How to Pass a Video Link from One Activity to Another in Android Using Kotlin

In Android development, it's common to need to share data between different activities. One common requirement is passing a video link from one activity to another, particularly when you want to play the video in a media player like ExoPlayer. In this guide, we will explore how to achieve this using Kotlin.

Understanding the Problem

You've implemented a button in your first activity that should pass a video link to your second activity. However, when you retrieve the video link using intent.getStringExtra in the second activity, your app crashes. This issue often arises due to the variable being accessed before it's initialized properly.

Let’s break down the solution step-by-step.

Step-by-Step Solution

Step 1: Passing Data with Intent

In your first activity, you successfully create an Intent and put the video link as an extra using intent.putExtra(). Here’s a recap of your implementation:

Step 2: Retrieving Data in the Second Activity

You need to ensure that you retrieve the video link from the intent after the activity has been created. This means you should move the retrieval of the video link inside the onCreate method of the second activity, MainActivity. Here's the corrected code:

Step 3: Handling the Media Player

With the correct retrieval of the video link, you can now use it to initialize your ExoPlayer. Ensure that your media player is set up to handle the videolink as shown in the previously provided code.

Debugging Tips

Check Logs: If your app crashes, check the logs in Logcat for any exceptions. This will help you identify the exact line causing the issue.

Ensure Permissions: Don’t forget to check permissions if your app needs internet access to stream video.

Conclusion

Passing a video link between activities in an Android application is a straightforward process when you follow the correct steps. By ensuring that you retrieve the intent data inside the onCreate method of your second activity, you can avoid possible crashes and ensure smooth functioning.

Now that you know how to do it, you can further enhance your media playback experience by customizing your player controls and layouts! Happy coding!
