To plugin users

Hello,

Sorry that the plugin didn’t work well for all of you. Unfortunately, I don’t have testing devices and time for investigations and fixing issues at the moment. Please feel free to create new tickets. I would be even more grateful for pull requests. I’m not abandoning the plugin and promise to merge contributions with fixes and new functionality, hence I would kindly ask for help with the development 🙂

Thanks in advance!

For Android

Camera permission will be automatically added to your AndroidManifest.xml. Do not forget to request this permission.

  )
