The document provides information about a talk on Google Maps Mobile. It includes: - An introduction to location-based mobile apps and trends in social and local mobile usage. - An overview of sensors and location services on Android devices that enable location-based apps. - Details on the Google Maps API and how it can be used to add maps, markers, overlays and indoor maps to mobile apps. - Examples of location-based mobile apps like My Tracks, Field Trip and Ingress that utilize the Google Maps API. - Resources for developing location-based apps using Google Maps.

6. Stats 1/2
• A new report from Juniper Research finds that
the continuing increase in smartphone
adoption and the rise of geosocial networking
will push the number of mobile social media
users from 650 million this year to 1.3 billion
by 2016; more than the total number of social
media users on all platforms today.

7. Stats 2/2
• A new study conducted by the Pew Internet &
American Life Project found that:
– Smartphone adoption has grown from 35% in 2011 to
46% in 2012, bringing with it more access to locationbased apps and services.
– about 74% of smartphone users use location-based
services to find out information about what’s around
them.
– In addition, one in five (18%) are checking in to local
businesses — from restaurants to movie theaters —
with geo-social services such as Foursquare, up from
12% in 2011.

Description
Measures the acceleration force in m/s2 that is applied
to a device on all three physical axes (x, y, and z),
including the force of gravity.
Measures the ambient room temperature in degrees
Celsius (°C). See note below.
Common Uses
Motion detection (shake,
tilt, etc.).
Measures the force of gravity in m/s2 that is applied to a
device on all three physical axes (x, y, z).
Measures a device's rate of rotation in rad/s around each
of the three physical axes (x, y, and z).
Measures the ambient light level (illumination) in lx.

three physical axes (x, y, z). As of API level 3 you can obtain
the inclination matrix and rotation matrix for a device by
using the gravity sensor and the geomagnetic field sensor in
conjunction with the getRotationMatrix() method.
TYPE_PRES Hardware Measures the ambient air pressure in hPa or mbar.
SURE
TYPE_PRO Hardware Measures the proximity of an object in cm relative to the view

24. Google Maps API Webservices
• Places API: Find detailed information (including photos) about more
than 100 million businesses and points of interest across a wide
range of categories (restaurants, parks, hospitals, ...)
• Directions API: Search for transit, driving, walking or cycling
directions using text strings (e.g. "Chicago, IL") or latitude/longitude
coordinates for origins, destinations, and waypoints
• Elevation API: Query locations on the Earth for elevation data. You
may request sampled elevation data along paths, allowing you to
calculate elevation changes along routes
• Geocoding, Static Imagery, Distance Matrix, Timezone

26. My Tracks
My Tracks registra il
percorso, la velocità, la
distanza e il dislivello
mentre cammini, corri, vai in
bicicletta o fai qualsiasi altra
cosa all'aperto. Durante la
registrazione, puoi
visualizzare i dati in tempo
reale, annotare il percorso e
ascoltare annunci vocali a
intervalli regolari sui dati
che vengono registrati.

27. Field Trip
Field Trip è la tua guida per
scoprire posti interessanti,
nascosti e unici nei dintorni.
Field Trip viene eseguito in
background sul telefono.
Quando ti avvicini a qualcosa
di interessante, l'app apre una
scheda con i dettagli sul luogo.
Non è necessario fare clic. Se
hai gli auricolari o sei connesso
tramite Bluetooth, l'app può
persino leggerti le
informazioni.
27

28. Ingress
Ingress trasforma il mondo
reale nel paesaggio di un gioco
globale fatto di mistero,
intrighi e rivalità. Spostati nel
mondo reale utilizzando il tuo
dispositivo Android e l'app
Ingress. Acquisisci oggetti utili
per la tua ricerca, distribuisci
tecnologia per conquistare
territori e alleati con altri
giocatori per portare avanti la
causa degli Illuminati o della
Resistenza.
