+
+<h2 id="RequestGeofences">Set up for Geofence Monitoring</h2>
 <p>
     The first step in requesting geofence monitoring is to request the necessary permission.
     To use geofencing, your app must request
     {@link android.Manifest.permission#ACCESS_FINE_LOCATION ACCESS_FINE_LOCATION}. To request this
     permission, add the following element as a child element of the
 <code><a href="{@docRoot}guide/topics/manifest/manifest-element.html">&lt;manifest&gt;</a></code>
-    element:
+    element in your app manifest:
 </p>
 <pre>
 &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/&gt;
 </pre>
-<!-- Check for Google Play services -->
-<h3>Check for Google Play Services</h3>
-<p>
-    Location Services is part of the Google Play services APK. Since it's hard to anticipate the
-    state of the user's device, you should always check that the APK is installed before you attempt
-    to connect to Location Services. To check that the APK is installed, call
-<code><a href="{@docRoot}reference/com/google/android/gms/common/GooglePlayServicesUtil.html#isGooglePlayServicesAvailable(android.content.Context)">GooglePlayServicesUtil.isGooglePlayServicesAvailable()</a></code>,
-    which returns one of the
-    integer result codes listed in the API reference documentation. If you encounter an error,
-    call
-<code><a href="{@docRoot}reference/com/google/android/gms/common/GooglePlayServicesUtil.html#getErrorDialog(int, android.app.Activity, int)">GooglePlayServicesUtil.getErrorDialog()</a></code>
-    to retrieve localized dialog that prompts users to take the correct action, then display
-    the dialog in a {@link android.support.v4.app.DialogFragment}. The dialog may allow the
-    user to correct the problem, in which case Google Play services may send a result back to your
-    activity. To handle this result, override the method
-    {@link android.support.v4.app.FragmentActivity#onActivityResult onActivityResult()}
 
-</p>
-<p class="note">
-    <strong>Note:</strong> To make your app compatible with
-    platform version 1.6 and later, the activity that displays the
-    {@link android.support.v4.app.DialogFragment} must subclass
-    {@link android.support.v4.app.FragmentActivity} instead of {@link android.app.Activity}. Using
-    {@link android.support.v4.app.FragmentActivity} also allows you to call
-    {@link android.support.v4.app.FragmentActivity#getSupportFragmentManager
-    getSupportFragmentManager()} to display the {@link android.support.v4.app.DialogFragment}.
-</p>
 <p>
-    Since you usually need to check for Google Play services in more than one place in your code,
-    define a method that encapsulates the check, then call the method before each connection
-    attempt. The following snippet contains all of the code required to check for Google
-    Play services:
+    If you want to use an {@link android.app.IntentService} to listen for geofence transitions,
+    add an element specifying the service name. This element must be
+    a child of the <code><a href="{@docRoot}guide/topics/manifest/application-element.html">
+    &lt;application&gt;</a></code> element:
+</p>
+
+<pre>
+&lt;application
+   android:allowBackup=&quot;true&quot;&gt;
+   ...
+   &lt;service android:name=".GeofenceTransitionsIntentService"/&gt;
+&lt;application/&gt;
+</pre>
+
+<p>To access the location APIs, you need to create an instance of the
+  Google Play services API client. To learn how to connect your client, see
+  <a href="{@docRoot}training/location/retrieve-current.html#play-services">Connect
+  to Google Play Services</a>.</p>
+
+<h2 id="CreateAdd">Create and Add Geofences</h2>
+
+<p>Your app needs to create and add geofences using the location API's builder class for
+ creating Geofence objects, and the convenience class for adding them. Also, to handle the
+ intents sent from Location Services when geofence transitions occur, you can define a
+ {@link android.app.PendingIntent} as shown in this section.
+</p>
+
+<h3>Create geofence objects</h3>
+
+<p>
+    First, use <code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.Builder.
+    html">Geofence.Builder</a></code> to create a geofence, setting the desired radius, duration, and
+    transition types for the geofence. For example, to populate a list object named
+    {@code mGeofenceList}:
+    </p>
+
+<pre>
+mGeofenceList.add(new Geofence.Builder()
+    // Set the request ID of the geofence. This is a string to identify this
+    // geofence.
+    .setRequestId(entry.getKey())
+
+    .setCircularRegion(
+            entry.getValue().latitude,
+            entry.getValue().longitude,
+            Constants.GEOFENCE_RADIUS_IN_METERS
+    )
+    .setExpirationDuration(Constants.GEOFENCE_EXPIRATION_IN_MILLISECONDS)

