Develop Android app – Without Programming

 

Earlier this month, I received my invitation of App Inventor for Android from Google. This web based tool makes it easy for anyone to create Android applications without having to know how to write in a programming language. Instead of writing code, you design the application visually by solving puzzles!

According to the principle, it reminds me a WYSIWYG-editor. While registration is available only with the permission of Google. App Inventor frees you from writing code, instead you are using a kind of block designs.

Lets create an app.

For better understanding let’s look at creating application “HelloPurr”. This appendix will show the image of the cat and the button for her feeding, after clicking a cat is meowing. We will create an application from scratch, considering all the development steps presented below:

• Create a new application on the website App Inventor
• Add components as well as a label containing «Pet the Kitty»
• Add a button with a picture of a cat
• Add audio component for playback meow
• The event handler that triggers the sound when you press the button

For past few years I have been living on internet, doing a lot of stuff from the internet browser only. Sometimes, when internet goes down, I feel like my computer is almost useless and ofcourse it goes to sleep mode to get some rest!

After doing almost everything inside the internet browser, you will feel like why not have full operating system running inside it. And the answer is yes.

That means you can run this OS even on smartphone which has a native browser and keep all you file and documents in sync.

Here are few cloud operating systems that uses the power of cloud computing:
