'Trusted Web Activity - Address bar not hide (Chrome for Android 72)
I've followed this guide to learn how to use a Trusted Web Activity. All fine but the address bar still appear. At begin I think it was because when the app was looking for assetlinks.json the response was 404. Fixed it but no luck on removing the address bar. Am I missing something?
Chrome Version: 72.0.3626.96
Android Version: 7.1.2 (LineageOS 14.1)

Solution 1:[1]
I faced the same issue today, that's what I've learnt:
Before trying to test your android application test your statement here:
https://developers.google.com/digital-asset-links/tools/generator
Fill in domain, package and fingerprint, then click "Test Statement"
If you see
"Success! Host [your web app] grants app deep linking to [android package].", then your web app is configured the right way, and there's something wrong with your device or app.
Most likely you'll see
"Invalid input field(s)"
You can open Chrome console on the Network tab in order to look at the server output. Probably you're going to see something like
"Invalid site (URL cannot contain a path component, login information, query parameters or fragment identifiers)"
To fix this this you should put your assetlinks.json file to the root of your web app,
https://slexom.gitlab.io/.well-known/assetlinks.json
in your case.
You can checkout my sample repository. As you could see my file is accessible from https://antipovandrey.github.io/PWA/.well-known/assetlinks.json

You may have opted into having Google Play sign your releases with a key they generated, and only use your key for the upload.
If you did, go to Google Play Console Release Management -> App Signing and copy the App signing certificate SHA-256 fingerprint and put it into the assetlinks.json file.
Solution 3:[3]
when use google SHA-256 or just change fingerprint code be sure to clear chrome cache about your previous app or check cache-control of .json

In my case, I was running the app in the wrong flavour then what I used for signing. Only the release version of my app was signed in using SHA key and I was running the app in debug build.
It ran as expected when I corrected the flavor.

For those who are still facing this problem, most likely in the assetlinks.json you are using SHA256 from the "Upload certificate" and not from the "App signing certificate". You can find both certificates in Google Play Console -> Release management -> App signing.

After struggling with this for a week and finally succeeding here are my two cents:
If you opt to let Google manage your key for you, there are two keys, the
App Signing Key and the Upload key.
After following the generic steps (Setup -> App integrity -> creating the Digital Asset Links JSON)
[
{
"relation": ["delegate_permission/common.handle_all_urls"],
"target": {
"namespace": "android_app",
"package_name": "PACKAGE.NAME.HERE",
"sha256_cert_fingerprints":["APP:SIGNING:CERTIFICATE:SHA_256:FINGERPRINT"]
}
}
]
and exposing it at:
https://your.domain/.well-known/assetlinks.json
(visit the url to verify the json MUST BE A LIST/ARRAY and NOT JUST THE JSON OBJECT ITSELF or verification will fail)
Be aware that a newly built package was signed with the Upload Key and NOT The App Signing Key so assetlink verification will fail if you try to test the locally built .apk directly and the URL bar will be visible.
To really test whether linking has worked, you have to download the app from the store (Production/Internal Test/Open Test etc.) because the app is signed by google with the App Signing certificate sha_256 after the release has been successfully rolled out to the store.

FYI: I was facing this problem from a few hours and I figured this problem and the problem was I was using different package names when I generated assetlinks.json file from the actual packagename which I used while generating the android-project via bubblewrap init command.
Happy to see that url bar is now hidden and its amazing!

The same story, assetlinks.json validates successfully, but url bar exists, advises about SHA-256 from google play console not working
