Q:

Android: Debugging Android Applications on a Handset

I am trying debug android aplication on real phone (HTC Desire). 
I enabled USB debugging on my Android Device. 
Then i clicked on debug configuration,set Deployment Target Selection Mode to Manual and i clicked on debug but in Android Device Choiser i can't see my phone. 
What can i do please? 

A:

I assume you are using eclipse as your IDE.  I have to say that I use IDEA, So my experience with debugging could be different. 
These are the steps that I have to do:
1- Enable USB Debugging. (  You have already enabled it). 
2- Download HTC Sync software for my Computer (MacBook). 
3- Close already open emulator and connect the device to my computer. 
4- Start debugging session. 
I did not get a device chooser dialog also.  But to my surprise the phone was chosen over the emulator. I do not know how much you can get from my personal experience, but its worth a try.
