twa has assetLinks but is still opening with address bar about svgomg-twa

[tomsawada]

@alexpryshchepa > 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.

I owe you a beer. ;)

@andreban
note: add to home screen works correctly(correct launch icon and no address bar). But app apk on the path does not. How should i debug.

[andreban]

@pranaykothari It seems https://xyz.in redirects to https://www.xyz.in. The first is listed to be verified in the app, the second is not. Try changing the hostName to www.xyz.in.

PS: This sounds like a great question for Stack Overflow. Could you please post it there? I'm happy to provide the answer there.

[bantyK]

Hey @andreban thanks for the response. I was able to just fix it. In my case it was an issue related to signin config. I was running my app in debug version but my app was signed only for release version.

However, I think information like this should be added in the documentation.

Hey, I'm one of the maintainers for this and TWA related stuff.

You can use Peter's Asset Link Took to generate your Digital Asset Links file for an Android app. Just install it on your device and pick your package.

@andreban

I did not publish my app yet because I'm afraid this behaviour is happening for all users.

My question is if the url bar will disapear after I publish my app on Play Store and it is expected when I'm installing my app locally on my device?

Bellow the image using this project example and installed the apk directly from Android Studio on my device:

And just to your understand after I added it as my home screen icon and access throught this it is not ocurring:

I also tested in 2 devices: Azus zenfone 2 (Android 5.0) and Samsung J5 Prime (Android 8.0)

Hi all,
a heads up: if Firefox is set as a default browser on the Android settings of your device, then the address bar will show up regardless.
In my case assetlinks and signatures were all configured correctly, but the address bar went away once I actually set Chrome as default browser.

I hope that helps.

[andreban]

@bantyK issues with showing the top are usually related to the misconfiguring Digital Asset Links. I haven't a case where the setup is correct and the top bar is showing. I'm happy to take a look on why it's not working for you, if you can share the APK with me.

@leandro2ki we have discussed this offline. Could you please confirm the issue has been fixed for you?

I'm closing this issue, as it's misleading folks to believe there's an issue causing the top bar to show.

[andreban]

This section was recently added to the documentation for the sample. Does it help?

[andreban]

Would you be able to link to your assetlinks.json file?

[navinSing]

yes i am able to access
https://a.b.com/.well-known/assetlinks.json in browser

Any idea what is wrong.(What all things i should verify)
I still see address bar. Also the custom icon was not showing up.

i rebuild the app and published again.. but still showing up the address bar

please help

[andreban]

Hi @navinSing, if you have the APK published somewhere, I'd be happy to take a look in it and help understand what is going wrong.

[navinSing]

Please find the apk

app-release.zip

[andreban]

The APK and the site are configured correctly, and I'm able to see it working on my device.

Could you confirm the Android version (Settings > System > About Phone) and the Chrome version (chrome://version) you have installed?

[navinSing]

yes .. may be ..

Android version (Settings > System > About Phone)
7.0 NRD90M

Chrome version (chrome://version) you have installed?
72.0.3626.105

[navinSing]

I am available on hangout : [email protected]

[kimuradev]

I'm getting the same issue here. I'm still seeing my url bar from my app and when I add it to home screen then url bar disapear. Anyone has a solution for it?

[andreban]

@leandro2ki Is there anywhere I can download the APK to check it out?

[andreban]

@leandro2ki It seems the assetlinks validation is failing. Configuring Digital AssetLinks has a few moving parts. If you can make the APK or the source code available I can check if there are any issues with the configuration. Otherwise, we need to confirm its a bug and create an issue in Chrome. Feel free to share the APK on e-mail, if that helps. My e-mail is the same as my Github username, but @google.com

[kimuradev]

@andreban I sent you an e-mail with my apk. I'll appreciate if you could take a look there. Thanks.

[bantyK]

I am still facing this issue ? Is this resolved ? I am facing this issue on Samsung S7 edge device but it is working fine in 1+ 5T

[pranaykothari]

signin

Hi @bantyK , how did you fix the issue related to signin config you mentioned? We have the exact same issue, but can't figure the solution. In our case we have a SHA256 fingerprint that we use to sign the app and publish to app store. The same key is used in digital asset link, and the TEST succeeds. Unfortunately, the app still opens up with the address bar.

