Build standalone Android app

Hello,

I’m trying to prepare the release build of the app in order to publish on Google Play.
In my case I don’t want to publish the js bundle on any server, so I’m not running expo publish.

When installing the apk on the device I’m getting the error “Could not load embedded manifest…” after the splash screen.
This is exactly as explained here:
https://github.com/expo/expo/issues/1916

I just wanted to ask as of today what is expected to be in embeddedResponses in AppConstants.java ?
And what to return in publishedUrl in MainActivity.java ?

The exception I’m seeing is triggered here:

github.com

expo/expo/blob/875418febf34a8e8506cf82c98af4d531addd81c/android/expoview/src/main/java/host/exp/exponent/ExponentManifest.java#L341


      
            requestBuilder.header("Expo-JSON-Error", "true");
            String finalUri = requestBuilder.build().url().toString();
          
          
  String embeddedResponse = mExponentNetwork.getClient().getHardCodedResponse(finalUri);
          
          
  try {
              JSONObject embeddedManifest = new JSONObject(embeddedResponse);
              embeddedManifest.put(ExponentManifest.MANIFEST_LOADED_FROM_CACHE_KEY, true);
              fetchManifestStep3(manifestUrl, embeddedManifest, true, listener);
            } catch (Exception e) {
              listener.onError(new Exception("Could not load embedded manifest. Are you sure this experience has been published?", e));
              e.printStackTrace();
            }
          }
          
          
private void handleManifestResponse(ExpoResponse response, String manifestUrl, String httpManifestUrl, ManifestListener listener, boolean isEmbedded, boolean isCached) {
            if (!response.isSuccessful()) {
              ManifestException exception;
              try {
                final JSONObject errorJSON = new JSONObject(response.body().string());
                exception = new ManifestException(null, manifestUrl, errorJSON);

Thanks a lot

P.S: I can run the app in debug and I know how to generate the bundle using expo export

The only reference I’ve found in the documentation is:
https://docs.expo.io/versions/latest/expokit/advanced-expokit-topics/#configuring-the-js-url

It’s not clear to me the changes needed in order to load the manifest and the bundle embedded.

Anyone has ever done that ? Or is it just not possible in Expo to eject an Android app that is not going to hit the server for the bundle ?

Thanks

Found why it was not working, it’s because the urls in embeddedResponses need to match the ones in shell-app-manifest.json
