GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.

A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.

<blockquote>
 There are 3 location providers in Android. 
 
 They are:
 
 gps –> (GPS, AGPS): Name of the GPS location provider. This
 provider determines location using satellites. Depending on
 conditions, this provider may take a while to return a location fix.
 Requires the permission android.permission.ACCESS_FINE_LOCATION.
 
 network –> (AGPS, CellID, WiFi MACID): Name of the network
 location provider. This provider determines location based on
 availability of cell tower and WiFi access points. Results are
 retrieved by means of a network lookup. Requires either of the
 permissions android.permission.ACCESS_COARSE_LOCATION or
 android.permission.ACCESS_FINE_LOCATION.
 
 passive –> (CellID, WiFi MACID): A special location provider for
 receiving locations without actually initiating a location fix. This
 provider can be used to passively receive location updates when other
 applications or services request them without actually requesting the
 locations yourself. This provider will return locations generated by
 other providers. Requires the permission
 android.permission.ACCESS_FINE_LOCATION, although if the GPS is not
 enabled this provider might only return coarse fixes. This is what
 Android calls these location providers, however, the underlying
 technologies to make this stuff work is mapped to the specific set of
 hardware and telco provided capabilities (network service).
 
 The best way is to use the “network” or “passive” provider first,
 and then fallback on “gps”, and depending on the task, switch between
 providers. This covers all cases, and provides a lowest common
 denominator service (in the worst case) and great service (in the best
 case).

Now Android have Fused location provider

The Fused Location Provider intelligently manages the underlying location technology and gives you the best location according to your needs. It simplifies ways for apps to get the user’s current location with improved accuracy and lower power usage

Fused location provider provide three ways to fetch location

<ol>
<li>Last Location: Use when you want to know current location once.</li>
<li>Request Location using Listener: Use when application is on screen / frontend and require continues location.</li>
<li>Request Location using Pending Intent: Use when application in background and require continues location.</li>
</ol>

blocks|key|260704|text|这里有一些很好的答案。你可以采取的另一种方法是使用在线提供的一些免费SDK，如Atooma，tranql和Neura，它们可以与你的Android应用程序集成(集成只需不到20分钟)。除了给你用户的准确位置之外，它还可以让你对用户的活动有很好的洞察力。此外，其中一些电池的耗电量还不到你电池的1%25。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|260705|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). 
Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery

In my application I would like to determine the user's current location. I do however have a couple of questions in this regard:

<ol>
<li>There are different Location Providers, which one is the most accurate? The <a href="http://developer.android.com/reference/android/location/LocationManager.html#GPS_PROVIDER" rel="noreferrer">GPS Provider</a> or the <a href="http://developer.android.com/reference/android/location/LocationManager.html#NETWORK_PROVIDER" rel="noreferrer">Network Provider</a>?</li>
<li>In how far do those available provider differ? How do they function?</li>
<li>Could you please provide me with some code-snippets or tutorials on how to get started with implementing GPS functionality in my application?</li>
</ol>

Android Location Providers - GPS or Network Provider?

Android

在我的应用程序中，我想确定用户的当前位置。然而，在这方面，我确实有几个问题：有不同的位置提供商，哪一个最准确？或In这两个可用的提供程序有多大区别？如何在我的应用程序中实现function?Could功能？请为我提供一些代码片段或教程
