        // Get access to the URI for the bitmap
        Uri bmpUri = getLocalBitmapUri(descpic);
        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);

Do this to save image. Replace your method with this

public Uri getLocalBitmapUri(ImageView imageView) {
    imageview.buildDrawingCache();
    Bitmap bm = imageview.getDrawingCache();

    OutputStream fOut = null;
    Uri outputFileUri;
    try {
        File root = new File(Environment.getExternalStorageDirectory()
            + File.separator + "folder_name" + File.separator);
        root.mkdirs();
        File imageFile = new File(root, "myPicName.jpg");
        outputFileUri = Uri.fromFile(imageFile);
        fOut = new FileOutputStream(imageFile);
    } catch (Exception e) {
        e.printStackTrace();
    }

    try {
        bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
        fOut.flush();
        fOut.close();
        return outputFileUri;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}
