title: Use Google Maps JavaScript API in a WebView or MapView directly？Advantages and disadvantages？
body: <p>It seems that developing a map app in a Mapview on android is more traditional.<br>
  But I feel the other way also sounds very irresistible.  </p>
  
  <p>Since I was developing webs before, I feel more familiar to control Google Map API by JavaScript. And thanks to the strong feature of Android about <a href="http://code.google.com/intl/en/apis/maps/articles/android_v3.html" rel="nofollow">JavaScript interacting with Action</a>, It seems the only reason to hesitate is the performance? Which I have not tested yet.</p>
  
  <p>When considering cross-platform， JavaScript has the advantage again, I can modify my app to fit other platform easily, there are even open-source projects like the <a href="http://www.phonegap.com/" rel="nofollow">PhoneGap</a> to help me do this.  </p>
  
  <p>Is any one has done this before can tell me about what I should be care for?<br>
  And I don't know if the JavaScript API key works on local webpages?  </p>
  
  <p>Very welcome to discus Advantages and disadvantages of the two ways and share your opinions!</p>
