Android Share Intent for a Bitmap - is it possible not to save it prior sharing?

Question

I try to export a bitmap from my app using share intent without saving a file for a temporal location. All the examples I found are two-step 1) save to SD Card and create U

Answer 1

If anyone still looking for easy and short solution without any storage permission (Supports nougat 7.0 as well). Here it is.

Add this in Manifest

Now create provider_paths.xml

Finally Add this method to your activity/fragment (rootView is the view you want share)

 private void ShareIt(View rootView){
        if (rootView != null && context != null && !context.isFinishing()) {
            rootView.setDrawingCacheEnabled(true);
            Bitmap bitmap = Bitmap.createBitmap(rootView.getDrawingCache());
            if (bitmap != null ) {
                 //Save the image inside the APPLICTION folder
                File mediaStorageDir = new File(AppContext.getInstance().getExternalCacheDir() + "Image.png");

                try {
                    FileOutputStream outputStream = new FileOutputStream(String.valueOf(mediaStorageDir));
                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
                    outputStream.close();

                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }

                if (ObjectUtils.isNotNull(mediaStorageDir)) {

                    Uri imageUri = FileProvider.getUriForFile(getActivity(), getActivity().getApplicationContext().getPackageName() + ".provider", mediaStorageDir);

                    if (ObjectUtils.isNotNull(imageUri)) {
                        Intent waIntent = new Intent(Intent.ACTION_SEND);
                        waIntent.setType("image/*");
                        waIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
                        startActivity(Intent.createChooser(waIntent, "Share with"));
                    }
                }
            }
        }
    }

Update:

As @Kathir mentioned in comments,

DrawingCache is deprecated from API 28+. Use below code to use Canvas instead.

 Bitmap bitmap = Bitmap.createBitmap(rootView.getWidth(), rootView.getHeight(), quality);
    Canvas canvas = new Canvas(bitmap);

    Drawable backgroundDrawable = view.getBackground();
    if (backgroundDrawable != null) {
        backgroundDrawable.draw(canvas);
    } else {
        canvas.drawColor(Color.WHITE);
    }
    view.draw(canvas);

    return bitmap;
