Android device chooser - My device seems offline

I have developed an application and i was planning to deploy it to my HTC Desire. I have installed USB driver. I turned on USB debugging on the phone and choosed charge only when phone plugged-in. When I run application Android device chooser show my device offline. I am stuck at this point. Any help would be appreciated.

I develop at Eclipse Helios on Windows 7 (64bit)

Solution 1:

I've seen this happen a few times on my HTC Desire. I've never figured out whether the problem is in adb or the device but I usually do the following:

• Restart adb by issuing 'adb kill-server' followed by 'adb start-server' at a cmd prompt
• Disable and re-enable USB debugging on the phone
• Rebooting the phone if it still doesn't work.

99% of my issues have been resolved with these steps.

Solution 2:

I tried everything mutliple times in multiple orders, then stumbled across my particular answer:

Use a different USB cable - suddenly everything worked perfectly.

(Another potential answer for people that I found - make sure there is more than 15mb free space on the device.)

Solution 3:

Go to DDMS->Devices->Click on View Menu Down arrow on right side -> select "reset adb" option it will work

In Android Studio: open the Android Device Monitor (Tools->Android) and click on the arrow on the 'Devices' tab to reset the adb

Solution 4:

Faced same problem in Windows with Nexus 7 device.

Simply killing adb.exe process from Task Manager solved my problem.
