Why would be manifest not be valid?

I keep getting error like this - Manifest from is not compatible with the android platform.

Ran expo export --public-url <xyz> and then expo build:android --public-url <xyz> --no-publish --type apk

The --public-url options for export and build:* are not exactly the same. Or at least, if they are the same then you need some server-side functionality to detect the platform and redirect/serve up the correct manifest.

Easiest is to do something like this:

$ expo export --public-url https://example.com/blah/
$ rsync -avxz --progress --delete --stats dist/ example.com:/blah/
$ expo build:android --public-url https://example.com/blah/android-index.json

Note the android-index.json on the end of the build:android --public-url.

I suspect that’s the problem.

Yes, usage of --public-url is different in export vs build:android; And the --public-url for export and building are already been taken care of in this case. Also the exported files are hosted on a server. So, this won’t trouble, I think.

OK. And you can confirm that the correct manifest is served to the build server when you run expo build:android?

If so, perhaps download it yourself, open it in a text editor and check if there’s anything that looks wrong.

Yes, it is serving the android-index.json properly. There seems to be nothing wrong with json. I’m using the usual expo export --public-url ...
