Based on the hardware structure, the embodiment of the system attribute monitoring method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a system attribute monitoring method according to a first embodiment of the present invention.
In a first embodiment, the system attribute monitoring method includes the following steps:
s10: when system attribute setting is carried out on a layer C of an android system, transmitting attribute information of the system attribute to a JAVA layer of the android system;
it should be noted that, in the android system, the system attribute may be set by JAVA, C + +, C, and using a shell command, but these operations are all finally set by a send _ prop _ msg function of the C layer, where the send _ prop _ msg function is completed by sending the attribute to be set to the attribute server of the C layer using a socket, and therefore, when the system attribute is set by the send _ prop _ msg function of the C layer, the attribute information of the system attribute may be transmitted to the JAVA layer of the android system.
Since the layer C and the JAVA layer in the android system belong to different framework layers, in order to facilitate communication between the layer C and the JAVA layer, in this embodiment, the attribute information of the system attribute may be transmitted to the JAVA layer of the android system through a JAVA Native Interface (JNI) mechanism.
It is understood that the C layer may call to JAVA layer functions through a JNI mechanism, or the JAVA layer may call to C layer functions through a JNI mechanism.
In a specific implementation, in order to facilitate transmission of the attribute information of the system attribute to the JAVA layer of the android system through a JNI mechanism, in this embodiment, when the system attribute is set on the C layer of the android system, the attribute information can be called as a parameter to a preset program segment of the JAVA layer of the android system by a preset function of the C layer of the android system through the JNI mechanism, so as to transmit the attribute information of the system attribute to the JAVA layer of the android system.
In order to enable the preset program segment to perform attribute processing, in this embodiment, the preset program segment belongs to a systemoproperties class of a JAVA layer of the android system, and certainly, the preset program segment does not belong to an existing program segment in the systemoproperties class of the JAVA layer, but is established according to needs in this embodiment, and in order to facilitate identification thereof, in this embodiment, a name of the preset program segment may be set to getsystemoprocenge, so that the preset function is called conveniently.
S20: generating data to be broadcasted in a JAVA layer of the android system according to the attribute information;
it should be noted that after the attribute information is obtained, the data to be broadcasted that can reflect the attribute information can be generated.
S30: and broadcasting the data to be broadcasted in a JAVA layer of the android system, so that a broadcast receiver sends the data to be broadcasted to a target application program after monitoring the data to be broadcasted.
In a specific implementation, the target application may be one application or multiple applications, which is not limited in this embodiment.
In this embodiment, when system attribute setting is performed on the layer C of the android system, the attribute information of the system attribute is transmitted to the JAVA layer of the android system, then data to be broadcast is generated in the JAVA layer of the android system according to the attribute information, and finally the data to be broadcast is broadcast in the JAVA layer of the android system, so that a broadcast receiver sends the data to be broadcast to a target application program after monitoring the data to be broadcast, thereby simply and timely enabling the target application program to implement system attribute monitoring without affecting normal operation of a general system platform application, and improving program performance.
Further, as shown in fig. 3, a second embodiment of the system attribute monitoring method according to the present invention is provided based on the first embodiment, and in this embodiment, before step S10, the system attribute monitoring method further includes:
s01: receiving a registration instruction sent by a target application program to a broadcast receiver in a JAVA layer of the android system;
s02: and the broadcast receiver monitors and registers according to the registration instruction so as to monitor the data to be broadcast.
It should be noted that, in order to enable the broadcast receiver to determine the target application program that needs to monitor the system attribute, a registration instruction sent by the target application program to the broadcast receiver may be received in the JAVA layer of the android system, and then the broadcast receiver performs monitoring registration according to the registration instruction, so that the target application program can monitor the data to be broadcast through the broadcast receiver.
It can be understood that the onReceive function can be rewritten by the target application program after sending the registration instruction to the broadcast receiver, so that after receiving the data to be broadcast sent by the broadcast receiver, the service logic processing is performed according to the data to be broadcast.
In order to facilitate the listening registration of the target application, in this embodiment, the attribute information may include: a target attribute name prop _ name and a target attribute value prop _ value;
correspondingly, the step S20 may specifically include: generating data to be broadcasted in a JAVA layer of the android system according to the target attribute name prop _ name and the target attribute value prop _ value, wherein the data name of the data to be broadcasted is generated according to the target attribute name prop _ name, and the data content of the data to be broadcasted is the target attribute value prop _ value;
correspondingly, the step S02 may specifically include: and the broadcast receiver extracts the attribute name to be monitored, which is the same as the target attribute name prop _ name, from the registration instruction, generates a name of data to be monitored according to the attribute name to be monitored, and monitors and registers the name of the data to be monitored so as to monitor the data to be broadcast.
In this embodiment, since the data content of the data to be broadcasted is the target attribute value prop _ value, the target attribute value can be obtained after the target application program obtains the data to be broadcasted, so as to know the setting condition of the system attribute.
Since the data name of the data to be broadcasted is generated according to the target attribute name prop _ name, and the data name to be monitored is generated according to the attribute name to be monitored which is the same as the target attribute name prop _ name, the broadcast receiver can monitor the data to be broadcasted by the data name to be monitored.
It can be understood that, in a specific implementation, since the target attribute name prop _ name may be the same as other attribute names in the android system, confusion is likely to occur, so as to cause misidentification of an application program.
In order to prevent the generation process of the data name of the data to be broadcasted and the data name to be monitored from being too complex, in this embodiment, the data name of the data to be broadcasted is obtained by splicing a preset character string and the target attribute name, and correspondingly, the attribute name to be monitored also needs to be obtained by splicing the preset character string and the attribute name to be monitored, that is, the preset character string and the attribute name to be monitored are spliced to obtain the data name to be monitored.
Assuming that the target attribute name is "persistence. system. language", and the preset character string is "com.tc.sysprep. change", at this time, the data name of the data to be broadcasted may be "com.tc.sysprep. change. persistence. system. language", and accordingly, the attribute name to be listened is also "com.tc.sysprep. change. persistence. system. language".
In a specific implementation, the data type of the data to be broadcasted may be an Intent type, and correspondingly, the data to be listened to registered in the broadcast receiver may be an Intent filter type.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, where a system attribute monitor is stored on the computer-readable storage medium, and when executed by a processor, the system attribute monitor implements the following operations:
when system attribute setting is carried out on a layer C of an android system, transmitting attribute information of the system attribute to a JAVA layer of the android system;
