Android-based Tablet: Samsung Galaxy Tab
Samsung Galaxy Tab is a handy, powerful, light-weight android tablet with rich features that people find fun and useful to carry with while on the move! I hope such a tablet and others will soon be popular in Karachi and then in other cities of Pakistan as well. Tablets and smartphones will be a blessing as the corporate institutions will not have to put their personal PCs on a standby UPS thus saving time, hassle and ultimately cost.

App Inventor: A great IDE for Android
Many times when one has to work under a tight deadline and have to design petty interfaces, it becomes too tedious to write XML layouts.App Inventor is a convenient tool to design user-interface in a much lesser time span. It could be useful for novice developers who have a little or no exposure to Android development. And UI designing is not all, with App Inventor developers can incorporate Media, Animation, Social and Sensor features in their apps.
App Inventor is in it's Beta. For more information here is the official link:

Text To Speech Example In Android
I had the opportunity to incorporate Text To Speech feature in E-Book apps in Android at Salsoft Technologies for Feel Social.Here is a neat example how to use the android.speech.tts.TextToSpeech
library.
Take an Edit Text Box and a Button and run the following code and feel free to leave your comments:
package az.tts;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class TexttoSpeech extends Activity implements OnInitListener {
/** Called when the activity is first created. */
private EditText text;
private TextToSpeech tts;
private String str="";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tts = new TextToSpeech(this, this);
text = (EditText) findViewById(R.id.EditText01);
//text.setText("Press me");
str = text.getText().toString();
Button btn = (Button)findViewById(R.id.Button01);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
str = text.getText().toString();
tts.speak(str, TextToSpeech.QUEUE_FLUSH, null );
Toast.makeText(TexttoSpeech.this, text.getText().toString(), Toast.LENGTH_SHORT).show();
}
});
}
@Override
public void onInit(int status) {
// TODO Auto-generated method stub
tts.speak(str, TextToSpeech.QUEUE_FLUSH, null );
Toast.makeText(TexttoSpeech.this, text.getText().toString(), Toast.LENGTH_SHORT).show();
}
}
library.

Synerzip, a leading software product development firm, has announced a partnership with Quickoffice to develop a series of office productivity applications for Android. The company cites Android’s open platform, and appeal to both consumer and business users, as a key reason for the partnership. Hemant Elhence, Founder and CEO of Synerzip, had the following to say:
“While Synerzip has been assisting its clients for the last several years in building mobile applications on various mobile platforms including Windows Mobile, Windows CE, Android, iPhone, BlackBerry, Symbian and Palm, we believe the Quickoffice partnership will maximize our focus on mobile application development with particular emphasis on the Android platform.”
No announcement was made regarding the exact number or nature of these office applications, nor was a time frame for their release given. Continue after the break for the full presser.
DALLAS, Sept. 29 /PRNewswire/ — Synerzip, a leading dual-shore Agile software product development partner for small to midsized, typically venture funded technology companies, announced today that it has partnered with Quickoffice to build a portfolio of office productivity applications for the Android platform.
Android, the first truly open and comprehensive platform for mobile devices developed by Google and the Open Handset Alliance, is the hottest new platform for mobile application development. Unlike BlackBerry which largely appeals to corporate users and iPhone which is largely consumer focused, Android promises to appeal to both consumer and corporate users. Android operating systems will be available on a broad range of devices including, mobile phones, netbooks and tablet PCs. This broad applicability of Android OS makes it an attractive platform for building end user applications.
“While Synerzip has been assisting its clients for the last several years in building mobile applications on various mobile platforms including Windows Mobile, Windows CE, Android, iPhone, BlackBerry, Symbian and Palm, we believe the Quickoffice partnership will maximize our focus on mobile application development with particular emphasis on the Android platform,” saidHemant Elhence, Founder and CEO of Synerzip.
David Halpin, Quickoffice’s VP of Engineering noted, “The Quickoffice team has broad and deep expertise in building productivity applications on all mobile platforms. Given the strong demand for our products, last year we started looking for a software development partner who could help us significantly expand our development capacity in a capital efficient manner, without compromising quality and time to market.” David added, “We are very pleased with the caliber and quality of the Synerzip team. We found Synerzip’s expertise in Agile software development practices combined with their solid experience in the mobile/Android platform a perfect match for Quickoffice.”
Hemant observed, “The Quickoffice partnership will help us accelerate the development pace on the Android platform allowing us, through our Agile practices and offshore team, to develop new and compelling mobile applications for our clients rapidly and cost efficiently.”

Tutorial: Developing a Quiz App on Android
Recently, i had to integrate a quiz module in an e-book application.I would be glad to share my code along with the schema. Using SQLite, i have the following table definitions for my schema:
CREATE TABLE Quiz(Correct_Answer TEXT, Quiz_ID INTEGER PRIMARY KEY, Quiz_Text TEXT)
CREATE TABLE Answers(Answer TEXT, Answer_ID INTEGER PRIMARY KEY, Quiz_ID NUMERIC)
CREATE TABLE Android_Metadata("locale" TEXT DEFAULT 'en_US')
NOTE: Once created the database file is to be placed in the assets folder of the project.
In order to design the layout as shown in the picture above here is the code for main.xml:
main.xml
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
android:id="@+id/rdbGp1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_y="30dip"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
>
android:text="Save" android:id="@+id/btnSave" android:layout_width="100dip" android:layout_height="wrap_content" android:layout_x="50dip" android:layout_y="250dip">
android:layout_x="17dip"
android:layout_y="15dip"
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:text="Question"
android:layout_height="wrap_content">
android:layout_x="100dip"
android:layout_y="320dip"
android:id="@+id/tvScore"
android:layout_width="wrap_content"
android:text="Score"
android:layout_height="wrap_content">
