Open image viewer from url stored in data bases android

Question

I am working on android application in which i am storing image in data bases, and on displaying time my url is like : http://files.parsetfss.com/ee6c904a-c395-4a92-bb80-9fe687901411/tfss-4a6bdb3c-5818-4057-964f-99bcf23f3d35-1425711426766.jpg I have seen codes to open image viewer by using File name like the following code:

    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.fromFile(file));
           intent.setDataAndType(Uri.fromFile(file),"image/png");
           mActivity.startActivity(intent);

But the problem is that my url is not in file format, at the time of image displaying i am using the following code:

 String url "";
    url = data.getText(); // Coming from the data base as a link
    Picasso.with(view.getContext()).load(url).into(mHolder.mImgReceived);

I need to open image viewer from that link which is coming from databases http://files.parsetfss.com/ee6c904a-c395-4a92-bb80-9fe687901411/tfss-4a6bdb3c-5818-4057-964f-99bcf23f3d35-1425711426766.jpg . At the time of displaying it with picasso it is showing me the picture, i need to open the same image with image viewer. Please help me out here.

try this,

String url "";
    url = data.getText(); // Coming from the data base as a link

     Uri myUri = Uri.parse(url);
        Intent intent = new Intent(android.content.Intent.ACTION_SEND);
                    intent.setAction(Intent.ACTION_VIEW);
                    intent.setDataAndType(myUri , "image/png");
                    startActivity(intent);

use this code snippet

            Intent intent = new Intent(android.content.Intent.ACTION_SEND);
            intent.setAction(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse("file://" + a), "image/*");
            startActivity(intent);

            //a is path to image
            a = "/storage/primery/lagacy/kids/123.png"
