A drop-in replacement for Google Play services location APIs for Android

Deprecated

This project is deprecated for use and not recommended for modern Android applications. The maintainers are no longer available to maintain it and the implementation is now fairly divergent from modern Android requirements. We appreciate everyone who has contributed to this project in the past. Thank you!

Lost

Location Open Source Tracker (for Android)

Usage

This project seeks to provide an open source alternative to the Google Play services location APIs that depends only on the Android SDK. It provides 1:1 replacements for the FusedLocationProviderApi, GeofencingApi, and SettingsApi.

Lost operates by making calls directly to the LocationManager. Lost can run on any Android device running API 15 or higher regardless of whether or not it supports the Google Play ecosystem.

Set up:

• Installation
• Upgrading 1.x to 2.0
• Upgrading 2.x to 3.0
• Getting Started
• Getting the Last Known Location
• Receiving Location Updates
• Mock Locations & Routes
• Changing Location Settings
• Creating and Monitoring Geofences

Sample

For a working example please refer to the Sample App.

lost's Issues

Fix tests using Thread.sleep(100)

Description

A number of tests are currently ignored due to intermittent failures. These tests all depend on concurrency used by MockEngine to deliver mock location updates from a GPX trace file. We need to find a better way to test the behavior of FusedLocationProviderApi.setMockTrace(File) without the use of Thread.sleep(100).

Steps to Reproduce

Remove all @Ignore("Intermittently failing. Find a better way to test without Thread.sleep(100)") annotations and run tests.

Lost & Android Version

LOST 1.1.1

Publish documentation

Look into using gh-pages or github wiki

Add pending intent example to sample app

Implement getLocationAvailability and onLocationAvailability

Currently LOST provides no way to determine if a devices location services are enabled.

The Google Play API provides LocationServices.FusedLocationApi.getLocationAvailability() and LocationCallback.onLocationAvailability().

Implement getLocationAvailability and SettingsApi

Currently LOST provides no way to determine if a devices location services are enabled.

The Google Play API provides LocationServices.FusedLocationApi.getLocationAvailability() and LocationCallback.onLocationAvailability()

Further to this LOST is also missing the SettingsApi which provides a dialog to request the user enable the location services.

Make .gpx speed list optional

Currently, NodeList speedList is mandatory or the app will crash while mocking the file. It should be a trivial modification to make it optional.

Most tracks available on openstreetmap lack speed tags, and the current workaround is to append a large number of <speed>0</speed> to the track segment.

Possibly related: it would be nice to make a gpx extension allowing accuracy, since this might be important while testing an app. Also see #37.

throw IllegalStateException when trying to use LostApiClient before connect() called

Description

Like play services does, we should throw a more specific exception when a user tries to use the LocationServices APIs before their client has been connected. Currently a NPE is thrown.

Add sample app to collect location data and export GPX file

Also provide integration for automatic upload to http://www.openstreetmap.org/traces?

Location listener demo crashes on first launch

Description

After installing demo app and launching for the first time if you navigate to the "LocationListener" demo activity the app crashes. User is never prompted to agree to location permissions.

Steps to Reproduce

1. Uninstall demo app (if installed)
2. Install demo app
3. Launch and navigate to FusedLocationApi > LocationListener example
4. Runtime permission dialog will not be displayed and app will force quit

Lost & Android Version

Lost 1.1.2-SNAPSHOT (local build on master)
Android 6.0.1

Support multiple location clients

We should explore the feasibility of supporting multiple location clients from multiple threads and/or processes.

This primary use case would be for a single application if the UI thread and a service thread both needed to register for location updates via separate clients.

The secondary and potential future use case would be to allow a shared instance of lost to run in a background service that could be used by more than one application.

Javadoc fails on Circle CI (master)

https://circleci.com/gh/mapzen/LOST/212

Make FusedLocationApi and GeofencingApi fields final.

Static fields that provide entry point to LocationServices should not be able to be modified by the client app.

Implement SettingsApi

LOST is missing the SettingsApi which provides a dialog to request the user enable the location services.

Unable to register for network updates

When I try to implement LOST library, I receive this exception: (I am using Genymotion emulator for Android API 21, GPS is turned on and the example app is working properly)

'
FusionEngine﹕ Unable to register for network updates.
java.lang.IllegalArgumentException: provider doesn't exist: network
'

This exception can be seen, when calling 'LocationServices.FusedLocationApi.requestLocationUpdates(locationRequest, mLocationListener);'

Of course, before this I run 'mLOSTClient = new LostApiClient.Builder(mContext).build();' and then 'mLOSTClient.connect();'. and listener is also initialized.

