Android device is not connected to USB for debugging (Android studio)

Question

I am trying to debug my application using a real device instead on the emulator. When I try to connect, it gives me the message:

USB device not found<

Answer 1

The solution for me was following the instructions at https://developer.android.com/studio/run/oem-usb.html#InstallingDriver. Specifically, the key part from that link that helped me to find the solution was this: "Install a USB Driver. First, find the appropriate driver for your device from the OEM drivers table below." This means that you cannot find a single link that applies to everyone as the solution. It will depend on your device! "So I visited the page to get OEM Drivers at https://developer.android.com/studio/run/oem-usb.html#Drivers. In my case, the device I was using was an LG K8 LTE. I had to go to http://www.lg.com/us/support/software-firmware-drivers#, Browse by product and I found the driver I needed under the Model Number "LGAS375 KG K8 ACG - AS375", Cell Phone Product. From http://www.lg.com/us/support-mobile/lg-LGAS375 I used the "Install the USB DRIVER" for Windows (http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425).

Depending on the device model you are using, you will need to find the specific drivers that work for your phone, and that should work.

Answer 2

I have a Samsung Galaxy S4. Although visible from Devices, my phone was not listed as connected from Android Studio. I tried a few things independently, and then together, and found that only a combination of steps fixed the issue, so this is for you if measures listed above or on another site did not work on their own.

1. Enable USB debugging from "Developer Options"
2. Download Kies from Samsung. I believe Samsung US has replaced Kies with a new software called Smart Switch, but this did not resolve anything for me. I found a Samsung UK download of Kies that worked fine.
3. After connecting your phone to your PC via USB, go to your phone notifications and click on USB settings at the top. Switch it to Camera mode.

I repeat, only all 3 of these together fixed the issue, so if some fixes you have tried haven't worked, use these 3 and it could fix the problem for you. Best of luck.

Answer 3

If you're using a USB Type-C cable, check if it has the charging and data transfer capability. Many USB Type-C cables are for charging only, and are not recognized by Android Studio.

Answer 4

Windows, many times it will not recognize the device fully and because of driver issues, the device won't show up.

• 1).go to settings

  2).control panel

  3).hardware and sound

  4).device manager

Answer 5

You need to install the driver first. Follow the instructions on the Android's developers website:

Answer 6

I had this problem with a Nexus 7 - it appeared in Device Manager fine but wasn't recognised by Android Studio. The device had USB debugging turned on. Eventually I noticed an icon in the top left hand corner that said "Connected as a media device. Touch for other USB options." When I selected this I was able to change from Media Device (MTP) to Camera (PTP) and then it started working.
