[Android-development] Debugging on device, any success?

[BogDan]

Hi Harri,

  I think your problem is QtCreator, QTC 3.2 has a bug which prevents any QWidget based apps to be debugged.

You have two options:
 - enable QML debugging, even your application doesn't use it.
 - compile QTC from sources.

Cheers,
BogDan.

I tried with both r9c and r10b.  (Logs were from r9c)

Btw.  Does anything else except the deployed gdbserver matter on device 
side?
