Main Abstract:
Driven by the popularity of the Android system, Android app markets enjoy a booming prosperity in recent years. One critical problem for modern Android app markets is how to prevent apps that are going to receive low ratings from reaching end users. For this purpose, traditional approaches have to publish an app first and then collect enough user ratings and reviews so as to determine whether the app is favored by end users or not. In this way, however, the reputation of the app market has already been damaged. To address this problem, we propose a novel technique, i.e., Sextant , to detect low rating Android apps based on the .apk files.With our proposed technique, an Android app market can prevent from risking its reputation on exposing low rating apps to users. Sextant is developed based on novel static analysis techniques as well as machine learning techniques. In our study, our proposed approach can achieve on average 90.50 precision and 94.31 recall.

[1]: During the recent years, the market of mobile software applications (apps) has maintained an impressive upward trajectory. Many small and large software development companies invest considerable resources to target available opportunities. As of today, the markets for such devices feature over 850K+ apps for Android and 900K+ for iOS. Availability, cost, functionality, and usability are just some factors that determine the success or lack of success for a given app. Among the other factors, reliability is an important criteria: users easily get frustrated by repeated failures, crashes, and other bugs; hence, abandoning some apps in favor of others. This paper reports a study analyzing how the fault- and change-proneness of APIs used by 7,097 (free) Android apps relates to applications' lack of success, estimated from user ratings. Results of this study provide important insights into a crucial issue: making heavy use of fault- and change-prone APIs can negatively impact the success of these apps.

[2]: The "free app" distribution model has been extremely popular with end users and developers. Developers use mobile ads to generate revenue and cover the cost of developing these free apps. Although the apps are ostensibly free, they in fact do come with hidden costs. Our study of 21 real world Android apps shows that the use of ads leads to mobile apps that consume significantly more network data, have increased energy consumption, and require repeated changes to ad related code. We also found that complaints about these hidden costs are significant and can impact the ratings given to an app. Our results provide actionable information and guidance to software developers in weighing the tradeoffs of incorporating ads into their mobile apps.

[3]: The tremendous rate of growth in the mobile app market over the past few years has attracted many developers to build mobile apps. However, while there is no shortage of stories of how lone developers have made great fortunes from their apps, the majority of developers are struggling to break even. For those struggling developers, knowing the “DNA” (i.e., characteristics) of high-rated apps is the first step towards successful development and evolution of their apps. In this paper, we investigate 28 factors along eight dimensions to understand how high-rated apps are different from low-rated apps. We also investigate what are the most influential factors by applying a random-forest classifier to identify high-rated apps. Through a case study on 1,492 high-rated and low-rated free apps mined from the Google Play store, we find that high-rated apps are statistically significantly different in 17 out of the 28 factors that we considered. Our experiment also shows that the size of an app, the number of promotional images that the app displays on its web store page, and the target SDK version of an app are the most influential factors.

[4]: One of the most popular ways to monetize a free app is by including advertisements in the app. Several advertising (ad) companies provide these ads to app developers through ad libraries that need to be integrated in the app. However, the demand for ads far exceeds the supply. This obstacle may lead app developers to integrate several ad libraries from different ad companies in their app to ensure they receive an ad with each request. However, no study has explored how many ad libraries are commonly integrated into apps. Additionally, no research to date has examined whether integrating many different ad libraries impacts an app's ratings. This article examines these two issues by empirically examining thousands of Android apps. The authors find that there are apps with as many as 28 ad libraries, but they find no evidence that the number of ad libraries in an app is related to its possible rating in the app store. However, integrating certain ad libraries can negatively impact an app's rating.
There are also a group of studies that examine the relationship between the rating and features of apps. Tian and colleagues [3] found that the size, code complexity, and other 15 features have positive correlations with the star ratings. Linares-Vasquez and colleagues [1] studied the relationships of API changes in Android apps and star ratings. Ruiz and colleagues [4] studied the correlation between ad libraries and ratings of Android apps. Gui and colleagues [2] studied the relationship between energy consumption and ratings of Android apps. Although the conclusions of these techniques are interesting, they do not have a method to predict or classify low rating apps.
