Android Emulator having issues with Geolocation

Question

I have been using Android and the 2.2 emulator for a bit now and just started running into an issue. My geolocation is not being set in the Emulator. At first I thought it was an issue with PhoneGap 0.92 but after reverting to .91 and opening an older project the same holds true. In DDMS my coordinates are set and I 'send' them. I also telnet and issue the geo fix command and I get a OK response. It seems all is well but for some reason the emulator still has no clue.

I found some older posts re: setting the time zone. I did that. Still no luck. I even use the browser and go to html5demos.com/geo to see if it can find me and it does not.

This used to work, not sure what happened since then. I updated my version of Java 1.6.0.22. Android SDK is 2.2, API 8, revision 2.

Any tips or tricks would be appreciated. I am stuck at this point.

My Phonegap/JS call:

var getLocation = function() {
  var suc = function(p){
        alert(p.coords.latitude + " " + p.coords.longitude);
  };
 var fail = function(error){  
    alert('code: '    + error.code    + '\n' +
            'message: ' + error.message + '\n');
  };
  navigator.geolocation.getCurrentPosition(suc,fail);
}

The 'fail' keeps happening. Error code 2. The last location provider was disabled.

--UPDATE Still having the same issue. I found an older mapping application I used back in the summer, it was 2.1. So I recompiled and ran that on a 2.1 emulator and that is also not working. The funny thing is in eclipse when i am in DDMS and send coordinates to 2.1 I 'see' a confirmation that it has been sent in the emulator but with 2.2 I do not.

The big difference is I am behind a proxy now (new job) where before I was not. I guess I could try at home...not sure if that matters.

Answer 1

You have to put enableHighAccuracy into getCurrentPosition, for example:

navigator.geolocation.getCurrentPosition(onSuccess, onError, { maximumAge: 3000, timeout: 5000, enableHighAccuracy: true });

Next, you have to telnet into the emulator, and geo fix the location(longitude, latitude) you want:

kelvin@locahost:~$ telnet localhost 5554
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
Android Console: type 'help' for a list of commands
OK
geo fix 101.689453 3.074695
OK
quit
Connection closed by foreign host.

Then run your PhoneGap app.

Answer 2

The only way I have found to make this work is to telnet to the emulator and issue a "geo fix longitude latitude" after I have triggered the code which I am testing. Something like this emulates GPS coordinates for Trondheim, Norway (the port of the emulator is usually 5554, but this can vary with your settings):

kristian@bergman:~$ telnet localhost 5554
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
Android Console: type 'help' for a list of commands
OK
geo fix 10.40 63.40
OK
quit
Connection closed by foreign host.

Answer 3

I had the same problem. The solution is at the end of http://docs.phonegap.com/phonegap_geolocation_geolocation.md.html#Geolocation (scroll down):

"Android Quirks

The Android 2.x simulators will not return a geolocation result unless the enableHighAccuracy option is set to true.

{ enableHighAccuracy: true }"

So you have to set enableHighAccuracy at your navigator.geolocation.getCurrentPosition and your navigator.geolocation.watchPosition calls.
