ADB Android Device Unauthorized

Question

Since I reinstalled Eclipse (simply deleted and downloaded it again) I can't debug my applications on Samsung Galaxy i9001 (with CyanogenMod - Android 4.4.2). It worked fine before reinstallation.

Unplug/plug, Uncheck/check "Debug Enabled", adb kill-server/adb start-server, restart phone/computer doesn't work for me. On the device authorize dialog never appears (but I remember that dialog appeared before reinstallation). I have no idea how to force this authorize dialog to display. There is no abd_key.pub file in .android directory. When i try read cpu info DDMS says:

[2014-04-15 12:47:06 - DDMS] device unauthorized. Please check the confirmation dialog on your device.

Any ideas? Is it possible to generate keys manually without confirmation dialog?

USB Connection

Wireless Connection

Answer 1

Steps that worked for me:
1. Disconnect phone from usb cable
2. Revoke USB Debugging on phone
3. Restart the device
4. Reconnect the device
The most important part was rebooting the device. Didn't work without it .

Answer 2

I was getting this error with my Nexus 10. I tried all of the answers I could find, and then I realized I was using a different USB port than usual. I switched to using the port I usually use, which is on the other side of my laptop, and the authorization popped up on my tablet!

Answer 3

This is error because your window version haven't driver for usb 3.0 to receiver authenticate permission from phone. I spent 5 day with this bug. Now, install 58964_Intel(R)_USB_3.0 driver. And continue with awesome code!

i use this link to download driver

Answer 5

adb usb worked for me This restarts the adb daemon listening on the USB port The command returned:

error: device unauthorized. Please check the confirmation dialog on your device

. But the prompt for the RSA key showed up on the phone straight away. Once I approved, everything started working as expected

Answer 6

I had the same problem. It was resolved by setting "USB computer connection" to "Camera (PTP)" instead of "Media Device (MTP)
