title: Android Google map: Change color on map marker
body: <p>Long story short; I got at Bluetooth device measuring signal-strength of other devices in the area, and then I log the GPS positions on the Android app.</p>
  
  <p>I place the positions on a Google map in my app, but I would like the marker to change color depending on the value of signal-strength (0-255) from red to green or something like that.</p>
  
  <p>I think I need to make my own Drawable in the app or change what is in the:</p>
  
  <pre><code>Drawable drawable = this.getResources().getDrawable(R.drawable.marker);
  </code></pre>
  
  <p>But I can't find a way draw the markers in the android app.</p>
  
  <p>Any ideas?</p>
