Working Principle of J2ME Applications with GPS Module

J2ME applications are embedded on mobile devices can utilize existing technology to him. J2ME can use GPRS technology to build an Internet-based applications. Applications on a user (mobile users) can also be enriched with animated graphics, animated interesting by offering ever-increasing user interaction.
Applications built using the J2ME profile MIDP (Mobile Information Device Profile) is known by the name of the MIDlet. MIDP is specifically used on the handset itself with the CPU, memory, keyboard and the screen is limited eg mobile phones, PDAs and so forth. GPS module for tracking devices can be connected with J2ME-based applications, it is necessary configuration. General configuration is as follows.




J2ME-based applications access the GPS receiver built-in. Once the position information is obtained, then the data is transmitted periodically through GPRS connection to the server with the HTTP protocol GPS Tracking.
The working principle own J2ME applications we simplify as follows:

1. Initialization data.
2. Read data from GPS and wait until the GPS position data has been obtained.
3. If the GPS data has been obtained and the data transmission period (eg every 1 minute) has been reached then open the GPRS connection and send data over HTTP to format the URL as above.
4. Repeat step 2, and so on, this process is performed once every 1 second.
5. Implementation of the above will be looping with timer facilities that already exist in J2ME.
