每當我在屏幕上做某事時，就會出現更多的surfaceflinger屏幕截圖條目。 我想知道是否有任何間諜活動，或者這有一些簡單的解釋。

任何幫助理解為什么這些條目不斷出現？

Answer 1

引用與android-surfaceflinger相關的問題的答案

SurfaceFlinger 是一個 Android 系統服務，負責將所有應用程序和系統表面合成到一個緩沖區中，最終由顯示器 controller 顯示。

所以它只是分配幀緩沖區。 從事這項工作的開發人員保留了這些日志。 正如您所提到的，其中有帶有屏幕截圖字樣的日志，這可能是您擔心的原因。

因此，為了簡單起見，無需擔心這些日志。

我想知道有沒有什么間諜活動？

我檢查了我的設備和模擬器，也有來自我的設備的日志，所以如果它是由於某些間諜活動引起的，那么它只會出現在你的設備上，而不是出現在我的設備或模擬器上。 如果它是間諜，那么今天的世界就會知道它。 今天，每個人都關心隱私。 所以你不需要擔心那些日志
