要创建一个Android相机应用程序，可以使用GLSurfaceView来显示相机预览。以下是一个包含代码示例的基本解决方案：

1. 在Android Studio中创建一个新的Android项目。
2. 在build.gradle文件中添加以下依赖项：

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9'
implementation 'androidx.camera:camera-core:1.0.0-beta08'
implementation 'androidx.camera:camera-camera2:1.0.0-beta08'
implementation 'androidx.camera:camera-lifecycle:1.0.0-beta08'
implementation 'androidx.camera:camera-view:1.0.0-alpha28'
implementation 'androidx.camera:camera-extensions:1.0.0-alpha28'
implementation 'androidx.camera:camera-view:1.0.0-alpha28'

3. 在layout文件夹中创建一个新的布局文件，命名为activity_main.xml，并添加以下代码：

4. 在MainActivity.kt文件中添加以下代码：

import android.Manifest
import android.content.pm.PackageManager
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import android.widget.Toast
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 kotlinx.android.synthetic.main.activity_main.*
import java.io.File
import java.text.SimpleDateFormat
import java.util.*

class MainActivity : AppCompatActivity() {

    private lateinit var imageCapture: ImageCapture
    private lateinit var outputDirectory: File

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // Request camera permissions
        if (allPermissionsGranted()) {
            startCamera()
        } else {
            ActivityCompat.requestPermissions(
                this,
                REQUIRED_PERMISSIONS,
                REQUEST_CODE_PERMISSIONS
            )
        }

        // Setup the directory where the captured images will be saved
        outputDirectory = getOutputDirectory()

        // Set up the listener for take photo button
        btnTakePhoto.setOnClickListener { takePhoto() }
    }

    private fun startCamera() {
        val cameraProviderFuture = ProcessCameraProvider.getInstance(this)

        cameraProviderFuture.addListener({
            val cameraProvider: ProcessCameraProvider = cameraProviderFuture.get()

            val preview = Preview.Builder()
                .build()
                .also {
                    it.setSurfaceProvider(previewView.surfaceProvider)
                }

            imageCapture = ImageCapture.Builder()
                .build()

            // Select back camera as the default
            val cameraSelector = CameraSelector.DEFAULT_BACK_CAMERA

            try {
                cameraProvider.unbindAll()

                // Bind the camera to the lifecycle
                cameraProvider.bindToLifecycle(
                    this,
                    cameraSelector,
                    preview,
                    imageCapture
                )

            } catch (exc: Exception) {
                Log.e(TAG, "Use case binding failed", exc)
            }

        }, ContextCompat.getMainExecutor(this))
    }

    private fun takePhoto() {
        val imageCapture = imageCapture ?: return

        // Create a timestamped output file to hold the captured image
        val photoFile = File(
            outputDirectory,
            SimpleDateFormat(
                FILENAME_FORMAT, Locale.US
            ).format(System.currentTimeMillis()) + ".jpg")

        // Create the output options object which contains the file + metadata
        val outputOptions = ImageCapture.OutputFileOptions.Builder(photoFile).build()

        // Set up image capture listener, which is triggered after photo has
        // been taken
        imageCapture.takePicture(
            outputOptions, ContextCompat.getMainExecutor(this), object : ImageCapture.OnImageSavedCallback {
                override fun onError(exc: ImageCaptureException) {
                    Log.e(TAG, "Photo capture failed: ${exc.message}", exc)
