I would like to know whether is it possible to use my HTC wildfire (some links would be nice) for android development instead of the emulator.
I have tried to find the information by Google, but so far no useful results.
If I get more information, I’ll update here.

[When I used wildfire with eclipse, I got this.]
Thank you very much.
From your screenshot, it looks like you do not have the permissions set properly to access the USB device.
Either try to run the adb service as root:
OR, the more permanent solution is to set up udev rules for USB device permissions. See the instructions in step 3 of the android Developing on a Device page.
Log in as root and create this file: /etc/udev/rules.d/51-android.rules. The udev system checks this file for special cases when devices are detected.
Edit the file to read:
SUBSYSTEM==”usb”, SYSFS{idVendor}==”0bb4″, MODE=”0666″
This sets permission bits on the dev node to world read and writeable for the special case where the USB vendor ID is equal to 0bb4.
Now execute:
chmod a+r /etc/udev/rules.d/51-android.rules
… gives world read permission to these android rules which is needed to let the udev daemon process this new rule.
