The method for recovering the application data of the terminal can enable the multimedia application to automatically recover to the last playing state after the ESD restart of the terminal, improves the experience of a user, greatly reduces the hardware cost compared with the prior scheme of setting the electrostatic protector, and has wide application prospect.
In the method for restoring application data of a terminal according to an embodiment of the present invention, the step S1 of storing a temporary file generated when a multimedia application plays a media file, where the temporary file records a storage path and a playing progress of a currently played media file includes:
s1.1: the method comprises the steps of obtaining a storage path of a media file at the first time when the media file is played by a multimedia application to form a temporary file;
s1.2: copying the temporary file to a first designated directory;
s1.3: the method comprises the steps that the playing progress of the media file is obtained for multiple times according to a specified frequency from the first time when the media file is played by the multimedia application;
s1.4: and recording the acquired playing progress into a temporary file.
In step S1.1, when the multimedia application starts playing the media file, a storage path of the currently played media file is acquired, and a temporary file is formed. In this embodiment, the storage path of the media file may be acquired, and other information such as the file type of the media file may be acquired to form the temporary file.
In step S1.2, the temporary file is copied to the first designated directory. The first specified directory may be a root directory of the media file. For example, when the multimedia application plays a media file in a usb disk connected to the terminal, the first specified directory is a root directory of the currently played media file in the usb disk. The file name of the temporary file is save _ media _ info.
In steps S1.3 and S1.4, the playing progress of the media file is obtained multiple times from the first time when the media file is played by the multimedia application according to the specified frequency, and is recorded in the temporary file. For example, the playing schedule of the media file is recorded every 10s, and the frequency of recording the playing schedule is not limited by the present invention. In order to improve the user experience, the frequency of the playing progress of the recording media file is not too low, and preferably not less than once every 30 s.
In this embodiment, a storage path and a current playing progress of a media file played by a multimedia application are recorded and a temporary file is formed for storage, so that a subsequent multimedia application finds the media file played last time by reading the temporary file and continues playing from the last playing progress.
In the method for restoring application data of a terminal according to an embodiment of the present invention, step S1.4 of recording the acquired play progress in a temporary file includes:
s1.4.1: recording the currently acquired playing progress into a temporary file;
s1.4.2: and deleting the playing progress acquired last time in the temporary file.
In steps S1.4.1 and S1.4.2, the playing schedule of the media file obtained each time is recorded into the temporary file, and the playing schedule recorded last time is deleted, so that not only the size of the temporary file can be reduced, but also errors can be avoided when the later multimedia application reads the temporary file, and the playing can be continued from the playing schedule which is not recorded last time, which affects the user experience.
In the method for recovering application data of a terminal according to an embodiment of the present invention, after the abnormal restart of the terminal and before the step S2 of starting the multimedia application, the method further includes:
s1 a: monitoring an operating program of the multimedia application;
s1 b: if the running program exits due to ESD abnormality, the reset bit of the register is marked as 1;
s1 c: after the terminal is abnormally restarted, acquiring the reset bit information of the register;
s1 d: judging whether the reset bit of the register is marked as 1;
s1 e: if yes, recording the specified character string into a second specified directory.
The step S3 of determining whether the abnormal restart is an ESD restart includes:
s3.1: judging whether the second specified directory records the specified character string;
s3.2: and if so, judging that the abnormal restart of the terminal is the ESD restart.
In steps S1a and S1b, the system is equipped with a Watchdog to continuously monitor the running program of the multimedia application. If the Watchdog monitors that the program exits due to an ESD exception, the reset bit of the register is marked as 1. The principle of the watchdog Timer is applied, the watchdog Timer (WDT, Watch Dog Timer) is a component of a single chip microcomputer, the watchdog Timer is actually a counter and generally given a number, and the watchdog Timer starts counting after a program starts running. If the program runs normally, the CPU sends out an instruction to set the watchdog timer to zero after a period of time, and the counting is restarted. If the count of the watchdog timer is increased to the set value, the program is considered to be not working normally, and the whole system is forced to reset. In the present embodiment, steps S1a and S1b are completed before the terminal is restarted.
In steps S1c, S1d and S1e, when the terminal is restarted, i.e. turned on, the reset bit of the register is marked as 1, and the terminal records the specified string in the second specified directory. Specifically, in this embodiment, the second specified directory is/proc/cmdline, and the specified string is "WdtResetByEsd is 1". When the reset bit acquired from the register is marked as 1, the terminal temporarily writes a character string "WdtResetByEsd is 1" into bootargs, and after writing, a corresponding character string can be seen in the/proc/cmdline directory.
In S3.1 and S3.2, the terminal starts the multimedia application after restarting, and the multimedia application determines whether the terminal restart is an ESD restart according to whether a "wdtresetbyes" string appears under the directory/proc/cmdline. And if a character string 'WdtResetByEsd is 1' under the directory/proc/cmdlene, judging that the abnormal restart of the terminal is the ESD restart.
In this embodiment, a running program of a multimedia application is monitored through a Watchdog, when the running program exits abnormally due to ESD, the Watchdog marks a reset bit of a register to be 1, then the terminal restarts, and after the restart, a character string of "WdtResetByEsd is 1" is recorded in a directory of proc/cmdline by acquiring that the reset bit of the register is marked to be 1. After the terminal is restarted, the multimedia application which is abnormally exited is started, and whether the terminal is restarted by ESD is judged according to whether a character string 'WdtResetByEsd is 1' under the directory/proc/cmdline.
In the method for recovering application data of a terminal according to an embodiment of the present invention, after the terminal is abnormally restarted, the step S2 of starting the multimedia application includes:
s2.1: and after the terminal is abnormally restarted, sending a starting broadcast instruction to the multimedia application.
In step S2.1, after the terminal is abnormally restarted, a start-up broadcast instruction is sent, the multimedia application registers the broadcast in android manifest.xml in a static manner and receives the start-up broadcast instruction, and the multimedia application is started after receiving the start-up broadcast instruction.
In this embodiment, after the terminal is abnormally restarted, the multimedia application that was forcibly closed due to the abnormal restart of the terminal last time is started by sending a startup broadcast instruction to the multimedia application.
Further, the method for recovering application data of a terminal according to an embodiment of the present invention further includes:
s01: after the multimedia application exits, judging whether the multimedia application exits normally;
s02: if so, deleting the temporary file in the first appointed directory;
s03: if not, the temporary file under the first appointed directory is reserved.
After the temporary file generated when the multimedia application plays the multimedia file is stored in the first appointed directory, if the multimedia application exits normally, the temporary file stored in the first appointed directory is deleted immediately, so that the temporary file is prevented from occupying the storage space. If the multimedia application is abnormally exited, the temporary file stored in the first appointed directory is reserved for the subsequent multimedia application to recover the last playing state.
In the method for restoring application data of a terminal according to an embodiment of the present invention, in step S1.2 of copying a temporary file to a first specified directory, the method includes:
s1.2.1: and setting the temporary file as a hidden file.
In this embodiment, the temporary file is set as a hidden file, and the user cannot see the temporary file in the file directory, so that the temporary file can be prevented from being deleted by the user by mistake.
