edit: turns out it just takes waaay longer than the native implementation. :/
I'm trying to locate my position by using the mvvmcross location plugin.
Everything works fine as long as my device settings (Nexus 5) are set to "Energy saving", so no GPS will be used.
As soon as I set it to "High accuracy", I'll never get a GPS fix.
This happens regardless to MvxLocationAccuracy.
My current workaround is to check, whether MvxLocationAccuracy is set to "Coarse", and if so, set PowerRequirement to Power.Medium.
This will prevent Android from using GPS.
So my question is: what am I doing wrong? Why am I never getting an location, as soon as my device is using GPS?
I compared the mvvmcross plugin code to one of my native projects, which gets a high accuracy gps fix in a few seconds. Unfortunately I didn't find any errors.

In my app I need to determine user location. So I am using location manager. In my code, I first check for availability of network provider and GPS provider. I prefer networkprovider first, else I use GPS provider to get the location.
In an android device, there are three options available for location setting:
high accuracy(gps+wifi+mobile network)
battery saving(wifi+mobile network)
device only(GPS)
When within my house(WIFI on), I observe that first two options work but third one doesn't. So I ventured out of house(WIFI gone,no internet), and made observations again at a fixed point. There again, first two options worked but not the third.
Why is it so?GPS is supposed to work in open space.So I should get location for GPS too.
Then I got into a vehicle, and tested again. But now none of the options work.Even first two options stopped giving result.
Why this behaviour? I expect all three options to work outdoor. But GPS never works, and first two work only when I am stationery. Does movement plays a role here?
I am not able to comprehend the overall behaviour.
So I have an app that works flawlessly on many devices. The problem is on one specific phone with Android 6.
The location for our app only works when another app uses the GPS.
For example, starting our app, the GPS icon starts as if the GPS was active but location updates on the app do not appear or refresh. Then, we start Google Maps and only then locations on our app start getting refreshed. As soon as we close Google Maps, our locations stop being received.
I actually tested the app on another phone with Android 6 with no problems.
I think there might be some kind of issue with Google Play Services or with the new the permissions schema. Or maybe with BroadcastReceiver receiving the position updates.
Key information:
Our app es compiled for SDK 22 with Google API.
Google Play Services version on the phone with the issue is 8.4.92
The app uses this version of play services:
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.google.android.gms:play-services-location:7.+'
compile 'com.google.android.gms:play-services-maps:7.+'
compile 'com.google.android.gms:play-services-gcm:7.+'
All permissions are activated for our app on that phone.
The phone with the problem was working fine before it got updated to Android 6.0
We tested on another device with Android 6.0 and had no issues.
The phone is in a client in another continent so we don't have access to debugging or logs. No errors occur though because we would receive those on Fabric.io.
We use a Broadcast to dispatch new positions to a service and an activity so the problem might be there.
Im running out of options and tests.
Any ideas?
Thanks,
EDIT
The problem is that on that version of Android, getSpeed from Location is always 0.0, unless another app is using the location, then we get updates with the speed included.
This really sounds like a bug. Why would legacy apps not get the speed in the location? Assuming its because we use API 22.
On a side note, we use speed to filter out positions and stop updating location when the phone is standing still. Thats why we did not see location updates.
I guess we will have to calculate our own speed.
I work in QA for an company that helps market applications. Currently I have been tasked to ensure location dependent apps function if correctly (ie if im in russia the app displays the russian content and if i change to us the app updates to the us content)
I have tried numerous items to accomplish this but get no where.
What i have tried:
Proxy. Setting this up via wifi to several locations. Both the app and the device still show my current location.
Apps: I have tried all of the following apps and they all give the same result as above.
Fake Location
AutoProxy
Fake GPS
I have enabled developer mode on the devices, and have ensured that "Mock Locations" is checked.
Use case 1:
A developer whats us to test his app which is only available in england. Google Play still sees me in US
Use case 2:
A developer releases a game where the background changes based on your location if i cant force the location change I cant verify this feature works.
Im guessing the fails so far are due to the fact that the location being called in our test apps is network location not GPS?
Any help would be awesome. Even if you could just point me in a direction.
Thank you Greatly

Update:
Ok, Thanks to the answers about google play and mock locations. So with those in mind lets think about it from another perspective. If the app is not calling for mock location, Is there anyway to force a mock location override? im trying to cover all the bases here, One app for sure does not use this method, so I still need to find a way around.
depending on how they are calling for the location, I would think (remember im knew here) that using a proxy would work, however as stated above, i'm not getting anywhere there either. Did try a few free proxy's from hidemyass but even the browser wouldn't work with them.
Yes, network location does not get faked by mock location providers. I don't know why not, but it only fakes GPS. In addition, your app has to request the MOCK permission to get it. If it doesn't have this permission, setting a mock location will not actually fake anything to the app. This is for security purposes, so a malicious app can't start broadcasting the wrong location to the phone.
I am working on app. When user click on button he will get current location using GPS.
All is working fine but one problem.
Problem
There might be some location where gps will not work...like closed area...and gps can not find location...at that time it will return previously know location...Previously known location may be too older or wrong.
so at that time I want no location found instead of last location.
Is there any way to check if fix is available or not ?
I've tried to run Geofences sample and I've got little confunsed regarding to how it works.
Prior to go on, I've studied the new APIs and wached this video:
http://www.youtube.com/watch?v=Bte_GHuxUGc&list=WLRNCZT9Eq_HTG5jIEFxMpdqoXZBNalekx
So I jumped coding it. I thought that this API would manage the GPS position's captures automatically, in order to get my position.
So at this point raises my doubt. I've only got notified within a geofence, if I turnned my google map app on so my device starts capturing my location thru GPS.
So, what should I do to have "my app" forcing GPS use ?
I appreciate your help.
