title: How to launch map intent with a marker/overlay item at given latitude and longitude?
body: <p>I have a latitude and longitude and I want to open google maps centred at that point. So i use the following code for it:</p>
  
  <pre><code>Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
      Uri.parse("geo:"+lat +","+lng));
  startActivity(intent);
  </code></pre>
  
  <p>However, this does not place a marker on the center. I want to place some kind of marker at the the point I start with (and optionally some kind of name for it). Any idea how this can be achieved?</p>
