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)
Yes, similar behavior on the Droid 2 Global. Seems as though you can get the USB recognized if you reboot out of recovery. But, otherwise once you are at console, adb devices shows the device as offline. Not sure how to remedy this problem.
But, as long as you aren't hacking the phone, the I tried it with normal power supply with the battery dropped, and it powered up. So it is getting power. I am not sure if its CyanogenTeam that just forgot to put some sort of indicator.. or what but, don't worry. Your battery is charging.
However, pushing .apks and other stuff is not easy anymore. But hey, when rooting a phone for a friend do you necessarily want them pushing anything.. Anywhere?
Faced same problem in Windows with Nexus 7 device.
Simply killing adb.exe process from Task Manager solved my problem.
I can't say for sure but after hours of random disconnections from my device (especially when trying to debug anything), I switched to a USB port that is NOT USB3.0 and that seem to solve the issue.
I had the same issue and i solved it by resetting the adb on eclipse.
on eclipse Go to:
DDMS(top right corner) -> Devices -> reset adb
I have a Windows 7 desktop with a Google Nexus 7 connected to that. I also had the 'offline' problem. Mine is resolved by revoking any previous authorization on Nexus. So now I get the prompt to authorize on Nexus--I am not saving the authorization for now at least--and I allow the authorization--and voila!--Android SDK correctly shows the device as 'asus-nexus_7-xxxx'. HTH
Mine was offline.
I unpluged and pluged again but with the mobile awake, a window opened asking permission.
So try to plug and unplug but with the phone awake.
