Research of Multimedia Applications based on Android Platform

Over the past few years, we can see the enormous increase of the use of smart phones that are based on android platform. Due to that reason, the mobile application development based on android has boosted the developers' interest. Having countless android application on the market is not an assurance of having users' satisfaction. Some of them do not reach users' expectations due to lack of research on dealing with android-based application requirements. With the fast growing of smart phones and their applications, the needs for better application to be produced are needed. Currently there is no specific research on analyzing the requirements for android applications. This paper proposes a new strategy that uses an activity theory to analyze the requirements of android application. It is then discusses a case study of a Muslim android application and presents the results of its requirements analysis using activity theory. The result of this study shows activity theory as an alternative requirement analysis approach to mobile application development that is based on android operating system.

In this technology world, smartphones are greatly adopted by people due to the need of personal communication, Internet and many more requirements. Users are attracted to use the android operating system due its availability for low-cost and millions of freely available applications. The popularity of android operating system is also welcomes the attackers. Statistics have shown that, the growth of android malware is becomes double by every year. Hence android platform is more vulnerable to malwares. Researchers are proposed various models. Some of these models are completely fail to detect unseen variants of malware, while remaining models are inefficient to detect new malware families. In this paper, we briefly explain about android architecture, structure of android application and also characterized android malware based on their installation, activation and payloads types. We proposed a hybrid model to detect the malware based on permission bit-vector and network traffic. We constructed a decision tree classifier to detect the android malware. Our results show that combination of permission bit-vector and network traffic analysis is highly efficient by achieved 95.56% of detection accuracy.

In software testing process, test data generation represents an important step for high quality software, even for mobile devices. As proposed in previous works, a potential source for random data generation is represented by the UI layout files that are used for almost all mobile platforms (Android, iOS, Windows Phone/Mobile). This paper continues the previous work and presents a test data generation system based on Android layout files. The test data generator uses DSL files as input and generates test data that conform to several testing principles. The generated test data could be stored in XML files or any format required by the testing frameworks.

Until now we have covered SharePoint Online features, Office 365 tools, and looked in-depth toward, creating a digital customer experience (DCX). In this chapter, we will focus on building digital portals using SharePoint Online. We will explore both the User Interface (UI) and User Experience (UX) in detail; it's important these are adopted for websites in order to generate DCX. Digital Portals are specialized websites that are smart and intelligent. A fundamental difference between a portal and a website is that a website is hosted on the Internet to drive traffic whereas a portal is developed within an organizational boundary to meet user-specific needs. An example of a website is the company’s standard website, and an example of a portal is a sales portal to meet the objective of a sales community. Also in the chapter, we will look at the modern software development life cycle (SDLC), which is getting used to building products such as the SharePoint Online Portal. Using these techniques to build intelligent portals that are eye catching, user oriented, and friendly to navigate are what give us DCX.

Nowadays, the rapid evolution in the mobile phone industry has attracted lots of consumers around the world while smartphones being the trend of the phone with the highest demand by a large margin. Recent research has shown that Android Operating System has accounted for 88% of the mobile phone market which has led to the production of different varieties malware targeted mostly on Android Phones. Furthermore, recent research has also revealed that there is high negligence to this great threat where by Android Antimalware software only counter trivial attacks posed by malware or viruses. This paper supports most of the theories and in fact, focuses on one of the most typical vulnerabilities of Android Antimalware which is the mutation attacks. In this paper, the best in class mobile antimalware for Android were assessed and tested how safe they are against different normal obfuscation strategies even with known malware and the results were not up to a satisfactory level. Furthermore, the scope of this research also spans to the implementation of a proposed antimalware which detects and counters mutation attacks using static detection of Android malware using Integrity Check Technique. The feedbacks were analyzed using SPSS 2.0. Analysis of respondents’ feedbacks shows that there is even little or no knowledge of malware threats or proper antimalware by mobile phone users. This brings great concerns and this work shows why assessment of this subject matter is and essential considering the rapid growth of smartphone usage. This paper is to evaluate the efficacy of Anti Malware tools on Android in the face of various evasion techniques while developing a system that counters this evasion technique.

In this chapter, various aspects pertaining to the open operating system Android OS such as its history, architecture, features, and utility for business purposes will be introduced, following which the role of Android in enterprise management will be explained. The chapter will be concluded by a detailed report of the BYOD approach that uses Android for industrial control and automation. Since mobile devices have become progressively more powerful and accessible, mobile computing has greatly changed our daily lives. As one of the most popular mobile operating systems, Android provides the tools and API for Android developers to develop Android applications. Android is an open source operating system for mobile devices. Today its primary use is lodged in the mobile phone industry. During the recent past years, many projects have been created, with the objective to elevate Android to other platforms, such as sub-notebooks or embedded systems.

