Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The embodiment of the application provides a screen saver display method, which is realized based on an android system as shown in fig. 1, and comprises the following steps:
s101: when the android system meets a first preset condition, a first timer is started; the first preset condition comprises that a server side is configured to start a screen saver and a screen saver switch in the setting of the android system is started.
S102: and setting the default interval time as a preset delay time.
S103: judging whether the timing time of the first timer is equal to a preset time delay time length, if so, acquiring a key trigger time stamp and an audio state time stamp when the android system meets screen saver display conditions, wherein the key trigger time stamp is a time stamp for recording the time length after the system is started when the last key is triggered, and the audio state time stamp is-1 when the android system plays audio and video and is a time stamp for stopping playing the audio and video when the android system does not play the audio and video.
S104: and controlling the screen saver display state based on the current time stamp of the android system, the key trigger time stamp and the audio state time stamp, wherein the current time stamp is a time stamp for recording the time length of the android system after the system is started.
The android device based system monitors all key events in the source code phonewindowmanager.java, namely, as long as a user has key behaviors, the behaviors can be obtained in the intercept Key Before Dispatching method of phonewindowmanager.java.
The system of the Android device has a sleep WAKE mechanism, which is mainly realized through wake_lock, and Android provides five types of WakeLock, namely PARTIAL_WAKE_LOCK, SCREEN_DIM_WAKE_LOCK, SCREEN_BRIGHT_WAKE_LOCK, FULL_WAKE_ LOCK, PROXIMITY _SCREEN_OFF_WAKE_LOCK. When the audio class application plays the audio, a LOCK with a TAG being an AudioMix is held in a PARTIAL_WAKE_LOCK of the system, particularly in an acqueWakeLockInternal method in PowerManageService.java, when no audio class application plays the audio, release is carried out in a releaseWakeLockInternal in PowerManageService.java, namely the LOCK with the TAG being the AudioMix is not held any more; when the system needs to enter a sleep state, a gotoseep international method in powermanager service.
Based on the above method, it can be found that if the user is operating the android device, the trigger of the key is affirmed, the interactive keybeforedispatch method to phonewindomanager.
If the user is watching a scene behavior such as video, listening to music or having audio/video, a lock with TAG being AudioMix exists in wake_lock; if the device has entered a sleep state, execution proceeds to the gotoseep international method in powermanager service. For the three types of scenes, we can judge by setting the attribute value. For example, when the user has a key trigger, setting sys.mgtv.keyvent.time (i.e. the key trigger timestamp) to be the current system elappedrealteme (i.e. the timestamp of the duration after the system is started); when the wake_lock of the system has a lock with TAG being Audio mix (judged in acquieseWakeLockInternal), setting the attribute value of sys.mgtv.Wakelock.time (namely the audio state timestamp) to be-1, when the wake_lock of the system has no lock with TAG being Audio mix (judged in releaseWakeLockInternal), setting the attribute value of sys.mgtv.Wakelock.time to be the timestamp of the time length after the system is started, and when the play of the audio video is stopped, setting the attribute value of sys.mgtv.Wakelock.time to be elappsedRealTime of the current system (namely the timestamp of the time length after the system is started); when the system enters a sleep state (judged in the gotoseep international method in powermanager service.java), the attribute value of sys.mgtv.sleep.time is set to-1. When the value of the attribute value of sys.mgtv.sleep.time is-1, then no screen saver should be presented either.
The screen saver display method provided by the embodiment of the application is realized based on the logic, namely the screen saver display method realized based on the system function is provided, the user does not need to additionally start the application, the use experience of the user is improved, and the screen saver display method has the characteristics of simple and efficient realization process and is beneficial to assisting advertisement operation.
The following describes possible execution procedures of each step of the screen saver display method provided in the embodiment of the present application.
Optionally, as shown in fig. 2, the controlling the screen saver display state based on the current timestamp of the android system, the key trigger timestamp and the audio state timestamp includes:
s1041: when the value of the audio state time stamp is-1, returning to the step of setting a default time interval as a preset delay time length, and when the value of the audio state time stamp is a time stamp of a time length after the system is started when playing of the audio and video is stopped, acquiring the maximum values of the audio state time stamp and the key trigger time stamp as a first intermediate value;
s1042: judging whether the difference value between the current timestamp and the first intermediate value is larger than or equal to the preset delay time length, if so, sending a broadcast showing a screen saver to a desktop of the android system, returning to the step of setting the default interval time to the preset delay time length, if not, adjusting the preset delay time length according to a first preset formula, and returning to the step of judging whether the timing time of the first timer is equal to the preset delay time length;
the first preset formula includes: n=cd- (current_time-M), where N represents a value of a preset delay time after adjustment, CD represents the default time interval, current_time represents the current timestamp, and M represents the first intermediate value.
In this embodiment, by using a first timer, the method will poll at specific times whether a screen saver should be presented. When the display conditions of the screen protector are not met, restarting timing, wherein the time length of the timing is calculated according to the attribute value of sys.mgtv.keyvent.time and the attribute value of sys.mgtv.wakeup.time in the display conditions of the screen protector, and then combining a specific algorithm to ensure that the value of the time length of each occurrence of the screen protector from the moment of the condition of last allowing the display of the screen protector is the specific time (for example, the screen protector can be displayed every 10 minutes); in the scene where the screen saver is displayed, the timing duration is calculated according to the attribute value of sys.mgtv.sleep.time, so that the screen saver is hidden.
