Hi Kai,

Thanks for your reply. Then I have another question.. how can I assign the
argument to an Android application?

I have tried to use `adb shell` and launch the application by :

$ am start -n mypackage/org.qtproject.qt5.android.bindings.QtActivity -e
applicationArguments '-qmljsdebugger=port:61428'

But it is still not working. The result of  QApplication::arguments() don't
even contains the `-qmljsdebugger=port:61428` parameter.

(p.s I will file a bug for Qt Creator)
