Re: Enable gps device

I have not used the Geolocation plugin yet, but as I understand it the user must turn Location Services on before you can get the device coordinates. Geolocation data is generally considered sensitive because it can reveal a user's whereabouts, and if stored, the history of their travels. If Location Services is turned off when your app attempts to get the device's coordinates, a message should appear asking the user if it is okay to turn on Location Services.

Re: Enable gps device

I used it using phoneGap - works fine. Here is the example

1)select the Geolocation - phonegap core plugins or add the following in the config.xml
<feature name="http://api.phonegap.com/1.0/geolocation" />
<gap:plugin name="org.apache.cordova.geolocation" />

2) Create a button with the following code
// onSuccess Callback
// This method accepts a Position object, which contains the
// current GPS coordinates
//
var onSuccess = function(position) {
alert('Latitude: ' + position.coords.latitude + '\n' +
'Longitude: ' + position.coords.longitude + '\n' +
'Altitude: ' + position.coords.altitude + '\n' +
'Accuracy: ' + position.coords.accuracy + '\n' +
'Altitude Accuracy: ' + position.coords.altitudeAccuracy + '\n' +
'Heading: ' + position.coords.heading + '\n' +
'Speed: ' + position.coords.speed + '\n' +
'Timestamp: ' + position.timestamp + '\n');
};

// onError Callback receives a PositionError object
//
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
}

navigator.geolocation.getCurrentPosition(onSuccess, onError);

Copy and paste from the Geolocation documentation "WARNING: Collection and use of geolocation data raises important privacy issues. Your app's privacy policy should discuss how the app uses geolocation data, whether it is shared with any other parties, and the level of precision of the data (for example, coarse, fine, ZIP code level, etc.). Geolocation data is generally considered sensitive because it can reveal user's whereabouts and, if stored, the history of their travels. Therefore, in addition to the app's privacy policy, you should strongly consider providing a just-in-time notice before the app accesses geolocation data (if the device operating system doesn't do so already). That notice should provide the same information noted above, as well as obtaining the user's permission (e.g., by presenting choices for OK and No Thanks). For more information, please see the Privacy Guide."

Phonegap developers privacy guide - http://docs.phonegap.com/en/3.4.0/gu...rivacy%20Guide

I've no idea if it is possible to circumvent the user to turn on GPS, but am pretty sure your app would be rejected by any distributor if they were aware of it.

Thanks so much for this Information

iOS will prompt for the user's permission when an app asks for geolocation information. There is no way to get around that. Nor should there be.

When your GPS is off, does this http://i.stack.imgur.com/bDIgF.png, dialog prompts to you? Or this prompt doesn't prompt at all at Phonegaps builds? I noticed some apps have this promt. BU I can't find any doc that says this prompt is not possible in Phonegap. Also, Im building a Phonegap app intended for IOS.

Re: Enable gps device

No, not every time I use gps. It asked/asks permission when I install the application on the device- one time - and I gave all the permissions it need. [Including permission to use the camera, etc - this is on iOS iphone/iPad.]

Thanks.

I see. But I'm getting confused why other apps have this prompt http://i.stack.imgur.com/bDIgF.png on turning on location access (given that their location access is off before opening an app that uses geolplugin). Have you tried turning off your location access and open your phonegap app that uses geolocation? Does this prompt shows up?

Re: Enable gps device

Under iOS 8 Location Services does not prompt for Approval during install. The Approval Prompt is only issued when GeoLocation services are requested the first time. If an app is run but GeoLocation services are not requested during startup then Approval is not requested. If, for example, a button requests a current GeoLocation, then Approval is requested... and only the first time... only once.

Yes, permissions are displaying to me but this alert/prompt http://i.stack.imgur.com/bDIgF.png, does not appear though. Given my app is requesting for geolocation services and my Location access is off. I want the users to see this prompt so when they click the Settings button, they could be redirected to the Location Access, instead of just prompting them a customize alert that says "Please go to Settings -> Privacy -> Location -> Location Services and turn it on so tha app can access your location".

Re: Enable gps device

I think we have to break this down a bit...

A GeoLocation app only asks for permission one time... when Location Services are requested.
Permission is only requested if Location Services are turned ON.
If Location Services are OFF then the error message is : "Location services are disabled." This error is captured in your routine.
I don't think you can automatically re-direct to Location Services - at least I hope not. Is that what you're asking?
If Location Services are ON but Services have been set to Never for the app then an error is thrown, but no specific message is available.

So... although it's tough to say what's going on with your app... in my app... if Location Services are OFF there is no prompt to turn on Services... rather an error message. You say you're getting a request when Location Services are off... but I don't think so.

EDIT: I think wording is getting in the way here. You say your app is requesting for geolocation services... but that's YOU pushing out the request... not iOS... right? You've already determined that Location Services are OFF.
