Analysis of Common User Flows in Open-Source Android Applications
(Tartu Ülikool, 2023) Käosaar, Kristofer; Rahkema, Kristiina, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
Many project templates for Android applications can be found on GitHub, but few contain implementations of whole user flows. This thesis focuses on extracting representations of user flows in the form of activity diagrams from existing open-source Android applications, with the goal to develop a project template featuring user flows such as onboarding, user creation and signing in. The activity diagrams of each user flow were combined with the intention of creating a representation of an average user flow that could be applied to most use cases. The project template was developed based on those combined activity diagrams in Android Studio using Kotlin and following a Model-View-ViewModel architecture. The project template was evaluated by recreating user flows of six open-source Android applications and measuring how much of the codebase needed to be changed to achieve a similar user interface. The result indicates that systematically analysing the user flows of existing applications is a useful starting point for creating easily adaptable project templates.

Building a tool for detecting code smells in Android application code
(Tartu Ülikool, 2020) Mõškovski, Stanislav; Rahkema, Kristiina, juhendaja; Pfahl, Dietmar, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
In recent years, quality of the code behind the presentation layer has become increasingly important since a high number of applications are in maintenance mode. Maintaining complex applications is hard and modifying code that is difficult to understand may introduce new bugs. Poor design or implementation choices that contribute to technical debt are called code smells. Static analyzers are tools used to detect code smells and other vulnerabilities inside software applications. In this paper, we analyze static analysis tools and also develop an alternative, which tries to overcome the shortcomings of the previous tools by providing more code smell detection rules. As a result, we developed a plugin for SonarQube that analyzes applications written in Java programming language. Finally, we verified our tool by performing an empirical study on a selected corpus of applications.

Evaluating Maintainability of Android Applications: Mooncascade Case Study
(Tartu Ülikool, 2021) Öztürk, Mustafa Ogün; Mass, Jakob, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
Android became one of the most comprehensive mobile platforms in the last decade. This comprehensiveness also brought more challenges to the Android application development. Android’s nature, demanding business needs, the frequent update rate of Android applications, and lastly, changing development teams are the four major challenges for Android applications. Maintainability is defined as how easy it is to update, modify, and maintain software. At this point, maintainability emerges as a key concept because developing maintainable Android applications facilitate the above-mentioned difficulties. The primary goal of this study is to evaluate the impact of the technologies and the methods used to develop Android applications by Mooncascede, a software product development company, on maintainability. These methods and technologies include principles (e.g. Clean Code, SOLID), architectural/design patterns (Clean Architecture, MVVM), and third-party libraries (RxJava, Dagger 2 and so on). The evaluation was conducted using the triangulation strategy, which is a mixed-method approach. Qualitative evaluation was conducted via interviews with the case company’s Android team (7 participants) and an Android developer survey filled by anonymous developers (over 150 participants). Also, quantitative evaluation was made via object-oriented software metrics. Study results reveal the positive impact of the evaluated methods and technologies on the maintainability of Android applications while pointing to the need for improvements. Results also indicate the need for a new maintainability model specific to the Android applications.

Generating Process-based Mobile Applications for the Internet of Things using Automated Planning
(Tartu Ülikool, 2020) Kaio, Kelian; Mass, Jakob, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
Smartphone devices are being used by more than half of the world population, and this means more opportunities to create mobile applications that help people with their daily lives. This thesis is looking into mobile apps for the Internet of Things, which are used in areas like smart homes, transportation, and healthcare. However, because of the massive scale of smart devices, supporting all of them is not feasible. Automated planning can help the application adapt to user’s and device’s context and support only those IoT devices which are needed by creating user-specific plans. These plans can be mapped into a business process model so the mobile application could execute them by using a business process engine. The goal of this thesis is to investigate and develop a framework that enables creating dynamic IoT mobile applications, using automated planning and business software management while taking into account user’s preferences and mobile device capabilities. Furthermore, it is analyzed which type of planning algorithm fits best for the motivating scenario. A framework prototype consisting of mobile application and backend is created for the motivating scenario is created as a proof of concept. The performance and scalability of the chosen planning algorithm and the developed prototype are evaluated.

Intercepting Mobile-ID SIM Toolkit Calls On Android
(Tartu Ülikool, 2023) Mander, Karl Erik; Paršovs, Arnis, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
This thesis investigates the security risk of intercepting Mobile-ID SIM Toolkit calls on Android. The investigation is done by modifying the Android operating system with malware. Through an in-depth analysis of the communication protocol between an Android phone and a SIM card, this study demonstrates that attackers who have gained access to the victim’s phone through illegitimate apps or other exploits with root privileges may be able to remotely control Mobile-ID operations by intercepting SIM card communications. From there on, the system could complete all Mobile-ID transactions surreptitiously and automatically. This thesis aimed to research the security architecture of Android OS concerning Mobile-ID and discuss possible options that a malware creator would have to implement to achieve SIM command intercepting capabilities.

Mobile AR Point Cloud Matching
(Tartu Ülikool, 2021) Sillaots, Karl - Walter; Tunnel, Raimond-Hendrik, juhendaja; Kallaste, Timo, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituut
This thesis explains the process of point cloud matching, to assess its viability in mobile markerless augmented reality solutions. Traditional point cloud matching algorithms like 4-Point Congruent Systems are described and considered. 2 Point Normal Sets was chosen for real-world experimentation due to being faster and easier to implement. Additional ideas to improve performance were implemented in addition to the chosen algorithm: A pair limiter that only uses up to 100 pairs each iteration for the matching process, changing the algorithm to only perform rotations across one axis and a point sampler to reduce the amount of points used. The best values for rotation error delta were also analyzed. The first experiment done was with a point cloud in the shape of a rectangular box, to confirm if the additional ideas did improve performance. For the second experiment, various point cloud scans were made of a real-world room in Gallery Pallas. The algorithm was tested using these scans and the experiment results were documented. For the third experiment, an additional limiter was added to the point cloud scanner, so that it would only accept points closer than 2 meters from the scanner. This was done for more accurate point clouds. A second set of tests were done with this modification and the experiment results written. The fourth and final experiment was done on a mobile device. While the previous experiments showed promise and improvements with each advancement, the algorithm had problems on a mobile device when matching against a unique point cloud for each run. Since there were still good matches, the possibility of using point cloud matching for markerless augmented reality is there, but would require additional work before it can be considered usable in applications.
