Eclipse and Android: cannot debug on Samsung Galaxy S2 because not detected

Question

I am just starting to learn on Android development. I use Ubuntu 11.10 and Eclipse. I have installed the needed plugins from android development, and I have also write yet some examples that compiles and run fine on the emulator.

But somethings as multitouch cannot be tested on the emulator, so I want to test them on my real Samsung Galaxy S2 device. The problem is that I have tried everything I have found on the web on this, but still have not been able to use it.

When I run ./adb devices, it does show none, although the device IS attached.

$ lsusb
...
Bus 001 Device 012: ID 04e8:6860 Samsung Electronics Co., Ltd 
$ ./adb devices
List of devices attached 

I have modified /etc/udev/rules.d/51-android.rules many times in different ways following instructions on the web, but none of them make a difference. Currently I have this line in it:

SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", ATTRS{idProduct}="6860", MODE="0666", GROUP="plugdev"

Of course I tried restarting udev and adb services, even rebooting the whole system, but it did not work neither.

Any hint?

Thanks a lot in advance,

Answer 1

Enable USB Debugging on the device from the Settings -> Applications -> Development

Answer 2

Try Samsung kies, it delivers suitable ADB driver: http://www.samsung.com/uk/support/usefulsoftware/KIES/JSP

With the right adb driver (from kies or elsewhere) it should work flawlessly

EDIT: on linux: http://developer.android.com/tools/device.html

If you're developing on Ubuntu Linux, you need to add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, see USB Vendor IDs, below. To set up device detection on Ubuntu Linux: Log in as root and create this file: /etc/udev/rules.d/51-android.rules. Use this format to add each vendor to the file: SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"

In this example, the vendor ID is for HTC. The MODE assignment specifies read/write permissions, and GROUP defines which Unix group owns the device node. Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules
