step S104, judging whether the current operation scene is a preset operation scene or not, and storing the monitoring data into a preset storage area when the current operation scene is the preset operation scene;

step S105, reading monitoring data from a preset storage area at preset interval time, and acquiring the bit number of file data generated in a preset operation scene from the monitoring data;

and S106, when the bit number is larger than or equal to a preset bit number, determining the type of the file to be cleaned according to the preset operation scene, and cleaning the file of the type of the file to be cleaned from the file data generated in the preset operation scene.

The method comprises the steps that after monitoring data are obtained, whether a current operation scene is a preset operation scene or not is judged, when the current operation scene is the preset operation scene, the monitoring data are stored in a preset storage area, then the monitoring data are read from the preset storage area at preset intervals, the bit number of file data generated under the preset operation scene is obtained from the monitoring data, finally when the bit number is larger than or equal to the preset bit number, the type of a file to be cleaned is determined according to the preset operation scene, the file of the type of the file to be cleaned is cleaned from the file data generated under the preset operation scene, the preset operation scene is a foreground operation scene, and the corresponding types of the file to be cleaned are an application residual file, a system garbage file, an invalid installation package file, a thumbnail cache file, a temporary data file and the like.

In this embodiment, the monitoring data acquired by the monitoring running application is stored in the preset storage area in the foreground running scene, so that the text data generated in the foreground running scene in the subsequent application is conveniently cleaned when the number of the text data exceeds a certain number of bits, and the application running fault caused by cleaning the text data generated by the application in the foreground running scene is avoided.

Further, based on the third embodiment described above, a fourth embodiment of the freeze prevention method of the present invention is proposed, which is different from the foregoing embodiments in that after the step S106, the freeze prevention method further includes:

The mobile terminal cleans files of the type of the files to be cleaned from the file data generated in a preset operation scene, acquires the cleaned file data, compresses the cleaned file data to acquire compressed file data, calculates the bit number of the compressed file data, generates file cleaning prompt information when the bit number exceeds a preset threshold value, and displays the file cleaning prompt information.

In this embodiment, the invention compresses the cleaned file data to obtain compressed file data, and then prompts a user to manually clean the compressed file data when the compressed file data exceeds a certain bit number.

Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where a freeze-screen prevention program is stored on the computer-readable storage medium, and when executed by a processor, the freeze-screen prevention program implements the following steps:

The specific embodiment of the computer-readable storage medium of the present invention is substantially the same as the specific embodiments of the freeze-screen prevention method described above, and will not be described herein again.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or system that comprises the element.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) as described above and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, an air conditioner, or a network device) to execute the method according to the embodiments of the present invention.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
