18. Android Architecture

22. • Includes a set of C/C++ libraries.
• Interface through Java.
• Surface manager – Handling UI Windows.
• 2D and 3D graphics.
• Media codes, SQLite, Browser engine.

24. • Android relies on Linux version 2.6 for core system services such as device
drivers, security, memory management ,process management.
• The kernel also acts as an abstraction layer between the hardware and the
rest of the software stack.

25. Compilation in Android

26. Android Execution process

27. Imp. Tools in Android
 ADT : Android Devlopment Tool used for Eclipse plugins
 Two debuggers
 adb - Android debug bridge
 ddms – Dalvik Debug Monitor Service
 aapt – Android applications packaging tools
 dx – java byte code to Dalvik executable translator

29. Android Installation Process

31. Android Application Components

33. Components - Activity
 An activity is usually a single screen:
 Implemented as a single class extending
Activity.
 Displays user interface controls (views).
 An application typically consists of several
screens:
 Each screen is implemented by one activity.
 Moving to the next screen means starting a
new activity.

34. Activity lifecycle

35. Welcome project

37. Android widgets

38. AutoCompleteTextView
• AutocompleteTextView is an editable
text view that shows completion
suggestions automatically while the
user is typing.

39. Spinner
• Touching the spinner displays a
dropdown menu with all other
available values, from which the user
can select a new one.

40. A Toast is a pop-up message, which allows you to quickly notify the user of
some event.
Toast Messages

42. The first parameter is used to set the gravity itself. Second and third
parameters define by how many pixels, relative to the value set in the
first parameter.

44. Intent in Android

45. Intents
 Intents are messages that are sent
among major building blocks.
 They trigger an activity to start
up, a service to start or stop, or
are simply broadcasts.

47. Explicit Intent
 Explicit intent is used to invoke the activity or perform the action
within the applications.
Implicit intent
 Implicit intent is used to invoke the actvity of another applications.
This type of intent is created by specifying actions.

48. Android layouts

49. User Interface
Two Ways to Create User Interface
 There are two ways to create user interface (UI) in Android. One is
declarative and the other one is programmatic. They are quite different
but often used together to get the job done.
 Declarative User Interface
 Programmatic User Interface

50. Views and Layouts
Android organizes its UI elements into layouts and views. Everything you
see, such as a button, label, or text box, is a view.

51. LinearLayout
In a linear layout, like the name suggests, all the elements are displayed in
a linear fashion, either Horizontally or Vertically and this behavior is set
in android:orientation which is an attribute of the node LinearLayout.

52. TableLayout
TableLayout lays out its children
in a table. TableLayout consists of
only other TableRow widgets.
TableRow represents a row in a
table and can contain other UI
widgets. TableRow widgets are
laid out next to each other
horizontally.

53. RelativeLayout
RelativeLayout lays out its
children relative to each other.
As such, it is very powerful as it
doesn’t require you to nest
unnecessary layouts in order to
achieve certain look.

57. Working With Sensors

58. • A Sensor is a converter that measures physical quantity and convert it into a
signal which can be read by any Observer and by any Instruments
• A Sensor is a device which receive and responds to signal when touched
What is Sensor

59. Sensor supported By Android
• Accelerometer Sensor
• Gravity Sensor
• Magnetic Field Sensor
• Pressure Sensor
• Proximity Sensor
• Temperature Sensor
• Orientation Sensor

60. Accelerometer Sensor
• Accelerometer Sensor is a Hardware Device that measures the
acceleration of the device in x , y & z Directions.

61. • Android supports all sensors via the SensorManager like as Accelerometer.
You can access SensorManager via getSystemServices
• The Sensor class Defines several constants for accessing the different
sensors:
Sensor.TYPE_GYROSCOPE
Sensor.TYPE_MAGNETIC_FIELD
Sensor.TYPE_ORIENTATION
Sensor.TYPE_ACCELROMETER

62. You can access the sensor via the sensormanager.getDefaultSenosr() method,
which takes as parameter as Sensor type
sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
Once you acquired a sensor, you can register a SensorEventListner object on it.
This listner will get informed, if the sensor data changes
sensorManager.registerListener();

Working With Location Based App

64. Obtaining user location or developing location aware application for Android
you can utilize :-
GPS – Global Positioning System
NPS – Network Positioning System
Obtaining user location

65. GPS
GPS is a technical marvel made possible
by a group of satellites in earth orbit that
transmit precise signals, allowing GPS
receivers to calculate and display
accurate location, speed, and time
information to the user

66. NPS provider determine location using shell tower and wi-fi signals. It
responds faster and consume less battery power.
NPS

67. Android Location API
LocationManager
LocationManager class provide access to the Android Location Service. The
Service allows you to access location providers,
to register location updates listeners.
LocationProvider
The LocationProvider class is the super class of different location providers
which delivers the information about the current location. This information is
stored in the Location Class

68. Location
Location class represents a Geographic location at a particular time, which is
measured by or represented by Latitude and Longitude
Latitude measures North - South position
Longitude measures West-East position
LocationListener
The LocationListener class used for receiving notification from
LocationManager when the location has been changed