@andreban I believe the documentation link you mentioned is good, but we still could not resolve the issue mentioned above.

Any insight will really help.

Thanks,
Pranay.

[bantyK]

Hey @pranaykothari, in my case only the release flavor of the app was signed and I was running the app in debug version which is causing the address bar to show up. Try to run the app in the release version and it should work.

[pranaykothari]

@bantyK I verified that we are running a release signed build (and the same is published in app store) using the following command, and it does mention APK is in the release mode.

command: jarsigner -verify -verbose -certs your_apk.apk

(command reference)

Also, here is the relevant content of the app/build.gradle file.

   buildTypes {
        release {
            minifyEnabled true
            debuggable false
        }
    }

And here is the twamanifest info:

def twaManifest = [
    applicationId: 'in.xyz.app',
    hostName: 'xyz.in', // The domain being opened in the TWA.
    launchUrl: '/', // The start path for the TWA. Must be relative to the domain.
    name: 'XYZ', // The name shown on the Android Launcher.
    themeColor: '#FFCD59', // The color used for the status bar.
    backgroundColor: '#ffcc99' // The color used for the splash screen background.
]

I wonder what are we still missing?

Pranay.

[andreban]

@pranaykothari Is the URL you are trying to open https://xyz.in/ ? That URL returns connection refused for me. Even though http://xyz.in/ works, TWAs require HTTPS.

[pranaykothari]

@andreban Your answer is spot on! That seems to be the issue. Changed the hostname to www.xyz.in in app/build.gradle and it stops showing the address bar. Appreciate your help.

Created a stack overflow question as requested:

Download (this app)[ https://www.google.com/url?sa=t&source=web&rct=j&url=https://play.google.com/store/apps/details%3Fid%3Ddev.conn.assetlinkstool%26hl%3Dgsw&ved=2ahUKEwi37L_asr_nAhWhqHEKHbICBt8QjjgwAXoECAYQAQ&usg=AOvVaw2GMG02BfMumgpPtbe9_N-a] onto your phone, open it and select your TWA installed from the play store. It will give you the contents of the digital asset link file that you need to put on your server. The issue is that you're using a different key for your debug builds and the play store - probably because you're using play store signing. This is fine - just make sure your digital asset links file includes both signatures.

Hi @andreban,

I have verified my web asset linking on
https://developers.google.com/digital-asset-links/tools/generator
and SHA fingerprint from
https://play.google.com/store/apps/details?id=dev.conn.assetlinkstool

I have done asset linking with 5 servers and observing weird things happening with my app.

1. On one device 2 different domain URLS are working fine but the other 3 are showing up with URL bar.
2. On one device all 5 URLs are showing up with URL bar.
3. Also, My standalone sample that means a project from which I use to create an artifact for my main app & integrate it for production. In that sample app, everything is working perfectly in terms of hiding URL.

Can you please help me?

Initially, we tested it on the sample & everything worked perfectly & everyone was excited for its integration it into the main app but now we are facing weird things & near to our production deadlines :(

This repository has been deprecated and we're not actively looking into issues here. I'd recommend asking questions on StackOverflow, on the specific trusted-web-activity tag or, if this is a bug, filing against https://github.com/GoogleChrome/android-browser-helper

Thank you So Much . I was having the same issue

[skolhustick]

For anyone using bubblewrap-cli and still confused about how to do this :

1. Go to your Google Play Console and click on your app to open the app's Dashboard
2. Then on the left menu go to App integrity and copy the SHA-256 certificate fingerprint under App signing key certificate
3. In your terminal, enter command bubblewrap fingerprint add {SHA-256-that you copied}. E.g : bubblewrap fingerprint add 43:51:43:a1:b5:fc:8b:b7:0a:3a:a9:b1:0f:66:73:a8
4. Bubblewrap will produce a file called assetlinks.json
5. Host this file on your website so that the directory is https://yourdomain.com/.well-known/assetlinks.json
6. The address bar should disappear now. I reinstalled my app to see the update. I DID NOT need to reupload another app bundle.

Hope this helps.

Thank you for saving my sanity @GF-. (PS it also works if you set Edge as the default browser. Guess Chromium is needed.)
