我正在开发一个应用程序，其中我使用play-services-vision版本17.0.2扫描qrcode。.我正在运行android oreo 8.1.0的Galaxy S5上对其进行测试。一旦我的代码到达CameraSource.start（holder）行，应用程序将关闭，而不会发出任何警告。谁能帮我吗？
ps .：我没有在其他设备上尝试过，仅在模拟器上尝试过，但是相机在那儿无法正常工作。
ps2 .：所有权限都在运行时给出，但也在清单中
给出<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.hardware.camera" />
<uses-permission android:name="android.hardware.camera.autofocus" />
代码
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
_surfacce = (SurfaceView)findViewById(R.id.surfaceView);
_detector = new BarcodeDetector.Builder(getApplicationContext())
.setBarcodeFormats(Barcode.QR_CODE)

_camera=new CameraSource.Builder(getApplicationContext(),_detector)
.setRequestedFps(15.0f)
.setAutoFocusEnabled(true)
.setRequestedPreviewSize(size.x,size.y)
.setFacing(CameraSource.CAMERA_FACING_BACK)
.build();
_surfacce.getHolder().addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceCreated(SurfaceHolder holder) {
if(ContextCompat.checkSelfPermission(getApplicationContext(),Manifest.permission.CAMERA)!= PackageManager.PERMISSION_GRANTED){
getParent().finish();
return;
}
try {
_camera.start(_surfacce.getHolder()); //<<<< CRASHES HERE
} catch (Exception e) {
Log.e("CAMERA SOURCE", e.getMessage());
