Toast - Special Feature in Android

Hi Guys already we have seen a little introduction about Android.Lets move to some of the features provided by Android. Firstly we are going to see about a concept of feedback or notification alike mechanism Toast.

A Toast provides simple feedback about an operation in a small popup. It only fills the amount of space required for the message and the current activity remains visible and interactive. For example, After sending a message it shows message send . Toasts automatically disappear after a timeout.

General procedure  to create a toast,

First, instantiate a Toast object with one of the makeText() methods. This method takes three parameters: the application Context, your message, and the duration for the toast. It returns a properly  Toast object. You can display it by toast followed by show(),as shown in the following example:


Context context = getApplicationContext(); CharSequence text = "Innov Techs"; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show();  

you may also write it as,

//Show alert for short period of time Toast.makeText(getApplicationContext(), "Innov Techs", Toast.LENGTH_SHORT).show(); //Show alert for long period of time Toast.makeText(getApplicationContext(), "Innov Techs", Toast.LENGTH_LONG).show(); 

 In our next post we can see about how to create a custom toast alert etc.

Android - A Wizard of Mobile OS

What is Android  ?

Operating Systems have developed a lot in last 15 years. Starting from black and white phones to recent smart phones or mini computers, mobile OS has come far away. Especially for smart phones, Mobile OS has greatly evolved from Palm OS in 1996 to Windows pocket PC in 2000 then to Blackberry OS and Android. One of the most widely used mobile OS these days is ANDROID. Android is a software bunch comprising not only operating system but also middle ware and key applications.

Versions

 Why Many Versions ?

• To eradicate bugs
• To make improvements.

Development Kit
To develop apps for Android devices, you use a set of tools that are included in the Android SDK. Once you've downloaded and installed the SDK, you can access these tools right from your Eclipse IDE, through the ADT plugin, or from the command line. Developing with Eclipse is the preferred method because it can directly invoke the tools that you need while developing applications.
However, you may choose to develop with another IDE or a simple text editor and invoke the tools on the command line or with scripts. This is a less streamlined way to develop because you will sometimes have to call command line tools manually, but you will have access to the same number of features that you would have in Eclipse.

How to Download SDK bundle ?

Step 1 : Go to Android Developers official Website

Step 2: Click the button download the SDK bundle for windows, after agreeing the terms and conditions choose the bit order for your computer as 32 or 64 bit
