expo build:android produces APK with missing image assets

Forgive me if this is a naive question but I cannot for the life of me figure out why my APKs built with the expo build:android command are missing some art assets. They’re all used in the JSX in a manner similar to this:


The path is correct and they all show up when debugging with expo start.

I have noticed the following messages when running expo build:android:

“Uploading assets
No assets to upload, skipped.”

Could it be that Expo is not detecting the images? If so, can I force a refresh somehow?

Thanks in advance.

Hey @evaunit02,

Are you pre-fetching the assets with AppLoading at all? Also, you may want to explore bundling your assets to increase start-up time performance.


Thanks so much for your reply. I genuinely appreciate the help.

I wasn’t prefetching the assets with AppLoading, no. However, I just tried it and it didn’t work for me. Granted, I didn’t prefetch in the App object itself. I prefetched them in my first Screen object instead but I followed the example you linked to.

I also tried bundling the assets as described by your second link. However, when I do that, uploading the APK generated by “expo build:android” to Google Play fails with an undescribed error.

However, I couldn’t bundle using an asterisk as in the documentation example, “assets/images/*” The app would fail to load in that case when I launched it with “expo start”. When I removed the asterisk (“assets/images/”) the app would load without error. I’m not really sure what was going on there.

For anyone else who comes across this problem, I finally discovered the solution: Expo can’t properly run on React Native itself. It runs on a custom fork of React Native which can be found here:

For Expo 32.0.0, your npm dependency in package.json should read:

"react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz"

Perhaps Expo should look for an identifier for their fork of RN when “expo start” is run. Otherwise, Expo seems to run just fine until wonky things happen.