In this paper, a design and an implementation on an intelligent guide system based on Android platform is proposed. The hardware of system is based on ARM platform, and the schematics of its main modules such as power, SDRAM are given. Then Android operation system is transplanted on the ARM platform. On this basis, the application software is developed using Eclipse and Android SDK, and it is consisted of three modules: multimedia application, web maps and recording. The module of multimedia application includes audio, picture and video. Web maps can display Google Maps on the device and achieve positioning. The record module has implemented the several normal operation on a record, such as creating, modifying and displaying.

Responsiveness is an important type of quality factor in Android application because it directly affects user experience. When the user interface thread performs lengthy operations, the user may feel that the application has become sluggish or frozen. This may lead to a negative user experience, poor review, and loss in market success. This paper proposes a static responsiveness analysis tool for Android applications to find potentially poor responsiveness defects which are difficult to detect by conventional testing methods as they are sensitive to the user environment. This tool finds responsiveness defects by discovering operations invoked in the user interface thread that may block the execution of other operations. We collect these operations according to Android developer guideline and previous related work. The proposed tool successfully found 45 potential responsiveness defects in seven open source Android applications.

This paper answers two key research questions: 1) What is the relationship between product quality and service quality on customer satisfaction within an integrated model? 2) What is the relationship between customers' satisfaction and customers' intention to switch brands in the automobile industry? PLS-SEM is a tool used to assess measurement reliability and validity and to estimate the relationships among service quality, product quality, customers' satisfaction, and customers' intention to switch brands. Results show that service quality does not significantly determine customer satisfaction. Instead, product quality significantly influences customer satisfaction. The findings contrast a prior Quality Management Journal study conducted in the mobile phone industry that found that provider service quality is relatively more important than product quality. The results also show that customer satisfaction has a negative effect on customers' intention to switch brands. This research contributes to the ongoing debate surrounding service-dominant (S-D) logic and goods-dominant (G-D) logic of exchanges by empirically supporting the G-D logic in the context of the automobile industry. The study suggests future modification to the traditional quality-satisfaction model based on the type of product.

As smart phones are becoming widespread over the world, relevant security problems emerge. On Android platform, some applications are granted to access some restrictive resources via system APIs. Such applications may expose this capability to the other applications without certain permissions. This will lead to permission re-delegation attacks. In this paper, we describe how this vulnerability occurs on Android through inter-process communication (IPC). We focus on a major IPC channel in Android operating system, the intent based IPC. In order to help developers decrease the possibility of their applications to be attacked, we present a static analysis tool Diordna in this paper. Diordna works on Java byte codes and finds out possible permission re-delegations from public entry points of applications. Diordna also leverages a dataflow analysis to generate intent oriented test case specifications, namely, to infer what should be contained in an intent object by which the target application will re-delegate its granted permissions. We have experimented our solution and Diordna on two pre-installed Android applications and it generates reasonable test case specifications that can be used to write testing programs.

As Android User's and its application market is growing; android applications tend to collect user's data for various purposes; for advertisement agencies, for better user experiences and to learn about user's behavior on internet. However, it raises concern about privacy of an individual being compromised. We propose a methodology to make android applications deterrent to data leakage as well as detect covert communications in them. We have used reverse engineering approaches to identify sources and sinks of the data leakage as well as covert communication, if any. We tested our methodology over a set a 57 highly popular applications from PlayStore and found that nearly 40% are covertly collecting user's data and nearly 60% are making questionable connections to undeclared servers. However, after modification of application we did not find much difference in user experiences. We also did a case study of data logging application, DroidWatch by Justin Grover.

Android platform has gained popularity in recent years in terms of its usability by common people, low cost handsets market share and number of available applications. Android operating system was built on a modified Linux kernel with built-in common web services such as email, web browser, and map applications. This paper presents the architecture and design specifications for a Student Attendance Marker Application on an Android platform. The use of android phones for such purposes can ease them to do work quicker. Usage of mobile phones for applications like attendance marking system shows enhanced utility of Smartphones. This application intends to replace common physical register notebooks which are very commonly used in developing countries including India.

Managing privacy leakage is of great importance in the Android platform. The variety of new user-privacy fraud reveals a new challenge in predicting potential privacy disclosure threats and protecting the privacy inside our pocket. In this paper, we present an analysis framework, called AppLeak, for information loss evaluation, privacy leakage detection, and privacy risk assessment on Android applications. With newly formalized privacy measures, AppLeak can effectively and efficiently support mobile user in identifying privacy risks of specific mobile applications.
