Limitations of the Android Andfix repair method

Here read a lot of online information about the repair, one by one posted here for easy viewing:

Here are a few ways to fix it:

Andfix Repair:

① does not support YunOS
② Unable to add new class and new field
③ needs to use the pre-hardening apk to make patches, but the patch file is easily decompile, that is, the modified class source is easy to leak.
④ using a hardened platform may invalidate the hot patch function (see someone in the 360 reinforcement that raised the issue, not yet verified by yourself).

⑤andfix does not support modification of layout resources, etc.

⑥ Official website: Andfix supports Android version from 2.3 to 7.0, both ARM and X86 architecture, both Dalvik and ART runtime, both 32b it and 64bit.

⑦ application patches do not require a restart. However, because the initialization of the class is skipped directly from the implementation, the initialization is complete, so there is a problem with the static function, the static member, the constructor, and the class class.forname of the complex point will probably hang up directly.

A potential problem with ⑧andfix:

Once the patch is loaded, the Out.apatch file is copied to the/apatch folder in the Getfilesdir directory, and the next patch update detects if the patch has been added to the Apatch folder. Out.apatch that loaded sdcard will not be copied if it already exists.

Source:

 Public voidAddpatch (String Path)throwsIOException {File src =NewFile (path); File dest=NewFile (Mpatchdir, Src.getname ()); if(!src.exists ()) {
 　　　　 Throw Newfilenotfoundexception (path); }
　　 if(Dest.exists ()) {
LOG.D (TAG, "patch [" + Path + "] have be loaded."); return; }
Fileutil.copyfile (SRC, dest);//copy to patch ' s directoryPatch patch =Addpatch (dest); if(Patch! =NULL) {
Loadpatch (patch); }
}
