I typed which adb under the project folder, it showed usr/local/bin/adb.

I tried to add export PATH=/Users/myuser/Library/Android/sdk/platform-tools:$PATH and export PATH=/Users/myuser/Library/Android/sdk/tools:$PATH and then source ~/.bash_profile in my project folder.

I magically had some other adb in Expo folder, I replaced it with Android SDK adb to remove the last obstacle. I am using Android SDK adb on Android Studio, Expo and Genymotion now. I struggled several hours to make it work.
