just unplug and then plug your USB cable. or else try with some other cable.
if it doesnot work then reboot your device.
Make sure you have enabled USB Debugging on Developer options of your phone.
This can be done by turning Settings -> Developer options > Usb debugging option on.

I am getting started with Android development. I have an older Samsung Galaxy S2. But Android Studio doesn't recognize the device. I've tried going to the USB utilities but I can't seem to find them. Is my device too old?
You will have to enable the "USB debugging" option in your phone:you will get this after enable the "developer mode" on your phone(aka "developer options" on some devices).
Check this guide to enable this mode.
In addition - if you want to test your apps on a real device you will need to have a data USB cable(if you can upload stuff from your phone to your computer than you have the correct type of cable )
In some devices after enabling developer mode and connecting a cable you should scroll from the top side of the screen (Like in the photo) and click on USB for file transfer, and select Transfer files.
In addition to enable the Developer mode, if yet doesn't work, take a look at this page https://developer.android.com/studio/run/oem-usb, maybe with this driver you will have your problem solved: http://www.samsung.com/us/support/downloads
You can also check at your adb to make sure your device is connected:
cd cd c:\Users\Linda\AppData\Local\Android\sdk\platform-tools\
run: adb devices
It must shows your device's ID.
Hope it helps.
I was not using the correct cable. I assumed since the phone was charging I was using the correct usb cable to connect to my pc. Found a different cable, I believe the same cable that came with the phone. Now my device is found and working.
I am using Windows 10 with Android Studio's latest version.
I have configured my LG device to be in developer mode (clicked 7 times on the build number and got message that I am in developer mode).
When I try to debug my app on the LG device, I get popup that tells me that there is "No connected device".
What could be the reason for that?
I can see the device on My Computer as a media device.
In addition to being a developer, you must also enable debugging. Try going into Developer Options and turning on USB Debugging.
You just enabled Developer Options. You need to enable USB Debugging.
Go to Your phone's Settings then go to Developer options and enable USB debugging there.
Also sometimes if you connect a new device to your pc it will install some built-in drivers for the device. So make sure you allow that process to be finished.
Still if the problem persists try another port of your computer.
P.S. For first time connection your phone will ask you to allow debugging permission from pc.
I am just beginner for android. And I just create'Hello World' app for initiate in Android Studio. But I am not able to run this on my mobile device. When I connecting this to device, it's connected but showing an error message "No USB device or running emulators detected".
I did everything what I can but no luck.
Sometimes it helps to switch the USB connection to one of the other modes available. (See your notification bar on the left when your phone is connected to your PC.)
You will need to enable developer options on your phone -
On Lollipop 5.1
Go to About Phone
Click 7 times on Build Number. Now Developer options are enabled
Go back and Click Developer options
Enable USB debugging under Debugging.
Android Studio 2.1.1: "no usb devices or running emulators detected"
Have you tried to kill and restart adb server through terminal. Also there might be a case that usb driver are not installed.
You just have to follow few steps:
Install PDA Net on your PC.

Make sure your USB cable is in properly working condition.
Make sure USB debugging is "ON" on your Android Device.
Now when you will connect your phone with PC, it will automatically install some drivers. Let it install. When PC is done with driver installation, it will show a pop-up on your phone. You have to allow your PC your access your phone through that pop-up on your phone.
Try it, I hope it will work!

The steps to enable usb debugging are
Go to Settings and tap on the build number a couple of times to enable developer options.
Open developer options and enable usb debugging.
Plug in your device to your computer and accept this authorization popup.
Click OK and and you should be good to go.
Continue reading if your device still don't turn up on the available debugging devices.
Once your device is connected to computer, you would have a notification saying, connected as media device/mass storage device.
Tap on it and change the connection type.
You should have that authorization popup now. Accept that and Voila. :)
Note: If you're on windows, you should install your device manufacturer's adb drivers. (If you can't find them, go for universal adb drivers.)

I'm relatively new to Android development, but I am having some issues with debugging on a new device I am working with.
Previously, I was using a Samsung Nexus S (Google development phone) running Android 4.0.4. When I plug in the USB, I get two notifications: USB connected, and USB debugging connected. When connected, Eclipse will prompt me to select the device I want to debug with, and I get tons of useful info in my LogCat window.
I recently started using a Samsung Galaxy S4, running Android 4.2.2. I have installed the USB driver from Samsung, but when I plug in the USB, I now only get a single notification: Connected as a media device. Now when I am running my app through Eclipse, it doesn't prompt me to select a device, and I get almost nothing in my LogCat window.
Can anyone instruct me on what I need to install or configure to get Eclipse to prompt me for the device, and give more detailed logging while debugging? USB debugging is enabled on the phone, in the Developer Options menu.
a) Have you turned on your Samsung S4 debugging mode
To activate the USB debugging:
From idle mode > tap on Menu > Settings > Applications > Development
Check "USB debugging"
b) Have you installed the necessary drivers for Debugging in Eclipse they are not the usual USB Drivers. Have a search on google you will find it
c) After installing reconnect you machine you will that it will mention on your device. Connected for debugging. And you LogCat will start populating
First, you need to set your phone into developer mode by clicking 7 times on Build version. Once this is done, you can check adb devices to see online devices connected to your machine. If you see your device, then you are good to go.
This link might help.
I had a similar issue with a tablet and a similar program. I found that if you forced the usb-sharing program to quit by using teh applications manager then eclipse would then find the phone. it is by no means a long term solution but at least you get to see the logcat.
