Android Game, Ryan Weston
Android Game, Ryan Weston
Williams Honors College, Honors Research Projects
The purpose of this project was to create an endless runner game for Android coded in Java and XML and developed in Android Studio. In the game, the player controls a frog that jumps from lily pad to lily pad to avoid logs moving toward the player. The player must also maneuver the lily pads as they can randomly disappear. There are three difficulties in the game that vary the disappearance rate of lily pads as well as the frequency and acceleration rate of the log obstacles. The game also has a scoring system and saves the high score locally …

Sudoku App: Model-Driven Development Of Android Apps Using Ocl?, Yoonsik Cheon, Aditi Barua

Model driven development (MDD) shifts the focus of software development from writing code to building models by developing an application as a series of transformations on models including eventual code generation. Can the key ideas of MDD be applied to the development of Android apps, one of the most popular mobile platforms of today? To answer this question, we perform a small case study of developing an Android app for playing Sudoku puzzles. We use the Object Constraint Language (OCL) as the notation for creating precise models and translate OCL constraints to Android Java code. Our findings are mixed in …

To devise efficient approaches and tools for detecting malicious packages in the Android ecosystem, researchers are increasingly required to have a deep understanding of malware. There is thus a need to provide a framework for dissecting malware and locating malicious program fragments within app code in order to build a comprehensive dataset of malicious samples. Towards addressing this need, we propose in this work a tool-based approach called HookRanker, which provides ranked lists of potentially malicious packages based on the way malware behaviour code is triggered. With experiments on a ground truth of piggybacked apps, we are able to automatically …

The number of Android applications has increased rapidly as Android is becoming the dominant platform in the smartphone market. Security and privacy are key factors for an Android application to be successful. Android provides a permission mechanism to ensure security and privacy. This permission mechanism requires that developers declare the sensitive resources required by their applications. On installation or during runtime, users are required to agree with the permission request. However, in practice, there are numerous popular permission misuses, despite Android introducing official documents stating how to use these permissions properly. Some data mining techniques (e.g., association rule mining) have …

Research has found that Americans spend 4.5 hours watching television, 1.5 hours listening to the radio, about half an hour reading print and spend a whooping five plus hours per day in digital media (online, mobile, other). Out of these five hours, two hours and twenty minutes are spent on a mobile device (phone or tablet), which is a massive increase of about 575 percent from the twenty-four minutes that was reported in 2010. Flurry, an analytic app company, released data about their tracking of more than 300,000 apps in 2013, and they found the average time spent per day …

Over 65% percent of food consumed in the United States is pollinated by bees. Unfortunately, due to poor farming practices, pesticides are sprayed in bee sensitive areas unknowingly and as a result, the bee population is dwindling at an alarming rate. With lesser bees to pollinate crops, produce is compromised on a very large scale and this could have disastrous impacts on the nation's needs for food. Apiarists and beehive owners face the major responsibility of ensuring that their hives aren't affected by dangerous insecticides and pesticides from the farming areas that they might visit during their crop pollination cycles …
Extending Java For Android Programming, Yoonsik Cheon
Extending Java For Android Programming, Yoonsik Cheon
Departmental Technical Reports (CS)
Android is one of the most popular platforms for developing mobile applications. However, its framework relies on programming conventions and styles to implement framework-specific concepts like activities and intents, causing problems such as reliability, readability, understandability, and maintainability. We propose to extend Java to support Android framework concepts explicitly as built-in language features. Our extension called Android Java will allow Android programmers to express these concepts in a more reliable, natural, and succinct way.
