The invention discloses an application interface providing method and an application interface providing device. The method includes the following steps: dividing search keywords inputted by a user into at least one keyword unit; matching the divided keyword units with application interfaces stored in an application interface bank respectively; determining attributes of input frames contained in a matched application interface; aiming at the input frames contained in the matched application interface and according to the divided keyword units, determining attribute values corresponding to the attributes of the input frames and filling the determined attribute values in the input frames; providing the application interface with the attribute values filled in to the user. By the method and the device, the problem that much electric quantity of a mobile terminal is consumed due to the fact that the user selects the input frames for several times and inputs information repeatedly and then a great many of processing resources of the mobile terminal are consumed in the prior art is solved.
