Android library project that intends to simplify the usage of location providers and activity recognition with a nice fluid API.

Supported Android versions: Android 2.3+

You should add this to your dependencies:

compile ('io.nlopez.smartlocation:library:3.0.2'){
	transitive = false;
}

If you are already using Google Play Services in your project, you must set the transitive property to false:

compile ('io.nlopez.smartlocation:library:3.0.2'){
	transitive = false;
}

For starting the location service:

SmartLocation.with(context).location()
    .start(new OnLocationUpdatedListener() { ... });

If you just want to get a single location (not periodic) you can just use the oneFix modifier. Example:

SmartLocation.with(context).location()
    .oneFix()
    .start(new OnLocationUpdatedListener() { ... });

For stopping the location just use the stop method.

SmartLocation.with(context).location().stop();

There are three presets for location parameters:

• LocationParams.BEST_EFFORT (default)
• LocationParams.NAVIGATION
• LocationParams.LAZY

You can change it (if you want one other than the default one) by using the config(locationParams) modifier.

If you want to add some custom parameters for the distances or times involved in the location strategy, you can create your own LocationParams class.

There are some providers shipped with the library.

• LocationGooglePlayServicesProvider (default). This will use the Fused Location Provider.
• LocationManagerProvider This is the legacy implementation that uses LocationManager.
• LocationBasedOnActivityProvider This allows you to use the activity recognition system to modify the location strategy depending on the activity changes (if the user is walking, running, on a car, a bike...).

You can implement your own if you want. That's ideal if you wanted to use a mock one for testing or something like that, or add support to another possible provider.

Example:

SmartLocation.with(context).location()
    .provider(new LocationBasedOnActivityProvider(callback))
    .start(new OnLocationUpdatedListener() { ... });

For starting the activity recognition service, you should run:

SmartLocation.with(context).activityRecognition()
    .start(new OnActivityUpdatedListener() { ... });

For stopping the activity recognition you could use the stop method.

SmartLocation.with(context).activityRecognition().stop();

This is still experimental. Please don't use this feature in production yet :)

We can add geofences and receive the information when we enter, exit or dwell in a Geofence. The geofences are defined by a GeofenceModel, and you should use the requestId as a identifier.

We can add and remove geofences with a similar syntax as all the others.

GeofenceModel mestalla = new GeofenceModel.Builder("id_mestalla")
    .setTransition(Geofence.GEOFENCE_TRANSITION_ENTER)
    .setLatitude(39.47453120000001)
    .setLongitude(-0.358065799999963)
    .setRadius(500)
    .build();

GeofenceModel cuenca = new GeofenceModel.Builder("id_cuenca")
    .setTransition(Geofence.GEOFENCE_TRANSITION_EXIT)
    .setLatitude(40.0703925)
    .setLongitude(-2.1374161999999615)
    .setRadius(2000)
    .build();

SmartLocation.with(context).geofencing()
    .add(mestalla)
    .add(cuenca)
    .remove("already_existing_geofence_id")
    .start(new OnGeofencingTransitionListener() { ... });

Forks, patches and other feedback are welcome.
