[每当我在屏幕上执行某项操作时，就会显示更多的SurfaceFlinger屏幕截图条目。我想知道是否有任何间谍活动，或者有一些简单的解释。

任何帮助您理解为什么这些条目继续出现的原因吗？

Answer 1

引用与android-surfaceflinger相关的问题的答案

SurfaceFlinger是Android系统服务，负责 将所有应用程序和系统表面组合为一个 最后由显示控制器显示的缓冲区。

所以它只是分配帧缓冲区。并且从事该工作的开发人员保留了这些日志。正如您提到的，其中有带有屏幕快照单词的日志，这可能是您担心的原因。

因此，为了简单起见，无需担心这些日志。

我想知道是否有间谍吗？

我检查了我的设备，并且在模拟器上，也有来自我的设备的日志，因此，如果它是由某些间谍行为引起的，那么它只会出现在您的设备上，而不是出现在我的设备或模拟器上。如果它在从事间谍活动，那么今天它将为世界所熟知。今天每个人都在关注隐私。因此，您无需担心这些日志
