Hey everyone,
To elaborate more on Rob’s comment, we’ve been hard at work to get Marshmallow support done. The biggest challenge that’s come from it is supporting the new Runtime permission model. It’s a large breaking change to how Android apps are developed and supporting it in a way that’s easy-to-use, powerful, and cross-platform has required significant additions/changes to Corona. Unlike iOS where management of privacy settings is mostly handled by the OS, it’s the developer’s responsibility to handle this on Android.
One change that’s been made related to cross-platform concerns is the behavior of media.hasSource(media.Camera) on iOS, detailed here. By that same token, once Marshmallow support is complete, your current Corona apps should work with minimal changes.
