   share.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                int permissionCheck = ContextCompat.checkSelfPermission(SingleProduct.this,
                        Manifest.permission.READ_EXTERNAL_STORAGE);

                if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
                    Log.e("MainActivity ", "P granted");

                    bmpUri = getLocalBitmapUri(imageView);

                } else {
                    ActivityCompat.requestPermissions(SingleProduct.this,
                            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
                }
            } else {
                Log.e("MainActivity", "Lower Than MarshMallow");
                bmpUri = getLocalBitmapUri(imageView);
            }

            if (bmpUri != null) {
                // Construct a ShareIntent with link to image
                Intent shareIntent = new Intent();
                shareIntent.setAction(Intent.ACTION_SEND);
                shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
                shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                shareIntent.setType("image/*");
                startActivity(Intent.createChooser(shareIntent, "Share Image"));
            } else {
                Toast.makeText(SingleProduct.this, "Sharing Failed !!", Toast.LENGTH_SHORT).show();
            }
        }
    });

 public Uri getLocalBitmapUri(ImageView imageView) {
    Drawable drawable = imageView.getDrawable();
    Bitmap bmp = null;
    if (drawable instanceof BitmapDrawable) {
        bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    } else {
        return null;
    }
    Uri bmpUri = null;
    try {
        File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();

       bmpUri = Uri.fromFile(file);


    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}
