After turning on the default R8 obfuscation, the wrong effect is produced

Android Version 14
ApkTools Version : apktool_2.10.0.jar
Ndk Version : 23.0.7599858
Apk isMinifyEnabled = true

// dcc.py config
current_dir = os.path.dirname(os.path.abspath(__file__))
APKTOOL = os.path.join(current_dir, 'tools', 'apktool.jar')
APKTOOL2 = os.path.join(current_dir, 'tools', 'apktool.bat')
APKTOOL3 = os.path.join(current_dir, 'tools', 'apktool')
SIGNJAR = os.path.join(current_dir, 'tools', 'apksigner.jar')
MANIFEST_EDITOR = os.path.join(current_dir, 'tools', 'manifest-editor.jar')
NDKBUILD = "ndk-build"

Use the default obfuscation configuration without any changes and install app-release.apk to run normally
Then the following is the preparation work before dex2c configuration, and some code is posted
```
// config fillter.txt
com/example/testproject/MainActivity;getResources\(.*
```

// MainActivity Source Code
package com.example.testproject

class MainActivity : AppCompatActivity() {

    val binding by lazy { ActivityMainBinding.inflate(layoutInflater) }

           if (widthPixels > heightPixels) {

Even without obfuscating getResource, when I changed it to printHelloWorld, after running the command line, it prompted No methods compiled! “Check your filter file.” So I found the obfuscated printHelloWorld, as follows

Modify the filtering rule to: h1/AbstractC0290a;a\(.*

When I run the dex2c command again, I still get the following message: “Check your filter file.”

And when I confuse the onCreate method, it still throws the same exception as above. Is it impossible to confuse resources after using dex2c? Is the code obfuscated?

Hello @crowforkotlin, thank you for providing detailed information.

However, I am unable to reproduce the issue following the information provided.

The recommended NDK version should be between r25b and r27b, with r26b being the most preferred.

No, you can confuse resources even after applying dex2c, see out_obf_res.zip

Is it impossible to confuse resources after using dex2c?使用 dex2c 后不可能混淆资源吗？

No, you can confuse resources even after applying dex2c, see不可以，即使在应用 dex2c 后，您也可能混淆资源，请参阅 out_obf_res.zip

1. I followed your steps step by step and finally generated the product. In addition, I tried to replace android.debug.keystore with jks of my own project. After modifying the signature file twice, the product apk installation failed and crashed directly. The error message was still the same as above, that is, the resource could not be found.

Caused by: android.content.res.Resources$NotFoundException: Drawable com.example.testprojeect:drawable/abc_vector_test with resource ID #0x7f070077 Caused by: android.content.res.Resources$NotFoundException: File res/hq.xml from drawable resource ID #0x7f070077

This is my final configuration file

}

1. In addition, I also encountered an error when running dex2c after replacing keystore with jks, prompting Algorithm HmacPBESHA256 not available. The solution is to set jdk17 as the preferred environment variable.
1. This is the problematic warehouse. The apk is in app/release and has been packaged. I just don't know why this problem occurs. If you have time, please take a look. Thank you!

For now, you can sign the output APK (which will initially be signed with debug keystores) using your custom keystore after you've completed the dex2c processing on the APK.

I've tried checking it and it's fine at my side yet again, maybe it's an issue with windows side (?) I'll try checking on windows in a while to confirm things.

Edit: can't repro

Built from https://github.com/crowforkotlin/Dex2c-TestProject then performed dcc on getResources. Tested working fine on A14. I guess the issue has nothing to do with r8 minification.

Is this problem unrelated to r8? If I turn off obfuscation, everything will return to normal, but when obfuscation is turned on, the above problem will occur

@crowforkotlin Neither @Kirlif nor I have been able to reproduce the issue with the APK you provided, or by building from source ourselves. Therefore, I've closed the issue for now. If you're able to identify the cause or provide clear, reproducible steps, or if someone else encounters the same issue, we'll revisit it.

Is this problem unrelated to r8? If I turn off obfuscation, everything will return to normal, but when obfuscation is turned on, the above problem will occur

This does not imply that the problem is with r8. Please, test this: Test.zip

This does not imply that the problem is with r8.这并不意味着问题出在 r8 上。 Please, test this: 请测试一下： Test.zip

I installed it and it's normal! Could you please send me the system environment, SDK NDK, APKTOOL and other configurations for running dcc? I'll try it tomorrow

I used the original signature test.jks of this project to package, and directly used the generated apk in app/release/app-release.apk https://github.com/crowforkotlin/Dex2c-TestProject/blob/main/app/release/app-release.apk
Here, the original signature test.jks is also configured for dex2c
The next steps are the same as in the video. First, I installed app-release.apk normally, but when I entered the next step dcc and continued to install output.apk, it crashed.

you can download apk check it apk.zip

The decompiled code of output.apk looks fine, but when I launch the app it crashes.

Hi @crowforkotlin,

I noticed in your video that you're using outdated code, as the API level being returned is still 28. With the recent updates, it should be returning 34. I recommend doing a git pull to fetch the latest changes and update your project accordingly.

Also, please refrain from editing dcc.py as no modifications are necessary for that file.

OK, I'll try again. Actually, I don't want to modify dcc.py, but if I don't modify it, I will be prompted with this long list of commands when using dcc on Windows, so I refer to #13

Okay, it makes sense now. The issue was closed, which is why it slipped our attention. It appears to be a Windows-related problem that needs resolution. Thank you for bringing it to our attention.

I use the latest master branch code, and the configuration is exactly the same as above, and now DCC fails

Yes, I've started up my Windows and can now replicate the issue, which is why I've reopened it. This appears to be an issue on the Windows side; for now, you can use WSL on Windows until it is resolved. Thank you.

@crowforkotlin, implemented a fix on the fix/windows branch. To clone it, use git clone https://github.com/codehasan/dex2c.git -b fix/windows. Everything is working perfectly on my end now; please try it and let me know.
