Android Device Not Showing Up In Ddms

Running Android 2.2 on a Galaxy S. Host is an OS X 10.6.4 machine. DDMS in Eclipse reports no devices being connected. adb devices -- nothing. I've tried: Rebooting the phone Tog

Solution 1:

On recent macbook pros, one port will not work consistently. Tested on 2 different Macbook Pros.

Solution 2:

Had the same issues with colleagues and found that somehow, "USB Debugging" was disabled in the settings, even though it had worked fine just a few days before.

Just thought I'd mention it because it had us stumped for a bit.

Solution 3:

My development device (LG GT540 running Android 2.1, OS X 10.6.8) also mysteriously stopped appearing in "adb devices" today. The only change from yesterday that I recall was logging out of my Mac account (as I typically do at the end of the day) and unplugging the USB cable (which I rarely do not).

I tried the above suggestions, but the device didn't reappear until after:

1. Restarting the Mac,
2. Performing a factory data reset on the device (Settings > Privacy > Reset),
3. Restarting the device in Safe-Mode (hold Home + Hangup buttons while powering on),
4. Re-toggling the developer-y settings:
   1. Enabling USB debugging for development.
   2. Disabling SD card mass storage only.
5. And, finally, restarting the device normally.

Who knows what the problem really was, but I can see and deploy to my device again.

Solution 4:

Had to dig for this sucker:

Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.
