[Android][Qt Creator] plain hello world cpp, and bumblebee and avd emulator

[Faizol]

Hi all,

Development Platform: Fedora 20

I have two questions;

1. I tried to run a simple plain "Hello world" cpp file (New Project -> plain c++ projet) and set Desktop and Android as targets. Trying to deploy the program to the android emulator resulted in errors as the following
   @ Install to device: emulator-5554
   No platform plugin, neither libqtforandroid.so or libqtforandroidGL.so, included in package. Please include one.
   23:11:57: The process "/home/dev/Qt5.3.0/5.3/android_armv7/bin/androiddeployqt" exited with code 12.
   Error while building/deploying project helloworld (kit: Android for armeabi-v7a (GCC 4.8, Qt 5.3.0))
   When executing step 'Deploy to Android device'
   @

How to solve that?

Second question;
How to tell Qt Creator to start an android emulator through optirun or primusrun?

Thank you.
