Hi, I am trying to update a project from the old format for mpp projects to the current format, but I stuck with a problem when running the android app... it seems that the Activity is not found in the main dex...

I did check if the Activity in the AndroidManifest is right and I could run the same :app code switching the local mpp project to a published dep. I also can ran the unit tests from commonTest just fine.
Does anyone has ran into something like that? I uploaded my current work here https://github.com/BugsBunnyBR/forms-mpp-problem if anyone want to take a look...

I've never had a similar issue, and I've been doing some Android-specific MPP stuff. I imaging you've already tried cleaning and rebuilding?

[juliocbcotta]

Yes, I did. I even upgraded my AGP to use the 3.4.0 beta..

The project has no secret, but I fail to understand why it compiles and fails at runtime.

[josephivie]

Idea: try compiling it to an AAR using com.android.library instead. Then, open said AAR and see if you can find your .class file. That might give a start into figuring out what's up.

After hours looking at other projects I found the culprit.
I was missing

kotlin {
    targets.fromPreset(presets.android, 'android')
}

in the :app module
