android operating system an (OS) is open-source, easy to use, and user-friendly mobile OS. In this way, it is very preferred. As a result, it becomes the target of malicious people. Applications installed on the android OS from the Google Play Store or by third-party application providers, also known as android Package Files (APKs), may contain malicious software. So far, a variety of analyzes and detections have been made to detect such malware. While detecting malware, good results have been obtained with various methods, but malicious people have developed methods of hiding themselves against these methods. We propose a new feature selection method based on Firefly Optimization Algorithm (FOA) with the Fuzzy Set-Based (FSB) weighting method. The proposed method performs better than traditional feature selection methods with fewer features. The experimental results of this study proved that FOA is an acceptable optimization algorithm for feature selection to detect malware in terms of classification performance and classification runtime. In addition, experimental evaluation of TF-IDF and FSB weighting methods indicates the effectiveness of the FSB weighting with a full feature set.

In Los Olivos district, Lima, Peru, a large amount of solid waste is produced, which is one of the main causes that contribute to environmental pollution. To help decrease pollution, the design of a mobile application, with specific activities of easy and simple operation, was developed. The mobile application was designed with Balsamiq Mockup, and developed on android operating system. This mobile application would allow people to know in real time how far away the solid waste collection services are. In this way, we seek to make people aware of the benefit that will bring to their health, since everyday people always generate solid waste or some type of unnecessary waste. In addition, waste collection points will be implemented, generating a greater benefit to the population of Los Olivos district. The bad habit of polluting would be left behind and a great step towards the solution would begin, to recycle. Also, the population would be part of the big change to have a better district that would avoid environmental pollution.

In the last four years, the number of smartphones capable to read user fingerprints in order to perform authorization and authentication has tripled. Also, after the introduction of biometric payment services, fingerprint scanner driven authentication became more popular and the variety of smartphones equipped with this kind of sensor multiplied. However, the implementation methods are directly handled by manufacturers, who are often making decisions under the pressure of a short time-to-market. Starting from these facts, scholars and industry leading experts started to research the documentation in order to analyze the privacy and security flaws of the existing implementations. the assessment of android good practice advises has revealed that some devices were not compliant, due to the fact that architecture could be attacked by an adversary both from the external world and by using malicious applications. Most common types of attacks against fingerprint authentication which could be demonstrated were aiming either to confuse the user in order to perform a malicious operation without a proper context or by employing custom-made molds of the user thumb minutiae. This paper analyses former and current issues affecting the fingerprint authentication in mobile devices powered by the android operating system.

To make smartphones more powerful, researchers have proposed many techniques to improve the performance of mobile systems and applications. As the most popular mobile operating system, android is based on the Linux kernel. Therefore optimizing kernel performance can potentially accelerate android smartphones. In this paper, we propose a compiler-based approach to constructing device-specific optimized Linux kernels for android smartphones. By utilizing runtime feedback from the device, we can instruct the compiler to perform profile-guided optimization (PGO) and produce a Linux kernel image optimized specifically for the device, which can be shipped together with the device when it is manufactured, or released later in an update of the whole system. To the best of our knowledge, this paper is the first work that successfully applies PGO to the Linux kernel on android smartphones to gain performance improvement. We conduct experiments on three different android smartphones, namely Nexus 5X, Nexus 6 and Nexus 5. Results show that system performance improves by 11.1%, 4.1% and 9.3% on average, respectively. Specifically, we measure performance improvements of key android system components such as multithreading and task scheduling, Binder, and storage and file systems.

The android operating system utilizes the Linux kernel. This kernel has a function that dynamically adjusts the CPU clock frequency to control the obtained performance and the power consumed. However, because this kernel was primarily developed for server computers, it may not suitably optimize the clock frequency in smartphones. In this paper, we focus on optimization of the clock frequency of smartphones running the android operating system. First, we propose a method that modifies this mechanism less aggressively. Then, we evaluate the proposed method and demonstrate that the modified method decreases the power consumed by the CPU without any significant performance decline. For example, experimental result shows that, in the case of a game application, the proposed method decreased the power consumption by 7.28% with only 0.68% processing time increase.

Given the increasing competition in mobile-app ecosystems, improving the user experience has become a major goal for app vendors. App Store 2.0 will exploit crowdsourced information about apps, devices, and users to increase the overall quality of the delivered mobile apps. App Store 2.0 generates different kinds of actionable feedback from the crowd information. This feedback helps developers deal with potential errors that could affect their apps before publication or even when the apps are in the users' hands. The App Store 2.0 vision has been transformed into a concrete implementation for android devices. This article is part of a special issue on Crowdsourcing for Software Engineering.

Judo is a martial art that was created as a physical, intellectual and moral education method in Japan. In competition matches, Judo is a combat sport where two athletes fight against each other. Judo matches are ruled by different scores, penalties and durations, which change regarding the age and gender of the competitors. There is a need to record the actions in favour of or against a judoka during a match in order to create an efficient training programme as well as technical and tactical development strategies for each competitor. In this work, a technological solution is presented;it records each athlete's matches and scores, penalties, pauses during the match and its actual length of time. These aspects can help to create charts reflecting efforts made by the judoka. The research is focused on the support of the technical-tactical analysis of judo matches, taking into account recent information technology and communications trends: (1) the solution is developed for mobile devices which use the android operating system, (2) the solution takes advantage of Cloud computing to allow ubiquitous access to the data and (3) the desktop component of the solution is portable to many computer systems because it has been developed using the Java programming language. The initial results show how the technological solution can be used for improving the performance of the athlete by providing feedback of the behaviour of the judoka during each match.

Many web applications provide secondary authentication methods, i. e., secret questions (or password recovery questions), to reset the account password when a user's login fails. However, the answers to many such secret questions can be easily guessed by an acquaintance or exposed to a stranger that has access to public online tools (e. g., online social networks);moreover, a user may forget her/his answers long after creating the secret questions. Today's prevalence of smartphones has granted us new opportunities to observe and understand how the personal data collected by smartphone sensors and apps can help create personalized secret questions without violating the users' privacy concerns. In this paper, we present a Secret-Question based Authentication system, called " Secret-QA", that creates a set of secret questions on basic of people's smartphone usage. We develop a prototype on android smartphones, and evaluate the security of the secret questions by asking the acquaintance/stranger who participates in our user study to guess the answers with and without the help of online tools;meanwhile, we observe the questions' reliability by asking participants to answer their own questions. Our experimental results reveal that the secret questions related to motion sensors, calendar, app installment, and part of legacy app usage history (e.g., phone calls) have the best memorability for users as well as the highest robustness to attacks.
