Fig. 1 is a flowchart illustrating a method for acquiring and transmitting application data according to an embodiment of the present invention.

The application scenario implemented by implementing the method for acquiring and transmitting application program data described below is an operating environment based on an Android operating system installed on a mobile terminal.

Those skilled in the art should know that the invention is proposed based on Root privilege escalation avoidance, however, the privilege escalation operation is only the privilege management control implemented by the Android system, and the invention is also applicable to the Android operating system which has Root privilege escalation.

The present invention is based on the sandbox principle and thus, one skilled in the art will understand the implementation of the present invention in conjunction with the well known sandbox implementation principle. The purpose of the sandbox is to provide a relatively closed operating environment for the target application, so that the target application accesses system resources under the security policy in the sandbox, and the activity of the target application is limited within a specified range.

It should be noted that, the present invention constructs the target application by a sandbox instance, and controls the target application to perform corresponding operation activities to obtain the relevant data of the native application. Specifically, the running activities of the target application are executed through the sandbox technology, so that the target application running in the sandbox can realize the service corresponding to the native application, and then the relevant data of the native application is acquired through the service corresponding to the native application, which can be realized by the target application execution. It is noted that the acquired data related to the native application includes data acquired only by having a high system operation authority.

Step S110: and acquiring related data of the native application program through the target application program installed in the host application program, wherein the host application program and the native application program are installed in the first terminal equipment.

The host application program is a shell application program for realizing the target application program, and the installation and the operation of the target application program can be completed through the host application program. Further, the target application needs to have the full functionality of the native application, being able to provide exactly the same services as the native application. The communication between the target application program and the sandbox running environment is established in the host application program, so that the active process of the target application program can be further monitored by the sandbox running environment, a security policy is applied to the active process, the required resources of the target application program are established in the host application program to be in one-to-one correspondence with the required resources of the native application program, the required corresponding resources of the target application program can be called in the host application program through a hook function, and the target application program can be normally loaded by the host application program and can be kept to run safely.

It should be noted that, since the data related to the native application that needs to be obtained includes data that can be obtained only by having high operating rights of the system, it is not feasible to directly obtain the data related to the native application without any processing. The scheme provided by the embodiment of the invention is that the target application program with the same functions and services as the native application program is used for executing data reading operation to obtain all relevant data of the native application program.

Optionally, the method provided in the embodiment of the present invention further includes step S130: and calling an installation package which has the same package name as the host application and is used as the attached resource of the host application in a reflection mode so as to load the target application realized by the installation package, wherein the required resource of the target application corresponds to the required resource of the native application one to one.

It should be noted that, the function of loading the target application program in the host application program may be realized through the above operation steps. However, the application can be installed and run only in a unique form in the system environment of the terminal device, that is, for an instant messaging application, only one instant messaging application can be installed and run in one terminal device, and therefore, if a target application having the same functions and services as those of the native application is installed in a system in which the native application is installed, it is not feasible to install the target application directly without any processing. According to the method provided by the embodiment of the invention, the shell adding operation is carried out on the target application program, so that the system cannot sense the existence of the target application program, and the aim of simultaneously installing the native application program and the target application program in the same system is fulfilled.

Specifically, the required resources of the target application include, but are not limited to, an Activities manager Service resource, a PackeManagerService resource, an Activity component, a Service component, a Broadcast Receiver component, a Content Provider component, and the like.

The reflection mechanism adopted by the embodiment can be a Java reflection mechanism, and all attributes and methods of any class can be known in the running state of the Java reflection mechanism; for any object, any method of the object can be called; the function of the method for dynamically acquiring information and dynamically calling the object is a reflection mechanism of JAVA language.

And calling an addAssessPath method in the AssetManager through a reflection mechanism, loading the resources in the host application program installation file into Resource, and calling the resources in the host application program installation file through a Resource object. Before obtaining the Resource of the installation file of the host application program, firstly, a DexClassLoader is newly built by the host program to load the installation package of the host application program, then, an AssetManager is newly built to load the Resource of the installation file of the host application program, and finally, the Resource of the installation file of the host application program is read through a Resource object.

Preferably, the step of loading the target application implemented by the installation package includes the step S131: a one-to-one correspondence of the required resources of the target application and the required resources of the native application is established by the host application.

For example, the operating system of the terminal device is an Android system, and the target application is App 1', which is to implement all functions and corresponding services of the native application App 1; in a host application program of the terminal equipment, an "App 1 '. apk" is an installation package with resources attached to the host application program, the installation package "App 1'. apk" is called through a Java reflection mechanism, then a target application program App1 'realized by the "App 1'. apk" is loaded, and in the process of loading the "App 1 '. apk" in the host application program, all resources required by the target application program App 1' such as an activityManagerService resource, a PackageManagerService resource, an Activity component, a Service component, a Broadcast Receiver component and a Content Provider component are created. All the required resources of the target application App 1' are in one-to-one correspondence and are the same as all the resources required by the native application to run App1 in the Android operating system of the terminal device.

