How To Prevent Double Prompt For Geolocation In Phonegap App?

I created a PhoneGap app for iPhone that uses geolocation via JavaScript inside webview. When I run the app the first time, it'll prompt me to allow geolocation for this app. When

Solution 1:

I found the cause for the issue.

The call to navigator.geolocation.getCurrentPosition(onsuccess, onerror) happens before Phonegap was fully loaded.

This means that the geolocation call of webview (and not a native call via PhoneGap) is being triggered which will again ask for permission (which does make sense). Compare it to the normal Safari browser on your Smartphone. It'll ask for geolocation permission for every new website. It's the same when loading index.html via PhoneGap on application startup.

However, the solution is to wait for the deviceready event which gets fired when PhoneGap has fully loaded:

document.addEventListener("deviceready", function(){
     navigator.geolocation.getCurrentPosition(onsuccess, onerror, params);
}, false);

This will make the PhoneGap API available which overwrites the default HTML5 gelocation call of the browser and get the device's geo location via a native call (which you already accepted in the first prompt).

This will work because PhoneGap's API calls are identical to the standard W3C call for HTML5: http://docs.phonegap.com/en/2.2.0/cordova_geolocation_geolocation.md.html#Geolocation

Solution 2:

Have a look at this: Location permission alert on iPhone with PhoneGap

The second one seems to be the Webkit alert. In order to prevent this, you seem to have to simply move all your js files to the root directory. Tell me, if it works since I'll have to address the same issue soon.

Finally fixed the issue.

IN the index.html just move your cordova.js up <script src="cordova.js"></script>

as the first js file to be included (especially make sure it is above maps include js). This will make sure that the prompt shows only once

I solved this problem by moving the

<scriptsrc="cordova.js"></script>

as the last script to be included
