Abstract
The invention discloses an EPG hot update system and method. The EPG hot update system comprises a JS packing system, a difference system, a version management system and an index file loading system, wherein the JS packing system comprises a JS running environment edited by JS codes, and is used for packing an index file and resource files and updating the packed index file and the packed resource files to a server; when apk is firstly packed, a default index file is generated, and the apk comprises an associated layout assembly and a path pointing a new index file; the difference system compares a local index file and local resource files with the packed index file and the packed resource files, and repeatedly packs a new added index file and resource files, thereby forming the new index file; the version management system performs version control according to version iteration; and the index file loading system controls to load and display the new index file when update is needed, which does not influence the starting speed. By utilizing the EPG hot update system and method, dynamic modification on a UI layout can be achieved.
Description
Technical field
The present invention relates to EPG more frontier, be specifically related to a kind of EPG heat and update system and method.
Background technology
Existing main flow heat updates patch framework, it is allowed to APP is the bug in repair line in the case of released version the most again.
First knowing that bug, amendment generate a patch, in the case of version number is identical, request server has patch, under will going
Carry.If version number is different, the patch of acquiescence can be deleted.Load to call by amendment internalist methodology and sequentially complete patch
Loading completes. and cardinal principle is as follows:
It is understood that the class that Java operationally loads correspondence is realized by ClassLoader, ClassLoader itself
Be one abstract come, Android uses PathClassLoader class as the Classloader of the acquiescence of Android,
What PathClassLoader realized in fact is exactly simple loading classes file from file system.PathClassLoade itself
Being inherited from BaseDexClassLoader, BaseDexClassLoader and rewritten findClass method, the method is
The core of ClassLoader.FindClass method is entrusted and is given pathList object by BaseDexClassLoader
FindClass method, pathList to as if in the constructed fuction of BaseDexClassLoader new out, its class
Type is DexPathList.DexElements list in DexPathList object is the core that class loads, and a class is such as
Fruit can be successfully loaded, then its dex is bound to occur in the dex file corresponding to dexElements, and
The order occurred in dexElements is the most critically important, and the dex above occurred at dexElements can preferentially be loaded, by adjusting
Carrying out loading classes by the loadClassBinaryName method on element.dexFile object, once Class is loaded successfully,
Will return immediately.
Realize heat renewal, it is necessary to operationally go to change PathClassLoader.pathList.dexElements,
Owing to these attributes are all private, it is therefore desirable to revised by reflection.It addition, the dex file institute constructing oneself is right
The when of the dexElements array answered, one is had to compare the mode resorted to trickery to serve oneself, it is simply that by one DexClassLoade of structure
Object loads our dex file, and calls a dexClassLoader.loadClass (dummyClassName);
Method, so, in dexClassLoader.pathList.dexElements, will comprise our dex, by handle
DexClassLoader.pathList.dexElements is inserted into system default
Before classLoader.pathList.dexElements list, it is possible to allow System Priority load the class in our dex,
Thus realize heat renewal.
Existing method deficiency is:
1. pair toggle speed slightly has an impact；
2. UI layout can not be made dynamically amendment；
3., when repeatedly patch installing, patch order may be chaotic；
4. different chip solution may need different patches.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of hot updating device of EPG and method.
The present invention is achieved through the following technical solutions:
EPG heat updates system, including:
JS packaging system, including by the JS running environment of JS written in code, be used for packing index file and resource file upload
Server, generates the index file of acquiescence when packing apk first, and described apk includes the layout component being correlated with and points to new
The path of index file；
Differential system, the local index file of contrast and the index file of resource file and packing and resource file, repack
The index file being newly added and resource file, constitute new index file；
Edition management system, carries out Version Control according to the iteration of version；
Index file loading system, when needs update, controlled loading shows new index file.
Present invention aim at breaking the primary development mode of original android, utilize js code to carry out phase as desired
Layout, the logic closed are write.Wherein, layout component includes Service Component and flexbox box model layout.JS packaging system
Js running environment is by js written in code, it is therefore an objective to the js code in parsing project, and coordinates the jar bag in we apk
The primary code of android and os file render we need display ui interface.Utilizing this device, it can be the most more
In the case of new apk file upgrading apk, the renewal/code logic including ui updates.
Reach dynamically to update, be then by the way of patch, dynamically add renewal, use this device, remain logical
Crossing apk to start normally, then reload index file, therefore toggle speed is several with the apk speed not being updated
As.
Use this device, then can carry out view and revise dynamically.Ultimate principle: java layer, passes through JavaScriptModule
Interface class definition communication means, and unify in agent intercepts class JavaScriptModuleInvocationHandler
Process all communication request being sent to Javascript.C++ layer: OnLoad is then the call entry of jni layer, have registered all of
Native method, its intrinsic call is then completed by CountableBridge.Javascript layer:
BatchedBridge is the call entry of Javascript layer, and when receiving communication request, mapping table to be first passed through confirms concrete
Solicited message, then confirm whether Javascript assembly can be called, complete to perform by apply mode the most again.
Use this device, then can carry out the iteration of version by generating the index page.Successive ignition, then from newly-generated newly
Index file, will not confusion reigned phenomenon.
Use this device, be then unified for all chip boxes, it is not necessary to the patch for certain version of having an injection, only
Need to generate index file.Apk only loads index file, and index file is then to be write by javaScript, and it is permissible
For all of chip box, therefore need not beat multiple patches.
As preferably, described edition management system is when to iteration Version Control, and request server downloads new index literary composition
Part, if failed download or decompressing files are impaired, then stop heat and updates；If current version has great bug, then change server and connect
Mouth data, do not carry out re-downloading and returning to the version of last time.
A kind of hot update method of EPG, comprises the following steps:
JS packaging system pack first apk and generate acquiescence index file；
Detection current version updates the need of heat；
If desired heat updates, JS topology file；
JS packaging system packing index file and resource file；
Index file and the resource file of packing are contrasted with local index file and resource file, repacks and be newly added
Index file and resource file, constitute new index file；
Load and show new index file.
As preferably, described JS packaging system includes by the JS running environment of JS written in code.
As preferably, described layout component includes Service Component and flexbox box model layout.
As preferably, described Service Component includes figure chip module, video component, character component, choice box assembly and drop-down
Frame assembly.
The present invention compared with prior art, at least has such advantages as and beneficial effect:
1, using the hot updating device of EPG and the method for the present invention, it is on toggle speed no impact；And can realize UI layout is moved
State is revised.
2, using the hot updating device of EPG and the method for the present invention, its patch will not be affected by chip solution, and repeatedly be beaten
During patch, patch order will not occur confusion.
