Android Studio Gradle Already disposed Module

Note: this is purely an IDEA/AS issue, gradlew clean | Build > Clean | Build > Rebuild will just waste your time.

Most of the solutions here are blind stabbings in the dark. Here's what I found to be the root cause:

1. Some of the .iml files may be missing (maybe because we deleted it), check if the module erroring has .iml.
2. If it is missing, check if .idea/modules.xml has an entry for that module

While syncing I noticed that IDEA/AS tries to put a new duplicate entry into .idea/modules.xml while there's already one. This duplicate entry is probably disposed of twice while the sync tries to reset the modules in memory.

Quick Solution: In order to make it work the easiest is to delete .idea/modules.xml along with the .iml files. Additionally may worth deleting .idea/modules/ folder if it exists. Restart Android Studio (no need to clear cache) and force a Gradle sync from Gradle view or toolbar to recreate the files.

I figured out this problem by:

1. ./gradlew clean
2. Restart Android Studio

Simplest solution. (Try this first).

1. Quit and Restart Android studio. (Quit not close)

2. Build > Clean your project if needed.

works for me: File -> Invalidate Caches / Restart... -> Invalidate and Restart
