Google Android : a comprehensive introduction

Google Android, Google's new product and its first attempt to enter the mobile market, might have an equal impact on mobile users like Apple's hyped product, the iPhone. In this Technical report we are going to present the Google Android platform, what Android is, describe why it might be considered as a worthy rival to Apple's iPhone. We will describe parts of its internals, take a look "under the hood" while explaining components of the underlying operating system. We will show how to develop applications for this platform, which difficulties a developer might have to face, and how developers can possibly use other programming languages to develop for Android than the propagated language Java.

Android Malware Detection Using Parallel Machine Learning Classifiers

Mobile malware has continued to grow at an alarming rate despite on-going mitigation efforts. This has been much more prevalent on Android due to being an open platform that is rapidly overtaking other competing platforms in the mobile smart devices market. Recently, a new generation of Android malware families has emerged with advanced evasion capabilities which make them much more difficult to detect using conventional methods. This paper proposes and investigates a parallel machine learning based classification approach for early detection of Android malware. Using real malware samples and benign applications, a composite classification model is developed from parallel combination of heterogeneous classifiers. The empirical evaluation of the model under different combination schemes demonstrates its efficacy and potential to improve detection accuracy. More importantly, by utilizing several classifiers with diverse characteristics, their strengths can be harnessed not only for enhanced Android malware detection but also quicker white box analysis by means of the more interpretable constituent classifiers.

A New Android Malware Detection Method Using Bayesian Classification

Mobile malware has been growing in scale and complexity as smartphone usage continues to rise. Android has surpassed other mobile platforms as the most popular whilst also witnessing a dramatic increase in malware targeting the platform. A worrying trend that is emerging is the increasing sophistication of Android malware to evade detection by traditional signature-based scanners. As such, Android app marketplaces remain at risk of hosting malicious apps that could evade detection before being downloaded by unsuspecting users. Hence, in this paper we present an effective approach to alleviate this problem based on Bayesian classification models obtained from static code analysis. The models are built from a collection of code and app characteristics that provide indicators of potential malicious activities. The models are evaluated with real malware samples in the wild and results of experiments are presented to demonstrate the effectiveness of the proposed approach.

Sistema de localização de veículos para smartphone android

Atualmente os sistemas Automatic Vehicle Location (AVL) fazem parte do dia-a-dia de muitas empresas. Esta tecnologia tem evoluído significativamente ao longo da última década, tornando-se mais acessível e fácil de utilizar. Este trabalho consiste no desenvolvimento de um sistema de localização de veículos para smartphone Android. Para tal, foram desenvolvidas duas aplicações: uma aplicação de localização para smarphone Android e uma aplicação WEB de monitorização. A aplicação de localização permite a recolha de dados de localização GPS e estabelecer uma rede piconet Bluetooth, admitindo assim a comunicação simultânea com a unidade de controlo de um veículo (ECU) através de um adaptador OBDII/Bluetooth e com até sete sensores/dispositivos Bluetooth que podem ser instalados no veículo. Os dados recolhidos pela aplicação Android são enviados periodicamente (intervalo de tempo definido pelo utilizador) para um servidor Web No que diz respeito à aplicação WEB desenvolvida, esta permite a um gestor de frota efetuar a monitorização dos veículos em circulação/registados no sistema, podendo visualizar a posição geográfica dos mesmos num mapa interativo (Google Maps), dados do veículo (OBDII) e sensores/dispositivos Bluetooth para cada localização enviada pela aplicação Android. O sistema desenvolvido funciona tal como esperado. A aplicação Android foi testada inúmeras vezes e a diferentes velocidades do veículo, podendo inclusive funcionar em dois modos distintos: data logger e data pusher, consoante o estado da ligação à Internet do smartphone. Os sistemas de localização baseados em smartphone possuem vantagens relativamente aos sistemas convencionais, nomeadamente a portabilidade, facilidade de instalação e baixo custo.