What should I do?

Remove location permissions from library

The LOST library manifest should not include permissions ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION. It should be the responsibility of client applications to include necessary permissions in its manifest based on usage.

Requires permission annotations should be added to the appropriate methods in the FusedLocationProviderApi.

    @RequiresPermission(
        anyOf = {"android.permission.ACCESS_COARSE_LOCATION", "android.permission.ACCESS_FINE_LOCATION"}
    )

Check if connected in LostApiClient#connect()

Avoid creating a new instance of FusedLocationProviderApiImpl if already connected. Registers duplicate listeners on the LocationManager and old instances are not properly cleaned up.

GoogleApiClient and LostApiClient differences

Hey guys,

Nice work implementing FusedLocation API! Thanks for it. I was going through the code base and it seemed like the FusionEngine just takes care of switching between NETWORK, GPS and PASSIVE location providers based on conditions?

GoogleApiClient implements additional strategies right? Like using Sensor data as a means to accurate the location and also battery saving strategies. Are those things in pipeline?

Thanks again!

Q: isProviderEnabled & onProviderDisabled/Enabled callbacks

Here is a little question, I know this is not the way how the fused location provider works, but is there a way to receive a status of enabled providers and get appropriate callbacks or I should request android.location directly?

Return PendingResult for GeofencingApi

Enforce one-to-one relationship for requests and listeners

Each LocationRequest should have only one LocationListener and each LocationListener should be associated with only one LocationRequest.

This also implies that each request/listener pair would have its own FusionEngine using the current architecture and that engine would not be re-used for other requests or listeners.

Alternatively we could adopt a model that uses a single FusionEngine for all requests/listeners. This is how it's performed in the Android framework and would require implementing some form of request bundling.

Either way we decide to implement this it should simplify the logic required in FusedLocationProviderApiImpl (especially when toggling mock mode) and better match the behavior of the [play services APIs](https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderApi#requestLocationUpdates%28com.google.android.gms.common.api.GoogleApiClient, com.google.android.gms.location.LocationRequest, com.google.android.gms.location.LocationListener%29).

Is orientation provided?

For instance, with google maps user can change the phone orientation (phone is oriented to the west/east/north etc) and the angle of arrow on a map will be changed. Is this possible with LOST? Or, if not, maybe you could advise me, how to achieve this?

Thanks in advance for help.

Geofencing intent should have a GeofencingEvent extra

Description

Pending intents that are sent by a proximity alert trigger should attach a GeofencingEvent extra that has been populated with the triggering geofences, location, and transition.

Steps to Reproduce

1. Register a Geofence using the Geofencing API.
2. When the proximity alert is triggered the PendingIntent returned is missing the GeofencingEvent extra.

Could not run de lost-sample project

Hi !
I m imported the lost-sample project to Android Studio and deploy the application to my device GT-N7100.

When the app starts it just give me the follow error message: SettingsActivity}: android.view.InflateException: Binary XML file line #5: Error inflating class com.mapzen.prefsplus.EditIntPreference (bellow is the full error).

I already tried to use the lib with grandle, and after this download the jar to the libs folder... nothing works...

I would really appreciate if you guys help me on this. I liked the lib and it would be nice to use it on one of my projects.

Thanks,

Elcio A.

Support for Geofences?

Is there any intention to add support for Geofences and the Geofence API?

Background service

Explore the option of running the fused location provider in a background service.

Implement transition type

Description

Geofence.Builder should allow setting of transition types. Alerts should only be generated for the specified transitions.

Populate bearing data in mock GPX replay locations

Can be calculated using previous and current coordinates.

http://developer.android.com/reference/android/location/Location.html#bearingTo(android.location.Location)

getLastLocation() throws SecurityException on API 23+

Unfortunately we need to check if the ACCESS_FINE_LOCATION permission is granted every time we call this function.
Is this an intended behavior or some improvement is possible?

Process: com.amayatsky.test, PID: 5948 java.lang.SecurityException: "passive" location provider requires ACCESS_FINE_LOCATION permission.

Implement checkstyle

Run for all builds on Circle CI.

