SDK Location not found. Define location with an ANDROID_SDK_ROOT environment variable. (expo modules error)
If you're on windows, you'll need to edit your system (system wide)/user (just you) environment variables. You'll want to add an environment variable named ANDROID_SDK_ROOT (legacy env variable name) and ANDROID_HOME that points to your android studio's sdk location. It'll most likely look something like this:
C:\Users\Username\AppData\Local\Android\Sdk (copy paste this into the box)
Delete your node_modules folder, invalidate caches and restart in android studio and restart your machine. Follow the steps again in the setup section.
'.' is not recognized as an internal or external command, operable program or batch file. (npm run buildRelease error)
Run this line in the terminal instead: cd android ; ./gradlew clean ; ./gradlew assembleRelease
