Linking works on iOS but not Android

Please provide the following:

  1. SDK Version: 41.0.0
  2. Platforms(Android/iOS/web/all): Android/iOS
  3. Add the appropriate “Tag” based on what Expo library you have a question on.

I am currently trying to implement push notifications. Once the user taps a notification, the app should open on the notifications tab.

In order to do so, I added a listener, which will get an url and use Linking in order to navigate the user to the determined URL.

responseListener.current = Notifications.addNotificationResponseReceivedListener(
      (response) => {
        const url = response.notification.request.content.data.route;
        Linking.canOpenURL(url)
          .then((supported) => {
            if (!supported) {
              console.log(`Can't handle url: ${url}`);
            } else {
              return Linking.openURL(url);
            }
          })
          .catch((err) => console.error('An error occurred', err));
      }
    );
  }, []);

The URL is sent via the expo Push notifications tool in the Data (JSON) field:
{“route”: “exp://exp://130.64.155.227:19000/–/notifications”}

Which is then used to create an url in a separate file:

const prefix = Linking.createURL('/');

// NOTE: Config object can be used to map all React Navigation routes in the app
// Only notifications route is specified bc it's the only deeplinking case
const config = {
  screens: {
    tabs: {
      screens: {
        TAB_NOTIFICATION: 'notifications',
      },
    },
  },
};

const linking = {
  config,
  prefixes: [prefix],
};

export default linking;

This code works perfectly on iOS devices, however it does not work on android. This was tested for android versions 9, 10 and 11.

When a user taps on a notification, two different behaviors may happen:

  1. It runs the Linking.openURL(url), however, nothing happens,
  2. It runs the Linking.openURL(url) and a “Network response timed out” error happens.

I believe there is something wrong with the URL we are passing in the Data(JSON) field, however I do not understand why it works for iOS and not Android.

Note – The intentFilters for android were set like this:

"android": {
      "versionCode": 400000019,
      "intentFilters": [
        {
          "action": "VIEW",
          "data": [
            {
              "scheme": "https",
              "host": "*.myapp.io",
              "pathPrefix": "/notifications"
            },
          ],
          "category": [
            "BROWSABLE",
            "DEFAULT"
          ]
        }
      ]

Hey @igormafelipe, the url you’re passing has two domain values or is that just a typo? (referring to exp://exp://)

That is just a typo, sorry!
