Part.Four big components include: component activity Activity, service Service, broadcasting receiver BroadcastReceiver, content
Provider ContentProvider.
Therefore by Manifest.xml configuration file, the starting information of system all components can be extracted.
Since the starting of each component has explicit starting and implicitly starting two ways, according to explicit starting and implicitly
Start two ways, extracts starting information.
In the present embodiment, in extraction system each component starting information, formation component list, comprising:
Each module information explicitly started in extraction system generates explicit starting the component list；
Each module information implicitly started in extraction system generates implicit starting the component list.
Further, each module information explicitly started in extraction system generates explicit starting the component list, concrete mode
Are as follows:
Each component containing .class field is searched for, and extracts each module information containing .class field, is generated explicit
Start the component list, the list includes each component Name and corresponding .class field.
Further, each module information implicitly started in extraction system generates implicit starting the component list, concrete mode
Are as follows:
Each component containing .action field is searched for, and extracts each module information containing .action field, is generated hidden
Formula starts the component list, and the list includes each component Name and corresponding .action field.
As shown in Figure 5 A and 5B, respectively Activity implicitly starts the component list and Service implicitly starts column of assemblies
Table.Implicit starting the component list stores each component Name implicitly started and corresponding .action field.Other types group
The component list of part is similar with Activity and Service, does not do describe one by one here.
Similarly, explicitly starting the component list stores each component Name explicitly started and corresponding .class field.
Here it does not repeat them here yet.
Step 402, according to the component list, construct and inter-related have been turned on component search tree.
Referring to Fig. 6, having been turned on the flow chart of component search tree for building.As shown in figure 5, according to starting information list,
Construct it is inter-related have been turned on component search tree, specifically include:
Step 601 finds the first starting component, the root node as search tree by manifest.xml.
In general, it is Activity1 that android system first, which starts component, using the first starting component as the root of search tree
Node will be directly linked with the first starting component or other starting components of indirect association be as leaf node, and generation has been opened
Dynamic component search tree.
Step 602 searches for whether have other starting components in explicitly starting the component list and implicit starting the component list
Reference the first starting component, if it is, establishing the association of the first starting component to the starting component.
In the present embodiment, specifically in the following way:
Whether search in the java file of the first starting component has other assemblies in explicit starting the component list
.class field, if it is, the association of the first starting component to the starting component is established, if it is not, then whether search has
The .action field of other assemblies in implicit starting the component list, if there is implicitly starting other assemblies in the component list
.action field then establishes the association of the first starting component to the starting component.
Step 603 searches for whether have other starting components in explicitly starting the component list and implicit starting the component list
The reference component associated with the first starting component, is arrived if it is, establishing component associated with the first starting component
The association of the starting component, until generating using the first starting component as the search tree of root node.
Whether search in the java file of component associated with the first starting component has in explicit starting the component list
The .class field of other assemblies, if it is not, then whether search has the .action word of other assemblies in implicit starting the component list
Section.
It being exemplified below and has been turned on component search tree construction, it is assumed that Activity1 is root node, Activity2,
Activity3, Activity4, Service1 are the child node of Activity1, and Activity5, Activity6 are
The child node of Activity4.
Step 403, the successively resource file in search system application program under each catalogue.
Usually, RES file is referred to as resource file, therefore successively searches for RES mesh in android system application program
Resource file under record.Such as gerFiles function recursive search RES catalogue can be called, obtain all resources under the catalogue
File.Which is not described herein again.
Whether step 404 detects resource file by any component in described search tree in having been turned on component search tree
It directly or indirectly quotes, if it is, retaining using the resource file as effective document, if it is not, then will be described
Resource file is deleted as garbage files.
In another feasible scheme, before executing step 404, following steps are first carried out:
Resource file is detected whether cited in any file of system, if it is not, then using the resource file as rubbish
File is deleted, if it is, further detecting whether resource file is had been turned on by described in having been turned on component search tree
Any component in component search tree is directly or indirectly quoted.
Specifically, by recursive lookup, searched in having been turned on component search tree resource file whether with search tree species
Any component has directly or indirectly adduction relationship.
Assuming that resource file A is quoted by file B, file B is quoted by file C again, then file A is directly to quote with file B
Relationship, file A and file C are indirect referencing relationships.
For example, detecting that resource file A is quoted by another file B of system, need further to detect, whether file B is by it
Cited in his file, that is, whether file A there are also other indirect referencing files, when resource file A direct reference document B or
Other indirect referencing files of person are then to determine resource file A for efficient resource when having been turned on any component in component search tree
File, when recursive traversal has been turned on all components in component search tree, the direct reference document B of resource file A or other
Connecing reference document is not then to determine that resource file A is invalid waste resources when having been turned on any component in component search tree
File carries out delete processing.
The method of invalid resource in deletion Android system provided in this embodiment, when detecting resource file by alternative document
When reference, component search tree is had been turned on by building, the validity of reference document is further retrieved, it is ensured that the resource file
Validity fundamentally solve in application program and provide in vain to delete invalid waste resources file to the greatest extent
Source occupies the problem of system partitioning.
Referring to Fig. 7, Fig. 7 is another method for deleting invalid resource in Android system provided in an embodiment of the present invention
Flow chart of steps, which comprises
Step 701, by Manifest.xml configuration file, each module information for explicitly starting in extraction system and implicit
Each module information of starting, it is corresponding to generate explicit starting the component list and implicit starting the component list.
In a feasible scheme, each module information explicitly started in extraction system generates explicit starting column of assemblies
Table, concrete mode are as follows:
Each component containing .class field is searched for, and extracts each module information containing .class field, is generated explicit
Start the component list, the list includes each component Name and corresponding .class field.
Each module information implicitly started in extraction system generates implicit starting the component list, concrete mode are as follows:
Each component containing .action field is searched for, and extracts each module information containing .action field, is generated hidden