-<p>
-    Snippets in the following sections call this method to verify that Google Play services is
-    available.
-</p>
-<p>
-    To use geofencing, start by defining the geofences you want to monitor. Although you usually
-    store geofence data in a local database or download it from the network, you need to send
-    a geofence to Location Services as an instance of
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.html">Geofence</a></code>,
-    which you create with
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.Builder.html">Geofence.Builder</a></code>.
-    Each
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.html">Geofence</a></code>
-    object contains the following information:
-</p>
-<dl>
-    <dt>Latitude, longitude, and radius</dt>
-    <dd>
-        Define a circular area for the geofence. Use the latitude and longitude to mark a location
-        of interest, and then use the radius to adjust how close the user needs to approach the
-        location before the geofence is detected. The larger the radius, the more likely the
-        user will trigger a geofence transition alert by approaching the geofence. For example,
-        providing a large radius for a geofencing app that turns on lights in the user's house as
-        the user returns home might cause the lights to go on even if the user is simply passing by.
-    </dd>
-    <dt>Expiration time</dt>
-    <dd>
-        How long the geofence should remain active. Once the expiration time is reached, Location
-        Services deletes the geofence. Most of the time, you should specify an expiration time, but
-        you may want to keep permanent geofences for the user's home or place of work.
-    </dd>
-    <dt>Transition type</dt>
-    <dd>
-        Location Services can detect when the user steps within the radius of the geofence ("entry")
-        and when the user steps outside the radius of the geofence ("exit"), or both.
-    </dd>
-    <dt>Geofence ID</dt>
-    <dd>
-        A string that is stored with the geofence. You should make this unique, so that you can
-        use it to remove a geofence from Location Services tracking.
-    </dd>
-</dl>
-<h3>Define geofence storage</h3>
-<p>
-    A geofencing app needs to read and write geofence data to persistent storage. You shouldn't use
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.html">Geofence</a></code>
-    objects to do this; instead, use storage techniques such as databases that can store groups of
-    related data.
-</p>
-<p>
-    As an example of storing geofence data, the following snippet defines two classes that use
-    the app's {@link android.content.SharedPreferences} instance for persistent storage. The class
-    {@code SimpleGeofence}, analogous to a database record, stores the
-    data for a single
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.html">Geofence</a></code>
-    object in a "flattened" form. The class {@code SimpleGeofenceStore}, analogous to a database,
-    reads and writes {@code SimpleGeofence} data to the
-    {@link android.content.SharedPreferences} instance.
-</p>

-    In addition to the {@link java.util.List} of
-<code><a href="{@docRoot}reference/com/google/android/gms/location/Geofence.html">Geofence</a></code>
-    objects you want to monitor, you need to provide Location Services with the
-    {@link android.content.Intent} that it sends to your app when it detects geofence
-    transitions.
-<h4>Define a Intent for geofence transitions</h4>
+<p>In many cases, it may be preferable to use instead <code><a href="{@docRoot}reference/com/google/android/gms/location/GeofencingRequest.html#INITIAL_TRIGGER_DWELL">
+    INITIAL_TRIGGER_DWELL</a></code>,
+    which triggers events only when the user stops for a defined duration within a geofence.
+    This approach can help reduce "alert spam" resulting from large numbers notifications when a
+    device briefly enters and exits geofences. Another strategy for getting best results from your
+    geofences is to set a minimum radius of 100 meters. This helps account for the location accuracy

