Android studio new camera class

Android Studio provides a new camera class called androidx.camera.core.Camera which is part of the Android Camera API. This class provides a simple and easy-to-use interface for accessing the camera hardware and capturing images or videos.

Here are the steps to use the new camera class in Android Studio:

1. Add the Android Camera API to your project:

In your build.gradle file, add the following dependency:

dependencies {
    implementation 'androidx.camera:camera-core:1.0.0'
}

2. Create a new camera instance:

In your activity or fragment, create a new instance of the Camera class:

import androidx.camera.core.Camera;

// Create a new camera instance
Camera camera = Camera.create(Camera.CameraSelector.DEFAULT_BACK_CAMERA);

3. Set up the camera:

You can set up the camera by calling various methods on the Camera instance, such as:

• setPreviewSize(): sets the size of the preview frame
• setCaptureMode(): sets the capture mode (e.g. photo, video)
• setFlashMode(): sets the flash mode (e.g. on, off)
• setAutoFocusMode(): sets the autofocus mode (e.g. continuous, single-shot)

For example:

camera.setPreviewSize(640, 480);
camera.setCaptureMode(Camera.CaptureMode.PHOTO);
camera.setFlashMode(Camera.FlashMode.ON);
camera.setAutoFocusMode(Camera.AutoFocusMode.CONTINUOUS);

4. Start the camera:

Call the start() method on the Camera instance to start the camera:

camera.start();

5. Capture images or videos:

You can capture images or videos by calling the takePicture() or startRecording() methods on the Camera instance, respectively:

// Capture a photo
camera.takePicture(new Camera.CaptureCallback() {
    @Override
    public void onCaptureCompleted(Camera camera, ImageProxy image) {
        // Process the captured image
    }
});

// Start recording a video
camera.startRecording(new Camera.RecordingCallback() {
    @Override
    public void onRecordingStarted(Camera camera) {
        // Start recording
    }

    @Override
    public void onRecordingStopped(Camera camera) {
        // Stop recording
    }
});

6. Stop the camera:

Call the stop() method on the Camera instance to stop the camera:

camera.stop();

Note that the Camera class is part of the Android Camera API, which is a separate API from the traditional Android Camera API. The new camera class provides a more streamlined and easy-to-use interface for accessing the camera hardware, but it may not provide all the features and functionality of the traditional Android Camera API.
