mobile-install does not work with custom AppComponentFactory

[vgrec]

Description of the bug:

In our project we are using a custom AppComponentFactory for a particular use case. When we use bazel build to build the app, the custom AppComponentFactory is properly taken into account. However, when we build using bazel mobile-install, a ClassNotFoundException is thrown at application startup.

The ClassNotFoundException tells that the custom AppComponentFactory could not be found. What is worth mentioning though, is that we decompiled the apk and verified that the custom AppComponentFactory is present.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Checkout this POC project: https://github.com/vgrec/bazel-appcomponentfactory-issue
2. Build the project with bazel mobile-install //src/main:app
3. Open the app
4. Check the error logs

Logs:

java.lang.ClassNotFoundException: Didn't find class "com.example.bazel.MainAppComponentFactory" on path ...

Which operating system are you running Bazel on?

macOS Ventura 13.2

What is the output of bazel info release?

release 6.0.0

What's the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?

We're hitting the same issue with Bazel 6.2.0

@ahumesky : I know the focus is currently on mobile-install V3, but is there a known workaround for this?
