Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for updating a service logic of an Application program, and in particular, to a method and an apparatus for updating a service logic of an Android native Application (APP).
[ background of the invention ]
With the development of mobile internet software technology, Application programs generated by using a static compiling language, in particular, Android native Applications (APPs), become the most popular way of intelligent Application software. However, the conventional android APP update process needs to be updated in an APK package manner, so that the user experience is poor, the user cannot be forced to update, and the compatibility problem of multi-version coexistence is easily caused.
For example, after an Android APP developer issues an Android APP, the Android APP developer discovers that there is a serious bug (bug), which may affect the experience or promotion activity of the Android APP user, and thus needs to modify some business logic in the Android APP. The traditional processing flow is that the android App software needs to be subjected to code modification, recompilation and packaging, update packages are uploaded to various application markets and channels, market auditing is waited, user upgrading, user downloading and coverage installation are prompted, the series of flows are time-consuming and labor-consuming, the best update opportunity is often missed, and the users cannot be guaranteed to download and upgrade. Sometimes, only one line of code is modified, and the package is changed and the code is reissued at a great cost.
Therefore, various hot-patch dynamic repairing technical methods are proposed in the prior art later, the code execution logic is dynamically modified in a patch mode, the android App does not need to be reissued, and the problem is solved in a hot-update mode at the client.
At present, the mainstream thermal update scheme is to issue a dex file, and dynamically load the dex file by using a reflection technology to achieve the purpose of local thermal update without updating android APP, specifically including WeChat Tinker, Nuwa in a QQ space, hungry Amigo, Robust in Mei Tuo, and the like.
Due to the serious system fragmentation problem of the android mobile phone, the method for dynamically loading the dex file has the problem of adaptation of a plurality of models, so that the development adaptation workload is large, or the android mobile phone cannot normally work on certain models.
Moreover, as the Android itself has increasingly strict restrictions on interfaces such as reflection, many hot update schemes cannot be supported after 9.0 Android.
