Android OutOfMemoryError When Using setAudioSource with Large Audio File (3GB, 56 Hours)

[Mc231]

Which API doesn't behave as documented, and how does it misbehave?

The setAudioSource method does not handle large audio files as expected on Android devices. When attempting to use setAudioSource(AudioSource.file(filePath)) with a very large audio file (approximately 3GB in size and 56 hours in duration), it results in an OutOfMemory error.

Minimal reproduction project Provide a link here using one of two options:

1. Fork this repository and modify the example to include a large audio file (3GB, 56 hours duration) in the assets or as a local file that the app attempts to load.

To Reproduce (i.e. user steps, not code) Steps to reproduce the behavior:

1. Clone the official JustAudio repository.
2. Open the project in Android Studio or another IDE that supports Flutter.
3. Navigate to the main audio player setup in the example.
4. Replace the existing audio source ("nature.mp3") with a large file (approx 3GB, 56 hours duration) either by placing it in the assets folder or referencing it as a local file.
5. Run the application on an Android device.
6. Attempt to play the large audio file.
7. Observe that an OutOfMemory error occurs, preventing the audio from being played.

Where is the forked repository?

Thank you for looking into this. There's no need to fork the repository to reproduce the bug; you can use the unmodified example provided in this repository.

[ryanheise]

I'm asking for the fork because the instructions I provided you on submitting a bug report required it. You did not follow those instructions, so I am asking for you to do so. The minimal reproduction project section still makes reference to a "fork" which simply was not provided. If you want to provide an audio file that reproduces the bug, you may also do that. You did neither.

Also, the next section on "To Reproduce (i.e. user steps, not code)" contains instructions for modifying the code which is EXPRESSLY against what the instructions say.

I'm closing this as an invalid issue. I'll reopen it if you fix it and add a comment below to notify that it is done.
