How to know gps fix is available or not? - android

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 ?

Mock coordinates Android Marshmallow

In my app I am using Android Location Manager API and I have a requirement of identifying whether the location coordinates are from normal Location Manager or if they are from Fake(Mock) Location provider. I used location.isFromMockProvider(). Once I turn on the fake location providing app, isFromMockProvider() method returns me true. And after that it does not matter if I turn, fake location providing app, on or off isFromMockProvider() method always returns true.
I found that once FakeGPS app, once triggered, overrides the location manager coordinates and once I stop the FakeGPS app, the Location Manager does not start collecting correct coordinates.
Is there something I am missing.
Disappointed with no response but I am glad that I got it working :)
Posting the resolution as it might help someone else.
Once the FakeGPS app starts mocking location, it stops my app's Location manager.
Now even if I stop the FakeGPS app mocking service, the location manager of my app won't trigger back.
I have to detect the event and restart the location manager of my app, after removing any test provider and clearing test locations.
just resetting and removing test location should help
String t = LocationManager.GPS_PROVIDER;
locationManager.clearTestProviderEnabled(t);
locationManager.clearTestProviderLocation(t);
locationManager.clearTestProviderStatus(t);
locationManager.removeTestProvider(t);

Never getting an Location (MvvmCross Location Plugin, Android)

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.

How to get user's location?

I want to get user's location in my app. So, I read documentations and know how to get it work. But, if user haven't set "Alloy apps to use internet/GPS to get location" in preferences, my app crashes.
The only way I found is to show dialog that location settings are not enabled and to go programmaticaly to location preferences.
But is there another way to solve this? I saw many apps (like yandex.maps) that do not request this settings being enabled.
well, your app should not install if the user doesn't agree to the terms of use, and allow the permissions requested.
still you should check to see that there's a way to look the information up when you want it.
in your code, before the actual test for user's location, you should probably call a function that checks for all the location manager listings, and return false if there's no way to determine this.
if the function returns false, you should prompt the user and do nothing. else, you should do what it is you're trying to do.
