I found that
Android’s Location Manager API
Google Play Services Location APIs
Google Maps Geolocation API
can get current location, what is the difference between them?
Especially Google Maps Geolocation API is not free, why should one use that instead of free ones?
Maybe Android's location Manager and Google play service location is only available to Android device, while Google Maps Geolocation works both on Android and iOS?
I don't have a lot of experience with what you're talking about, but I did some research about differences these technologies and maybe it can help you:
"Google Maps Geolocation API" unlike Android's Location Manager API, can work in web browsers as well as the Android operating system. And Google Play Services Location API is mostly used by mobile app developers to gather information about verified users.

Since Google switched their pricing model, and Mobile Native Maps are still unlimited while Javascript SDK maps are limited to 28,000 per month as you can see
here.
Does anyone know which category react-native-maps falls under? Thanks
You can find answer in the documentation of react native maps
The actual map implementation depends on the platform. On Android, one has to use Google Maps, which in turn requires you to obtain an API key for the Android SDK.
On iOS, one can choose between Google Maps or the native Apple Maps implementation.
When using Google Maps on iOS, you need to also register for the iOS SDK and include the Google Maps library in your build.
source: https://github.com/react-community/react-native-maps/blob/master/docs/installation.md
As you can see in case of Android it uses Google Maps Android SDK, in case of iOS it can use Google Maps iOS SDK. The Google Maps JavaScript API is not used in react native maps. That means at the moment the usage is unlimited and free of charge as per Google Maps Platform price sheet.
I hope it clarifies your doubt.
Regardless of the platform I would like to launch Google Maps and optionally perform some actions like showing location, route etc
Google provides Google Maps URLs which allows you to do just that. You can build a universal, cross-platform URL to launch Google Maps and perform searches, get directions and navigation, and display map views and panoramic images. The URL syntax is the same regardless of the platform in use.
You don't need a Google API key to use Google Maps URLs.
Google Map URLs
Recently, in May 2017, Google launched the new Google Maps URLs API. You can read about this API in the official documentation
https://developers.google.com/maps/documentation/urls/guide
This API is intended to provide universal, cross-platform Google Maps URLs. So you can use it with websites, mobile apps, etc.
Search, directions, display map and display street view panorama modes are available in this API.
I hope this helps!
I have an application with a Google map. I traced the routes with address history to follow to go from one point to another. I would like to implement GPS service on my map, like Google Maps application mobile, which will go running for both voice and by visualization. My APP is in HTML5 and in javascript, not in native.
Basically, I would like to do this with Google Maps Api or something like that:
Thank you and sorry about my english.
Please check the Google Maps API for the recommended use of directions https://developers.google.com/maps/documentation/directions/
Alternatively if you have a Android / iOS App and want to open google directions through an intent, check the documentation for Google Maps Intents for Android or Google Maps URL Scheme for iOS respectively
I was browsing Foursquare recently and they have this neat feature where you can click "Bigger Map" on their map, and it plugs your location in to Google Maps directions to the venue. I was wondering how I could replicate the functionality. (A high level overview is sufficient, I just can't seem to find it in the docs.)
It's not in the docs because it's not a Maps function. If you're talking about the Google Maps API, which is what Foursquare uses, they're detecting position using your device. I'm guessing for browser operations, they're using HTML5 geolocation. Here's a demo of just plain geolocation: http://html5demos.com/geo. That will ask the user to share their location with the app. Once you have that, you plug it into the Google Maps API Directions Service.
Is there a https version of the google maps api v3? I have a site that uses https and am getting annoying mixed secure and non-secure content errors in IE. I read that in v2 you had to pay to get this, but haven't seen anything for v3.
Yesterday Google announced that sites may use the v3 API for free over https:
http://googlegeodevelopers.blogspot.com/2011/03/maps-apis-over-ssl-now-available-to-all.html
Try replacing
http://maps.google.com/maps
with
https://maps-api-ssl.google.com/maps
Update
As of March 2011
The Maps API v3, Static Maps API, and Maps API Web Services are now
available to all developers over https:
This is one of my big problems with Google Maps. If you want to access Google Maps javascript via https you have to sign up as a Google Maps Premier customer.
There is a Google Maps API issue on the topic with lots of mutinous comments, but the final word from Google is that they will not be supporting this functionality in the free API.
This particular problem is close to my heart as I have spent the last few days porting one of our projects over to Bing Maps (it does support https).
Google does allows https access for Maps API v3, Static Maps API, and Maps API Web Services.
But with one condition:
If your site uses SSL because you charge for access to your
application, or because your application is not publicly accessible to
all users, you must still purchase a Maps API Premier license.
