The technical solution of patch, modification class initial phase load patch, so there is no need in startup stage by all patch
Class instantiation, also there is no need to initialize all classes modified in startup stage, but is modified using for the first time
Class before, complete the load of patch.During realization, one class of addition in sdk can be answered in hot repair first
ClinitInterceptorStorage, wherein only including a static variable ClinitInterceptable. $ ic.Class is initial
Change method blocker is just stored in ClinitInterceptorStorage. $ ic.Then, hot repair is needed when modification occurs for class
When multiple, class all in the installation kit of old edition and the installation kit of new version is subjected to differential ratio pair, obtains the class of all modifications.Tool
Body, while generating patch, all classes in new and old apk are compared, have class initialization in case of the class of modification
Method<clinit>, then being marked as its patch class can delay loading.After completing the comparison of all classes, if there is be marked as can
The patch class of delay loading, then one class initial method blocker of creation, that is, create one
The subclass of ClinitInterceptable class, in the method invokeClinit method of this subclass, the judgement of addition branch,
If the caller for calling this method is the class A modified, the corresponding patch class of class A is created, and by its assignment into A
Static variable in.Similarly, for other classes modified, same branch's decision logic can also be added, to realize
All patch that modification class occurs.Then, the class initial method blocker of creation is also put into patch.In project initiation
When, extra process is not needed, is started by normal flow.But in some class for the first time in use, if a class has initialization side
Method<clinit>, then it is different from conventional method to the pitching pile of<clinit>method, it judges wherein
ClinitInterceptorStorage. whether $ ic is sky, that is, judges whether there is class initial method blocker.Then, if
ClinitInterceptorStorage. $ ic is sky, that is, class initial method blocker is not present, does not deposit then can determine
It in patch, that is, does not need hot repair and answers, then execute method original in class, class can be initialized according to normal flow.If
ClinitInterceptorStorage. $ ic is not empty, i.e., and determines that there are class initial method blockers.At this point it is possible to adjust
With the method invokeClinit in class initial method blocker ClinitInterceptorStorage. $ ic, i.e.,
ClinitInterceptorStorage.$ic.invokeClinit.Method in class initial method blocker
InvokeClinit, for detecting whether caller is the class modified；If the class of modification, then Patch example is created, completed
The load of Patch, to complete in patch to the restorative procedure of class initial method<clinit>.Therefore, multiple entire of hot repair
Process is exactly, and when project initiation normally starts, when the class A modified is initialised, can call the initial method of class A <
Clinit >, at this moment since class initial method blocker ClinitInterceptorStorage. $ ic is not sky, can call
ClinitInterceptorStorage. $ ic.invokeClinit method finds caller in invokeClinit method
For the class A modified, the corresponding patch class example of class A, and the static variable being assigned in class A will create, complete class
The load of the corresponding patch of A.Similarly, other classes modified, also can the corresponding patch class reality of loading classes in initialization
Example.Finally, after the load for completing Patch, further includes: if there are restorative procedures in Patch, execute restorative procedure；If
Restorative procedure is not present in Patch, then executes method original in class.For example, being deposited in the corresponding patch of class A modified
In restorative procedure, then restorative procedure is executed after load, so that it is multiple to realize hot repair.
It does not need to instantiate all Patch classes in startup stage using the above method, not need in startup stage yet
The class of all modifications is initialized, so that influence of the Patch load to application starting speed is effectively reduced, so that the starting of application
Faster, user experience is good for speed.

Judgement creates the corresponding patch class of class A if the caller for calling this method is the class A modified, and by its assignment
In static variable into A.Similarly, for other classes modified, same branch's decision logic can also be added, thus
Realize all patch loads that modification class occurs.Therefore, the multiple whole process of hot repair is exactly, and when project initiation normally starts, when
When the class A modified is initialised, the initial method<clinit>of class A can be called, at this moment since class initial method blocks
Cutting device ClinitInterceptorStorage. $ ic is not sky, can call ClinitInterceptorStorage. $
Ic.invokeClinit method finds that caller is the class A modified in invokeClinit method, will create A pairs of class
The patch class example answered, and the static variable being assigned in class A complete the load of the corresponding patch of class A.Similarly,
The class that he modifies, also can the corresponding patch class example of loading classes in initialization.
Optionally, after the load for completing Patch, further includes: if there are restorative procedures in Patch, execute reparation
Method；If restorative procedure is not present in Patch, method original in class is executed.For example, the class A modified is corresponding
There are restorative procedures in patch, then restorative procedure is executed after load, so that it is multiple to realize hot repair.
S103, if it does not exist class initial method blocker, then execute method original in class.
In the present embodiment, if ClinitInterceptorStorage. $ ic is sky, i.e., blocked there is no class initial method
Device is cut, then can determine that there is no patch, that is, hot repair is not needed and answers, then execute method original in class, it can be according to normal
Process initializes class.
The present embodiment, by when class initializes, judging in class with the presence or absence of class initial method blocker；Class if it exists
Initial method blocker then executes the method in class initial method blocker；Class initial method blocker if it does not exist,
Then execute method original in class.The present invention does not need to instantiate all Patch classes in startup stage, does not need yet
Startup stage initializes the class of all modifications, so that influence of the Patch load to application starting speed is effectively reduced, so that answering
