Koin: Error while app building with dexguard

[sankarsana]

Hi, i want to move a project from Toothpick to Koin. In the project is used the dexguard lib for protection.

At the building time, i getting en error.

This is the end of stactrace.

Unexpected error while computing stack sizes:
  Class       = [o/hD$if$10]
  Method      = [ˏ(Ljava/lang/Object;)Ljava/lang/Object;]
  Exception   = [java.lang.IllegalArgumentException] (Stack size becomes negative after instruction [18] astore v5 in [o/hD$if$10.ˏ(Ljava/lang/Object;)Ljava/lang/Object;])
:app:dexguardRelease FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:dexguardRelease'.
> Stack size becomes negative after instruction [18] astore v5 in [o/hD$if$10.ˏ(Ljava/lang/Object;)Ljava/lang/Object;]

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 3m 25s

ERROR: Job failed: exit code 1

Is it en error of a dexguard or a koin? How can i fix it?

P.S. This is error i have got after implementing the koin.

Hello Koin don't use any reflection/proxy, proguard should go without any problem.

Can you deactivate rules and activate it one by one?

[sankarsana]

I use dexguard not proguard. Or is it without a difference?

What rules do you mean?

[arnaudgiuliani]

I don't know dexguard sorry :/
Can you run without it?
Can you share a project on github?

You don't need any keep rules normally for Proguard or Dexguard. We use
Koin in a production app with Dexguard without any problem (0.9.x branch).

It runs excellent without it.

Can you share a project on github?

Unfortunately no. But there is nothing special.

[arnaudgiuliani]

What version do you use?

[arnaudgiuliani]

Fixed a regression about this topic. Fixed in 1.0.0-beta-5, you won't required any proguard rule for Koin or break any dex/shrink tool.

[sankarsana]

Thank you!
How can i try 1.0.0-beta-5 in my project?

[arnaudgiuliani]

depends on the used module,

    implementation "org.koin:koin-android-viewmodel:$koin_version"
// or  implementation "org.koin:koin-android:$koin_version"
//  or implementation "org.koin:koin-android-scope:$koin_version"

with koin_version as 1.0.0-beta-5

[sankarsana]

Аnd last question.
Can i use 1.0.0-beta-5 in production, or it's better to wait for the release?

[arnaudgiuliani]

You could. 1.0.0-beta-5 is already a good one. You can start to use it to make your first tests.

[sankarsana]

Thanks again!
I really liked the koin with its simplicity! I use one in another personal project.

[sankarsana]

I checked on 1.0.0-beta-5 version. The error is the same.

[arnaudgiuliani]

Can you make several tests: test it with proguard. Make it with dexguard in a 2nd time to check what is the problem, on which call there is a problem (also check your rules).

[sankarsana]

Ok i'll try to do it as soon as posible.
Thanks for you responsiveness!
