Android Permission Behaving Strangely

[DanielNovaesDias]

Tested in Android 13 Real Device.

If you start the scan for the first time, it will ask for camera permission, but if the user selects the option to only allow "one time" the plugin never shows the prompt again, when it should.

Now, if the user opts for don't permit then the modal pops up alerting the user to go to settings, works fine.
but then, if the user selects for android to prompt him everytime, when he tries again to scan, the permission will still show as denied, only going away if he chooses to always give permission.

this is some strange behavior which is not inline even with the camera plugin which shows "prompt" | "granted" | "denied" accoardingly.

I checked the repo and it just throws error based on the outsystem plugin. maybe it's an error by the third party plugin? one of the downsides of choosing to use a third party...

Hey @DanielNovaesDias thanks for opening this issue.

Indeed this plugin could use a requestPermissions and checkPermissions like in camera and other capacitor plugins.

I'll write some additional remarks below

but if the user selects the option to only allow "one time" the plugin never shows the prompt again, when it should.

The "one time" does not mean necessarily mean every time a scan is made a new permission request is made, it means permission will be granted temporary, usually while the app is open. This is controlled by the system, more info in the docs - https://developer.android.com/training/permissions/requesting#one-time

if the user selects for android to prompt him everytime, when he tries again to scan, the permission will still show as denied

I can't be fully sure if this is a bug or intended, because the "one time" access in settings probably doesn't translate to a granted permission, hence why the popup doesn't disappear, but I may be wrong here.

I checked the repo and it just throws error based on the outsystem plugin

Most native logic comes from a native library we have, that's shared in other plugins, maybe that's what you're referring to? https://github.com/OutSystems/OSBarcodeLib-Android

Hope it helps.
