Exclusive “App Inventor” for Android Mobile

We want to become unique in our own little ways. That is why we want to do things our way even if it puts a question mark to someone’s face. As long as we enjoy it and as long as its spells out our being us, then off we go!

This is the same story as that of competing mobile phones.

Mobile technology has its own way of becoming distinctive to one another even if both have same main uses. There would always be one thing different from the other that would make us users choose what suits our taste, what goes with our preferences, and what brings out the best in us.

And I am talking about applications, the unique ones!

A great example of a mobile technology using this kind of distinctive features is the Android mobile phone.

What is Android Mobile?

Android mobile phone is an open phone platform created by the Google itself. It is named by its creator as “software stack” – a mobile phone simply made up of an operating system where everything runs; a middleware for talking to a network and to one another; and last is application which is a set of programs the phone can carry out .

Its center application includes email client, SMS program, Calendar, Maps, Browser, Contacts and other important set of programs not specified.

In order for this mobile phone to become different from those other phones, a new tool was then made – the App Inventor.

Application Inventor – “App Inventor”

One of the important factors that made Android Mobile an Android Mobile is its set of applications.

An application that consists of different programs the phone could command to. It also serves as a trademark to a certain phone because not all applications are found in different Phone makers.

In order for these Android Phones to promulgate further, a new tool is being introduced by Google to the public. A tool called “App Inventor” (Application Inventor).

It is has a “drag-and-drop interface” with an easy and hassle-free set of commands that could bring someone (with no programming background or experience) make their own applications.

Indeed, it has a very unique way of reaching its consumer by not mainly become a simple consumer but also become an application maker itself.

This somehow would help the Google Company and its Android mobile phone exceed other mobile phones like those of Apple’s iPhone or RIM’s Blackberry which requires more comprehensive programming experience.

It will also guide to zillion of applications that could convince other non-user to choose the Android mobile.

Though some of the applications may not have much of importance, it could help the inventor to become popular, and could even get or have a chance to develop his or her potentials to a career as an Android Application Inventor.

With its unique way approach, these applications which is exclusively made and be available for Android mobile phones would help all its users become unique in its own way too.

Again, a new era for Android Phones and its users!

Adobe’s PDF reader too slow for Android

The Google I/O developer conference was followed by the release of the official PDF reader for the Android mobile operating system of Google. The application has a simple and very effective feature set which allows viewing and navigating PDF files on Android devices.

The program was tested on an Evo 4G Smartphone made by HTC and powered by Android 2.1. The latest issue of Full Circle Magazine was used as a sample PDF, in order to make it possible to evaluate its performance by using relatively complex layouts. Initial load time seemed a bit longer than expected, when opening the PDF file from the download manager of the browser. Almost six seconds were necessary for the application to launch and render the document’s first page.

The user interface appears as simple and functional, although it is not consistent with the interface offered by other Android applications. Semi-transparent toolbars situated on the top and bottom of the screen fade out when not needed and give the user maximum viewing space possible during reading. Buttons for scroll and zoom are placed at the bottom toolbar, while the top toolbar displays the document title and is provided with a button allowing the user to switch the viewing mode.


Multitouch pinch-zooming as well as flick-scrolling are supported by the application, but they were a bit slow during the test due to the overhead of content redrawing. Flick-scrolling is also occasionally slow while loading and drawing more content. If flick-scrolling is too fast, only blank sheets will appear instead of content of the pages. This makes it difficult to detect where you are in the document if you try to navigate faster.

Although this lag is somehow inconvenient during navigation, the reading experience is not affected. When the content is zoomed, the application is able to provide new rendered material fast enough to make reading comfortable and does not affect the pace of scrolling.

There is an alternate display mode, in addition to the standard one, in which the text is wrapped automatically, in order to fit the width of the screen. This alternate mode breaks down any element of the layouts and provides a solid stream of text that makes panning useless.

This display mode works fine with PDFs consisting mainly of formatted text with simpler layouts, such as e-books, and does not handle PDFs with intensive graphics. When in re flow mode, the zooming buttons of the toolbar situated on the bottom of the screen are replaced with a set of buttons that can be used to increase or decrease the font size.


The application runs properly and can support the kind of touch screen interaction expected by the users of modern mobile software. However, it is not a surprise that PDF rendering speed for a Smartphone is weak. The feature set, although sufficient, is modest, the main feature that is missing that supports searching.
The Adobe Reader for Android can be found in the Android market and is working on most devices running the Android 2.1 version or later. Adobe has performed tests on popular handsets like Google’s Nexus One or Motorola’s Android.
