*A fork of [Dylan McIntyre's CameraKit-Android library](https://github.com/gogopop/CameraKit-Android), originally a fork of [Google's CameraView library](https://github.com/google/cameraview). Right now this is like CameraKit-Android, but with *a lot* of serious bugs fixed, new sizing behavior, better orientation and EXIF support, new `setLocation` and `setWhiteBalance` APIs. Feel free to open issues with suggestions or contribute. Roadmap:*
- [x]*delete `captureMethod` and `permissionPolicy`, replace with `sessionType` (either picture or video) such that when `sessionType=video`, pictures are captured with the fast 'frame' method*
CameraKit is an easy to use utility to work with the Android Camera APIs. Everything at the moment is work in progress, but it works well for pictures at least.
To capture video just call `CameraView.startRecordingVideo(file)` to start, and `CameraView.stopRecordingVideo()` to finish. Make sure you setup a `CameraListener` to handle the video callback.
What to capture - either picture or video. This has a couple of consequences:
- Sizing: capture and preview size are chosen among the available picture or video sizes, depending on the flag
- Picture capturing: **you can capture pictures during a `video` session**, though they will be captured as 'screenshots' of preview frames. This is fast and thus works well with slower camera sensors, but the captured image can be blurry or noisy.
- Permission behavior: when requesting a `video` session, the record audio permission will be requested. If this is needed, the audio permission should be added to your manifest or the app will crash.
Focus behavior. Can be off, continuous (camera continuously tries to adapt its focus), tap (focus is driven by the user tap) and tapWithMarker (a marker is drawn on screen to indicate focusing).
How to capture pictures, either standard or frame. The frame option lets you capture and save a preview frame, which can be better with slower camera sensors, though the captured image can be blurry or noisy.
Either picture or video. This tells the library which permissions should be asked before starting the camera session. In the case of 'picture', we require the camera permissions. In the case of 'video', the record audio permission is asked as well.
Please note that, if needed, the latter should be added to your manifest file or the app will crash.
You can handle permissions yourself and then call `CameraView.start()` once they are acquired. If they are not, `CameraView` will request permissions to the user based on the `sessionType` that was set. In that case, you can restart the camera if you have a successful response from `onRequestPermissionResults()`.
You can setup the `CameraView` dimensions as you wish. Default behavior is that if your dimensions don't match the aspect ratio of the internal preview surface, the surface will be cropped to fill the view, just like `android:scaleType="centerCrop"` on an `ImageView`.
If `android:adjustViewBounds` is set to true the library will try to adapt the view dimension to the chosen preview size. How? All dimensions set to `wrap_content` are streched out to ensure the view holds the whole preview. If both dimensions are `wrap_content`, this is exactly like `android:scaleType="centerInside"` on an `ImageView`.