More preferably, the step of establishing a one-to-one correspondence relationship between the required resources of the target application and the required resources of the native application includes steps S1311 and S1312: step S1311: analyzing the installation package to determine a resource name of the required resource of the target application program; step S1312: and loading the resources corresponding to the required resources of the native application one by one according to the resource names of the required resources of the target application.

Means for parsing the original installation package of the application program are well known to those skilled in the art. The installation package APK file is essentially a compressed package realized by combining a ZIP compression technology and a signature technology, so that on one hand, the internal file can be released through a decompression technology, and on the other hand, the internal file can be acquired through tool software such as Apktool.

Specifically, in the running process of the Android application program, a resource file packaged in an APK file is read by a resource manager called an AssetsManager. Each Activity component of an application is associated with a ContextImpl object that is used to describe the runtime context of the Activity component. The member function init of this ContextImpl object is called to perform the work of initializing the Activity component runtime context, including the work of creating resource objects and AssetsManager objects to access application Resources. Wherein, the context Impl. init function is defined in the file frames/base/core/java/android/app/context Impl. java. The parameter packageInfo in the contextimpr. init function points to a loadedApk object that describes the Apk to which the component currently being started belongs. The Resources object used to access application Resources is created by calling the parameter packageInfo to which is pointed the member function getResources of a loadedApk object. As such, application Resources may be extracted or accessed by creating resource objects.

Through the operation mode, the target application program can be loaded in the host application program for later obtaining all relevant data of the native application program through the target application program with the same functions and services as the native application program. The following will describe in detail how all relevant data of the native application is obtained by the target application.

Preferably, the step of acquiring the relevant data of the native application by the target application installed in the host application includes step S111, step S112 and step S113: step S111: calling a data reading instruction of an active process of a target application program; step S112: hooking a resource, which needs to read data, of a native application program corresponding to a resource, which needs to read data, of a target application program execution data reading instruction through a hook function; step S113: and executing the hooked resources to acquire the data related to the native application program.

First, a data read instruction of an active process of a target application is called.

Specifically, an invoking data reading instruction is actively sent through an active process of the target application.

And then, hooking the resource which needs to read the data by the native application program corresponding to the resource which needs to read the data by the data reading instruction executed by the target application program through the hook function.

It is noted that the term "hook" encompasses techniques for altering or augmenting the behavior of an operating system, application, or other software component by intercepting function calls, messages, or events passed between software components. And the code that handles such intercepted function calls, events or messages is called a hook function. Hooks are commonly used for a variety of purposes, including debugging and extending functionality. Examples of which may include intercepting keyboard or mouse events before they are passed to the application, or intercepting system calls, system function behavior, function execution results, etc., to monitor or modify the functionality of the application or other component, etc. In this embodiment, the hook function may be used to take over the installation self-checking operation required by the running of the application program.

As an example of a sandbox, a target application is operated in a sandbox operating environment, and monitoring an active process of the target application is a core implementation target of the sandbox operating environment and is responsible for implementing the following functions: by monitoring the access of the target application program to the resources, the target application program process can realize the normal calling of the corresponding resources. For example, the above-described call to the target application App 1' installation package resource can be implemented by monitoring a call instruction of a specific call resource and using a hook technology. The special service process can be registered in a mode of monitoring the active process of the target application program through the hook function, and the hook function is associated with a call instruction of the active process of the target application program App1 'to realize the activity monitoring of the target application program App 1'.

When the hook function monitors a data reading instruction of an active process calling a target application program, the hook function hooks a resource which is needed to read data of a native application program corresponding to a resource which is needed to read data of a data reading instruction executed by the target application program.

For example, the hook function is used to monitor the entry point of the data read instruction, intercept this call instruction, and obtain the name of the resource accessed by the target application App1 ', for example, the hook function obtains that the resource accessed by the target application App 1' is a Service component, and then turn to the hook function which performs the corresponding operation of hooking the resource, and the hook function hooks the Service component corresponding to the native application.

And finally, executing the hooked resources to acquire the data related to the native application program.

It should be noted that, by executing the relevant resource of the target application, the execution result identical to the execution result of the relevant resource of the native application can be achieved, and therefore, by executing the hooked resource, the target application can read the relevant data of the native application instead of the native application.

Step S120: and sending the related data of the native application program and the installation environment information of the first terminal equipment to the second terminal equipment in a preset sending mode.

