This one was built around a client requirement so isn't currently very feature-filled but we'll be expanding it later on.
Android Custom Camera Preview adds functions to show a full-screen camera preview and overlay it with image + text content, and/or take individual photos while running. Photos are saved to device cache so they can be processed by your Corona app.
The purpose of this plugin is to allow Corona app code to continue to run while the preview is displayed, to allow a preview to be displayed in a way where bespoke elements can be drawn over the top (frame, crosshair, instructions, feedback-data etc), and to provide a mechanic for capturing an image without relying on the user actually taking a snapshot through the native camera app. All things that out-of-the-box just isn't possible for Android developers.

At the moment, the app only supports back-facing camera and doesn't include video recording abilities. We plan to eventually add both in and may do so sooner if there's enough demand for it, so please do get in touch if this is a deal-breaker for you.
