The document outlines a workshop on Android application development conducted by the Department of Information Technology at Priyadarshini Bhagwati College of Engineering, detailing Android's history, application components, and XML design. Key topics include activities, services, intents, and content providers, alongside fundamental UI components like TextView and EditText. The document provides XML code examples for various layouts, demonstrating how to create user interfaces for Android applications.

2. Today's Catalog
1) Introduction about android
2) Introduction about component
3) UI Components and XML designing

3. Introduction about Android
Software platform from Google and the Open Handset Alliance
July 2005, Google acquired Android, Inc.
November 2007, Open Handset Alliance formed to develop open standards for mobile devices
October 2008, Android available as open source
December 2008, 14 new members joined Android project

4. Features of Android
Reuse and replacement of components
Integrated browser
Optimized graphics
Media support
Camera, GPS, compass, and accelerometer
Rich development environment

5. Introduction about Components
Android Application Components :
1) Activity
2) Services
3) Intents
4) Content Providers

6. Introduction about Components
Android Application Components :
1) Activity
2) Services
3) Intents
4) Content Providers

7. Android Application Components :
1) Activity
Present a visual user interface for one focused endeavor the user can undertake
Example: a list of menu items users can choose from
2) Services
Run in the background for an indefinite period of time
Example: calculate and provide the result to activities that need it

8. 3) Intents
Hold the content of a message
Example: convey a request for an activity to present an image
to the user or let the user edit some text
4) Content Providers
Store and retrieve data and make it accessible to all applications
Example: Android ships with a number of content providers for common data types
(e.g., audio, video, images, personal contact information, etc.)

9. Xml Designing and UI Components
1) XML Designing :
XML stands for eXtensible Markup Language.
XML was designed to store and transport data.
XML was designed to be both human- and machine-readable.

10. Xml Designing and UI Components
2) UI Components :
Textview
Edittext
Button
Imageview
Imagebutton
Relative Layouts
Linear Layouts

11. 1) Textview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:id="@+id/text_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="I am a TextView" />
</LinearLayout>

12. 2) EditText
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText
android:id="@+id/simpleEditText"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
</LinearLayout>

13. 3) Linear Layout
LinearLayout is a view group that
aligns all children in a single
direction, vertically or horizontally.
You can specify the layout direction
with the android:orientation
attribute.

14. <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:orientation="vertical" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/to" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/subject" />
<EditText
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="top"
android:hint="@string/message" />
<Button
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="@string/send" />
</LinearLayout>

15. 4) Relative Layout
RelativeLayout is a view group that displays
child views in relative positions. The position
of each view can be specified as relative to
sibling elements (such as to the left-of or
below another view) or in positions relative to
the parent RelativeLayout area (such as
aligned to the bottom, left or center).

16. <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk
/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp" > <EditText
android:id="@+id/name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/reminder" /> <Spinner
android:id="@+id/dates"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_below="@id/name"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="@+id/times" />
<Spinner android:id="@id/times"
android:layout_width="96dp"
android:layout_height="wrap_content"
android:layout_below="@id/name"
android:layout_alignParentRight="true" />
<Button android:layout_width="96dp"
android:layout_height="wrap_content"
android:layout_below="@id/times"
android:layout_alignParentRight="true"
android:text="@string/done" /></RelativeLayout>