Specifically, the relevant data of the native application may be acquired in the manner described above herein, and then, the installation environment information of the first terminal device is acquired; then, the data related to the native application and the installation environment information of the first terminal device are transmitted to the second terminal device by a predetermined transmission method.

Preferably, the data related to the native application includes, but is not limited to, at least one of user historical behavior data, application configuration information, and encrypted data, and the installation environment information of the first terminal device includes, but is not limited to, at least one of a CPU model number, a kernel version number, a system version number, and system configuration information. As shown in table 1, is the installation environment information of the first terminal device.

TABLE 1

It should be noted that there are various ways to send the relevant data of the native application and the installation environment information of the first terminal device to the second terminal device, for example, sending the data in a Wi-Fi hotspot, bluetooth, cloud server, and the like, and an embodiment of the present invention provides a preferred way to transmit the data, which is described as follows:

preferably, the step of sending the relevant data of the native application and the installation environment information of the first terminal device to the second terminal device in a predetermined sending manner specifically includes: and sending the related data of the native application program and the installation environment information of the first terminal equipment to the second terminal equipment through a pre-established unidirectional data link.

Specifically, by establishing a unidirectional data link between the first terminal device and the second terminal device, the problem of data leakage caused in the data transmission process by uploading data to the server can be avoided. After the data link is established, the encapsulated data is sent directly from the first terminal device to the second terminal device over the data link.

It should be noted that, data encapsulation may be performed according to characteristics of different types of data to generate different types of data packets. Each data packet carries the characteristics of the corresponding type of data, so that after the second terminal device receives the data packet, the type of the data can be known according to the characteristics of the corresponding type of data carried by each data packet.

Accordingly, after the first terminal device sends the data related to the native application and the installation environment information of the first terminal device to the second terminal device, the second terminal device locally installs and runs the secondary application based on the received data related to the native application and the installation environment information of the first terminal device.

Fig. 2 is a flowchart illustrating a method for running an application according to an embodiment of the present invention.

The application scenario implemented by the method for running the application program to be described later in the invention is a running environment based on an Android operating system installed on the mobile terminal.

The method of operation in the second terminal device is also based on the sandbox principle, so that a person skilled in the art will understand the implementation of the invention in connection with the well known sandbox implementation principle. The purpose of the sandbox is to provide a relatively closed operating environment for the target application, so that the target application accesses system resources under the security policy in the sandbox, and the activity of the target application is limited within a specified range.

Step S210: and receiving the related data of the native application program and the installation environment information of the first terminal equipment, which are sent by the first terminal equipment.

Specifically, the first terminal device sends the related data of the native application program and the installation environment information of the first terminal device to the second terminal device in a preset sending mode, and the second terminal device receives the related data of the native application program and the installation environment information of the first terminal device, which are sent by the first terminal device.

Step S220: and installing and/or running the secondary application program in the second terminal equipment based on the received related data of the primary application program and the installation environment information of the first terminal equipment.

The secondary application has all functions of the primary application, and can provide the same service as the primary application. In a specific application scenario, a user installs a native application in a first terminal device, when the user changes a new second terminal device, in the process of changing the terminal device, it is necessary to move relevant data of the native application in the first terminal device to an application corresponding to the second terminal device, where the corresponding application is a relay application, so that the relay application in the second terminal device has all functions of the native application, and under the condition that the service completely same as that of the native application can be provided, relevant data of the native application, such as a user chat record, user personal preference setting information, and the like, is also retained.

Preferably, the data related to the native application includes, but is not limited to, at least one of user historical behavior data, application configuration information, and encrypted data, and the installation environment information of the first terminal device includes, but is not limited to, at least one of a CPU model number, a kernel version number, a system version number, and system configuration information.

Preferably, the step of installing and/or running the secondary application in the second terminal device based on the received related data of the native application and the installation environment information of the first terminal device includes: step S221 and step S222: step S221: monitoring the installation and/or running activities of the secondary application through a hook function; step S222: when the fact that the secondary application program reads the installation environment information of the second terminal device and/or the related data of the secondary application is monitored through the hook function, the received installation environment information of the first terminal device and/or the received related data of the primary application program, which are in one-to-one correspondence with the installation environment information of the second terminal device and/or the related data of the secondary application, are called.

The main purpose of the above-mentioned operation steps is to create an installation and operation environment for the secondary application, in which the secondary application is not aware of being in the second terminal device, but is still considered to be in the first terminal device. In addition, through the above operation steps, the secondary application program can obtain the relevant data of the primary application program, such as the user chat record, the user operation record, the user personal preference setting information, the login verification information and the like, so that the primary application program is 'copied' from the first terminal device to the second terminal device as it is, the user can obtain the secondary application program as it is as the primary application program without performing a complicated chat record importing operation or setting the personal preference setting information for the application program again, and the user can directly log in the application program without the login verification operation.
