Class conflicts after putting dex files together

[xihan123]

Code here

Why Count the number of dex files and rename classes.dex correctly.

I have found that in some cases, if the apk has too many dex, the introduced modules may not work

Such as wechat、QQ、DingDing

Could you provide more concrete proof that it is this commit that causes the failure of hooks?

That commit was intended to give compatible support for Chrome browser.

[xihan123]

It is not that the hook fails, but that in the case of too many dex, such as 26 dex, the module is not effective because it is not able to execute that part at all

[xihan123]

After testing, it did solve the problem, but why not use the original solution, which is to reduce the number of dex and do not need to change the Lsposed core

[JingMatrix]

I explained it at the beginning, it is intended to support Chromium browsers.

[JingMatrix]

In the future, I may add some codes to smartly choose different ways of patching the code.

[xihan123]

I explained it at the beginning, it is intended to support Chromium browsers.

Because I don't understand what support is Chromium browsers

I found a new problem

If the class used in the module does not exist in the original dex

An error may be reported at runtime
log:Crash unexpectedly: cn.hutool.crypto.CryptoException: NoSuchAlgorithmException: class configured for MessageDigest (provider: BC) cannot be found.

pecific trigger:
hutool is not referenced in the source apk
The module references hutool
An error was reported while starting the application

I can write a minimal example if I need to

[xihan123]

Which brings us back to where we started

Any source dex that does not include the class referenced in the module will cause an exception that the class does not exist as usual during development

[xihan123]

Before this submission the patch was normal

Please capture your logs containing this problem using:

adb logcat -s AndroidRuntime LSPatch LSPosed LSPatch-MetaLoader LSPatch-SigBypass LSPosed-Bridge LSPlant LSPosedContext zygisk64 LSPlt Dobby LSPosedService '*:F' > log.txt

then upload the log.txt file.
