Taming Android Fragmentation through Lightweight Crowdsourced Testing

Android fragmentation refers to the overwhelming diversity of devices and OS versions. These lead impossibility testing an app on every supported device, leaving a number compatibility bugs scattered in community thereby resulting poor user experiences. To mitigate this, our fellow researchers have designed various works automatically detect such issues. However, current state-of-the-art tools can only be used specific kinds issues (i.e., caused by API signature evolution), i.e., many other essential types are still unrevealed. For example, customized versions real semantic changes could serious issues, which non-trivial detected statically. this end, we propose novel, lightweight, crowdsourced approach, fill research gap enable possibility taming through efforts. Specifically, is emerging alternative conventional mobile mechanisms that allow developers test their products pinpoint platform-specific Experimental results thousands cases real-world show effective identifying verifying API-induced Also, after investigating experience qualitative metrics, users' satisfaction provides strong evidence useful welcome practice.
