Displaying images

[Desbrina]

I'm getting reports of security exceptions when trying to display images. I've found that I need to use provider to display them without the error.

At the moment I add the images using

 @Override
    public boolean onMenuItemClick(MenuItem item) {
        String clicked = item.getTitle().toString();

        if(clicked.equals("Take Photo")) {
            if (ContextCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                if (intent.resolveActivity(getContext().getPackageManager()) != null) {
                    File file = null;
                    try {
                        file = createImageFile();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    photoUri = null;
                    if (file != null) {
                        photoUri = Uri.fromFile(file);
                        intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
                        startActivityForResult(intent, 0);
                    }
                }
            } else {
                Toast.makeText(getContext(),"No camera permissions.",Toast.LENGTH_SHORT).show();
            }
        } else {
            Intent pickPhoto = new Intent(Intent.ACTION_OPEN_DOCUMENT, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            pickPhoto.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, false);
            startActivityForResult(pickPhoto , 1);
        }
        return true;
    }

    public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
        super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
        switch(requestCode) {
            case 0:
                if(resultCode == RESULT_OK){
                    imageView.setImageURI(photoUri);
                    final int takeFlags = imageReturnedIntent.getFlags() & (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
                    getContext().getContentResolver().takePersistableUriPermission(photoUri, takeFlags);
                }

                break;
            case 1:
                if(resultCode == RESULT_OK){
                    Uri selectedImage = imageReturnedIntent.getData();
                    this.imageView.setImageURI(selectedImage);
                    photoUri = selectedImage;
                    final int takeFlags = imageReturnedIntent.getFlags() & (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
                    getContext().getContentResolver().takePersistableUriPermission(photoUri, takeFlags);
                }
                break;
        }
    }

And they are displayed with

    @Override
    public void onBindViewHolder(ProjectListViewHolder holder, int position) {
        JoinProjectPicture projectPicture = mProjects.get(position);
        Project current = projectPicture.getProject();
        Picture picture = projectPicture.getPicture();

        holder.projectName.setText(current.getProjectName() + "(" + current.getWidth() + "x" + current.getHeight() + ")");
        holder.projectStatusTV.setText(current.getStatus());

        if(picture != null) {
            String pictureName = picture.getPictureName();
            Uri uriParsed = Uri.parse(pictureName);

            holder.projectStatusTV.setText("" + uriParsed);

            if (ContextCompat.checkSelfPermission(act, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                holder.imageV.setImageURI(uriParsed);
            }
        }
    }

Can anyone point me in the right direction. I need this to apply to new saved images and the existing saved ones.
