Google Play Location & Context Samples

The location and context APIs harness the sensors and signals of mobile devices to provide awareness of user actions and their environment, enabling delightful and engaging experiences that simplify user interactions, provide assistance, and help users to better understand themselves.

This repo contains the following samples:

• Activity Recognition (Kotlin) - Demonstrates the ActivityRecognitionApi to determine the user's current activity.

• AwarenessApisSampleKotlin (Kotlin) - Demonstrates use of the Awareness APIs to intelligently react to the current situation of the user.

• ForegroundLocationUpdates (Kotlin) - Get updates about a device's location using a bound foreground service.

• Geofencing (Java) - Create geofences and process enter and exit transitions.

• LocationAddress (Kotlin) - Use the Geocode API to display a device's location as an address.

• LocationUpdatesBackgroundKotlin (Kotlin) - Demonstrates the correct way to retrieve location updates in the background.

• SleepSampleKotlin (Kotlin) - Demonstrates use of the Sleep API to recognize a user's sleep activity.

Geofence transitions not triggered on all devices

I have been using the Google Geofencing Service on Android for quite some time now and I just found out that the geofence transitions are not triggered on all devices. I've always tested with my HTC Nexus 5 and HTC Desire 320. But now I can see that the same code does not work on an Asus Zenfone 2 nor a Samsung Galaxy Tab 4.

Geofencing samples link doesn't work...

Hi, when I try to open this link https://github.com/googlesamples/android-play-location/tree/master/Geofences from readme, I receive 404 page error...

When I click on https://github.com/googlesamples/android-play-location/tree/master/Geofencing it works.

Dummy link, a simple wrong reference :-)

SETTINGS_CHANGE_UNAVAILABLE when locations are enabled

Steps to reproduce:

1. Enable Airplane mode (-> cell operator disabled)
2. Disable Wi-Fi.
3. Enable locations.
4. Start "LocationSettings" example from this repositoty.

Expected result:
LocationSettingsStatusCodes.SUCCESS or LocationSettingsStatusCodes.RESOLUTION_REQUIRED in onResult callback, because we're still able to receive updates for the same LocationRequest object.

Actual result:
LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE. However, we still can requestLocationUpdates and receive them.

Gradle, android gradle plugin and build tools are out-of-date.

The current version in project is

• gradle 2.5
• buildTools 23.0.1
• android gradle plugin 1.3.1

The latest version is

• gradle 2.14.1
• buildTools 24.0.2
• android gradle plugin 2.1.3

Solution
Update all of them to latest version.

How to enable Location when running app on device emulator

I get the error: "No Location detected. Make sure location is enabled on device."

How do you enable location?

I tried adding android geo api key to AndroidManifest.xml, ran the emulator and went into settings -> Personal -> Location and checked if on is available but it's still not showing anything other than this error message.

App crashes on load

I am using https://github.com/googlesamples/android-play-location/tree/master/LocationUpdates Sample project to test whether app can get coordinates or not with only Wi-Fi enabled on Samsung Tab 4. But app crashes always.

I think app crashes because mCurrentLocation is always null when GPS is disabled and Wi-Fi is enabled and connected to active internet connection. Seems like FusedLocationApi failed to get location with just Wi-Fi enabled. And i think it won't call onLocationChanged() method ever.

It works fine when GPS is enabled.

Device info
Samsung Galaxy Tab® 4 10.1
Android OS: 5.0.2

LocationAddress - "Address found" but no address shows

I try the project "LocationAddress".
After I push the button "FETCH ADDRESS", "Address found" shows but no address appears.
I find the code in FetchAddressIntentService.java line129

for(int i = 0; i < address.getMaxAddressLineIndex(); i++) {
     addressFragments.add(address.getAddressLine(i));
 }

The value of address.getMaxAddressLineIndex() is 0 when there's one element in the HashMap address.mAddressLines [index 0: "some address line value" ], so the program didn't step into the for loop. The ArrayList addressFragments doesn't get the address.

Actually it seems like I can't receive mock locations while using FusedLocationProviderApi at all. I pulled this repo to check what I'm doing wrong.

Btw it seems like assertEquals parameters in said test are in wrong order (first actual, then expected, should be the other way around).

About never Option

can I disable never option in dialog ??

Giving time out exception

I am getting java.io.IOException: Timed out waiting for response from server, while getting address from Location.

