Andriod 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 some key features of the new camera class:

1. Simplified API: The new camera class provides a simplified API that makes it easier to access the camera hardware and capture images or videos.
2. Unified API: The new camera class provides a unified API that works across multiple devices and platforms, including Android 10 and later.
3. Improved performance: The new camera class provides improved performance and reduced latency compared to the previous camera API.
4. Support for multiple cameras: The new camera class supports multiple cameras, including front and rear cameras, and allows you to switch between them easily.
5. Support for camera modes: The new camera class supports multiple camera modes, including photo, video, and preview modes.

Here is an example of how to use the new camera class in Android Studio:

import androidx.camera.core.Camera;
import androidx.camera.core.CameraSelector;
import androidx.camera.core.ImageCapture;
import androidx.camera.core.ImageCaptureException;
import androidx.camera.core.Preview;
import androidx.camera.lifecycle.ProcessCameraProvider;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import androidx.lifecycle.ViewModelProvider;

import java.io.IOException;

public class CameraActivity extends AppCompatActivity {
    private Camera camera;
    private ImageCapture imageCapture;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);

        // Request camera permissions
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION);

        // Create a camera provider
        ProcessCameraProvider cameraProvider = new ProcessCameraProvider(this);

        // Create a camera selector
        CameraSelector cameraSelector = new CameraSelector.Builder(this)
               .requireLensFacing(CameraSelector.LENS_FACING_BACK)
               .build();

        // Create a preview
        Preview preview = new Preview.Builder(this)
               .setTargetResolution(new Size(640, 480))
               .build();

        // Create an image capture
        imageCapture = new ImageCapture.Builder()
               .setTargetResolution(new Size(640, 480))
               .build();

        // Bind the camera to the preview and image capture
        cameraProvider.bindCamera(cameraSelector, preview, imageCapture);

        // Start the camera preview
        preview.start();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == REQUEST_CAMERA_PERMISSION && grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted, start the camera preview
            startCameraPreview();
        }
    }

    private void startCameraPreview() {
        // Start the camera preview
        cameraProvider.bindCamera(cameraSelector, preview, imageCapture);
    }
}

In this example, we create a CameraActivity that uses the new camera class to access the camera hardware and capture images or videos. We request camera permissions, create a camera provider, create a camera selector, create a preview, create an image capture, and bind the camera to the preview and image capture. We then start the camera preview by calling the startCameraPreview() method.

Note that this is just a basic example, and you will need to modify it to fit your specific use case. You may also need to add additional error handling and other features depending on your requirements.