Passive MVC och MVVM designmönster i Android : En jämförelse av kodkomplexitet mellan Passive MVC och MVVM

Det mobila operativsystemet Android är idag ett ganska dominerande operativsystem på den mobila marknaden dels på grund av sin öppenhet men också på grund av att tillgängligheten är stor i och med både billiga och dyra telefoner finns att tillgå. Men idag har Android inget fördefinierat designmönster vilket leder till att varje utvecklare får bestämma själv vad som ska användas, vilket ibland kan leda till onödigt komplex kod i applikationerna som sen blir svårtestad och svårhanterlig. Detta arbete ämnar jämföra två designmönster, Passive Model View Controller (PMVC) och Model View View-Model (MVVM), för att se vilket designmönster som blir minst komplext med hjälp av att räkna fram mätvärden med hjälp av Cyclomatic Complexity Number (CCN). Studien är gjord utifrån arbetssättet Design & Creation och ämnar bidra med: kunskap om vilket mönster man bör välja, samt om CCN kan peka ut vilka delar i en applikation som kommer att ta mer eller mindre lång tid att testa. Under studiens gång tog vi även fram skillnader på om man anväder sig av den så kallade Single Responsibilyt Principle (SRP) eller inte. Detta för att se om separerade vyer gör någon skillnad i applikationernas komplexitet. I slutändan så visar studien på att komplexiteten i små applikationer är väldigt likvärdig, men att man även på små applikationer kan se skillnad på hur komplex koden är men också att kodkomplexitet på metodnivå kan ge riktlinjer för testfall.

Applications of a TransFLash in an embedded system debugging

In this paper, the hardware and software design for using a TF card in debugging an embedded system are described. The used hardware platform is designed based on a PXA310 application processor. The Android open source operating system is used as the software platform. The design of the connection circuit between the application processor and the TF card is introduced first. Secondly, the design of the TF card driver program and the method for Android system to mount the TF card are described. In designing the TF driver program, an SPI operation mode and FAT32 file system are used. The transplant of the FAT32 file system is presented more detail. Finally, the paper introduced the system debugging and the test results are given for the TF card used in a video data acquisition unit of a video monitoring. It is shown that high speed data exchange and good universal property can be obtained by using a TF card to download a system image during developing and debugging. The TF card used in debugging can be used as a mass storage in the embedded product without the need of changing the design for debugging the system and it is also convenient for a user to upgrade operating system.

Security testing in Android networks : a practical case study

Android is a new generation of an open operating system directed at mobile devices that are carried every day. The openness of this architecture is leading to new applications and opportunities including a host of multimedia services, new interfaces and browsers, multitasking including support for wireless local, personal and wide area networking services. Security with mobility and wireless connectivity thus becomes even more important with all these exciting developments. Vital security issues such as leakage of private information, file stealing and spambots abound in networks in practice and Android networks continue to be subject to these same families of vulnerabilities. This paper provides a demonstration of such vulnerabilities in spite of the best efforts of designers and implementers. In particular it describes examples of data leakage and file stealing (address books, contact lists, SMS messages, pictures) as well as demonstrating how Android devices can create spambots. © 2013 IEEE.

Herramientas de programación multimedia en IOS y Android

En este proyecto se realiza un estudio sobre herramientas que facilitan la creación y distribución de aplicaciones en distintas plataformas móviles, con el fin de poder seleccionar la herramienta más apropiada en función del proyecto a desarrollar. Previo al estudio de las herramientas para el desarrollo en plataformas múltiples se realiza un estudio de las herramientas y metodologías que facilitan los propietarios de los entornos IOS y Android. Este estudio previo permitirá al lector conocer en más detalle las particularidades de cada uno de estos dos entornos, así como las pautas y buenas prácticas a seguir en el desarrollo de aplicaciones para dispositivos móviles. Una vez finalizado el estudio, el lector sabrá escoger una herramienta de desarrollo adaptada a cada proyecto en función de su objeto, los recursos disponibles y las habilidades de los miembros del equipo de desarrollo. Adicionalmente al estudio, y como ejemplo de aplicación, en el proyecto se realiza un caso práctico de selección de herramienta y aplicación de la herramienta seleccionada a un proyecto de desarrollo concreto. El caso práctico consiste en la creación de un entorno que permite generar aplicaciones para la visualización de apuntes. Las aplicaciones permitirán ver contenidos de tipo multimedia como ficheros de texto, sonidos, imágenes, vídeos y enlaces a contenidos externos. Además estas aplicaciones se generarán sin que el autor de las mismas tenga que modificar alguna de las líneas del código. Para ello, se han definido una serie de ficheros de configuración en los que el autor de la aplicación deberá indicar los contenidos a mostrar y su ubicación. Se han seleccionado recursos de tipo “código abierto” para el desarrollo del caso práctico, con el fin de evitar los costes asociados a las posibles licencias. El equipo de desarrollo del caso práctico estará formado únicamente por el autor de este proyecto de fin de grado, lo que hace del caso de estudio un desarrollo sencillo, de manera que su futuro mantenimiento y escalabilidad no deberían verse afectados por la necesidad de contar con equipos de desarrolladores con conocimientos específicos o complejos. ABSTRACT. This document contains a study of tools that ease the creation and the distribution of the applications through different mobile platforms. The objective o this document is to allow the selection of the most appropriate tool, depending on the development objectives. Previous to this study about the tools for developing on multiple platforms, a study of IOS and Android tools and their methodologies is included on this document. This previous analysis will allow the reader to know in more detail the peculiarities of each of these environments, together with theirs requirements and the best practices of the applications development for mobile devices. By the end of this document the reader would be able to choose the adequate development tool for a project depending of its objective, its available resources and the developers team’s capabilities. Beside this study and as example of case study this final project includes a practical case of tool selection and its application to a specific development. The case study consists in the creation of an environment that allows generating applications to visualise notes. These applications will allow seeing contents of multimedia type such as: text files, sounds, images, videos, and links to external content. Furthermore these applications will be generated without their author having to modify any line of code, because a group of configuration files will be defined for such purpose. The author of the application only has to update this configuration with the content to show by the application and its location. The selected resources for the case study were of the type “open source” in order to avoid the cost associated to the potential licenses. The developers’ team for this case study has only one member, the author of this final project document and practical case developer. As a result the case study is a very simple development in a way that the future potential maintenance and scalability should not depend on the necessity of a highly qualified developers’ teams with a very specific knowledge on mobile platforms development.

