代码质量不佳会导致不可预测的行为。对于用户来说,通常表现为可用性差。对于攻击者来说,提供了以意外方式对系统施加压力的机会。
Android Bad Practices: Use of Released Media Resource
Abstract
代码在 Android 媒体对象释放后对其进行了引用。
Explanation
在媒体对象释放后,代码试图使用该对象。在未重新获取媒体对象的情况下任何对该资源的进一步引用都将抛出异常。如果未捕获该异常,可能会导致应用程序崩溃。
示例:以下代码使用切换按钮来切换媒体播放。用户按此按钮后,当前歌曲或视频就会停止,并将释放照相机资源。但是,如果再按一次按钮,将调用之前释放的媒体资源中的
