audio_service breaks some app links when used with the app_links package [android]

[Aulig]

Documented behaviour

Not documented.

Actual behaviour

I use the app_links package to make it so links to my website (regular https links, not deep links with a custom scheme) get opened inside the webview of the app.

Most of the time the app links work completely fine, but we noticed that when a user is at checkout and tries to log in with a magic link (login link sent via e-mail), the webview breaks (becomes either unresponsive or blank).

This is related to audio_service because the issue no longer appears when I don't inherit from AudioServiceFragmentActivity. Normally I have

class MainActivity : AudioServiceFragmentActivity() {

// with my own custom onCreate function
}

but when I use

class MainActivity: FlutterFragmentActivity()

the bug no longer occurs.

Runtime error

No error logged.

Reproduction steps

These are modified (from a regular use case) instructions so you don't have to register for an account, so they might seem a bit weird.

Do once:

1. Send yourself an e-mail to a Gmail account that you can access on your test device. The email should include the link to the website we're showing in the WebView. You can use the link https://patriciaelias.com.br/loja/
2. Install the app
3. Open the app info screen (where you can uninstall the app). Scroll down to "open by default" click "Add link" and select the patriciaelias link.

Do every time you want to reproduce the error:

1. Open the app
2. Click "Adicionar ao carrinho" on the first product on the home page
3. Click the green "Finalizar Pedido" button
4. Enter "[email protected]" in the e-mail address field and click Avancar
5. Close the app (keep it open in the background/multitasking)
6. Go into gmail and click on the link in the e-mail you sent yourself
7. The webview will now be frozen (doesn't react to gestures) or completely blank.
8. To reset/fix the app afterwards, uninstall it or clear its data.

Sorry that the steps to reproduce are so complicated, I wasn't able to simplify them further yet because I don't understand how audio_service interacts with deep linking.

This issue does not follow the issue template. If you click the "New issue" button, it should require you to answer a number of different questions.

[Aulig]

Hmm, I don't see anything like that unfortunately

[ryanheise]

Hmm, I'll have to look into that.

My template chooser config file looks correct so I'm not sure what happened. Maybe it's a GitHub fault...

Anyway, the link is here:

At this point, you can either submit that issue to GitHub or you can copy and paste the formatted issue text from there into THIS issue to avoid creating multiple issues. You can also edit your initial post above to include the required information.

Thanks for letting me know @ryanheise ! I've updated the issue now.

Hi @ryanheise - hope I'm not bothering you, just want to make sure that you saw the updated issue. Let me know if there's any issues with reproducing the bug. I appreciate all the work you put into this plugin.

If you have any background info on what audio_service does regarding deep linking, that'd help me with investigating the issue further too. Thank you!

[ryanheise]

I did, I have just been busy catching up with things after having the flu for 3 weeks, so I am slowly working my way to this.

[Aulig]

Thanks for letting me know! Sorry, didn't mean to pressure you. Happy to hear you're doing better again!
