Data is gathered using the System Usability Scale and notes regarding time spent on tasks and the accuracy of task completion are kept, in order to measure satisfaction, efficiency, and effectiveness respectively. The findings of this study show that there is need for further studies and highlights further areas for improvement on mobile Twitter applications.

Heuristic evaluation of applications built for mobile devices has different implications than their desktop (web or OS) based counterparts. The singularities of the Android platform, due especially to the vast range of devices with different specifications of hardware, make the testing scenarios not easy to cover, and are sometimes overlooked. The present work studies the implications of doing heuristic evaluation of mobile applications that support multiple screen sizes and resolutions, and proposes an adaptation of the standard, with regards to the problems and challenges that these tasks entail. It also presents a validation of the adaptation using a realworld case study. / Tesis

The Android application is developed using Native Android on Android Studio while Visual Studio 2017 is being used for the functioning of the web application.

With the rapid development of terminal hardware, mobile users and network environments, the scale of the mobile Internet appears to be catching up with the desktop Internet. Positioning System, phone sensors and applications which are able to be used anywhere have caused the arrival and increase in usage of the smart phone, and the world has become mobile-first. Within medical fields, the smart phone is also regarded as an acceptableassistant for nurses and patients as based on the advantages of mobile Internet. It is possible for healthcare personnel to assign tasks for the patients from a different place if there is a computer connected to the Internet. In addition,the smart phones is able to act as a nurse and remind the patients to complete their tasks. Accordingly, it has become a necessity to achieve this electronic healthcare system for hospitals. The objective of this research project is to summarize the procedures of this development, and release the relevant software based on an Android platform. Additionally, a corresponding website is to be designed so that healthcare personnel are able to sign in in order to deal with the tasks. The entire system has been tested in real scenarios, at this point only by the authorbut has still not been used by other organizations. The final part of the report involves the conclusions drawn and provides suggestions for further work about the whole project.

Genom att arbeta med informationsdesign har jag i detta arbete tagit fram ett förslag på en mobilapp tänkt att användas till projektet Spaden i Eskilstuna. Spaden är ett kommunalt projekt där invånare har möjlighet att påverka småskaliga byggprojekt runtom i Eskilstuna kommun. Målet med min gestaltning är att lägga fram ett förslag på ett lättanvänt, intuitivt verktyg som medborgare kan använda sig av för att lämna synpunkter till kommunen. Den mobila plattformen i mitt förslag erbjuder en ökad insyn i Spaden-projekt i den bemärkelse att invånare kan lämna synpunkter ”ute i fält”, på den plats byggprojektet planeras. Jag har i huvudsak använt mig av textdesign för att ge exempel på hur information kan presenteras och utformas i appen. För att få mitt förslag att framstå som genomförbart var det även nödvändigt att beröra ett flertal omkringliggande områden, såsom gränssnitt, utvecklingskostnad, vissa tekniska aspekter och hur appen kan marknadsföras. Detta examensarbete skrevs i samarbete med Stadsbyggnadsförvaltningen i Eskilstuna kommun. Både kvalitativa och kvantitativa metoder har använts för att ta fram en basis till mitt designförslag.

Malware in smartphones is growing at a significant rate. There are currently more than 250 million smartphone users in the world and this number is expected to grow in coming years.  In the past few years, smartphones have evolved from simple mobile phones into sophisticated computers. This evolution has enabled smartphone users to access and browse the Internet, to receive and send emails, SMS and MMS messages and to connect devices in order to exchange information. All of these features make the smartphone a useful tool in our daily lives, but at the same time they render it more vulnerable to attacks by malicious applications.  Given that most users store sensitive information on their mobile phones, such as phone numbers, SMS messages, emails, pictures and videos, smartphones are a very appealing target for attackers and malware developers. The need to maintain security and data confidentiality on the Android platform makes the analysis of malware on this platform an urgent issue.  We have based this report on previous approaches to the dynamic analysis of application behavior, and have adapted one approach in order to detect malware on the Android platform. The detector is embedded in a framework to collect traces from a number of real users and is based on crowdsourcing. Our framework has been tested by analyzing data collected at the central server using two types of data sets: data from artificial malware created for test purposes and data from real malware found in the wild. The method used is shown to be an effective means of isolating malware and alerting users of downloaded malware, which suggests that it has great potential for helping to stop the spread of detected malware to a larger community.  This thesis project shows that it is feasible to create an Android malware detection system with satisfactory results.

On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today’s solutions. The maindifference between this and existing solutions is the use of Bluetooth technology ascommunication between the devices. The project resulted in a solution consisting of twounits; one operating unit where the camera is mounted and a remote unit for control of theoperating unit. The remote unit is managed by the filmmaker. The remote unit consist of anAndroid application on a smart and which communicates with the control unit via Bluetooth.

En e-guide är ett fenomen som kan ge mervärde för besökaren. Det innebär en övergång ifrån en mänsklig guide till en digitaliserad. Det har tidigare skapats e-guider som inte har haft de tekniska aspekterna som krävs för att kunna framföra informationen till besökaren på det sätt utvecklarna och andra inblandade har önskat. Vi har undersökt och utvärderat en av dessa eguiderför att skapa en prototyp för en e-guide över Elsborg, som är en del av Världsarvet Falun. Prototypen utgår ifrån smartphones och operativsystemet Android. Utifrån tidigare och nutida eguider och prototypen, har vi analyserat resultaten och därigenom undersökt möjligheten för att skapa en generisk arkitektur, i form av en applikation för en e-guide som ska kunna appliceras på olika sammanhang oberoende av dess innehåll. Våra efterforskningar har dock visat att det ärsvårt att skapa en så pass generaliserad mall att den direkt går att implementera utan vissa justeringar.

This study evaluates the performance difference between hybrid and native mobile applica-tions when accessing the low level API. The purpose of this study is to find out the differ-ence in performance between the different methods for developing applications due to an increasing market for platform independent applications. Several benchmarks were created to measure the performance on the following criteria, execution time, memory allocation and storage space. The benchmarks were developed with a similar behaviour to match the functionality. The Titanium benchmarks were around 8.5 times larger in storage space and used 26-28% larger heap when it came to memory than the equivalent Android benchmarks. Android generally has a lower execution time than Titanium, however there are cases such as the math library where Titanium has a lower execution time.

ZigBee home automation systems have been around for years. They include smart energy efficient wireless systems that connect devices via mesh networking. It has always been a problem to connect to these ZigBee nodes with existing technologies we use daily. The premise of this project is to provide easy access to these nodes via near field communication, which is a technology that is available on a majority of smart phones today. The report details the design and implementation of N2Z, a device that translates data provided by an Android app through a NFC interface to a ZigBee device and vice- versa. We first discuss the requirements and use cases for the device and application. Then the report goes on to discuss the base technologies behind N2Z, which include the Android platform, Near Field Communication (NFC) & the ZigBee platform. The report then goes on to discuss the design and implementation of the system. Consequently, we discuss the final results of the system with certain use cases and provide some empirical data that gives us insight into system operation. Next we discuss other existing technologies that exist in the market. Finally we conclude the report with a discussion on future work and thoughts on the future of ZigBee. / text
