How to Fix Audio Glitches in Android While Using MediaPlayer and SeekBar

When developing Android applications, many developers encounter issues with audio playback, especially when integrating MediaPlayer with a SeekBar. A common problem is that audio does not play smoothly and may even glitch or break while adjusting the seek bar. If you've been facing this frustrating challenge, you’re not alone.

In this guide, we will explore the reasons behind the glitches and provide you with simple solutions to ensure seamless audio playback in your Android apps.

Understanding the Problem

When using the MediaPlayer class along with a SeekBar in Android, it's essential to synchronize the audio playback with the user's interaction. The primary issue arises when audio playback and seek operations are improperly handled:

Automatic Seeking: If the audio is seeking automatically while the user interacts with the SeekBar, it can lead to glitches.

Continuous Updates: Utilizing a Timer to constantly update your seek bar may cause the audio to jump, as the MediaPlayer might attempt to seek to the current position while the user is also trying to adjust the position.

Example Code Snippet

Here’s an example of code that may cause issues:

In this example, the onProgressChanged method seeks to the new position regardless of whether the change came from user input or from the timer updating the SeekBar.

Solution: How to Fix the Glitches

The key to fixing the audio glitches is to differentiate between user inputs and the automatic progress updates provided by the Timer. We can achieve this by utilizing the fromUser parameter in the onProgressChanged method of the SeekBar.

Step-by-Step Solution

Modify the onProgressChanged Method: Ensure that you only seek to the desired position when the change is initiated by the user.

Here’s the corrected version of the onProgressChanged method:

Maintain Original Timer: The Timer can still be used, but you should ensure that it doesn't interfere with the user’s input. The automatic progress updates should only affect the seek bar visually without invoking the seek operation on MediaPlayer.

Additional Tips

Consider Alternative Approaches: Instead of using a Timer, you might consider using a Handler to update the seek bar, which can provide more control and avoid negative interactions.

Thorough Testing: Always test your audio and seek bar integration on various devices to ensure a smooth experience for all users.

Conclusion

By implementing the suggested changes, you should be able to eliminate the audio glitches caused by improper seek operations while using MediaPlayer with a SeekBar in your Android applications. Remember, properly distinguishing user interactions from automatic updates is crucial for a seamless audio experience.
