Description
Technical field
The present invention relates to electronic program guides more frontiers, and in particular to a kind of electronic program guides heat more new system and side
Method.
Background technique
Existing mainstream heat updates patch frame, allows loophole of APP in the case where not released version again in repair line.
Loophole is known first, and modification generates a patch, and in the identical situation of version number, request server has patch, under will going
It carries.If version number is different, the patch of default can be deleted.Calling sequence is loaded by modification internalist methodology to complete patch
It is as follows that cardinal principle is completed in load:
It is understood that Java loads corresponding class at runtime to be realized by ClassLoader, ClassLoader
Itself it is an abstract class, uses PathClassLoader class as the Classloader of the default of Android in Android,
What PathClassLoader was realized in fact is exactly that class file is simply loaded from file system.PathClassLoade itself
It is inherited from BaseDexClassLoader, BaseDexClassLoader has rewritten findClass method, and this method is
The core of ClassLoader.FindClass method has been entrusted to pathList object by BaseDexClassLoader
FindClass method, pathList object are that new comes out in the constructed fuction of BaseDexClassLoader, its class
Type is DexPathList.DexElements list in DexPathList object is a core of class load, and a class is such as
Fruit can be successfully loaded, then its dex is centainly appeared in dex file corresponding to dexElements, and
The sequence occurred in dexElements is also critically important, can preferentially be loaded in the dex that the front dexElements occurs, pass through tune
With the loadClassBinaryName method on element.dexFile object come loading classes, once Class is loaded success,
It will return immediately.
Realize hot update, it is necessary to remove change PathClassLoader.pathList.dexElemen at runtime
Ts, since these attributes are all private, it is therefore desirable to be modified by reflecting.In addition, constructing the dex file institute of oneself
When corresponding dexElements array, the mode for having a comparison to resort to trickery to serve oneself is exactly by construction one
DexClassLoade object loads our dex file, and calls a dexClassLoader.loadClass
(dummyClassName);Method, in this way, will include me in dexClassLoader.pathList.dexElements
Dex, by the classLoader for dexClassLoader.pathList.dexElements being inserted into system default
.pathList.dexElements before list, so that it may allow System Priority to load the class in our dex, to realize heat
It updates.
Existing method deficiency is:
1. pair starting speed slightly has an impact；
It is modified 2. cannot be laid out to UI and make dynamic；
3. patch order may be chaotic when multiple patch installing；
4. different chip solutions may need different patches.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of hot updating device of electronic program guides and method.
The present invention is achieved through the following technical solutions:
Electronic program guides heat more new system, comprising:
JS packaging system, including the JS running environment by JS written in code, for being packaged catalogue file and resource file simultaneously
Upload server generates the catalogue file of default when being packaged Android installation kit for the first time, includes correlation in the Android installation kit
Layout component and be directed toward the path of new catalogue file；
Differential system compares local directory file and resource file and the catalogue file and resource file of packing, beats again
The catalogue file and resource file being newly added are wrapped, new catalogue file is constituted；
Edition management system carries out Version Control according to the iteration of version；
Catalogue file loading system, when needing to update, the new catalogue file of control loaded and displayed.
Present invention aims at the primary development mode of original android is broken, phase is carried out as desired using js code
Layout, the logic of pass 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 for the js code in parsing project, and be cooperated in our Android installation kits
Jar packet android primary code and os file to render our need the interface ui to be shown.Utilize the present apparatus, energy
Enough to upgrade in the case where not updating Android installation package file to Android installation kit, update/code logic including ui is more
Newly.
Reach dynamic to update, is then to carry out dynamic by way of patch to add update, using the present apparatus, remains logical
Android installation kit is crossed normally to be started, then reloads catalogue file, therefore start speed and the peace without update
Zhuo installation speed packet is about the same.
Using the present apparatus, then it can carry out view and dynamically be modified.Basic principle: java layers, pass through
JavaScriptModule interface class defines communication means, and in agent intercepts class JavaScriptModuleInvocationH
It carries out that all communication requests for being sent to Javascript are uniformly processed in andler.C++ layers: OnLoad is then jni layers of calling
Entrance, has registered all native methods, and intrinsic call is completed by CountableBridge.
Javascript layers: BatchedBridge is Javascript layers of call entry, when receiving communication request, to first pass through and reflect
Firing table confirms specific solicited message, then confirms whether Javascript component can be called, finally complete by apply mode again
At execution.
Using the present apparatus, then the iteration of version can be carried out by generating catalog page.Successive ignition, then from newly-generated new
Catalogue file, will not confusion reigned phenomenon.
Using the present apparatus, then it is unification for all chip boxes, does not need the patch having an injection for some version, only
It needs to generate catalogue file.Android installation kit only loads catalogue file, and catalogue file is write by javaScript, it
All chip boxes can be directed to, therefore do not need to beat multiple patches.
Preferably, the edition management system, when to iteration Version Control, request server downloads new catalogue text
Part stops hot update if failed download or decompressing files are impaired；If current version has great loophole, change server
Interface data, without re-downloading and returning to the version of last time.
A kind of hot update method of electronic program guides, comprising the following steps:
JS packaging system is packaged Android installation kit for the first time and generates default directory file；
Whether detection current version needs hot update；
If desired heat updates, JS topology file；
JS packaging system is packaged catalogue file and resource file；
The catalogue file of packing and resource file and local catalogue file and resource file are compared, new add is repacked
The catalogue file and resource file entered, constitutes new catalogue file；
It loads and shows new catalogue file.
Preferably, the JS packaging system includes the JS running environment by JS written in code.
Preferably, the layout component includes Service Component and flexbox box model layout.
Preferably, the Service Component includes picture component, video component, character component, choice box component and drop-down
Frame component.
