Method, device and terminal device for processing application notification message

The embodiment of the invention provides a method, device and terminal device for processing an application notification message. The method includes the steps that when the application notification message is acquired by an application which runs in background, the application notification message is packaged into a notification bar object, and the application is registered into a desktop starter in advance; inter-process communication is conducted on the notification bar object through a content provider corresponding to an operating system, so that the application notification message carried in the notification bar object is transmitted to a desktop application which is in a running state at present; an area is displayed in a desktop corresponding to the desktop application, and thus the application notification message can be displayed. By means of the method, device and terminal device for processing the application notification message, the application notification message acquired by the application which is in a background running state can be displayed on the desktop, user operation is reduced substantially in the displaying process of the application notification message, and therefore the power consumption of the terminal device is reduced.