Interacción con juguetes para usuarios con discapacidad usando equipos con S.O. Android

El proyecto realizado, trata de una aplicación desarrollada en la plataforma Android, orientada a personas con algún tipo de discapacidad sensorial o psíquica. Dicha aplicación fomenta el uso y la integración de dispositivos móviles en este tipo de sector de población. Está pensada, para que, un usuario con discapacidad, pueda interactuar con ella y de forma transparente a él, se ha creado un sistema mediante el cual, se registra todo el comportamiento que ese usuario ha tenido durante el tiempo de uso de la aplicación, con el fin de llevar un seguimiento del mismo; evaluar si existen cambios en él; determinar si son necesarios algunos cambios en la aplicación que favorezcan una mejoría en cuanto al uso y consecución de resultados en el paciente, etc. Se ha combinado el uso de una aplicación instalada sobre un sistema operativo de libre distribución, concretamente Android, con un juguete de código abierto, como es Sphero. Eso ha permito el desarrollo de una aplicación perfectamente ajustada a los requisitos funcionales definidos, con una robustez y eficiencia similar a una aplicación de sistemas operativos móviles cerrados. Es importarte remarcar, que la primera finalidad de este proyecto es ofrecer la posibilidad de usar un juguete, como Sphero, que está orientado a un sector de población sin discapacidad, haciendo uso de cualquier dispositivo móvil, a personas con diferentes grados de discapacidad sensorial, motora y psíquica. Siempre clarificando, que no existe la posibilidad de usar esta aplicación para cualquier tipo y grado de discapacidad, ya que, ello supondría, un proyecto de una envergadura enorme. El hecho de usar un dispositivo móvil, es un derecho, que todos tenemos. Y por ello, se espera que tras la lectura y comprensión de este proyecto, se motive a los lectores a seguir desarrollando aplicaciones para que cualquier usuario, con discapacidad o no, tenga las mismas oportunidades de interactuación con dispositivos móviles. The carried out project, is an application developed on the Android platform , aimed at people with some kind of sensory or mental disability . This application encourages the use and integration of mobile devices in this type of population sector. It is designed to be interacted by a disable person and transparently to that user, it has been created a system by which all behavior, that user has had during the time of use of the application, is recorded, that’s to keep track of it ; assess whether there are changes in it, determine if changes are needed in the application that favor an improvement in the use and achieving patient outcomes , etc. . It has combined the use of an application installed on an open source operating system, namely Android, an open source toy , as is Sphero . That has made it possible to develop an application perfectly adjusted to the functional requirements defined with a robustness and efficiency similar to a mobile OS application closed. It is important to note, that the first aim of this project is to offer the possibility of using a toy, like Sphero , which is geared to a sector of the population without disabilities , using any mobile device , for people with different degrees of sensory impairment , motor and mental . Always clarifying that there is no possibility to use this application for any type and degree of disability, because the magnitude of the project would have been infinitely greater. The fact of using a mobile device, is a right we all have. And so, it is expected that upon reading and understanding of this project, motivate readers to continue developing applications for any user , disabled or not, have the same opportunities for interaction with mobile devices .

