  3. 3. INTRODUCTION • App inventor for android is an application originally provided by Google, and now maintained by the Massachusetts institute of Technology (MIT). • It allows anyone familiar with computer programming to create software applications for the Android operating system (OS). • It uses a graphical interface, very similar to Scratch and the Star Logo TNG user interface. • It allows users to drag-and-drop visual objects to create an application that can run on the Android system, which runs on many mobile devices. • Slephen Miles, a researcher at MIT and co-founder of the NFC Cluster Bostan told NFC times that about 80,000 developers. • “App Inventor is intended to make it easy for kids and beginning programmers to create their own apps ,” said Hal Abelson, Professor of Computer Science and Engineering at MIT.

  5. 5. [1-2012] The author Ankur Chandra, Shashank Jain,, “Implementation of Location awareness and sharing system based on GPS and GPRS using J2ME”, in Proceedings of 3rd International conference on Computer Research and Development (ICCRD-2012) IEEE. He suggested that GPS can show you your exact position on the Earth in any weather Conditions, anywhere in the World,24 hours a day. But he didn‟t explained how GPS transfers the messages through Web server to the mobile phones. [2-2011] The author D. Wolber, “App inventor and real world motivation”, in Proceedings of the 42nd ACM technical symposium on Computer science education. He said that the app inventor is a visual „block‟ language for creating mobile apps and it is also used for language facilitation and course focusing but he was not suggested anything about compilation of program. LITERATURE SURVEY
  6. 6. [3-2010] The author E. Spertus , M. L. chang,, “Novel approaches to CS 0 with app inventor for android”, in Proceedings of 41st ACM Technical symposium on Computer science Education. They said that the student reveal a pattern in their interactions between met cognitive processes and the domain-specific strategies used to develop a program. But they did not explained how to create a program through Java coding. [4-2010] The author Hal Abelson , “ Mobile phone apps in cs0 using app inventor for android: pre-conference workshop,” in Proceedings of the 2010 conference on Information technology education. He explained the program for GPS position locator which identifies our location through web server and transfers the message to our android phone. He also create the latitude and longitude for exact coordination. But it can not store our previous location , latitude as well longitude. Contd…

  13. 13. Program for GPS locator 1. Using the location sensor to read the current location The location sensor does some additional work for you by calling Google maps to get a street address corresponding to GPS location.
  14. 14. 2. Storing the remembered location data in a database  Tiny database store value copies the location data from the location sensor properties into the database.  As you may recall from no texting while you driving, the store value function has to arguments, the tag and the value.

  17. 17. 1. App Inventor includes an emulator for the phone. 2. The emulator lets you develop and test apps using a virtual phone instead of a real phone. 3. Instead of connecting a phone to the USB port, just start the emulator program. 4. When you click Connect to phone in the Blocks Editor, your app will appear in the emulator. Contd….Contd…
  18. 18. 1. Start the emulator and use App Inventor just as you would with a real phone. 2. Connect to the App Inventor site, start the Blocks Editor, and press Connect to Phone. 3. Your application should appear in the emulator. 4. Don’t forget to “unlock” the virtual phone after it starts up. Contd….Contd…
