    copied!<p>I just got bit by this too.</p> <p>It turns out there's a bug in Sencha: in <a href="http://docs.sencha.com/touch/2-0/source/Geolocation.html#Ext-util-Geolocation" rel="nofollow">Ext.util.Geolocation.parseOption</a> they name the parameter <code>allowHighAccuracy</code> but <a href="http://dev.w3.org/geo/api/spec-source.html" rel="nofollow">the w3c specs</a> name it <code>enableHighAccuracy</code>. I added the following code to my application init to fix that:</p> <pre><code>var parseOptions = function() { var timeout = this.getTimeout(), ret = { maximumAge: this.getMaximumAge(), // Originally spells *allowHighAccurancy* enableHighAccuracy: this.getAllowHighAccuracy() }; //Google doesn't like Infinity if (timeout !== Infinity) { ret.timeout = timeout; } return ret; }; Ext.util.Geolocation.override('parseOptions', parseOptions); </code></pre> <p>For the record: the bug <a href="http://www.sencha.com/forum/showthread.php?130292-OPEN-TOUCH-137-enableHighAccuracy-allowHighAccuracy-in-GeoLocation" rel="nofollow">has been reported over a year ago</a>, and <code>the fix was applied for TOUCH-2804 in a recent build</code>. I don't know what that means, but sure enough the bug is still in 2.0</p> <p>EDIT: using the approach mentioned above doesn't work well either. The GPS icon would turn on and off as Exts calls getCurrentPosition repeatedly using a setInterval. The reason for doing this is that <code>The native watchPosition method is currently broken in iOS5</code>. In my Android targeted application I ended up ditching Ext:util.Geolocation and directely used navigator.geolocation.watchPosition. After that it worked like a charm.</p>
