  <p>I know how to use Picasso for the image, but I don't know how to add that "marker icon" on the bottom and the borders.</p>
  
  <pre><code>Picasso.with(mContext)
              .load(url)
              .resize(250, 250)
              .centerInside()
              .into(new Target() {
                  @Override
                  public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                      Marker driver_marker = mMap.addMarker(new MarkerOptions()
                              .position(new LatLng(Double.parseDouble(lat), Double.parseDouble(lng)))
                              .icon(BitmapDescriptorFactory.fromBitmap(bitmap))
                              .title(name)
                              .snippet(address)
                      );
  
  
                      @Override
                      public void onBitmapFailed (Drawable errorDrawable){
                      }
  
                      @Override
                      public void onPrepareLoad (Drawable placeHolderDrawable){
                      }
                  });
              }
  </code></pre>
  
  <p>I added this inside the onBitmapLoaded:</p>
  
  <pre><code>Paint paint = new Paint();
      paint.setColor(Color.YELLOW);
      paint.setStrokeWidth(10);
      paint.setShadowLayer(5, 0, 1, Color.RED);
  
      Canvas canvas = new Canvas(bitmap);
      canvas.drawLine(0, 0, canvas.getWidth(), 0, paint);
      canvas.drawLine(0, 0, 0, canvas.getHeight(), paint);
      canvas.drawLine(0, canvas.getHeight(), canvas.getWidth(), canvas.getHeight(), paint);
      canvas.drawLine(canvas.getWidth(), 0, canvas.getWidth(), canvas.getHeight(), paint);
  </code></pre>
  
  <p>And that seems to added the borders, but how do I add that inverted pyramid with the Canvas? Thanks, after that, I'm pretty much done! :D</p>
