title: Decoding polylines
body: <p>To this topic I have found a very good and helpful entry:</p>
  
  <p><a href="https://stackoverflow.com/questions/6708408/map-view-draw-directions-using-google-directions-api-decoding-polylines/8871552#8871552">Map View draw directions using google Directions API - decoding polylines</a></p>
  
  <p>But I have a question to the answer of Kenny.
  He has written a function called decodeZoomLevels(String encodedZoomLevels)</p>
  
  <p>and what paramenter is the encodedZoomLevels?</p>
  
  <p>As my direction API response I get a polyline entry like this:</p>
  
  <pre><code>     .
       .
       .        
        "polyline" : {
                      "points" : "grheHevjqAo@i@WMm@]a@QUGoAKqAG{@Ea@Ge@E]Im@Wa@Ou@Uy@MEI]OAICGEECAGAG@A@A?CBABAFc@HOJeB?}FNiBHaENw@Be@Bc@Ee@Gq@Wo@[w@i@[c@c@q@mAgC_@u@e@{@aA{Ai@k@u@w@c@g@w@gAiAqBMUEIaCsEmBuDqBqEkAyB{@gASWs@s@aBcBc@o@g@{@_@w@c@m@USWOg@O_@E}AGS?UA[COCe@O}@s@q@kA[aAUuASmAS}@So@IOQYc@s@w@u@u@Y"
                   },
       . 
       .
       .
  </code></pre>
  
  <p>As you can see the polyline entry has only another entry called "points", but wehere is the entry "zoomlevel" as Kenny is describing?</p>
  
  <p>Hope you can help.</p>
