To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

A first embodiment of the present disclosure provides a method for playing data, where the flow of the method is shown in fig. 1, and the method includes steps S101 to S103:

s101, detecting whether the current operation memory value of the system reaches a preset threshold value according to a preset time interval.

The advertisement terminal is usually implemented by running an APP (application program), that is, the advertisement terminal plays advertisement data using a predetermined APP, so that it must start a process of the predetermined APP when the predetermined APP starts to run, the process is a first process in this embodiment, that is, a main process in which the predetermined APP runs, and when the predetermined APP runs, the first process is started to play third predetermined data.

The third predetermined data may be calculated from when the predetermined APP starts playing until it is determined that the current running memory value reaches the predetermined threshold, that is, the complete advertisement data in the process, for example, when it is determined that the current running memory value reaches the predetermined threshold, 120 advertisement data have been played and 121 th advertisement data are being played, the 121 th advertisement data is a video advertisement, at this time, the video advertisement has been played for 3 seconds, and is not played for 7 seconds, and after the advertisement data that have not been played for 7 seconds are all played, the third predetermined data (i.e., the first 121 advertisement data) is formed. Of course, the third predetermined data may also be based on a time when the current running memory value reaches the predetermined threshold, that is, in the process, in order to ensure that the viewer has the best use experience, the second process may be started after the advertisement data is played once.

In order to ensure that no bad user experience such as program flash back occurs before the third predetermined data is played, when the predetermined threshold is set, the predetermined threshold needs to be smaller than the maximum memory value, so as to ensure that even if the second process is not started immediately, there is enough memory to run the advertisement data of the first process. For example, when the maximum memory value of the system is 2G, the predetermined threshold may be set to 1G or 1.5G, and the like, which may be set by a person skilled in the art according to actual requirements.

S102, when the current running memory value reaches a preset threshold value, a second process is started to play the first preset data, and the first process is closed to release the memory.

In order to ensure the highest response speed of the system, it is preferable that the second process is restarted to play the first predetermined data when the first process finishes playing the third predetermined data.

In concrete implementation, if the current running memory value does not reach the preset threshold value, the third preset data is continuously played through the first process.

S103, after the memory release is finished, the first process is started to play the second preset data, and the second process is closed.

After the memory is released, the memory may be completely released, or the memory may be released until the current running memory value is smaller than a threshold value, where the threshold value needs to ensure that the first process has enough memory to run when set, and may be set to be lower, for example, when the maximum memory value of the system is 2G, the threshold value may be set to 0.2G.

The process of detecting whether the current running memory value of the system reaches the preset threshold value according to the preset time interval can be realized in a first process, namely, a thread is arranged in the first process, when the first process plays advertisement data through Webview, the detection threads work simultaneously, namely, the detection threads are started to execute the detection threads after the first process is started; once the maximum value of the current memory of the system is detected to reach a preset threshold value, a second process is started to play advertisement data, and a first process is closed; then, detecting the current running memory value of the system again, once the memory release is determined to be finished, starting the first process, and closing the second process so as to play the advertisement data by using the first process; and if the current maximum memory value of the system is not detected to reach the preset threshold value, continuing to play the advertisement data by using the first process.

A second embodiment of the present disclosure provides an apparatus for playing data, the apparatus having a structure as shown in fig. 2, and including:

the detection module 10 is configured to detect whether a current operating memory value of the system reaches a predetermined threshold value according to a predetermined time interval; a first executing module 20, coupled to the detecting module 10, configured to start a second process to play the first predetermined data and close the first process to release the memory when the current running memory value reaches a predetermined threshold; the second execution module 30 is coupled to the first execution module 20, and configured to start the first process to play the second predetermined data and close the second process after the memory release is completed.

The advertisement terminal is usually implemented by running an APP (application program), that is, the advertisement terminal plays advertisement data using a predetermined APP, so that it must start a process of the predetermined APP when the predetermined APP starts to run, the process is a first process in this embodiment, that is, a main process in which the predetermined APP runs, and when the predetermined APP runs, the first process is started to play third predetermined data. Therefore, the apparatus for playing data according to the embodiment of the present disclosure may further include a third executing module, coupled to the detecting module, for starting the first process to play the third predetermined data.

The third execution module is further configured to continue to play the third predetermined data through the first process when the current running memory value does not reach the predetermined threshold value.

In order to ensure that the system response speed is highest, the first execution module is specifically configured to start the second process to play the first predetermined data when the first process finishes playing the third predetermined data.

A third embodiment of the present disclosure provides an electronic device, a structural schematic of which is shown in fig. 3, and the electronic device at least includes a memory 901 and a processor 902, the memory stores a computer program, and the processor implements the method provided in any embodiment of the present disclosure when executing the computer program on the memory, and the method includes the following steps S11 to S13:

s11, detecting whether the current operation memory value of the system reaches a preset threshold value according to a preset time interval;

s12, when the current operation memory value reaches the preset threshold value, starting the second process to play the first preset data, and closing the first process to release the memory;

s13, after the memory release is completed, the first process is started to play the second predetermined data, and the second process is closed.

Before executing the computer program on the storage for detecting whether the current running memory value of the system reaches the preset threshold value according to the preset time interval, the processor also executes the following steps: the first process is initiated to play the third predetermined data.

When the processor executes the computer program which starts the second process on the memory to play the first preset data, the following steps are specifically executed: and starting the second process to play the first preset data when the first process finishes playing the third preset data.

After the processor executes the computer program which detects whether the current running memory value of the system reaches the preset threshold value according to the preset time interval on the storage, the following steps are also executed: and under the condition that the current running memory value does not reach the preset threshold value, continuously playing the third preset data through the first process.

Wherein the predetermined threshold is less than the maximum memory value.

According to the method and the device, the auxiliary process is started to play the advertisement shielding, the main process automatically quits and releases the memory, then the auxiliary process is started and recovered to play, and the effect that the App does not flash back to the initial interface and the program is played all the time can be achieved.
