Application crashes every time camera open

I've written an application which should take picture and record video and then show it on the screen. When trying it on phone the camera won't work but works in emulator.
When executing the app this is what exactly happens:
Every time I clicked on the button to open the camera, the app stopped and the error it display is Appname has stopped, Open app again
When I clicked on Open app again it return to normal state
I have granted the camera permission in my program
below is my code:

I have tried following this tutorial but it doesn't work in my case.The error occurs when I try mGmap.snapshot(snapshotReadyCallback);. I have initialized the map in the lines above and gotten the location using FusedLocationProviderClient api.
Can anyone help me understand why it's throwing this error? Thanks

This is my camera fragment code. When i give permission at runtime the surfaceview does not show camera. It show camera at onResume() or on any Button click in that fragment.How to solve this issue. How to set When i click on Allow button in permission it shows camera in surface view automatically.

In onCreate set visibilty of surfaceView as INVISIBLE.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
if (checkCameraHardware(this) == false) {
showDialogForExit();
}
surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
surfaceView.setVisibility(View.INVISIBLE);
infoTextview = (TextView) findViewById(R.id.info_text);
askForPermissions();
}
Then after attaching cameraSource to surfaceView,set visibilty of surfaceView to VISIBLE again.
surfaceView.setVisibility(View.VISIBLE);

Write this code in your activity onCreate() Method
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
runTimePermission = new RunTimePermission(this);
runTimePermission.requestPermission(new String[]{Manifest.permission.CAMERA,
Manifest.permission.RECORD_AUDIO,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
}, new RunTimePermission.RunTimePermissionListener() {
#Override
public void permissionGranted() {
// First we need to check availability of play services
initControls();
identifyOrientationEvents();
//create a folder to get image
folder = new File(Environment.getExternalStorageDirectory() + "/Media");
if (!folder.exists()) {
folder.mkdirs();
}
//capture image on callback
captureImageCallback();
//
if (camera != null) {
Camera.CameraInfo info = new Camera.CameraInfo();
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
imgFlashOnOff.setVisibility(View.GONE);
}
}
}
#Override
public void permissionDenied() {
}
});
then write this code out of onCreate()
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (runTimePermission != null) {
runTimePermission.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

Sorry for late answer, but maybe it will be useful to someone. Just call start camera method in your onRequestPermissionsResult like this:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
Utils.log(TAG, "onRequestPermissionsResult call");
if (requestCode == REQUEST_CAMERA_PERMISSION) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Utils.log(TAG, "Permission granted - show camera");
if (ActivityCompat.checkSelfPermission(requireContext(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
try {
cameraSource.start(surfaceView.getHolder());
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
The default way to show camera might look like this:
surfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {
#Override
public void surfaceCreated(SurfaceHolder holder) {
try {
if (ActivityCompat.checkSelfPermission(requireContext(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
cameraSource.start(surfaceView.getHolder());
Utils.log(TAG, "Check permission: granted - start camera");
} else {
Utils.log(TAG, "Check permission: restricted - request");
requestPermissions(new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION);
}
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
cameraSource.stop();
}
});

It worked for me:
before get permission or show any dialogs set surface visibility to GONE
surfaceView.setVisibility(View.GONE);
then after get permission or dismiss dialogs set surface visibility to VISIBLE
surfaceView.setVisibility(View.VISIBLE);

you have to receive your permission details here
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_CAMERA_PERMISSION:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Here call or Open your camera;
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}

Is disappearing after going to another activity but showing uploading to server Glide and volley

I have created two functionality for photo uploading in my app. The first one is for capture image and the second one is for pick image from gallery. Now I have a photo API as URL. By using this API I have to upload the image at first to server and from server it will be available throught the app. Now I can successfully uploaded the picture in server and in the server side shows the picture. But in the imageview of app does not show that image. Whenever I go to another activity and then come back to image activity the imageview is empty. I have used shared preference to keep the image at image view, but that does not work.

Please don't use
image.setImageURI(uri);
image.invalidate();
Please use this code below instead of that :
try {

image.setImageBitmap(bitmap);
} catch (IOException e) {
