Eclipse doesn't find my device

Question

I've updated everything. No problem with driver. Added android:debuggable="true" to the . USB debugging mode on. But still dont work. My OS is Win7, my device is Huawei.

Answer 1

• Make sure, that your usb connection type is " Charge only ",
• disable and the enable the USB debugging on your device ( Menu->Settings->Applications->Development->USB debugging uncheck -> check ),

and Eclipse should recognize it.

Update
I also have to close the emulator window (if I have running any), and this works for me all the time.

Answer 2

Check the USB-to-microUSB cable. I was using one that I suspect only charges battery power, but no data transmission. After changing to another cable, my phone successfully appeared under android device in the eclipse run window.

Answer 3

Right click on your project, select 'Run As Configuration'. then Select 'Android Application' ->you application and from 'target tab' uncheck all emulators. After this, make sure all emulators are down and then right click on your application and 'Run As' -> Android Application'. it will show you the option to select your device as target.

Answer 4

is your phone in development mode? settings --> applications --> USB debugging

Answer 5

Try to restart adb server , run

adb kill-server
adb start-server

from command prompt

Answer 6

Be sure that driver installed successfully, open device manager and find your device driver installed. install your device software (like Kies in case of Samsung mobiles) it will install drivers automatically

Answer 7

For other people having the same problem. I have the same problem before and tried all solution but the problem remain the same until I check the Device Manager and under Universal Serial Bus controllers, once I plug-in the device and I got an 'Unknown Device' in the list. So, my solution is remove the unknown driver, scan the hardware and reinstall the driver for my device and now is working. Hope it helps.

Answer 8

我猜你的驱动程序有问题试试从这里安装你的驱动程序

Answer 9

花时间在'Debug'下查找我的设备 - 在'Run'下找到设备。

Answer 10

Solution from a different angle: Type "adb devices" in terminal (the executable is in platform-tools directory of Android SDK). If the output shows that the device exists, this may be related to the project you are trying to run (if not then the device is not installed correctly, driver issue). If the device's Android version is lower than the project's minimum version (see AndroidManifest.xml file look for android:minSdkVersion), the device will not appear in the launch window. Try a lower number for android:minSdkVersion than the one specified which is smaller or uquals your device's version. Please take in account that this may cause the app to crash if your device does not support the API used in the project.

Answer 11

检查是否已为设备安装USB驱动程序。

Answer 12

I've meet this situation many times before , there's some workaround about this. :

• unplug the cable and then plug in again
• restart your device, or
• restart your computer

that way the device will online again.
