    You're probably running a Samsung device. I believe this is a bug that occurs in these devices. You have to get the URI otherwise. Do this:

    /**
      * (This is a variable instance) Contains the path and file name where you want to save the image.
      * Mainly used to start Intent.Action_View with this URI. (GalleryApp)
      */
    private Uri uriImage= null;
    
    public void onClickCamera(View v){
        // Cria uma intent para capturar uma imagem e retorna o controle para quem o chamou (NAO PRECISA DECLARAR PERMISSAO NO MANIFESTO PARA ACESSAR A CAMERA POIS O FAZEMOS VIA INTENT).
        // Creates an intent to capture an image and returns control to the caller
        Intent intent = new Intent( MediaStore.ACTION_IMAGE_CAPTURE );
        // Cria um arquivo para salvar a imagem.
        // Creates an file to save the image.
        uriImage = ProcessaImagens.getOutputMediaFileUri( ProcessaImagens.MEDIA_TYPE_IMAGE, getActivity().getApplicationContext() );
        // Intent to pass a URI object containing the path and file name where you want to save the image. We'll get through the data parameter of the method onActivityResult().
        intent.putExtra( MediaStore.EXTRA_OUTPUT, uriImagem );
        // Starts the intent to image capture and waits the result.
        startActivityForResult( intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE );
    }
    

    The ProcessaImagens class is a class that I coded and I'm sharing with everyone. Can use this class to facilitate. It has a very good method to compress the image if you want to save images in the database. In its onActivityResult() method do this:

    @Override
    public void onActivityResult( int requestCode, int resultCode, Intent data ) {
        // If finished activity on startForActivityResult.
        if ( resultCode == Activity.RESULT_OK ) {
            if ( requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE ) {
                String imagePath = uriImage.getPath();
                // I will compress the imagem. Read the javadoc from method and you'll see which it returns both bitmap and array bytes.
                List imageCompact = ProcessaImagens.compactarImagem( uriImagem.getPath() );
                Bitmap imageBitmap = (Bitmap) imageCompact.get( 0 );
                byte[] imageBytes = (byte[]) imageCompact.get( 1 );
    
            }
        }
        // If canceled activity on startForActivityResult.
        else if ( resultCode == Activity.RESULT_CANCELED ) {
            if ( requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE ) {
                // User canceled the image capture.
                Log.d( getTag(), "Image capture canceled!" );
            }
        }
        // If an error occurred in the activity on startForActivityResult.
        else {
            // Failed the image capture, alert the user.
            Toast.makeText( getActivity().getApplicationContext(), "FAILED! The image capture failed!", Toast.LENGTH_LONG ).show();
            Log.e( getTag(), "FAILED! The image capture failed!" );
        }
    }
    
    
    

    Note that I used getActivity().getApplicationContext() because I'm getting the context from a Fragment and not from Activity. I believe with this method you can have what you want. Just make little changes how form to get context.
