CREATE LINEAR LAYOUT

Create or Update the template layout, Relative Layout to the following Code.

===>>src/main/res/layout/activity_home.xml

<LinearLayout

android:orientation="vertical"

android:layout_height="match_parent"

android:layout_width="match_parent" >

<TextView

android:layout_height="wrap_content"

android:layout_width="wrap_content" 

android:textColor="@android:color/black"

android:textSize="50sp"

android:text="@string/hello_world"/>

</LinearLayout>

CREATE ACTIVITY

Create or Update the template java Class. ==>> src/main/java/package-name/HomeActivity.java

Change ActionBarActivity to Activity for extended class for java class HomeActivity

public class HomeActivity extends ActionBarActivity {

 @Override

 protected void onCreate(Bundle savedInstanceState) {

 super.onCreate(savedInstanceState);

 setContentView(R.layout.activity_main);

 }

}

REGISTER ACTIVITY

Register your activity in manifest file.  ===>>src/main/AndroidManifest.xml

In it we define which activity is launcher activity means execute first.

<manifest package="net.uni_world.android_1110.foodscourt">

<application android:theme="@style/AppTheme" android:label="@string/app_name" android:icon="@drawable/ic_launcher"android:allowBackup="true">

<activity android:label="@string/app_name" android:name=".MainActivity">

<intent-filter>

<action android:name="android.intent.action.MAIN"/>

<category android:name="android.intent.category.LAUNCHER"/>

</intent-filter>

</activity>

</application>

</manifest>

NOTE: 

 REMIND THESE 3 MAIN POINT FOR CREATE APP.LIKE:

1.  FIRST IS CREATE LAYOUT ACTIVITY (XML)
2.  SECOND ONE IS CREATE JAVA ACTIVITY CLASS (.JAVA)
3.  THIRD ONE IS REGISTER UR ACTIVITY IN MENIFEST.XML ACTIVITY.

ANDROID APP.. DESIGNING CODES

FOR UNDERSTAND ANDROID CODE AND APP. DESIGN FIRST WE NEED TO UNDERSTAND SOFTWARE REQUIREMENT SPECIFICATION (SRS).

The Key Steps….

Understand the SRS (Software Requirement Specification) of client.Then plan how to facilitate the client requirement in the app.Afterwords, sketch the screen as per your understanding of project. SRS (Software Requirement Specification)It is a complete document which includes……

● The Company Portfolio

● The requirement

● All the related detail to describe about & for project.

Sketching & Wireframing

• Wireframing, a step in design whereto start layout your screen.
• Easiest and fastest way is to sketch.
• After number of tries finalize the sketch.
• Then make the Digital Wireframing for Adobe Illustrator, Abode Fireworks, BestInMind etc.

Prototype 

Prototype sample/model to test a concept learned from. It used in design, electronics & SP.

Often client at initial stage unable to describe complete application objectives and output etc.

MYSQL DATABASE

What is MySQL?

MySQL is a database system used on the web.MySQL is a database system that runs on a server

MySQL is ideal for both small and large applications.MySQL is very fast, reliable, and easy to use

MySQL uses standard SQL.MySQL compiles on a number of platforms.MySQL is free to download and use.MySQL is developed, distributed, and supported by Oracle Corporation.MySQL is named after co-founder Monty Widenius's daughter: My

The data in a MySQL database are stored in tables. A table is a collection of related data, and it consists of columns and rows.

Databases are useful for storing information categorically. A company may have a database with the following tables:

1. Employees
2. Products
3. Customers
4. Orders

PHP + MySQL Database System

PHP combined with MySQL are cross-platform (you can develop in Windows and serve on a Unix platform).

Database Queries:

A query is a question or a request.

We can query a database for specific information and have a record set returned.

Look at the following query (using standard SQL):

Example of Query:

SELECT LastName FROM Employees.

Note:

The query above selects all the data in the "LastName" column from the "Employees" table.
