INSTALL_FAILED_UPDATE_INCOMPATIBLE when using same debug keystore as before

We are finally migrating from Eclipse ADT to Android Studio 2.3.2 (yes, I know).

We used a custom debug keystore in Eclipse Image of the custom debug keystore settings in Eclipse

I am attempting to use a debug keystore in Android Studio / gradle.

I followed the straightforward directions here: Android Developer: App Signing Image of app Signing properties in Android Studio Image of Build Type properties in Android Studio

All the Run configuration settings are defaults.

But when I try to run, I get the following failure: 

Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package --redacted-- signatures do not match the previously installed version; ignoring!

Yes, I could uninstall the app from my device and reinstall to get it working. But I don't want to. I thought the point of having and using a keystore is that you don't have to do that?

Why am I getting INSTALL_FAILED_UPDATE_INCOMPATIBLE even though I'm using the same debug keystore?

This answer led me to my own answer. I ran the signing report on my project and found that all my modules were using the "default" .android/app.keystore

I went into each of my modules and added the debug signing config. I was able to Run without any further problems.
