Android Software Platform Development at Fujitsu

Smartphones using the Android platform first appeared on the market in October 2008. They have since overtaken Apple's iPhone-the first entry in the smartphone market in number of units shipped and have helped to bring about major changes in the way that mobile phones are used. Android was developed and is distributed as open source software that a device maker integrates into its own hardware after adding original software technologies. The Android platform evolves in short cycles on the basis of software and hardware developments as the network infrastructure continues to expand in the form of WiMAX and LTE and as usage scenarios and services become increasingly diverse. Fujitsu has been developing Android smartphones with compelling functions and enhanced convenience since December 2010, when it released the REGZA Phone T-01C featuring a water-resistant enclosure, one-seg support, and FeliCa contactless IC card and infrared-communication functions. This paper describes Fujitsu's approach to smartphone development, focusing on memory management and current-consumption management as important elements in the system design of the Android software platform, diverse manner modes for enhancing user convenience, high-picture-quality technology achieved by using the Mobile REGZA Engine, and audio-visual device-linking technology based on DLNA standards.
