CameraView

• This repo is forked from https://github.com/google/cameraview

CameraView aims to help Android developers easily integrate Camera features.

Requires API Level 23. The library uses Camera1 and Camera2 both.

API Level	Camera API	Preview View	Fallback Camera API	Fallback Preview View
23+	Camera2	TextureView	Camera1	SurfaceView

The library tries to use Camera2, but in case the camera device used legacy hardware (INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY), then it fallbacks to Camera1.

Features

• Camera preview by placing it in a layout XML (and calling the start method)
• Configuration by attributes
  • Aspect ratio (app:aspectRatio)
  • Auto-focus (app:autoFocus)
  • Flash (app:flash)
  • Front/Back (app:facing)
• If layout_height is match_parent, then its displays camera is fullscreen mode

Usage

<com.google.android.cameraview.CameraView
    android:id="@+id/camera"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:keepScreenOn="true"
    android:adjustViewBounds="true"
    app:autoFocus="true"
    app:aspectRatio="4:3"
    app:facing="back"
    app:flash="auto"/>

    @Override
    protected void onResume() {
        super.onResume();
        mCameraView.start();
    }

    @Override
    protected void onPause() {
        mCameraView.stop();
        super.onPause();
    }

You can see a complete usage in the demo app.
