  • Location Location and maps-based apps offer a compelling experience on mobile devices. You can build these capabilities into your app using the classes of the android.location package and the Google Maps Android API. Features for Location API 1. Location Services 2. Google Maps Android API
  • Location Services Android gives your applications access to the location services supported by the device through classes in the android.location package. The central component of the location framework is the LocationManager system service, which provides APIs to determine location and bearing of the underlying device (if available). As with other system services, you do not instantiate a LocationManager directly. Rather, you request an instance from the system calling getSystemService(Context.LOCATION_SERVICE). The method returns a handle to a new LocationManager instance. Once your application has a LocationManager your application is able to do three things: Query for the list of all LocationProvider for the last known user location. Register/unregister for periodic updates of the user's current location from a location provider (specified either by criteria or name). Register/unregister for a given Intent to be fired if the device comes within a given proximity (specified by radius in meters) of a given lat/long.
  • Google Maps Android API With the Google Maps Android API we can add maps to our app that are based on Google Maps data. The API automatically handles access to Google Maps servers, data downloading, map display, and touch gestures on the map. We can also use API calls to add markers, polygons and overlays, and to change the user's view of a particular map area. The key class in the Google Maps Android API is MapView. A MapView displays a map with data obtained from the Google Maps service. The Google Maps Android APIs are not included in the Android platform, but are available on any device with the Google Play Store running Android 2.2 or higher, through Google Play services. To integrate Google Maps into our app, you need to install the Google Play services libraries for our Android SDK.
  • Sensors Most Android-powered devices have built-in sensors that measure motion, orientation, and various environmental conditions. These sensors are capable of providing raw data with high precision and accuracy, and are useful if we want to monitor three-dimensional device movement or positioning, or we want to monitor changes in the ambient environment near a device. The Android platform supports three broad categories of sensors: Motion sensors Environmental sensors Position sensors
  • Sensor Framework We can access these sensors and acquire raw sensor data by using the Android sensor framework. The sensor framework is part of the android.hardware package and includes the following classes and interfaces: SensorManager : We can use this class to create an instance of the sensor service. This class provides various methods for accessing and listing sensors, registering and unregistering sensor event listeners, and acquiring orientation information. Sensor : We can use this class to create an instance of a specific sensor. This class provides various methods that let you determine a sensor's capabilities. SensorEvent : The system uses this class to create a sensor event object, which provides information about a sensor event. A sensor event object includes the following information: the raw sensor data, the type of sensor that generated the event, the accuracy of the data, and the timestamp for the event. SensorEventListener : We can use this interface to create two callback methods that receive notifications (sensor events) when sensor values change or when sensor accuracy changes.
  • Motion Sensors The Android platform provides several sensors that let you monitor the motion of a device. Two of these sensors are always hardware-based (the accelerometer and gyroscope), and three of these sensors can be either hardware-based or software-based (the gravity, linear acceleration, and rotation vector sensors).
  • Position Sensors The Android platform provides two sensors that let you determine the position of a device: the geomagnetic field sensor and the orientation sensor. The Android platform also provides a sensor that lets you determine how close the face of a device is to an object (known as the proximity sensor). The geomagnetic field sensor and the proximity sensor are hardware-based. Most handset and tablet manufacturers include a geomagnetic field sensor. Likewise, handset manufacturers usually include a proximity sensor to determine when a handset is being held close to a user's face (for example, during a phone call). The orientation sensor is software-based and derives its data from the accelerometer and the geomagnetic field sensor.
  • Environment Sensors The Android platform provides four sensors that let you monitor various environmental properties. 1.Ambient humidity, 2.illuminance, 3.Ambient pressure 4.Ambient temperature near an Android-powered device. All four environment sensors are hardware-based and are available only if a device manufacturer has built them into a device.
