What happened?

When passing a number in the source property the video won't load on Android release builds. On debug builds it does work, and on iOS it always works.

I've retrieved the number value like this (I've also tried require('./asset.mp4')):

import VideoAsset from './asset.mp4';

Unfortunately, it won't show a video in my app and using Android Studio I'm seeing the following error:

Playback error

Adding logs in the getUriFromAssetId function in Source.kt does indicate that it found an identifier:

identifier: 2131820554

The result of getUriFromAssetId is:

android.resource:/2131820554

Unfortunately, I'm not proficient in Kotlin or Android native stuff, so I don't know how to continue from here.

I'm 100% sure that the assets are actually bundled with the app, because when passing the VideoAsset to the source of an Image element from expo-image it actually shows the first frame as image.

Reproduction Link

No response

Reproduction

Step to reproduce this bug are:

1. Add an mp4 asset.
2. Import or require the asset by relative path.
3. Use the result of the import or require as source parameter.
4. Create an Android Release build (Debug works fine)
5. No video is displayed on Android

Changed the return of getUriFromAssetId to

return Uri.Builder().scheme(ContentResolver.SCHEME_ANDROID_RESOURCE).authority(packageName).path(identifier.toString()).build()

as in the Android documentation the package name is also added optionally, resulting in android.resource://com.myapp.android/2131820552, which does look like a more valid URI, but unfortunately it doesn't result in a playing video.

Also tried

return Uri.Builder().scheme(ContentResolver.SCHEME_ANDROID_RESOURCE).authority(packageName).path(uriString).build()

resulting in android.resource://com.myapp.android/src_assetcache_asset_10, but this also doesn't work.

ur encountering this. its loading ur source as an httpDataSourceFactory and that happens when cache is enabled.

Ahaa! Thanks, disabling the cache for local assets fixed it indeed!
