Camera Controller

CameraX facade designed to reduce boilerplate code for simple image capture use cases.

Features

• Switch between front and back cameras
• Automatic device rotation detection for correct EXIV rotation metadata
• Flash modes
• Pinch to zoom
• Tap to focus
• Camera-related events callback for wiring with UI

Requirements

• Java 8+
• Android API 21+

Setup

Add a dependency

implementation 'com.rosberry.android:camera-controller:1.0.0'

Usage

Initialize CameraController with Context:

    val cameraController: CameraController = CameraController(context)

Set preferred camera with setFrontCameraPreffered(Boolean), you can switch between front and back cameras later using switchCamera() method.

Setup controller with androidx.camera.view.PreviewView instance, CameraControllerCallback implementation to wire camera events with UI and run it using start(LifecycleOwner) method:

    controller.setPreviewView(previewView)
    controller.setCallback(cameraControllerCallback)
    controller.start(lifecycleOwner)

Control camera flash modes with setFlashMode(FlashMode) and cycleFlashMode() methods. By default cycleFlashMode() will cycle through all available flash modes for selected camera. Variety of available modes could be limited by providing desired modes to setAvailableFlashModes(vararg FlashMode) method. Note that if setFlashMode(FlashMode) argument doesn't exist in list of available modes, component will force use provided mode though it won't be available for cycleFlashMode().

To take picture call takePicture(ImageCapture.OutputFileOptions, ImageCapture.OnImageSavedCallback) or one of the convenience methods takePicture(File, ImageCapture.OnImageSavedCallback), takePicture(OutputStream, ImageCapture.OnImageSavedCallback) or takePicture(Uri, ContentValues, ImageCapture.OnImageSavedCallback).
