Android standalone doesn't load images

Hey everyone, I’ve been stuck on an android standalone build issue for a couple days now. Would really appreciate any tips. I’ve read through all the similar issue reports but those fixes don’t seem to help anymore.

This is how I’ve been loading assets (works fine in Expo and iOS standalone) this.backgroundTexture = await ExpoTHREE.loadAsync(Asset.fromModule(require('../assets/textures/white_marble.png')));

On android standalone, the image just shows up blank. App doesn’t crash though, like other devs reported in 2019.

I also tried: this.backgroundTexture = await ExpoTHREE.loadAsync("https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png");

but no luck! Url also doesn’t load.

I ran in to this issue as well in Android release variants. What ended up working for me is [this modification] - change the extension of the image to .xpng (otherwise on Android, it gets moved to the drawables folder instead of raw, and expo loader expects them in raw.

With this change in place, the following code should work (using your example above):

const assetFromMod = Asset.fromModule(require('../assets/textures/white_marble.xpng'))
if (assetFromMod.type === 'xpng') assetFromMod.type = 'png'; // just in case, switch back to .png
await assetFromMod.downloadAsync()
let tex = new TextureLoader().load(assetFromMod.localUri);

you should then be able to use tex with any material. This change also works with iOS too, so you don’t need any platform specific logic.

There are a few issues filed with the main expo/expo repo related to this so hopefully is a temporary workaround.

I’m not sure how much I will be able to help with that error. I don’t have any experience with debugging Android - I only found the trick with changing extensions for images after many hours of searching and it worked for me so I thought I would share. In your adb logcat I notice libexpo-gl.so not found on /data/data/com.jackz_sparoow.SampleApp/lib-main and that seems like it could be related. If your app can’t load libexpo-gl or doesn’t have it linked you would have a lot of problems with texture loading. But again I have very little experience with debugging these sorts of problems.