Optionally, referring to fig. 3, the screen saver display method further includes:
s105: and hiding a screen saver setting inlet when the android system does not meet the first preset condition.
The process for judging whether the android system meets the screen saver display conditions comprises the following steps:
judging whether the android system is dormant, if so, returning to the step of setting the default interval time as the preset delay time;
if not, judging whether the current desktop displays a screen saver, if so, returning to the step of setting the default interval time as the preset delay time;
if not, judging whether the current foreground application of the android system meets the display conditions, if not, returning to the step of setting the default interval time as the preset delay time, and if so, judging that the android system meets the screen saver display conditions.
The judging whether the current foreground application of the android system meets the display condition comprises the following steps:
acquiring a class name of a current foreground application of the android system;
judging whether the class name belongs to one of class names stored in a preset database, if so, judging that the current foreground application of the android system does not meet the display condition, and if not, judging that the current foreground application of the android system meets the display condition.
Specifically, whether the android system is dormant can be judged by the specific value of the attribute value of sys.mgtv.sleep.time.
The default interval time may allow the user to set through a similar interface as shown in fig. 4, assuming the default interval time is 10 minutes, a specific usage scenario is introduced as follows.
Scene one: after the system is started, a user does not perform any operation (including key press, voice and the like), at this moment, a polling timer of a screen saver starting time interval can start to display the screen saver after 10 minutes are set, before the screen saver is displayed, whether the system is dormant (if the attribute value of sys.mgtv.sleep.time is-1, the system is dormant) is judged, if the system is not dormant, the screen saver can be displayed, otherwise, the screen saver cannot be displayed;
scene II: after the system is started, a user starts playing audio/video after operating instructions such as keys or voice, in a playing scene, a polling timer at a screen saver starting time interval still works and the delay time of each time is set for 10 minutes, and a screen saver module judges whether the system is currently playing or not according to the attribute value of sys.mgtv.wakeup.time (the attribute value of sys.mgtv.wakeup.time is-1 to indicate that the system is playing); if no (sys.mgtv.wake.time attribute value is the current system elappedrealtem, i.e. the timestamp of the duration after the system is started), the preset delay duration of the first timer at this time is the interval time- (current_time-wake_lock_time) of the default screen saver, where the interval time (i.e. the default interval time) of the default screen saver is 10 minutes set by the user;
scene III: after the system is started, a user starts playing audio/video after the operation of instructions such as keys or voice, and after the audio/video playing is completed (the attribute value of the system eleasedseally realtem is the attribute value of the system eleasedsealtem), the user performs key operation (the attribute value of the system eleasedsealtem is the attribute value of the system key of the last time), and after the polling timer of the screen saver time interval reaches a timing point, the duration of the next timing is acquired again, wherein the duration is the interval time of default starting the screen saver- (current_time-key_event_time), and the interval time of default starting the screen saver is 10 minutes set by the user;
scene four: during the display process of the screen saver (the foreground process of the system is the application of the screen saver module), a polling timer defaulting to 30 seconds of the timing polling module continuously runs, when a scene of system dormancy (sys.mgtv.sleep.time with an attribute value of-1) occurs, when the first timer of the current polling reaches a delay point, the duration of the next delay point is 30- (current_time-sleep_time), and the value is certainly a value greater than 0.
Before the screen saver is displayed, it is also determined whether a special scene (such as whether a picture is currently being displayed using a file manager or other application, which is determined by acquiring a foreground process of the current system) is not allowed to be displayed in the scene.
When the user selects to close the screen saver function, the timer is correspondingly closed (namely, the timing message of the timer is removed); when the user selects other options (e.g., the set duration is 3 minutes), the first timer immediately adjusts the default polling duration to 3 minutes, the "default interval" is correspondingly adjusted to 3 minutes, and so on.
When the user has key operation behaviors, the screen saver module can immediately hide the screen saver, and meanwhile, the first timer still can continue to work.

the screen saver playing module is specifically configured to return to the step of setting a default time interval to a preset delay time when the value of the audio state timestamp is-1, and acquire the maximum value of the audio state timestamp and the key trigger timestamp as a first intermediate value when the value of the audio state timestamp is a timestamp of a time length after the system is started when the audio state timestamp is a timestamp of a time length after the audio and video are stopped;
judging whether the difference value between the current timestamp and the first intermediate value is larger than or equal to the preset delay time length, if so, sending a broadcast showing a screen saver to a desktop of the android system, returning to the step of setting the default interval time to the preset delay time length, if not, adjusting the preset delay time length according to a first preset formula, and returning to the step of judging whether the timing time of the first timer is equal to the preset delay time length;
the first preset formula includes: n=cd- (current_time-M), where N represents a value of a preset delay time after adjustment, CD represents the default time interval, current_time represents the current timestamp, and M represents the first intermediate value.
4. A system according to claim 3, further comprising:
and the hiding setting module is used for hiding the screen saver setting inlet when the android system does not meet the first preset condition.
5. A screen saver display system, comprising: a memory and a processor; wherein the memory has stored therein program code, the processor is configured to invoke the program code, the program code when invoked implementing the screen saver display method of any one of claims 1-2.
6. A storage medium having stored therein program code which when executed implements the screen saver display method of any one of claims 1-2.
