android device is not visible for run eclipse

Question

I try to test my application with real device (samsung galaxi 2) in eclipse, however device is not visible. The settings in the device is not a problem because I can run tests on another comp. In eclipse google usb driver is installed. What else can be a problem?

Answer 1

验证是否正确安装了驱动程序（用于调试的驱动程序），并将USB计算机连接设置为对应的类型（媒体设备（MTP），相机（PTP），大容量存储（UMS））

Answer 2

确保清单中的最低SDK低于设备的API：

<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="19"/>

Answer 3

Check all this thinks :

1. -The USB driver is installed : USB Driver
2. -The device is in debug mode :
3. -The USB computer connection (try each mode, and reinstall the driver for each mode):
4. -Your cable is not damaged ^^

Note : there are too driver to install, one without USB debugging enabled, and one with USB debugging enabled
