Branch subscribe not working

Expo SDK
1

Hi, Im having trouble getting Branch.io to work on android in the standalone builds. I`ve tried expo 23/24 but both dont work.

Branch.subscribe(({ error, params }) => { Alert.alert(“hallo”); });

Opening the app through the branch link wont trigger the subscribe.

Are you importing branch using Expo.DangerZone.Branch?

Im importing it exactly as in the comments. I also watched the logcat and it seemed fine.
Should I be able to rebuild the behavoiur with the Linking Module ?

Not sure what this means exactly. Can you share your code?

Hi @jesse, thanks for your reply. I am currently working with @trunken on this app and after putting it back for a while we still could not solve this problem.

This is all the code we added involving the Branch SDK.


  componentDidMount(){
    Linking.addEventListener('url', this._handleUrl);
    Expo.DangerZone.Branch.subscribe((bundle) => {
      if (bundle && bundle.params && !bundle.error) {
        console.log(bundle);
      }
    });
  }

This code is placed in the first component of the App.

As you may see, we also tried out the Linking module after Branch wasn’t working. This actually recognizes the link but since Branch only passed the link_click_id we didn’t get the link-data yet with this.

We checked the branch-key in the app.json multiple times and yet tested the behaviour on multiple Android devices (App Links enabled in the Branch link settings). Unfortunately we are not able to test on ios currently.

Do you have any further ideas which could be the problem?
Thanks,
Julius

in the adb logcat we see this error:

overall looks very similar to this issue