Failed to crunch file

Hi there,
I have a problem with samplecode and google-play dependences and drawable icons.
Every time that I compile the project this error happens with icons:

Error: com.android.builder.internal.aapt.AaptException: Failed to crunch file 

C:\Users\Francis\Documents\projects\mobile\android-play-location\Geofencing\Application\build\intermediates\exploded-aar\com.google.android.gms\play-services-base\8.4.0\res\drawable-mdpi\common_google_signin_btn_text_dark_normal.9.png into

The icons exists but I not run my project because of that.
What's going wrong?

Running the App

Hi,

Do i need to install this app onto 2 devices to test its functionality?

May i ask developers to provide screenshots of the app running and performing what it is supposed to?
thanks.

GoogleApiClient not yet connected issue

Hi,

When clicking the "request updates" button in the app, I always get the toast "GoogleApiClient not yet connected. TryAgain."
I cloned the repo and installed as is on a Galaxy Note running Marshmallow 5.0. Couldn't find a fix yet, any ideas?

Use WakefulBroadcastReceiver instead of IntentService for handling background triggers to the app

I can't understand why you use IntentService for handling all stuff which happens in background.

Please note that device may go asleep (and it actually does go asleep) during IntentService is doing it's job.

Use WakefulBroadcastReceiver for this purpose which then triggers IntentService.

This issue applies to all examples, in particular GeofenceTransitionsIntentService and DetectedActivitiesIntentService.

Request location updates from Service

All of the samples show location updates being requested from an activity. Can this logic be moved to a IntentService, that way in the background you can monitor a user's location.

Specifically I want to use this so that I can dynamically remove and then add geofences as a users location significantly (the user moves more than 20 miles) changes.

GPS Bug on several older mobile devices

I just tried the BasicLocationSample and it does not work on my Samsung GT-S7562 device. I went to a showroom and tested the same on several devices and it doesn’t work on Xiaomi redmi 2, Galaxy core prime as well. The sample works fine on newer models from these manufacturers. I even tested it on my OnePlus 2 and it works perfectly well.

There appears to be a bug that prevents GPS working on several devices and that needs to be addressed. I’ve been trying to find a solution so I figured trying out this Google Sample hoping that at least this would work coz it’s from the makers of Android but in vain. Basically it shows No location detected. Make sure location is enabled on the device. even with the location enabled.

Testing the LocationUpdates sample on the same devices gave NullPointException at updateUI() function regardless of whether Location is enabled or disabled. On the newer devices like the OP2, the NullPointerException appears only when Location is disabled and shows updates and works fine when Location is enabled.

Cannot run MainActivityTest

I get an error:

FAILURE: Build failed with an exception.

• What went wrong:

Issues with GMS status codes

When GMS package is disabled (uninstalled all updates and disabled) the error dialog says GMS needs to be updated. When the user chooses to resolve this it opens Play Store app which crashes immediately. Because GMS package is disabled. This check should be performed before checking GMS version.

Head Bang !...Cant use and run them in Eclipse ?

Almost spent an hour trying fixes for the same. ?

location is not working on General Mobile e Tab 3

Hi,

When I run my location code on cell phone I don't have any problem, but When I run it on General Mobile Tablet my location can not founded. Can you help me tihs about issue.

Thanks for your interest.

Reasoning behind calling connect() / disconnect() on the googleApiClient in the onStart()/onStop() methods

Wouldn't it make more sense to have them called in the onResume() / onPause() methods?
I would expect that if the user pauses the app to change the location settings (or any external event occurs), the change will be visible when he returns to the app.

Google play service's v8.1.0's location listener is leaking the activity or service it is attached to

(Moving this issue from playgames to here on behalf of @youfacepalm)

I am not sure if this is the right place to report this since I could not find any common "Play Services" issue reporting forum anywhere.. If there is such an issue tracker, please give me the link. Thanks

The latest version of Google play service's (8.1.0 as of writing this report) LocationListener is leaking the activity or service it is attached to according to LeakCanary version 1.3.1.

Steps to reproduce

-Download the LocationUpdate Sample from google's repo (https://github.com/googlesamples/android-play-location/tree/master/LocationUpdates)

-Update the gradle to include the latest version of Google play services (8.1.0, the sample contains Google play services version 6.5.87 which had no issues during my testing)

Add a regular activity (name it "TestActivity" for example) to the project

from the MainActivity, after starting the location update, go to the newly added (startActivity()) TestActivity while finishing the MainActivity (it doesn't matter if you stop or did not stop the location updates)

after about 5 seconds you will see LeakCanary reporting that the MainActivity has leaked (if it is added to the project)

Is possible to use LocationSettings and Geofencing?

