On this week's episode, we break down how camera APIs work in Android and why third-party camera apps just can't match the features and quality produced by the stock camera. Long story short, it's a mess. What gives? And what's being done about it? We're joined by https://github.com/MHShetty (Mohit Shetty), a developer behind https://play.google.com/store/apps/details?id=app.grapheneos.camera.play&hl=en_US&gl=US (Secure Camera), the camera app on GrapheneOS and available to everyone on the Play Store. 01:48 - How does hardware fragmentation make camera app development on Android inherently more challenging than on iOS? 03:52 - Was there anything Google could have done in the early days to make things better? 08:21 - Why don't OEMs bother with making sure third-party camera apps work the same as the stock camera app? 12:27 - What are some features that OEMs can't expose to third-party camera apps through Android's camera API? 17:20 - How does Android's camera architecture work? What is Camera HAL 3? 20:23 - How will Google Requirements Freeze (GRF) affect camera HAL versioning? 24:11 - How do third-party camera apps interface with multiple cameras? 29:28 - What is the Camera2 API? 32:52 - What is CameraX and what can (and can't) it do?
