Example two:
as another optional implementation manner, the method for directly installing the android application may be a method for directly installing the android application executed on an android system virtual machine in the cloud. It should be noted that, the android application in this embodiment is described by taking a game application as an example, and the method in this embodiment is not limited to a specific type of the android application.
As shown in fig. 2, the method for installing an android application in a direct manner in this embodiment includes the following steps that the cloud server (denoted as cloud game server in fig. 2) responds to a request of a user to execute the android application:
B1) receiving an android application execution request of a user;
B2) determining the android system virtual machine corresponding to the user, checking whether a target application exists in the android system virtual machine of the user, and executing the step B5 if the target application exists; otherwise, executing the next step;
B3) acquiring an installation file of a target application after pretreatment and optimization;

B5) requesting to open a target application operation to the android system virtual machine after receiving the registration result, and receiving an operation result returned by the android system virtual machine;
B6) and returning the operation result to the user who sends the request for executing the android application.
In this embodiment, the obtaining of the installation file of the target application in step B3) is specifically directed to a specified application management system to obtain the installation file of the target application, where the application management system is configured to perform preprocessing optimization and store the installation file of the target application.
As shown in fig. 3, the step of preprocessing the installation file of the optimized and stored target application by the application management system of the embodiment includes:
C1) waiting for the user to submit the android application, executing the next step if the android application is received, and otherwise continuing waiting;
C2) acquiring an original installation file of a target application;
C3) checking an application program binary interface ABI used by an original installation file of a target application, extracting all dependency libraries of the original installation file of the target application according to the used application program binary interface ABI, and storing all dependency libraries of the original installation file into a local directory of the installation file of the target application;
C4) optimizing and generating an ODEX file aiming at an original installation file of a target application, and storing the generated ODEX file into a local directory of the installation file of the target application;
C5) and performing verification check on the certificate and the abstract information of the original installation file of the target application, extracting the certificate and the abstract information into a file, storing the file into a local directory of the installation file of the target application, and finally obtaining the installation file optimized through preprocessing from the local directory of the installation file of the target application.
Referring to fig. 3, the operation of preprocessing optimization and storing the installation file of the target application is responded by the "preprocessing module" in the present embodiment, and the "preprocessing module" mainly depends on the "dependent library module", the "ODEX module", and the "certificate digest module" to complete the operation, wherein the "dependent library module" is a body module for executing step C3), the "ODEX module" is a body module for executing step C4), and the "certificate digest module" is a body module for executing step C45). In this embodiment, the "dependency library module" is implemented by customizing a pm tool and adding a processing interface "pm extra-so", and the function of the "dependency library module" is used to extract all dependency libraries in an APK file of an android application, and the interface can analyze provided parameters, forward the request to a packet management service PMS, process the request by the added interface in the packet management service PMS, and the interface checks user permissions, calculates an application program binary interface ABI (32 bit/64 bit) that should be finally used by the android application, extracts a dependency library corresponding to the application program binary interface ABI version, and stores the dependency library in a local directory for subsequent registration. The repeated installation to different mobile phones only needs to be carried out once, and the time spent on extracting the dependence library in each installation can be saved.
In this embodiment, the "ODEX module" is implemented by customizing a pm tool and a newly added processing interface "pm gen-dex", and the "ODEX module" is used to perform ODEX optimization. The ODEX module can analyze the provided parameters, forward the request to a newly added interface of the PMS, the PMS interface can check the execution authority, calculate the application program binary interface ABI finally used by the APK, and then call a system tool dex2oat to perform optimization processing, and after the processing is finished, the generated ODEX file is stored in a local directory for a subsequent registration mechanism to use. The method has the advantages that the method can be repeatedly installed on different mobile phones only by once optimizing and acquiring the corresponding ODEX file, so that the required ODEX file can be extracted, the application can run efficiently, and meanwhile, the processing efficiency is higher than that of the scheduling optimization of system services in other schemes due to active optimization; whether the optimization is carried out can be determined according to needs, and the optimization is relatively more flexible.
In this embodiment, the "certificate digest module" is implemented by customizing a pm tool and a newly added processing interface "pm extra-crt", and the "certificate digest module" is used to verify certificate information of an apk package of an android application, extract digest information of an installation package, check an operation permission problem, and the like. The certificate abstract module can execute the same Android official check on the certificate and abstract information of the specified installation package according to the provided installation package path, and meanwhile extracts the certificate and the abstract information to a file to be stored in a local environment for subsequent registration and use. The repeated installation of different mobile phones only needs to be executed once, the certificate and the summary file which fall to the ground are handed to subsequent installation for use, the operation of the part takes several minutes or more in the ordinary installation of plain elite, and the time consumption can be almost ignored after the optimization.
It should be noted that the manner in which the "preprocessing module" and the "preprocessing module" mainly depend on the "dependency library module", "ODEX module", and "certificate digest module" to complete operations is only one specific implementation manner of the application management system in this embodiment to optimize preprocessing and store the installation file of the target application. Needless to say, in light of the above specific implementation manner, a person skilled in the art may also use more or fewer functional modules as needed, and also may implement the operation of preprocessing optimization of the application management system and storing the installation file of the target application in this embodiment, which is not described herein again.
