如何在Android Java中编程选择第一个芯片作为默认？

import android.content.Context;
import android.hardware.camera2.CameraAccessException;
import android.hardware.camera2.CameraCharacteristics;
import android.hardware.camera2.CameraManager;
import android.util.Log;

public class CameraUtils {
    private static final String TAG = "CameraUtils";

    public static void setDefaultCamera(Context context) {
        CameraManager cameraManager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        try {
            String[] cameraIds = cameraManager.getCameraIdList();
            if (cameraIds.length > 0) {
                String defaultCameraId = cameraIds[0];
                CameraCharacteristics characteristics = cameraManager.getCameraCharacteristics(defaultCameraId);
                // 根据需要设置摄像头的其他参数
                // ...

                // 设置默认摄像头的闪光灯模式
                cameraManager.setTorchMode(defaultCameraId, true);
            }
        } catch (CameraAccessException e) {
            Log.e(TAG, "Failed to access camera", e);
        }
    }
}
