Android - onActivityResult return NULL when I try to take picture

Question

I implemented on my app a function that I use to take pictures, usually it works but sometimes it happens, however, that the images are not saved, I have tried to debug but I cannot understand why it is not working properly.

Main function used to create the path name, to set the orientation, and to set the destination folder

public void takePhoto(CoordsDamage coordsDamage) {
    try {
        int id = dbGest.getIdDamages(coordsDamage, context);
        int nItem = new FilesUtilities().photoDamages(id, coordsDamage, context);
        int maxPhoto = Integer.parseInt(dbGest.getSetting("maxPhoto", context));
        String imageFileName = EXT_DAMAGE + coordsDamage.getWizard() + "_" + coordsDamage.getIncarico() + "_" + coordsDamage.getComponent() + "_an" + id + "_" + (nItem + 1) + ".jpg";

        if (nItem < maxPhoto) {
            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            cameraIntent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION, ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            if (cameraIntent.resolveActivity(getPackageManager()) != null) {
                File storageDir = new File(new GuiConst(context).getPdfFolderC(false));
                if (!storageDir.exists()) {
                    new FilesUtilities().createFolder(context);
                }
                File photoFile = new File(storageDir, imageFileName);
                photoInfo = coordsDamage;
                imagePath = photoFile.getPath();
                imageName = photoFile.getName();

                dbGest.insertIntoFileData(wizardID, jobID, "damages", imagePath, imageName, context);
                dbGest.updatePath(imagePath, photoInfo, context);

                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(context, "myprovider.provider", photoFile));
                startActivityForResult(cameraIntent, 1);
            }
        } else {
            Toast.makeText(ExternalDamagesNoTutorial.this, "Raggiunto limite massimo di foto per questa anomalia", Toast.LENGTH_SHORT).show();
        }
    } catch (Exception e) {
        wil.WriteFile("externalDamagesNoTutorial takePhoto - Exception: " + e.getMessage(), context);
    }
}

onActivityResult

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        try {
            if (requestCode == 1 && resultCode == RESULT_OK) {
                showDialogPhotos(photoInfo);
                Toast.makeText(this, context.getResources().getString(R.string.label_check_photo_ok), Toast.LENGTH_SHORT).show();
            } else if (requestCode == 1 && resultCode == RESULT_CANCELED) {
                dbGest.deleteFileToSendRecord(imageName, context);
                dbGest.removePath(imagePath, photoInfo, context);
                Toast.makeText(this, context.getResources().getString(R.string.label_check_photo_ko), Toast.LENGTH_SHORT).show();
            }

            loadPin = false;
        } catch (Exception e) {
            wil.WriteFile("externalDamagesNoTutorial onActivityResult - Exception: " + e.getMessage(), context);
        }
    }

photoInfo,imageName,imageName they are global variables that contain some information I need in the onActivityResult, and when the image is not saved these values take null value.

The strange thing is that resultCode still takes a RESULT_OK value even when the photo is not saved.

To summarize: typically the application works sometimes it happens that the image is not saved on the filesystem

ideas?