-    Now you have all the code you need to send a request to monitor geofences to Location
-    Services.
-</p>
-<!-- Send the monitoring request -->
-<h3 id="requestmonitoring">Send the monitoring request</h3>
-<p>
-    Sending the monitoring request requires two asynchronous operations. The first operation gets a
-    location client for the request, and the second makes the request using the client. In both
-    cases, Location Services invokes a callback method when it finishes the operation. The best way
-    to handle these operations is to chain together the method calls. The following snippets
-    demonstrate how to set up an activity, define the methods, and call them in the proper order.
-</p>
-<p>
-     First, modify the activity's class definition to implement the necessary callback interfaces.
-     Add the following interfaces:
-</p>
-<dl>
-    <dt>
-<code><a href="{@docRoot}reference/com/google/android/gms/common/GooglePlayServicesClient.ConnectionCallbacks.html">ConnectionCallbacks</a></code>
-    </dt>
-    <dd>
-        Specifies methods that Location Services calls when a location client is connected or
-        disconnected.
-    </dd>
-    <dt>
-<code><a href="{@docRoot}reference/com/google/android/gms/common/GooglePlayServicesClient.OnConnectionFailedListener.html">OnConnectionFailedListener</a></code>
-    </dt>
-    <dd>
-        Specifies a method that Location Services calls if an error occurs while attempting to
-        connect the location client.
-    </dd>
-    <dt>
-<code><a href="{@docRoot}reference/com/google/android/gms/location/LocationClient.OnAddGeofencesResultListener.html">OnAddGeofencesResultListener</a></code>
-    </dt>
-    <dd>
-        Specifies a method that Location Services calls once it has added the geofences.
-    </dd>
-</dl>
-<p>
-    For example:
-</p>
-<pre>
-public class MainActivity extends FragmentActivity implements
-        ConnectionCallbacks,
-        OnConnectionFailedListener,
-        OnAddGeofencesResultListener {
-    ...
-}
-</pre>
-<h4>Start the request process</h4>
-<p>
-    Next, define a method that starts the request process by connecting to Location Services.
-    Mark this as a request to add a geofence by setting a global variable. This allows you to
-    use the callback
-<code><a href="{@docRoot}reference/com/google/android/gms/common/GooglePlayServicesClient.ConnectionCallbacks.html#onConnected(android.os.Bundle)">ConnectionCallbacks.onConnected()</a></code>
-    to add geofences and to remove them, as described in succeeding sections.
-</p>
-<p>
-<p>
-    To guard against race conditions that might arise if your app tries to start another request
-    before the first one finishes, define a boolean flag that tracks the state of the current
-    request:
-</p>

     When Location Services detects that the user has entered or exited a geofence, it

-    To identify the {@link android.app.IntentService} to the system, add a
-    <code><a href="{@docRoot}guide/topics/manifest/service-element.html">&lt;service&gt;</a></code>
-    element to the app manifest. For example:
-</p>
-<pre>

 <!--
     Remove Geofences
  -->
 <h2 id="StopGeofenceMonitoring">Stop Geofence Monitoring</h2>
-<p>
-    To stop geofence monitoring, you remove the geofences themselves. You can remove a specific
-    set of geofences or all the geofences associated with a {@link android.app.PendingIntent}. The
-    procedure is similar to adding geofences. The first operation gets a location
-    client for the removal request, and the second makes the request using the client.
+
+<p>Stopping geofence monitoring when it is no longer needed or desired can help save battery
+    power and CPU cycles on the device. You can stop geofence monitoring
+    in the main activity used to add and remove geofences; removing a geofence stops it
+    immediately. The API provides methods to
+    remove geofences either by request IDs, or by removing geofences associated with a given
+    {@link android.app.PendingIntent}.
 </p>
 <p>
-    The callback methods that Location Services invokes when it has finished removing geofences
-    are defined in the interface
-<code><a href="{@docRoot}reference/com/google/android/gms/location/LocationClient.OnRemoveGeofencesResultListener.html">LocationClient.OnRemoveGeofencesResultListener</a></code>. Declare
-    this interface as part of your class definition, and then add definitions for its two methods:
-</p>
-<dl>
-    <dt>
-<code><a href="{@docRoot}reference/com/google/android/gms/location/LocationClient.OnRemoveGeofencesResultListener.html#onRemoveGeofencesByPendingIntentResult(int, android.app.PendingIntent)">onRemoveGeofencesByPendingIntentResult()</a></code>
-    </dt>
-    <dd>
-        Callback invoked when Location Services finishes a request to remove all geofences made
-        by the method
-<code><a href="{@docRoot}reference/com/google/android/gms/location/LocationClient.html#removeGeofences(android.app.PendingIntent, com.google.android.gms.location.LocationClient.OnRemoveGeofencesResultListener)">removeGeofences(PendingIntent, LocationClient.OnRemoveGeofencesResultListener)</a></code>.

-    </dt>
-    <dd>
-        Callback invoked when Location Services finished a request to remove a set of geofences,

-    String&lt;List&gt; mGeofencesToRemove;
-</pre>
-<p>
-    Next, define a list of geofences you want to remove. For example, this snippet removes the

-    The next lesson,
-    <a href="activity-recognition.html">Recognizing the User's Current Activity</a>, shows you how
-    to request and receive activity updates. At regular intervals, Location Services can send you
-    information about the user's current physical activity. Based on this information, you can
-    change your app's behavior; for example, you can switch to a longer update interval if you
-    detect that the user is walking instead of driving.
