Ionic 4 support? about cordova-plugin-openalpr HOT 3 CLOSED

This package is not actively maintained at the moment, so I am not 100% sure. However it doesn't look like something changed for Ionic Native modules. Are you using the Ionic Native module in combination with the @ionic-native/camera module?

I think your problem is not related to Ionic, but to the OpenALPR settings. Can you share more about your usecase / config?

Hi iMicknl,

I'm using this plugin in ionic v4. Plugin installed successfully but got error while making the build for android. Here are the errors:

Anyone got this working on Ionic 4?

I'm taking the photo but the result of the scan is not returned.

Did you successfully installed the plugin and made build successfully? Because After plugin installation in ionic v4 I'm not able to make the build.
