This thesis covers topic of mobile application development for Android and iOS. It also points out differences between Android and iOS programming. The main goal is to de-scribe the whole process of development which starts by choosing suitable mobile plat-forms and ends by distribution of finished application. The theory is shown on video streaming application. The first part of this thesis covers choosing of suitable platforms for development. Next chapter focuses on different development methods of mobile applica-tions. The rest of thesis is dedicated to Android and iOS development. There is one chapter covering software development kit and one chapter covering mobile user interface - its principles and creation methods. The last theoretical chapter covers fundamentals of each Android and iOS application. The whole development process of sample application is described in the seventh chapter. It includes functional and non-functional application re-quirements, analysis, design of user interface, implementation, testing and distribution of finished application. This thesis is supposed to be jump start for all new developers, who consider mobile application development.

Today, mobile devices such as smart phones and tablets have become ubiquitous and are used everywhere. Millions of software applications can be purchased and installed on these devices, customizing them to personal interests and needs. However, the frequent use of mobile devices has let a new problem become omnipresent: their limited operation time, due to their limited energy capacities. Although energy consumption can be considered as being a hardware problem, the amount of energy required by today’s mobile devices highly depends on their current workloads, being highly influenced by the software running on them. Thus, although only hardware modules are consuming energy, operating systems, middleware services, and mobile applications highly influence the energy consumption of mobile devices, depending on how efficient they use and control hardware modules. Nevertheless, most of today’s mobile applications totally ignore their influence on the devices’ energy consumption, leading to energy wastes, shorter operation times, and thus, frustrated application users. A major reason for this energy-unawareness is the lack for appropriate tooling for the development of energy-aware mobile applications. As many mobile applications are today behaving energy-unaware and various mobile applications providing similar services exist, mobile application users aim to optimize their devices by installing applications being known as energy-saving or energy-aware; meaning that they consume less energy while providing the same services as their competitors. However, scarce information on the applications’ energy usage is available and, thus, users are forced to install and try many applications manually, before finding the applications fulfilling their personal functional, non-functional, and energy requirements. This thesis addresses the lack of tooling for the development of energy-aware mobile applications and the lack of comparability of mobile applications in terms of energy-awareness with the following two contributions: First, it proposes JouleUnit, an energy profiling and testing framework using unit-tests for the execution of application workloads while profiling their energy consumption in parallel. By extending a well-known testing concept and providing tooling integrated into the development environment Eclipse, JouleUnit requires a low learning curve for the integration into existing development and testing processes. Second, for the comparability of mobile applications in terms of energy efficiency, this thesis proposes an energy benchmarking and labeling service. Mobile applications belonging to the same usage domain are energy-profiled while executing a usage-domain specific benchmark in parallel. Thus, their energy consumption for specific use cases can be evaluated and compared afterwards. To abstract and summarize the profiling results, energy labels are derived that summarize the applications’ energy consumption over all evaluated use cases as a simple energy grade, ranging from A to G. Besides, users can decide how to weigh specific use cases for the computation of energy grades, as it is likely that different users use the same applications differently. The energy labeling service has been implemented for Android applications and evaluated for three different usage domains (being web browsers, email clients, and live wallpapers), showing that different mobile applications indeed differ in their energy consumption for the same services and, thus, their comparison is both possible and sensible. To the best of my knowledge, this is the first approach providing mobile application users comparable energy consumption information on mobile applications without installing and testing them on their own mobile devices.

