IntelliJ Community did not detect Android Emulator

1. Launch Android emulator separately from terminal. 

2. `flutter doctor` runs fine, detected that device. `flutter run` can also run my program. 

3. Launch IntelliJ CE from the favorite icon created by installation script. Can't find the emulator. 

4. Instead, launch IntelliJ CE from another separate termial with `idea.sh`, it finds the emulator and works fine. 

I guess when launching from terminal, the ANDROID_HOME is correctly set, while from the favorite icon, the ANDROID_HOME is NOT set after all. 

Please let me know if I am the only one having this issue, or this is common.