I'm trying to do this since 7 days with no results...

The problem is ResultCallback, for geofencing I need ResultCallback while for LocationSettings I need ResultCallback, is there a way to do this?

I appreciate some tips...

Thanks for your support :)

Geofence Testing

What is the best way to test Geofencing? I wrote a blog article on this subject matter

http://lawloretienne.github.io/blog/

but now am having issues with the Google Maps app on the Genymotion device. Aside from physically going in and out of Geofences, what are the alternatives?

Also, I have set up geofences for stores inside a mall but don't see them triggering a notification. Do geofences still work inside of a mall?

mLastLocation is null when set "targetSdkVersion 23"

mLastLocation is null when set "targetSdkVersion 23"
Device: nexus 5 with android 6, if it does matter

Basic Location Sample does not give accurate location

I changed permission from Coarse to Fine, even then location i.e. lat & lon picked are incorrect and far way from my real location. What else is required to get exact location like Google Maps

mGeofencePendingIntent never set

It seems that mGeofencePendingIntent is never set to anything except null (also in https://developer.android.com/training/location/geofencing.html).

A good example of background service getting location updates

Please I need help.

I'm facing a problem here. It is impossible to find A GOOD EXAMPLE of how create a service that must run in background and receive location updates. Also, all examples on developer.android.com are terrible, any one of them really works.

My app aim is get location updates in background, something which looks like so simple but unfortunately I could not find any good example about how to do it.

getLastLocation always returning null

scenarios:

1. when we enable the location it returns location
2. when we disable the location it returning null.

GEOFENCE_TOO_MANY_PENDING_INTENTS, GMS officially useless, 5 limit

Please remove the ridiculously low limit of max 5 geofences when using the PendingIntent method. Geofencing in GMS has, a reasonable, limit of 100 geofences, why restrict the use of the more background service friendly PendingIntent method to only 5, it should be 100 as well.

We can no longer justify using the Google Play Services location API, there's just too many issues, even if it claims to be more accurate and battery friendly. Reverting back to the proximity alarm API.

Activity.RESULT_OK not being called on 4.1 and 4.2 after Clicking YES in SettingsApi Use Location Dialog

I was running the LocationSettings sample app on a 4.1 device.

But If I click "Yes" or "No", always Activity.RESULT_CANCELED is being called. As per documentation Activity.RESULT_OK needs to be called.

Activity.RESULT_OK is being called in other Android versions. The problem is happening only in 4.1 and 4.2

Geofence does not activate on entering or leaving, only activates when another request location

I have used the sample app and also followed the documentation on the Android developer site and i keep getting the same results.

The geofence does not trigger when i enter or leave the area around the geofence. To force the geofence to activate i have to open an app such as maps that polls for location updates then i get the geofence triggering.

I had to open an app that have a Google Places Picker then the geofence triggers. How do i resolve this since i do not need to keep polling for location updates and it looks as if i need to do that for the geofence to trigger?

Moving all location API code inside a helper class

In all samples the location API code is written inside a activity. wouldn't it be better if we move all logic inside a helper class. This way any activity can request the location by calling a function defined in helper class.

Warning on line 121 of GeofenceTransitionsIntentService.java

Unchecked call to 'add(E)' as a member of raw type 'java.util.ArrayList'

I am using Android Studi0 1.2.1.1, what's the best way to fix this?

FusedLocationApi cannot retrieve satellites number as with android.location.LocationManager

As described in the documentation, I changed my application to use the new FusedLocationApi instead of the old android.location.LocationManager.

Everything works fine, but before, when I was using the android.location.LocationManager listener to retrieve the updates of the locations:

    @Override
    public void onLocationChanged(Location location) {
    }

inside the object "Location" I could see a list of Bundles (extras) like the "satellites", giving me information about the number of satellites used to retrieve that information.

Now, with the new service I cannot retrieve that information because the object Location.getExtras() is null.

I am using the current 9.4 google play services version.

Null Last known location when using a coarse location permission

In my case

• target SDK: 21
• build tools version: 21.1.2
• play-services version: 6.5.87
• running the sample on a Lollipop physical device

I'm always getting a null last known location with ACCESS_COARSE_LOCATION permission in the manifest file. Only getting a valid object when using ACCESS_FINE_LOCATION.

