The window shows the option only of them emulator but not of Nexus4 I have nexus 4 drivers installed too. What can be the problem?

Answer 2

Did you try to restart the Eclipse? because I had pretty much same issue with my galaxy s2.

Answer 3

It is in fact an issue I have faced for long.

Use the SDK on Linux. It works then. For me it doesn't work when on Windows....

Answer 4

try:

$ adb devices

and it should output something different than:

????????????

if not then you don't have permissions to access your device, you need to restart the adb daemon, in Linux you would use:

$ adb kill-server

and then run the daemon as root:

$ sudo adb start-server

after that you would be able to use it; I'm not sure how to do this on Windows but I hope it helps

尝试使用nexus 4工具包重新安装驱动程序（您可以在xda上找到它）
