza.com/artifactory/mobile-sdk'
}
}
}
App-Level build.gradle
In your app-level build.gradle
file, apply the Wowza plugin and include the necessary dependencies:
plugins {
id 'com.android.application'
id 'wowza-plugin'
}
dependencies {
implementation 'com.wowza.gocoder.sdk:core:1.0.0'
// Add other dependencies as needed
}
Note that you must replace '1.0.0'
with the latest version of the Wowza SDK.
3. Apply License Keys
Wowza’s SDK requires a valid license key for usage. To apply the license key, include it in your Android app’s resources or configuration files. Typically, you would store the license key in the strings.xml
file:
<resources>
<string name="wowza_license_key">YOUR_LICENSE_KEY</string>
</resources>
Make sure to replace YOUR_LICENSE_KEY
with your actual Wowza SDK license key, which you can obtain from your Wowza account.
Using Wowza SDK Features in Android
Once the Wowza Gradle plugin and SDK are properly configured, you can start integrating Wowza streaming functionalities into your Android app. Below are a few key features you can implement using the Wowza SDK.
1. Live Video Streaming
Wowza enables high-quality live video streaming directly from your Android app. Here’s an example of how to set up live video streaming:
// Initialize the GoCoder SDK
WOWZCameraView cameraView = findViewById(R.id.camera_preview);
WOWZBroadcastConfig broadcastConfig = new WOWZBroadcastConfig(WOWZMediaConfig.FRAME_SIZE_1280x720);
// Set the broadcasting server details
broadcastConfig.setHostAddress("YOUR_SERVER_ADDRESS");
broadcastConfig.setPortNumber(1935);
broadcastConfig.setApplicationName("live");
broadcastConfig.setStreamName("your_stream_name");
broadcastConfig.setUsername("your_username");
broadcastConfig.setPassword("your_password");
// Start the live stream
WOWZBroadcast broadcast = new WOWZBroadcast();
broadcast.startBroadcast(broadcastConfig, this);
In this example, replace the placeholders with your actual Wowza Streaming Engine server details.
2. Video-on-Demand (VOD)
In addition to live streaming, Wowza allows you to implement Video-on-Demand (VOD) features. This means your users can access pre-recorded content on their Android devices.
You can easily manage VOD content by integrating Wowza’s media playback features:
WOWZPlayerView playerView = findViewById(R.id.video_player);
WOWZPlayerConfig playerConfig = new WOWZPlayerConfig();
// Set the VOD server details
playerConfig.setHostAddress("YOUR_SERVER_ADDRESS");
playerConfig.setApplicationName("vod");
playerConfig.setStreamName("your_video.mp4");
playerConfig.setPortNumber(1935);
// Start video playback
playerView.play(playerConfig, this);
With this setup, your app can stream video files hosted on your Wowza Streaming Engine server.
3. Camera and Audio Configuration
The Wowza SDK also provides easy access to camera and microphone settings, allowing developers to configure the video and audio input devices programmatically.
WOWZCameraView cameraView = findViewById(R.id.camera_preview);
// Check if front or rear camera is available
if (cameraView.hasFrontCamera()) {
cameraView.switchCamera();
}
// Set audio source for the live stream
WOWZAudioDevice audioDevice = new WOWZAudioDevice();
audioDevice.setEnabled(true);
These settings ensure that your application can stream both video and audio seamlessly, with customizable camera views and audio devices.
Best Practices for Using Wowza Gradle Plugin in Android Development

2. Optimize Network Performance
Live streaming applications can be resource-intensive and heavily dependent on network quality. Consider implementing adaptive bitrate streaming to adjust video quality based on the user’s network conditions, ensuring a smoother experience on varying connection speeds.
broadcastConfig.setVideoBitRate(WOWZMediaConfig.BITRATE_ADAPTIVE);
This configuration automatically adjusts the video bitrate according to network speed and reliability, preventing buffering and interruptions during live streams.
3. Error Handling and Debugging
Integrate robust error handling in your app to capture potential streaming errors and provide feedback to users. Use Wowza’s logging and debugging features to identify issues quickly.
WOWZLog.info("WowzaStream", "Starting live stream");
try {
broadcast.startBroadcast(broadcastConfig, this);
} catch (Exception e) {
WOWZLog.error("WowzaStream", "Failed to start live stream", e);
}
This approach ensures that your app can handle streaming failures gracefully, informing users of the issue and possibly suggesting troubleshooting steps.