This master’s thesis explores ways to uncover and exploit vulnerabilities in Android applications by introducing a novel approach to security testing. The research question focuses on discovering an effective method for detecting vulnerabilities related to the context of an application. The study begins by reviewing recent papers on Android security flaws affecting application in order to guide our tool creation. Thus, we are able to introduce three Domain Specific Languages (DSLs) for Model-Based Security Testing (MBST): Context Definition Language (CDL), Context-Driven Modelling Language (CDML), and Vulnerability Pattern (VPat). These languages provide a fresh perspective on evaluating the security of Android apps by accounting for the dynamic context that is present on smartphones and can greatly impact user security. The result of this work is the development of VPatChecker[1], a tool that detects vulnerabilities and creates abstract exploits by integrating an application model, a context model, and a set of vulnerability patterns. This set of vulnerability patterns can be defined to represent a wide array of vulnerabilities, allowing the tool to be indefinitely updated with each new CVE. The tool was evaluated on the GHERA benchmark, showing that at least 38% (out of a total of 60) of the vulnerabilities in the benchmark can be modelled and detected. The research underscores the importance of considering context in Android security testing and presents a viable and extendable solution for identifying vulnerabilities through MBST and DSLs. / Detta examensarbete utforskar vägar för att hitta och utnyttja sårbarheter i Android-appar genom att introducera ett nytt sätt att utföra säkerhetstestning. Forskningsfrågan fokuserar på att upptäcka en effektiv metod för att detektera sårbarheter som kan härledas till kontexten för en app. Arbetet inleds med en översikt av nyliga forskningspublikationer om säkerhetsbrister som påverkar Android-appar, vilka vägleder utvecklingen av ett verktyg. Vi introducerar tre domänspecifika språk (DSL) för modellbaserad testning (MBST): CDL, CDML och VPat. Dessa språk ger ett nytt perspektiv på säkerheten för Android-appar genom att ta hänsyn till den dynamiska kontext som finns på smarta mobiltelefoner och som kan starkt påverka användarsäkerheten. Resultatet av arbetet är utveckling av VPatChecker[1], ett verktyg som upptäcker sårbarheter och skapar abstrakta sätt att utnyttja dem i en programmodell, en kontextmodell, och en mängd av sårbarhetsmönster. Denna sårbarhetsmönstermängd kan defineras så att den representerar ett brett spektrum av sårbarheter, vilket möjliggör för verktyger att uppdateras med varje ny CVE.Verktyget utvärderades på datamängden GHERA, vilket visade att 38% (av totalt 60) av alla sårbarheter kunde modelleras och upptäckas. Arbetet understryker vikten av att ta hänsyn till kontext i säkerhetstestning av Android-appar och presenterar en praktisk och utdragbar lösning för att hitta sårbarheter genom MBST and DSLs. / Ce mémoire de maîtrise explore les moyens de découvrir et d’exploiter les vulnérabilités des applications Android en introduisant une nouvelle approche des tests de sécurité. La question de recherche se concentre sur la découverte d’une méthode efficace pour détecter les vulnérabilités liées au contexte d’une application. L’étude commence par l’examen de documents récents sur les failles de sécurité des applications Android afin de guider la création de notre outil. Nous sommes ainsi en mesure d’introduire trois Langages dédié (DSL) pour des Tests de Sécurité Basés sur les Modèles (MBST) : Langage de Définition de Contexte (CDL), Langage de Modélisation Déterminée par le Contexte (CDML) et Motif de Vulnérabilité (VPat). Ces langages offrent une nouvelle perspective sur l’évaluation de la sécurité des applications Android en tenant compte du contexte dynamique présent sur les smartphones et qui peut avoir un impact important sur la sécurité de l’utilisateur. Le résultat de ce travail est le développement de VPatChecker[1], un outil qui détecte les vulnérabilités et crée des exploits abstraits en intégrant un modèle d’application, un modèle de contexte et un ensemble de modèles de vulnérabilité. Cet ensemble de modèles de vulnérabilité peut être défini pour représenter un large éventail de vulnérabilités, ce qui permet à l’outil d’être indéfiniment mis à jour avec chaque nouveau CVE. L’outil a été testé sur le benchmark GHERA[2] et montre qu’un total d’au moins 38% (sur un total de 60) des vulnérabilités peut être modélisé et détecté. La recherche souligne l’importance de prendre en compte le contexte dans les tests de sécurité Android et présente une solution viable et extensible pour identifier les vulnérabilités par le biais de MBST et DSLs.
