看了代码，有一个test方法，拿一个空项目按照代码设置文件夹和new.pat

执行结果报错

手工热更新测试错误，希望大佬指点我一下。大佬能加一下Q吗？2229713767

执行 doHot(baseApk,baseSoDir,hotApk,hotSoDir);就报错了，可是so库都是在release中下载的，然后直接导入的jniLibs目录文件下

java.lang.UnsatisfiedLinkError: No implementation found for void com.unity3d.update.HotUnity.doHot(java.lang.String, java.lang.String, java.lang.String, java.lang.String) (tried Java_com_unity3d_update_HotUnity_doHot and Java_com_unity3d_update_HotUnity_doHot__Ljava_lang_String_2Ljava_lang_String_2Ljava_lang_String_2Ljava_lang_String_2)

il2cpp model on all Android 4 have this risk；

baseapkPath or libPath need end with '\0' or '/ ' when mapPath

need add to clear cache step function before rebootApp

yes, suport it as zip file by ApkDiffPatch;

same: can't read /data/user/0/<appid>/files/
(API 24,28 ok)

libunity.so是否有路径校验。我现在hook映射已经成功了，但是仍加载不出来。在Loading player data之后就报错了

将libil2cpp.so 放入update.apk_lib中, 重启后提示 Error : Failed to load Il2CPP.

need ApkDiffPatch adding API for this;

set .so files 0755

支持更新libunity.so?
这个更新so是否具有广泛性?跟unity无关的一些ndk编译的动态库也可以更新吗?(程序逻辑来保证更新结束加载so)
跟商店(国内国外)规则会不会有冲突?

第一步找这个文件，但是项目里没看到，这是动态生成的吗

english and 中文

now only check: UnityLib is changed?
todo: other check?

hook to new.apk and new .so

now, no SD card for test

auto loaded libmain.so when new UnityPlayer()，so can't hot update it.
code is：

    static {
        (new m()).a();
        s = false;
        s = loadLibraryStatic("main");
    }  

edit file unity-classes.jar!/com/unity3d/player/UnityPlayer.class ,
change "main" to "null" , and add libnull.so file in project libs;
( "main" is only used here, so edit is safe; )

请问如果有多个补丁包的话，这种情况该如何处理，我尝试了用不同的补丁包连续调用两次apkPatch，第二次调用的时候返回的不是0，是否有方法能一次更新完多个补丁包，而不用重启多次，或者能在本地将多个补丁包合成一个，再调用apkPatch

/data/data/appid/files can get it's path?

test it's ok!

found fail dlopen libil2cpp.so!

fix it by preload new libil2cpp.so

hook all .so by libunity dlopen

used unity2017.4

crash after re dlopen libunity.so, test on simulator;
before this，have a another crash:
crash after open("/storage/sdcard/Android/data/<app id>/files/il2cpp/SymbolMap-ARM64",577) (test remove ARM64 lib is have same crash)

iqiyi的xhook库不支持android11，这个有方法解决么
