BlinkID.scan returns nothing in Expo detached app for Android

Hello @LoongerBuxus

Are you able to share code sample of your app or part of the code on how did you implement the return of the result?

Regards

Hi @culoi,

I'm following the usage code you show in the readme, it's just a copy paste:

const scanningResult = await BlinkID.scan(...)

But scanningResult never gets a value, the promise never resolves or rejects. No error, no information.

As far as I have researched, the module starts the scan Intent:

currentActivity.startActivityForResult(scanIntent, REQ_CODE_SCAN);

But the ActivityEventListener never gets a result.

I think this library is not compatible with Expo detached apps, so I eventually moved my app to a react-native init one and it worked smoothly.

@LoongerBuxus you mean ejected Expo apps?

It used to be a problem [#34], but it should be working from version 1.4.2 now, see #34 (comment)

@naartjie yes, in Expo terminology eject=detach.. but I can see that issue is in iOS platform, and mine is in Android, as onActivityResult is not being called with any result from ScanIntent.

I have tried to make my own native module and the patern startActivitForResult->onActivityResult is not working with detached Expo apps.

@LoongerBuxus Ah sorry, my bad. That issue is not related at all.

I have tried to make my own native module and the patern startActivitForResult->onActivityResult is not working with detached Expo apps.

Hmm... This does sound strange, is it not something specific to your setup, rather than detached apps specifically - it seems like it would be a pretty major issue if it was the case.

@naartjie I know other people is having the same problem, maybe there is a workaround for making native modules work in detached Expo apps in Android but I opted to recreate my app with rn init as I only had the Expo Camera dependency.
