CameraView

This is not an official Google product.

CameraView aims to help Android developers easily integrate Camera features.

Requires API Level 9. The library uses Camera 1 API on API Level 9-20 and Camera2 on 21 and above.

API Level Camera API Preview View
9-13 Camera1 SurfaceView
14-20 Camera1 TextureView
21-23 Camera2 TextureView
24 Camera2 SurfaceView

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)

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.
