Editor to share with you what to do if you can't find a device for ADB debugging Android under Ubuntu. I believe most people don't know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

Recently, I was writing a test program to play rtsp, which needs to be tested on a real machine. As a result, on Ubuntu 11.04. after connecting to the phone of Android 2.1, adb service did not find the device, only the simulator. So I looked up the information on the Internet, and finally solved this problem after research.

First of all, confirm that I have ticked the settings-applications-development-debug mode of G1. And the phone also has a hint of connected, but adb doesn't recognize it. * A solution has been found to take shape at once.

First, follow the instructions on SDK to create the rules file for udev, and then:

When connecting an Android device through usb under Ubuntu 11.04, when using adb, the device cannot be found. The solution is as follows:

1. Run lsusb on the terminal

You will find that the result will have a similar record as follows:

Bus 001 Device 008: ID 0bb4:0c02 High Tech Computer Corp.

Type at this time

Sudo vim / etc/udev/rules.d/50-Android.rules

Add the following text to the open file:

SUBSYSTEM== "usb", SYSFS {"High Tech Computer Corp."} = "0bb4", MODE= "0666"

two。 Run the following command:

Sudo chmod a+rx / etc/udev/rules.d/50-Android.rules sudo / etc/init.d/udev restart

3. Run under Android sdk's tools directory (this step is important, it must be sudo, otherwise it won't work)

Sudo. / adb kill-server sudo. / adb devices

Then, you can operate directly with adb.

If you continue to execute the adb devices command under Ubuntu 11.04, the result returned is:

List of devices attached? No permissions

This means that the device connected to the USB is recognizable. After searching the Internet, I learned that adb server needs to be started with the authority of root, so I have the following command:

Www.linuxidc.com@linuxidc-laptop:~/Dev/Java/Android/android-sdk-linux_86/tools$. / adb kill-server www.linuxidc.com@linuxidc-laptop:~/Dev/Java/Android/android-sdk-linux_86/tools$ sudo. / adb start-server * daemon not running. Starting it now * * daemon started successfully *

The * command is used to kill the currently running server, and the second command starts the new server with the authority of root. We can look at devices again:

Www.linuxidc.com@linuxidc-laptop:~/Dev/Java/Android/android-sdk-linux_86/tools$. / adb devices List of devices attached HT848KV04386 device

This time the equipment was correctly identified. Naturally, tools like ddms can come in handy.
