Almost all the mobile phone users already moved or are now moving away to smartphones for their various applications like games. If we are to speak about game applications, due to the performance limits of smartphones, 2D games are predominant over 3D games in every app. store. In this paper, we implement a 3D cube game application by porting an existing visual c++ irrlicht cube application to android platform library using the android Native Development Kit. After the porting is done, we add a few new features for more fun. Because the android NDK makes the existing C/C++ codes run directly on the android operating systems, we found by real execution tests that our 3D cube app. is well executed on a low-end android smartphone without any performance problem.

Many game and financial apps have emulator detection functionality to defend against dynamic reverse engineering attacks. However, existing Android emulator detection methods have limitations in detecting the latest mobile game emulators that are similar to actual devices. Therefore, in this paper, we propose a method to effectively detect Android emulators for mobile games based on Houdini module and strings of a library. The proposed method detects the two emulators, Nox and LD Player through specific strings included in libc.so of bionic, and an analysis of the system call execution process and memory mapping associated with the Houdini module.

Repackaging of mobile games is serious problem in the Android environment. In this paper, we propose a repackaging detection technique using shortened instruction sequence. By using shortened instruction sequence, the proposed technique can be applicable to a mobile device and can block repackaged apps coming from various sources. In the experiment, our technique showed high accuracy of repackaging detection.

The growth speed of the industry of national smart phone game service has become faster and the its economical and cultural effect has increased steadily these days. The DB design for data perpetuation in C/S MMO which has accumulated data a lot and many simultaneous plays like smart phone games is very important. This paper, mindful of the operation and the scalability suitable for android OS, by utilizing RDBMS, enabling very short, many transactions, their complexity, and a large amount of game data process, suggests fully-qualified MMORPG game service architecture design techniques widely available for more than online game industries.

모바일게임이 발전하면서 여러 디스플레이 제품과 유동적 연결이 가능하게 되었고 이를 통한 쾌적한 게임 환경이 가능하게 되었으나, 여전히 게임의 컨트롤러가 게임 진행 화면을 가려 몰입감이 떨어진다. 그렇기 때문에 Unity 3D 엔진을 이용한 First-person Shooter 게임 제작과 게임 컨트롤을 위한 Android Device Controller를 이용하여 외부 디스플레이 연결 시 컨트롤러와 게임화면이 분할되는 시스템을 개발하였다. 사용자가 모바일 디바이스를 게임 컨트롤러로 사용하여 콘솔게임 환경과 같은 편리한 조작이 가능하게 하는 효과가 있다.

In this paper, the prototyping process for developing syllable-initial consonant-based game 'Korean Guards' is described. Users may effectively learn Korean words using alphabetically sequential approaches, but the easiness of access bestowed on the smart environments and game algorithms could be fully utilized for the functional advantages for educational purposes. This functional game is developed on Android OS and the prototypical outcome is shown.

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.

The widespread use of android application is required for candidates to use in general life. Candidates need an application that doesn't change the screen a lot for the convenience and need a system that has fewer overloads. In this paper. we have implemented a program that helps students to improve their study using a note of wrong answers. vocabulary game and health management with using balanced diet, alarm, messenger, information of university and stretching.
