[http] Requests fail with SocketException when flutter app goes in to background

[KingRial]

Just wanted to let you know that this issue is still present on android devices: #877

I discovered the problem while using the openid_client (https://pub.dev/packages/openid_client).
I configured the authentication process to use an external browsers (See appsup-dart/openid_client#128 for more details) and this is what happens:

• When the authentication process starts the App goes in background and open a browser to desired authentication server URL
• When you log in the browser will be redirected to localhost:4000 with all the relevant data
• However the openUrl on

  http/pkgs/http/lib/src/io_client.dart

  Line 114 in ef05b37

  var ioRequest = (await _inner!.openUrl(request.method, request.url))

  fails with the "ClientException with SocketException: Failed host lookup: 'xxx.yyy.zzz' (OS Error: No address associated with hostname, errno = 7)" since the App has been put on background (and the browser is still on foreground)

If you use an inApp webview the problem doesn't occur (since the app is still on foreground)

Hi @KingRial

Could you try using package:cupertino_http to see if you can still reproduce?

Hi @brianquinlan,

just wanted to point that this issue is related only to Android environment; on Apple/iOS everything is fine.
I could try using the package:cupertino_http but I don't understand how on Android this could change anything.

Should I still try to reproduce it with package:cupertino_http?

No, sorry. On Android, could you try to reproduce with package:cronet_http?
