摘要： 在开发新的需求功能或维护已有代码的过程中,安卓应用开发者会尝试获取与特定主题功能相对应的代码片段并了解其逻辑结构。当涉及代码层次上的分析工作时,复杂的源代码结构以及开发者不良的代码风格将会导致开发者需要花费大量的时间去定位代码片段并理清实现逻辑。因此,找出一种能够快速定位到代码片段的方法对于开发者具有重要的实际意义。提出了一种面向场景的安卓应用代码定位方法,其目标是根据特定主题功能的执行场景,综合运用动态与静态相结合的分析技术来确定与该主题功能相关的代码片段。此方法的执行步骤包括主题功能执行轨迹的收集与分析、安卓应用源代码的静态分析、基于静态与动态方法信息的匹配与综合以及方法信息的可视化展现。基于该方法实现了一款插件工具,该工具支持用户便捷查找与主题功能相关的代码信息,并支持高亮标记用户所指定的方法片段。
