adb error: more than one device - android [duplicate]

Answer 1

You can run every command of adb by selecting the device by deviceID. run command to get Device Id:

adb devices

you will get the list of all available devices something like this:

 device
emulator-5554 offline

the copy the device id run commad like this:

adb -s  

example:

adb -s  tcpip 5555

OR

adb -s  forward tcp:59900 tcp:59900

this will not get the error like "more than one device/emulator"

Thanks
