The master's thesis is focused on Java based solution of remote PC control using a mobile phone. Application is made up of client and server, which are communicating via Bluetooth interface. The client represents a mobile application (MIDlet) and commands sent to the server. Server, run on a computer (with any operating system), read these orders and evaluate their algorithms to control the PC. The issue of the draft text is divided into two units, each of them describes just one part of the application. The client describes its functionality. It is also fully examines the structure of mobile application programmed in Java ME, together with the most important methods of this code. Text dealing with the server part describes its activities as well as individual options utilization. It describes the structure of the server application which is programmed in Java SE. There are also a description of the most important methods of the Java SE code. This thesis gives the results of both components of the application that allow to remotely control the computer and especially the presentation. The application was properly debugged and tested, and form a functional multiplatform software.

The purpose of this research was to evaluate the Capuchin API launched by Sony Ericsson at Lund, Sweden in 2008. The Capuchin API bridges Adobe’s Flash graphics and effects with JSR support from Java ME. We evaluated Capuchin API with regard to its suitability for a Mobile TV application. We tested this API in Ericsson’s TV lab where we had access to live TV streams and online multimedia resources by implementing a Mobile TV client. This test application was named “Min TV”, in English: “My TV”. Using Capuchin in the Ericsson TV lab environment has shown that it has some benefits, but also has many drawbacks. The Flash developer can be used to create an animated user interface and Java developers can do complex programming. At this early stage Capuchin technology is not mature enough, nor is it suitable for Mobile TV client development. Only after Sony Ericsson adds features such as soft keys, easier debugging of Flash Lite standalone applications, test emulator support in the software development kit, and more data communication methods than string and number, only then it will be a suitable technology for Mobile TV applications. Ericsson’s current Mobile TV application client was built using a framework called ECAF, which supports a graphics frontend and Java ME as backend. We compared ECAF and Min TV with respect to parameters such as: flexibility, performance, memory footprint, code size, and cost of skinning. (All these parameters are explained in detail in the methodology chapter.) As a possible future technology for Mobile TV, we evaluated a number of different presentation/graphics technologies including HECL, SVG Tiny, MIDP 3.0, .NET Compact Framework, etc. Moreover, we examed if a pure Flash Lite client application is a viable solution for Mobile TV. The comparison of different presentation technologies showed that Java ME is a comprehensive platform for mobile development offering all the necessary support from third party graphical user interface makers. .NET CF also looks like a good option for development with the scaled down capabilities for different programming languages supported using CLR. / Syftet med denna forskning var att utvärdera Capuchin API lanserades av Sony Ericsson i Lund, Sverige 2008. Den Capuchin API broar Adobe Flash grafik och effekter med JSR stöd från Java ME. Vi utvärderade Capuchin API med avseende på dess lämplighet för ett mobil-tv ansökan. Vi testade detta API i Ericssons TV lab där vi hade tillgång till TV-strömmar och online multimediaresurser genom en mobil-TV-klient. Detta test ansökan hette "Min TV", på engelska: "My TV". Använda Capuchin i Ericsson TV lab miljö har visat att det har vissa fördelar, men också många nackdelar. Flash-utvecklare kan användas för att skapa en animerad användargränssnitt och Java utvecklare kan göra komplexa programmering. På detta tidiga stadium Capuchin tekniken inte mogen, det är inte heller lämpliga för mobil-TV-klient utveckling. Först efter Sony Ericsson lägger till detaljer såsom mjuka nycklar, enklare felsökning av Flash Lite fristående program, testa emulator stöd i Software Development Kit, och mer data kommunikationsmetoder än string och antal, först då kommer det att vara en lämplig teknik för mobil-TV-program . Ericssons nuvarande mobil-tv ansökan klient byggdes med hjälp av en ram som kallas ECAF, som stöder en grafiska gränssnittet och Java ME som backend. Vi jämförde ECAF och min TV med avseende på parametrar såsom flexibilitet, prestanda, minne fotavtryck kod storlek och kostnaden för avhudning. (Alla dessa parametrar förklaras i detalj i den metod kapitel.) Som en möjlig framtida teknik för mobil-TV Vi utvärderade ett antal olika presentation / grafik teknik inklusive HECL, SVG Tiny, MIDP 3.0,. NET Compact Framework, etc. Dessutom har vi examed om en ren Flash Lite klientprogrammet är en hållbar lösning för mobil-TV. Jämförelsen mellan olika presentation teknik visade att Java ME är en övergripande plattform för mobila utvecklingen erbjuder allt nödvändigt stöd från tredje part grafiskt användargränssnitt beslutsfattare. . NET CF också ser ut som ett bra alternativ för utvecklingen med ned kapacitet för olika programspråk som stöds med hjälp av CLR.

Many techniques, methods and tools have been proposed helping us to get high level software quality. Due to the increase in the number of mobile devices available daily, there is a high number of software products for such devices are under development. To test the software for mobile devices it is important to know the characteristics of both the device and the software itself aiming at to get high quality products. One package of experimentation aiming at evaluating some well known testing techniques applied in mobile software is proposed. This work describe the proposed package, the results obtained after three replications, and highlight which technique is more adequate for grant quality in Java ME software. The replications occur in a controlled environment, producing a consistent information database about the usage of the testing techniques in JavaME programs. New replications can be carried out for collecting more data and increasing the confidence in the results obtained so far. The final objective, after many replications, is to develop one incremental strategy for testing Java ME software. A preliminary version of this strategy is presented in this work and can be further refined. Moreover, the data obtained during the experiment helps improving the JaBUTi/ME testing tool, aiming at to maximize the support and reduce the cost of the testing activity / A qualidade de software é almejada por todos profissionais da computação.

The aim of this diploma thesis is to study the potential of Java ME platform for receiving and sending of SMS and to utilize obtained information subsequently in implementation of an application for this platform. The first part of the diploma thesis aims at explaining general terms of the Java language and its basic features. The next part deals with specific properties of the Java ME platform and properties of devices that support this platform. A design of the Java ME application based on theoretical knowledge is created then. This application has to be able to receive, process, store and send SMS and communicate with the server application based on the Java SE platform. The created Java ME application serves as an automated SMS voting server, which can be used in mobile devices that support the Java ME platform and can be remote-controlled via Internet from the Java SE platform application. The final chapter presents the results and conclusions of testing of the created application on real mobile devices.