Case study on mobile applications UX: effect of the usage of a crosss-platform development framework

Cross-platform development frameworks for mobile applications promise important advantages in cost cuttings and easy maintenance, posing as a very good option for organizations interested in the design of mobile applications for several platforms. Given that platform conventions are especially important for the User eXperience (UX) of mobile applications, the usage of framework where the same code defines the behavior of the app in different platforms could have negative impact in the UX. The objetive of this study is comparing the cross-platform and the native approach for being able to determine if the selected development approach has any impact on the users in terms of UX. To be able to set a base line under this subject, study on cross-platform frameworks was performed to select the most appropriate one from a UX point of view. In order to achieve the objectives of this work, two development teams have developed two versions of the same application; one using framework that generates Android and iOS versions automatically, and another team developing native versions of the same application. The alternative versions for each platform have been evaluated with 37 users with a combination of a laboratory usability test and a longitudinal study. The results show that differences are minimal in the Android version, but in iOS, even if a reasonable good UX can be obtained with the usage of this framework by an UX-conscious design team, a higher level of UX can be obtained directly developing in native code.

Lecciones prácticas de desarrollo de aplicaciones móviles en Android

Los avances que se han producido en los últimos años en cuanto a potencia y capacidades de los teléfonos móviles que usamos de manera cotidiana, traen de la mano un auge en la demanda de aplicaciones de todo ámbito: desde aplicaciones generales de consumo, pasando por juegos, hasta aplicaciones que ofrecen soluciones internas a empresas. Existen diferentes sistemas operativos para teléfonos móviles como se explicará más adelante en el capítulo introductorio. En dicho capítulo se da la justificación de por qué en el presente Proyecto Fin de Carrera se centra en el estudio del sistema operativo Android. Primeramente se dará una visión global del estado del arte en cuanto al mundo de aplicaciones móviles se refiere. Se explicarán los pros y contras de cada sistema operativo, detallando el lenguaje de programación utilizado en cada uno de ellos y sus principales características. Después, en el capítulo tres se estudiará con más profundidad el sistema operativo Android, desde su historia y orígenes, hasta los componentes básicos para la creación de una aplicación, pasando por la arquitectura interna del sistema o su máquina virtual. Con esto se pretende que el lector tenga un contexto que le permita comprender los siguientes capítulos, que es donde está el núcleo de este Proyecto Fin de Carrera. El cuarto capítulo trata de una serie de prácticas incrementales, que cubren una gran parte de las posibilidades que ofrece el sistema operativo Android para el desarrollo de aplicaciones. Se ha pretendido que la dificultad vaya de menos a más y que las prácticas se vayan apoyando en las anteriores, para tener al final una única solución que englobe todas las lecciones. El último capítulo quiere englobar el uso de todas las lecciones aprendidas en las lecciones anteriores para crear una aplicación que bien podría ser una aplicación real para un cliente. Se trata de una aplicación que muestra en tiempo real información sobre las cámaras de tráfico de la ciudad de Madrid. ABSTRACT. The improvements that have occurred in recent years in terms of power and capabilities of mobile phones that we use on a daily basis, bring an increment in demand for all kind of applications, from general consumer applications, games or even internal applications that offer solutions to companies. There are different operating systems for mobile phones as will be explained later in the introductory chapter. In that chapter the answer for why this Thesis focuses on the study of the Android operating system is given as well. First an overview of the state of the art about the world of mobile applications will be referred. The pros and cons of each operating system will be explained, detailing the programming language used in each of them and their main characteristics. Then in chapter three will be discussed in more depth the Android operating system, from its history and beginnings to the main components for the creation of an application, to the internal architecture of the system or virtual machine. The goal of chapter three is to give the readers a context that allows them to understand the following chapters, where the core of this Thesis is. The fourth chapter contains a series of incremental practices covering a large part of the potential of the Android operating system for application development. Those practices grow in difficulty and are supported by the previous in order to have at the end a single solution that fits all lessons. The last chapter wants to embrace the use of all the lessons learned in previous lessons to create an application that could well be an actual application for a client. It is an application that displays real-time information off traffic cameras of the city of Madrid.
