How to Effectively Use MediaPlayer with OnCompletionListener in Android Studio

Are you experiencing issues with getting your audio application to respond correctly to button clicks and play multiple audio files in succession? Many beginners face challenges when integrating MediaPlayer with OnCompletionListener in their Android projects. In this guide, we’ll explore the common pitfalls and provide a clear solution that will help you develop a fully functional audio player application.

The Problem

In Android development, particularly when handling audio playback using MediaPlayer, it's not uncommon to encounter issues. As a beginner, you might find that your buttons don’t respond, or the audio files don’t play correctly. This was the case for a user who attempted to utilize multiple MediaPlayer instances:

MediaPlayer Instance: Each time they wanted to play an audio file, they created a new instance of MediaPlayer which caused problems.

Button Clicks: They forgot to set OnClickListener for their buttons, rendering them non-responsive.

With these issues in mind, it's essential to understand how to create a more efficient and functional solution.

The Solution

To build a working audio player that plays multiple audio tracks with seamless transitions, we need to make a few adjustments to the code. Here’s how to proceed:

1. Setting Up Your Player

You should initialize your MediaPlayer instance properly, ensuring that it only creates one instance instead of multiple.

2. Setting OnClickListeners

Don’t forget to set OnClickListener for each button. This ensures that when your button is clicked, it triggers the intended action.

3. Managing the Playback

Instead of creating a new MediaPlayer instance every time, use the existing instance and manage the data source. This approach improves performance and decreases the likelihood of errors.

Playing Music

Here is how to implement the playMusic method to reuse the MediaPlayer instance:

4. Handling Completion Events

Use the OnCompletionListener to play the next track seamlessly. This function should be set when you initialize the MediaPlayer.

5. Updating the UI

Lastly, you should update the UI to reflect the current state of playback. Ensure that your buttons reflect whether a track is playing or paused.
