  1. A practical Approach to Mobile Programming Techniquesby  Dr. SRN Reddy, Asstt Prof, IGIT, GGSIPU, M.Reddi Prasad Reddy, Tech MahindraProf. NupurPrakash, Principal, IGIT, GGSIPU

  2. Use of Smart Phone • Communication and computing • Making calls • Sending messages • Playing music/videos • Gaming, mailing • Web browsing, • Transacting business • Social networking etc. Is it possible for programming like Python, C and C++

  3. Introduction Mobile device for programming:- • Linux commands • Vi Editor, Filters, Pipes • Shell programming • Programming languages :- Python C and C++ WAP programming Target Platform:- Nokia’s N900 (N950 )

  4. Target Device : N 900 (Maemo)

  5. vi editor session VI is used to create any source file like shell programs, python, C or C++ programs etc. $ vi [filename] Eg:- vi pro.sh vi hello.c vi examp.py

  6. Shell Programming Methodology • Shell programming on mobile is similar to the desktop Shell Program In Nokia’s N900 (Maemo) :- • Open the xterminal in Nokia N900/950 • Write a Shell Program :- Use editors like VI editor, GTKeditor etc. to write with the file name extension .sh as in linux desktop envrnt. • Run the shell script:- ./shell script name

  7. Demo vi pro.sh ls -l pwd date

  8. Filters and Pipes etc • grep “ls” pro.sh Output:- ls –l • sed ‘/ls -l/d’ pro.sh > pronew.sh // to delete the words ls –l from the file pro.sh and redirect the result into pronew.sh • cat pro.sh| sort > pro1.sh Output: date ls -l pwd

  9. Python Programming • Open the X-terminal • Type python to go to the python shell • Eg:- to print any text similar to printf in C • print “ www.mobileeducationkit.net”

  10. C Programming methodology: Download the following packages to work with gcc in the given order: • binutils_2.18.50.20070820-4+0m5_armel.deb: This package is used to assemble, link and manipulate binary and object files. • libgcc1_4.2.1-4maemo9+0m5_armel.deb: gcc support library • libgomp1_4.2.1-4maemo9+0m5_armel.deb: gccOpenMP (GOMP) support library • cpp-4.2_4.2.1-4maemo9+0m5_armel.deb: The GNU C preprocessor • gcc-4.2-base_4.2.1-4maemo9+0m5_armel.deb:This package contains files common to all languages and libraries contained in the GNU Compiler Collection (gcc). • gcc-4.2_4.2.1-4maemo9+0m5_armel.deb:This package is the GNU C compiler, a fairly portable optimizing compiler for C.

  11. C Programming methodology cont- • Browse the directory where these packages are stored. • #/home/user/MyDocs/gcc • De-packaging all the above downloaded packages • /home/user/MyDocs/gcc #dpkg – i <package name> • Go to home directory and create one new directory as /home #mkdircprog • Compile the source C program • /home/cprog # gcc-4.2 hello.c –o out • View the out put by runing the exe file • # ./out Note:-you will get the output on the terminal screen.

  12. Demo #include "stdio.h" main() { printf("mobile c programming lab Mek \n"); }

  13. C++ programming Similar use the instructions for programming C++ with new libraries as given in the paper. Try other programming: JAVA etc

  14. www.mobileeducationkit.net (Mek) • Our Vision: "To impact quality of technical education by bridging the gap between theory and practice in teaching/learning of various ICT subjects using the ubiquitous mobile devices as the new pedagogical platform. “ • Our Mission: "Develop a practical teaching and learning environment that provides comprehensive set of guides and experiments, catering to the needs of Computer Science, Electronics and Information & Telecommunication technologies, by making use of modern computing platforms and make it freely accessible through: Mek ” Sponsored by Nokia
