Fail to launch Android Emulator from Titanium Studio

When select run on Android Emulator, it fail to launch and showing error message below:

[ERROR] :  Emulator process exited with code 1

This can be fixed by setting correct path to android sdk platform tools in ~/.bash_profile

export PATH=/Users/etp_user/android-sdk-macosx/platform-tools:$PATH

And then in Titanium Studio Terminal, run .bash_profile manually.
