APK - Cannot show bundled images

[sgoxy]

I want to generate a standalone APK with bundled assets (e.g: PNG images). The application must work with no network communication.

I read Offline support documentation and adjust the assetBundlePatterns property.

I manage to build an APK on my computer using turtle-cli tool (i.e. without using expo servers) and I can deploy it on my Android phone:

# export files
expo export --dev --public-url http://127.0.0.1:1234

# run a simple HTTP server listening on port 1234 to provide files
cd dist/
python3 -m http.server 1234 --bind 127.0.0.1

# generate the APK
EXPO_ANDROID_KEYSTORE_PASSWORD="my-keystore-password" \
EXPO_ANDROID_KEY_PASSWORD="my-key-password" \
turtle build:android \
  --type apk \
  -o dist/my-app.apk \
  --keystore-path "private/my-android-signing.keystore" \
  --keystore-alias "my-app-signing-key" \
  --public-url http://127.0.0.1:1234/android-index.json
  --type apk

# install the APK on my Android phone
adb devices
adb install -r dist/my-app.apk

Then, I disable all network connection on my phone and run the application.

The application starts but no bundled image is shown!

Besides, I get the following message when trying to display a simple image:
Error: Failed to connect to /127.0.0.1:1234

Thus, the image is not loaded from the APK ; the application tries to get it from the publish server! AFAIK, this is not compliant with the Offline support documentation.

When I unpack the APK, I can verify that the required image has been bundled in the APK file.

Am I doing something wrong? Is it a known bug? Does anybody manage to display bundled images without using an initial network connection to load them?

I have just upgraded all my project dependencies but it does not solve my issue…

Hereby some extracts of different files:

my-project/App.js file:

import React from 'react';
import { View, Image, Text } from 'react-native'
import { Asset } from 'expo-asset';


export default class App extends React.Component {

  render() {
    const imageURI = Asset.fromModule(require('./assets/images/logo.png')).uri;
    const localURI = Asset.fromModule(require('./assets/images/logo.png')).localUri;
    return (

      <View style={{ flex: 1 }}>
        <Image source={require('./assets/images/logo.png')} />
        <Text>Image URI : {imageURI}</Text>
        <Text>Local URI : {localURI}</Text>
      </View>
    );
  }
};

When running the application, the display is:

Image URI : http://127.0.0.1:1234/assets/1b5cf22759f7c052e9981fff94db78d0
Local URL :

The bundled image in the APK is : /assets/asset_1b5cf22759f7c052e9981fff94db78d0.png

my-project/app.json file:

{
  "expo": {
    ...
    "sdkVersion": "36.0.0",
    ...
    "version": "1.0.0",
    ...
    "updates": {
      "enabled": false
    },
    "assetBundlePatterns": [
      "./assets/images/*"
    ],
    "android": {
      "package": "com.mycompany.myapp"
    },
    ...
  }
}

The image that should be bundled is here: my-project/assets/images/logo.png
