Transcript A practical approach to Mobile Programming techniques by

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++
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 )
Target Device : N 900 (Maemo)
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
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
Demo
vi pro.sh
ls -l
pwd
date
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
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”
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: gcc OpenMP (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.
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 #mkdir cprog
 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.
Demo
#include "stdio.h"
main()
{
printf("mobile c programming lab Mek \n");
}
C++ programming
Similar use the instructions for programming C++ with
new libraries as given in the paper.
Try other programming: JAVA etc

 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
