public void shareVideo(String pkgname, String appname) {
  String path = null;
  try {
    path = MediaStore.Images.Media.insertImage(getContentResolver(),
    arrImagePath.get(slidePager.getCurrentItem()), "Title", null);
  } catch (FileNotFoundException e1) {
    e1.printStackTrace();
  }
  Uri uri = Uri.parse(path);
  Intent share = new Intent(Intent.ACTION_SEND);
  share.setPackage(pkgname);
  share.putExtra(Intent.EXTRA_STREAM, uri);
  share.setType("Video/*");
  share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
  startActivity(Intent.createChooser(share, "Share image File");
}

shareVideo("com.whatsapp", "Whatsapp");
