As the more people use smart phones, the interest in the apps gets the higher. Studies such as App Inventor, app generation methods using templates provide app development process with app development methods by substituting programming work. However, the realm of producible apps is limited and there are a lot of set up operations and input informations. Also, there is lack of support for smart phone sensors that are in a high demand of utilization. This paper proposed an android app development method for resolving existing problems, and implemented an accompanying app development tool. When the proposed app development method derived through combination of function modules and sensor modules is used, it's possible to produce apps with minimal user inputs, and to use sensors easily. Also, because it is simple to identify overall flow of app execution, and functions addible to the app are provided for users by units of module, it is possible to develop apps quickly.

WebView is a vital component in smartphone platforms like Android, Windows and iOS that enables smartphone applications (apps) to embed a simple yet powerful web browser inside them. WebView not only provides the same functionalities as web browser, it, more importantly, enables a rich interaction between apps and webpages loaded inside the WebView. However, the design and the features of WebView lays path to tamper the sandbox protection mechanism implemented by browsers. As a consequence, malicious attacks can be launched either against the apps or by the apps through the exploitation of WebView APIs. This paper presents a critical attack called Supplementary Event-Listener Injection (SEI) attack which adds auxiliary event listeners, for executing malicious activities, on the HTML elements in the webpage loaded by the WebView via JavaScript Injection. This paper also proposes an automated static analysis system for analyzing WebView embedded apps to classify the kind of vulnerability possessed by them and a solution for the mitigation of the attack.

This study was designed to examine the antecedents of mobile app usage among smart phone users. An extended TAM, which included the additional factors of perceived enjoyment, perceived informative usefulness and perceived social usefulness, was applied to predict people's intention to use mobile apps. Overall, the hypothesized research model did a fairly good job explaining significant associations between the independent variables and the dependent variable. The findings had showed that perceived social usefulness, perceived enjoyment and attitude were significantly affect intention to use mobile apps. Meanwhile, perceived ease of use (PEOU) and perceived informative usefulness were not significantly effects attitude towards intention to use mobile apps. Therefore, mobile apps developers should develop mobile apps that are easier for the users to seek information. For the information available should be more precise and bringing more benefits to the users.

This study presented the need to research into 'emotional response' and 'willingness to use apps', perceived by consumers using food delivery apps amidst the spread of smartphones and surge in use of food delivery apps. This study was also intended to present 'service quality' of food delivery apps, along with 'arousal' and 'pleasure' which represented the 2 types of emotional dimension of Pleasure-Arousal-Dominance(PAD), as variables that could strengthen the willingness to use food delivery apps and examine their roles. On the basis of results of such analysis, we intended to provide basic data necessary for development and operation of food delivery app contents. For subjects and spatial scope of this study, we selected domestic male and female residents nationwide who were aged 20 or older and had experience of using food delivery apps over the last 3 months. Among the subjects of this study, we surveyed foodservice consumers who had experienced of ordering food via food delivery apps such as Baedal Minjok, Yogiyo, and Baedaltong. Based on results of this study, it was found that design and sympathy related to food delivery app service quality had a positive effect on arousal while design and reliability had a positive effect on pleasure. Both informativity and mobility of food delivery app service quality were found to have a positive effect on the willingness to use apps. The pleasure from PAD had a positive effect on willingness to use apps, while arousal did not have any effect on willingness to use apps. The results of this study suggested that design and reliability, informativity, mobility were very important factors in inducing foodservice consumers to use food delivery apps continuously.
