  • Android mobile platform copy the class files of all applications installed in android platform and keep them into one directory. But to add the service library into a platform, Android must generate a new binary image of platform and replace the platform because android refer the libraries using the memory-mapped file method in a directory. And this memory-mapped file reference method waste the storage space of mobile device because that directory include the duplicated libraries if the libraries refered by application are duplicated, Therefore a dynamic reconfiguration method on android mobile platform is needed to manage the service libraries of application executed on android platform and support the version management and function addition/modification. In this paper, we propose the platform dynamic reconfiguration method to add dynmically the service libraries on android platform.

  • In mobile market which has been developed drastically, short distance mobile Near Field Communication is becoming the conversation topic. Google adopted this NFC technology to Android 플랫폼 for securing the leadership and many another countries including domestic companies are putting spurs to develop service and technology by connecting mobile carrier and the financial. Within this circumstance, most noticeable issue is securing stability of nfc application service. Android 플랫폼 is operating system of mobile device and also a software stack which is required limited hardware and immediate response. However, since its structural characteristic which is suitable for limited hardware, the response is not quite stable for real time process. That is, this paper researches by analyzing real time response of NFC related library provided from Android 플랫폼 and applying the result to NFC application for securing stable data process and response.

  • Since Korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented an automatic mobile contents translating system that automatically translates mobile C game contents of the GNEX platform to mobile java contents of the Android platform as a smart platform using a source-level contents translator. The GNEX C-to-Android Java automatic contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating a platform-specific-content to run under other platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

  • As the new variation malicious codes of android platform are drastically increasing, the preparation plan and response is needed. We proposed a high-interaction client honeypot that applied to the android platform. We designed flow for the system. Application plan and the function was analyze. Each detail module was optimized in the Android platform. The system is equipped with the advantage of the high-interaction client honeypot of PC environment. Because the management and storage server was separated it is more flexible and expanded.

  • In this paper, GRS chip driven JNI code application SW design based on Android platform was designed and fabricated as motion gesture frame module based on Android platform. The serial data reception module design proposed by the application-based network support API technology was designed with Android-based module design, Android-based module implementation, and Android-based function module implementation design. The data information of the sensor could be checked through Android applications such as classes of serial communication drivers, libraries, and frameworks for receiving data from wireless communication devices through Android OS applications. In addition, applications in Android implement application SW that can judge motion gestures in four directions using Java.

  • Android platform is a powerful operating system developed on Linux 2.6 Kernel, and provides many features such as comprehensive libraries, a multimedia environment, and powerful interface for phone applications. Since Android is an open operating system, which can be installed in any vendors's equipments. Current smartphones as well as netbooks, navigations, car PCs, tablet PCs, Industrial PCs are used in various fields. It is difficult a lot that to mount to other devices on the Android platform or new devices. In this Paper, The process that data that occurred from a hardware was passed to the highest application and Android platform system for managing hardware devices were analyzed. Building Android & driver compilation environment, How to support the protocol for the use of WiFi in the kernel, How to Mount a WiFi device in the kernel, Device driver registration for the Android platform, WiFi Management Service Daemon (wpa_supplicant) and IP allocation services daemon (dhcpcd) registration, How to create a socket for communication between the daemon (wpa_supplicant) and HAL have been presented. In the experiment using the proposed method, WiFi devices were mounted on the Android platform in the X-86 & ARM family. Understanding the whole process of control flow in Android hierarchy is very important to porting a new device on it. The process included in this paper can help technicians who might encounter the obstacles in their porting works.
