摘要： An accessibility service protection application for hiding content of a first application from an accessibility service of a second application on a mobile computing device is described. The accessibility service protection application determines the first application currently active in foreground of the mobile computing device. The accessibility service protection application configures a transparent activity to hide content associated with the first application from the accessibility service of the second application. The accessibility service protection application launches the transparent activity on top of the first application, such that the transparent activity protects the content associated with the first application from the accessibility service of the second application.
