【中文标题】EGL 错误：0x3003，相机设备遇到严重错误（Camera2 Api）【英文标题】：EGL error: 0x3003, The camera device has encountered a serious error (Camera2 Api) 【发布时间】：2019-01-05 00:47:39 【问题描述】：我正在编写一个应用程序控制闪光灯相机手机，我可以控制闪光灯的开或关。但它只工作了几次，然后就崩溃了。
我不明白它崩溃的原因。我很累。
这是我的代码：
class FlashActivity : AppCompatActivity()
private val PERMISSIONS_REQUEST_CAMERA = 1
private var sX = 0f
private var sY = 0f
private lateinit var button: Button
private lateinit var camManager: CameraManager
private lateinit var camDevice: CameraDevice
private lateinit var request: CaptureRequest.Builder
private lateinit var camSession: CameraCaptureSession
override fun onCreate(savedInstanceState: Bundle?)
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_flash)
getScreen()
setUI()
init()
private fun openCamera()
if(ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.CAMERA), PERMISSIONS_REQUEST_CAMERA)
else
if(getListCamera().lastIndex > 0)
camManager.openCamera(getListCamera()[0], OpenCallback(), null)
else
Toast.makeText(this, "this device is not support", Toast.LENGTH_SHORT).show()
private fun init()
camManager = this.getSystemService(android.content.Context.CAMERA_SERVICE) as CameraManager
openCamera()
private fun getListCamera(): List<String>
var list = listOf<String>()
for (i in camManager.cameraIdList)
list += i
return list
private fun event()
var i = 0
button.setOnClickListener
if(i%2 == 0)
button.text = "On"
request.set(CaptureRequest.FLASH_MODE, CaptureRequest.FLASH_MODE_TORCH)
else
button.text = "Off"
request.set(CaptureRequest.FLASH_MODE, CaptureRequest.FLASH_MODE_OFF)
camSession.setRepeatingRequest(request.build(), null, null)
i++
private fun setUI()
button = Button(this)
button.isActivated = false
button.text = "Off"
button.measure(0, 0)
rl_flash_activity.addView(button)
button.x = sX*50 - button.measuredWidth/2
button.y = sY*50
private fun getScreen()
val manager = windowManager.defaultDisplay
val point = Point()
manager.getSize(point)
sX = point.x/100f
sY = point.y/100f
inner class OpenCallback: CameraDevice.StateCallback()
override fun onOpened(camera: CameraDevice)
Log.d("camera", "opened")
camDevice = camera
request = camDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE)
val texture = SurfaceTexture(1)
texture.setDefaultBufferSize(1, 1)
request.addTarget(Surface(texture))
val outputSurface = ArrayList<Surface>(1)
outputSurface.add(Surface(texture))
try
camDevice.createCaptureSession(outputSurface, CameraCaptureSessionCallBack(), null)
catch (e: Exception)
event()
override fun onDisconnected(camera: CameraDevice)
override fun onError(camera: CameraDevice, error: Int)
Log.d("camera", "err")
open inner class CameraCaptureSessionCallBack: CameraCaptureSession.StateCallback()
override fun onConfigureFailed(session: CameraCaptureSession)
Log.d("CaptureSession", "false")
override fun onConfigured(session: CameraCaptureSession)
camSession = session
camSession.setRepeatingRequest(request.build(), null, null)
override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray)
if (requestCode == PERMISSIONS_REQUEST_CAMERA)
// Request for camera permission.
if (grantResults.size == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
// Permission has been granted. Start camera preview Activity.
openCamera()
else
// Permission request was denied.
Toast.makeText(this, "permission is not granded", Toast.LENGTH_SHORT).show()

【问题讨论】：
【参考方案1】：解决了。我将val texture = SurfaceTexture(1) 移至onCreate()，它工作正常
