Android Tutorials
GTU (Gujarat Technological University) has introduced subject Mobile Computing using Android in 5th semester syllabus. An Android is developed by Google and now a day it becomes most popular mobile operating system because it is open source and free.  Development with Android becomes easier because it has similar syntax to java and traditional C and C++.  Android contains large set of C/C++ libraries to support various components of Android OS.

On this page you will get list of various websites which provides free android tutorials, learning materials and examples, android application downloads and many more resources. These resources will become very helpful for GTU MCA students to learn Android and make their own application in android.

Classpad Tablet Launched By Rohit Pande - Tablet War Started!

No comments


The tablet war started with the launching of Classpad Tablet by Rohit Pandae. He is a graduate from IIT (Indian Institute of technology) Delhi and CEO of Classteacher Learning System.  As we all know that the Government of India has developed Aakash Ubislate tablet for students, so the  launching of classpad becomes war between Aakash and Classpad.
Classpad Tablet V/s Akash Tablet


Classpad is more customized tablet for students as compared to Aakash Ubislate tablet. It is more personalized tablet which will provides interactive learning and teaching for students and teachers. This tablet will give the competition to Aakash in Indian tablet market.

Classpad tablet
Launching of Classpad Tablet
Classpad is Android based touch screen tablet which has seven – hour battery life, 1.3 Ghz processing speed. It has built in 4 GB Memory expandable up to 8 GB.  It is available in two versions two models Troelly which is designed for multiple-students based usage and One Tablet Per Child (OTPC).


Mr. Rohit Pande, Chief Executive of Classteacher Learning Systems, said, “Using Classpad, teachers would be able to transfer class work to the students' tablet effortlessly, share their own content and conduct tests/assessments without any hassle. Students can also attempt assessments and get immediate results and enhance their learning techniques.”
The Classpad is more costly then Aakash tablet because it provides more facility and advancement then aakash tablet. Classpad priced from Re. 7500 to 14000 which comes in three versions Classpad 7, Classpad 8 and Classpad 10 which can be used by 3 to 12 Std students.

Many competitors of Aakash tablet found golden opportunities in Indian market for tablet computers. All companies try to provide tablet with better functionality in chipper cost so at final customer and students will get benefits in this tablet war.
