Now, I think how to resole this question.
Thanks

Now, I think how to resole this question.

@janecms do you want to prepare a PR for that issue? PR is always welcome 🙂
Anyway, it will be nice to provide a sample, so we can reproduce/check this issue.

how to resole??

jpstotz · 2022-11-24T08:15:11Z

@sulab999 @janecms The best way to resolve an issue that is caused by a certain DEX/APK files is providing the APK file.

@janecms In your original post you wrote Now, I think how to resole this question. Most people would interpret this sentence this way "I think now I know what changes needed to be done in Jadx to resolve this issue in Jadx". Thus skyot proposed to you to open a PR. If this sentence was meant in a different way please tell it to us.

Hey there! any updates about this?

skylot · 2024-03-02T18:20:05Z

@ya121y we still do not have sample to reproduce this issue.
Sample provided by @sulab999 not having this exact issue (checked with latest unstable build).

@ya121y if you can share a sample please open a new issue, I will close this one because it is old and useless now.

I know this was closed for lack of info but am getting it with the coospo CoospoRide app (current app com.onecoder.coosporide v2.5.31 does as well as prior versions). Was trying to figure out how it talks to my ble hardware but nothing gets decoded. App can be had off the Play store or from apkpure https://apkpure.com/coosporide/com.onecoder.coosporide

One example error message from one of the fragment classes, but this seems to happen with pretty much all the classes.

@draekko Thanks for providing a sample app. Which Jadx version have you used when the posted error occurred?

I wasn't able to reproduce your problem using Jadx 1.5.0 and also not with latest stable version decompiling androidx.fragment.app.Fragment of CoospoRide_2.5.31_APKPure.apk (SHA-1 hash 9F8D9CFED84E2514EBE644235B289E26A914C41D).

draekko · 2024-09-11T12:52:08Z

I tried 1.5.0 release which i've been using since it was released and tried the latest unstable build this morning.

Java says this

openjdk 21.0.4 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode, sharing)

Using it on latest Ubuntu 24.04.1 LTS

draekko · 2024-09-11T12:54:56Z

hmmm seems to have a different hash as the one i extracted off the device which i got it via the play store using aurora store for v2.5.31.

Does jadx use JAVA_HOME or does it use the default path for the jdk?

Edit: nevermind i figured out it does :)

I just tried 11, 17, and 21 for openjdk java version, same results.

jpstotz · 2024-09-11T13:11:36Z

Verified - com.onecoder.coosporide.main.ChartFragment causes multiple errors like java.lang.IllegalArgumentException: newPosition > limit: (67042709 > 8843904) in APK CoospoRide_2.5.31_APKPure.apk (SHA-1 hash 9F8D9CFED84E2514EBE644235B289E26A914C41D) from https://apkpure.com/coosporide/com.onecoder.coosporide

Tested with latest unstable Jadx-gui version.

draekko · 2024-09-11T14:58:24Z

As far as i can tell all the classes under com.onecoder.coosporide.* seem to be having the issue.

jackwpa · 2024-09-11T15:49:43Z

It is likely to be caused by NOP padding in the method bytecode, after the return instruction. It can be seen below with JEB, with the "Show instructions in gap" option enabled.

skylot · 2024-09-11T19:17:36Z

@draekko, @jpstotz thanks for sample and issue confirm

This issue caused by incorrect debug info offset in dex method code section.
(Check DEX format docs https://source.android.com/docs/core/runtime/dex-format#code-item for debug_info_off field.)
Looks like it was corrupted intentionally to disrupt decompilation or disassemble.
Anyway, such incorrect data clearly reported by ApkTool/Smali like this:

Lcom/onecoder/coosporide/main/ChartFragment;->createCircleGradientDrawable(II)Landroid/graphics/drawable/Drawable;: Invalid debug offset

So I also commit a similar check and now instead of error with stacktrace, simple warning is added:

    /* JADX WARN: Invalid debug info offset */
    public final Drawable createCircleGradientDrawable(int startColor, int endColor) {
        return null;
    }

Funny that here argument names comes from Kotlin metadata, which are not removed 🤣

draekko · 2024-09-12T10:06:48Z

Just tried apktool and all the smali code is nop'ed out as jackpwa mentioned, any suggestions on how i might go about to retrieve the code? Thanks in advance

skylot · 2024-09-12T17:02:15Z

any suggestions on how i might go about to retrieve the code?

@draekko looks like this is not possible using only static analysis tools like jadx, so you also need a dynamic/runtime tool like frida to catch dex files restored/decrypted at runtime. ApkId report that this apk uses Ijiami packer, so you can try to search guides to fight it.

draekko · 2024-09-13T16:56:10Z

Thanks for the suggestion, will look into them.
