Our Android Custom Camera Preview plugin adds camera preview support and functions to overlay the feed with a bespoke graphic (crosshair, frame, etc) and custom texts.
The plugin also provides a function to instantly capture a photo without launching the native camera app. Photos are saved to device cache and a filename passed back to your Corona code for custom handling.
Version 2 has been completely rewritten with tonnes of code optimisations for better stability, performance, support for newer devices, and better quality previews and captures.
Version 2 also adds support for front facing, externally connected, and grouped camera configurations. This plugin is no longer restricted to just back facing cameras.