Style based on https://github.com/mapzen/open/blob/master/checkstyle.xml

Join forces with microg project?

migrog (ug) are trying to create a drop-in replacement for parts of the Google Service Framework. I feel like they would really appreciate you expertise on this. Seems like you're working on a similar projects :)

Location updates via PendingIntent

Manage multiple location listeners in FusedLocationProviderApi

Currently, only one LocationListener can be register at a given time in the implementation of the FusedLocationProviderApi (the FusedLocationProviderApiImpl). It would be nice to have a list of listeners.

The reason: I currently develop an application with Mapbox, which use the FusedLocationProviderApi, but I also have another component that requires listening to location updates (using the LOST API). If my other component sends a request for location updates, the Mapbox component will not receive any more location updates because there is only one LocationListener in FusedLocationProviderApiImpl (and also because the FusedLocationProviderApi is static, which seems normal).

This modification would require a bit of coding to "combine" the requests. For instance, if a request asks for a PRIORITY_HIGH_ACCURACY and another for PRIORITY_LOW_POWER, then the PRIORITY_HIGH_ACCURACY will be the effective priority. Same for the updates intervals and displacement.

Set geofence initial trigger

Description

Add ability to set behavior for initial trigger when a new geofence is added.

GeofencingRequest.Builder setInitialTrigger (int initialTrigger)

Implement GEOFENCE_TRANSITION_DWELL and loitering delay

Description

Implement ability to set loitering delay value for GEOFENCE_TRANSITION_DWELL transition type. LocationManager.addProximityAlert(...) only supports enter and exit transitions so dwelling logic will need to reside in LOST.

Circle CI is not building fork pull requests

Why isn't Circle CI building pull requests coming from forks of this project? (for example #91)

According to the Circle CI docs fork pull requests should build just without any environment variables configured via the web UI (sonatype username/password) which is fine since these are only needed to deploy snapshots from master.

https://circleci.com/docs/fork-pr-builds/

Email has been sent to @circleci support and we are awaiting a reply.

Use real timestamps when mocking GPX locations

Currently mocking a GPX trace file replays all locations at the interval specified in the LocationRequest. Mock mode should optionally replay locations using the timestamps in the GPX file to replay them at the actual interval they were received.

Produce DWELL transition events

Javadoc

Improve Javadoc coverage for public API

Injection of an Alternative Location Provider

I have been working on a project that involves writing a geolocation tracker in Android. My client has based itself in the AP region and thus the app inevitably has to deal with Chinese phones, of which the Google Location APIs based on the Wifi hotspots/cell towers don't perform particularly well.

Thus, I am looking for a way to integrate alternative location providers from e.g. Mozilla Location Service. A crude plan to do so is to modify FusionEngine to accept other external location providers in form of a LocationProvider, probably via an API of LocationServices.FusedLocationApi.addLocationProvider() (and a pairing LocationServices.FusedLocationApi.removeLocationProvider()) that allows others to add their favourite providers.

Any suggestions/pointers?

Reformat codebase using updated Mapzen java style

2-space indent, inline annotations, etc.

Fused provider fails to attach LocationResult to intent

FusedLocationProviderApiImpl#reportLocation(Location) should attach LocationResult extra to callback intents.

How to tell if failed to start listening for location updates?

I was expecting some sort of "onConnectFailed", is there not anywhere that reports errors in retrieving location updates and/or problems with "Connect"? E.g. GPS enabled but not working correctly, not providing any coords

Unnecessarily huge method count

I have to enable multidex in my very small app just so I can include Mapbox, which includes this. Why is Guava used in something like this? It's completely unsuitable for Android development and should really be avoided at all costs.

Add PendingResult<Status> return type to methods in FusedLocationProviderApi

ActivityRecognition

Is ActivityRecognitionAPI on the radar for this project?

Implement notification responsiveness

Description

Notification responsiveness is a battery optimization feature of the play services geofencing API that is subject to change by the system. It is not exposed in LocationManager.addProximityAlert(...) so its not immediately clear how this might be implemented in the context of LOST.

Automatic deployment of snapshot builds

Add support for compass sensor

I think a nice improvement over Google Play would be to add the ability to get compass sensor direction.

Currently this requires a lot of boilerplate code and filtering code to get a usable direction from the Android sensor APIs.

It would be great if LOST implemented this into an easy to use API integrated with the existing location updates with a flag during initialisation to enable it.

Also some good heuristics about when to use GPS derived direction or compass direction would be needed. Perhaps using current speed or some other factors.

Remove unused Android support dependencies to trim size and method count

Remove appcompat and possibly support library as well.