Geofence issue

Sometime geofence does not provide result after connection established.
Specially when we call action from service.

ActivityRecognition does not work in background on HTC M8 with Android 5.0.1

I'm using compile 'com.google.android.gms:play-services-location:8.1.0'.

It seems that ActivityRecognition sample does not work and is not sending any updates when device goes asleep. It does not work even if I use WakefulBroadcastReceiver mentioned in #28.

I've added notification to be fired from when DetectedActivitiesIntentService is triggered.

It works perfect on Sony C5303 Android 4.3 (notifications are but it does not work on HTC M8 Android 5.0.1 (i.e. notifications stop coming as soon as I press power button).

requestLocationUpdates with PendingIntent including extras not working, no Location

When using requestLocationUpdates() with a PendingIntent which include additional extras, the received "location update" Intent contains no Location, neither in the LocationResult or the deprecated FusedLocationProviderApi.KEY_LOCATION_CHANGED extra.

Disable location and Activity Recognizing sample still works

Hi,

In the ActivityRecognition's introduction, there is a sentence "To run this sample, location must be enabled." But when I disable "Android Location" ActivityRecognition sample still works. I just want to know is there any different in application behavior when I turn on or turn off location. Why it still work?
And the last question is which sensors ActivityRecognition API use?

Is there any way to use "Step Detector Sensor" and "Step Counter Sensor" to detect current user activity?

Thank you in advance.

The LocationUpdates sample test failed in China, i need your help.

GoogleApiClient already connected, and call requestLocationUpdates() method, but LocationListener no callback.

How to load dynamically Geofences?

Hi,
I have a problem...in this sample you use geofence from Constant...unfortunately i'm not able to load geofences dynamically :-(

Maybe I wrong something...

In onCreate method:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);

    // Empty list for storing geofences.
    mGeofenceList = new ArrayList<Geofence>();

    // Initially set the PendingIntent used in addGeofences() and removeGeofences() to null.
    mGeofencePendingIntent = null;

    geofencePointsRequest(this, null, null);
}

Volley request to retrieve data

public void geofencePointsRequest(final Context context, Map<String,String> params, final ProgressDialog pDialog){
webService = new WebService();

CustomArrayRequest jsonObjReq = new CustomArrayRequest(
        Request.Method.GET,
        WebServiceUrl.POINTS,
        params,
        new Response.Listener<JSONArray>() {
            @Override
            public void onResponse(JSONArray response) {
                ArrayList<Point> points = webService.getPoints(response);
                populateGeofenceList(points);
            }
        },

        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                String errorHandler = webService.getError(error);
                int status = (error.networkResponse.statusCode != 0) ? error.networkResponse.statusCode : 0;
                Toast.makeText(context, "Code : " + status + " - Error : " + errorHandler, Toast.LENGTH_LONG).show();
            }
        }) {

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        return webService.getHeaders();
    }
};

VolleySingleton.getInstance(context).addToRequestQueue("pointsRequest", jsonObjReq);
}

        logSecurityException(securityException);

}

I create a list of geofences (from data parsed)

public void populateGeofenceList(ArrayList<Point> points) {
    for (int i=0; i<points.size(); i++) {
        mGeofenceList.add(new Geofence.Builder()
                .setRequestId(pins.get(i).getShortId())
                .setCircularRegion(
                        points.get(i).getLocation().getCoordinates().latitude,
                        points.get(i).getLocation().getCoordinates().longitude,
                        points.get(i).getLocation().getRadius()
                )
                .setExpirationDuration(Geofence.NEVER_EXPIRE)
                .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
                .build());
    }

    buildGoogleApiClient();
}

Thanks in advance :-)

how to fix it?

connecting to google play services

I try to connect to google play services using the code of this sample.
But it does n`t connect and return connection result code 8(Internal error occurred.retrying should resolve the problem) and code 2(The installed version of Google Play services is out of date.
The calling activity should pass this error code to getErrorDialog(int, Activity, int) to get a localized error dialog that will resolve the error when shown.).
I cant understand error code 8. and I installed the latest version of google play services but i still receive error code 2.
Can you help me to resolve this problem and connect to google play services?

Why location must be enabled?

Hi all,
I remember in previous google play services version was possible to instantiate a geofence without location enabled (only with Wi-Fi for example).

Why in this sample do not work?

I allready read "To run this sample, location must be enabled.", but in this way the battery becoming low in small time.

Thanks
