For me the issue was the running adb service/server was frozen (it tend to do that every now and often). The solution was to go to "Activity Monitor" (I'm on a Mac) => Find the "adb" process and force quit it. Then, running the app from Android Studio worked again.

Alternative terminal solution: The "adb" process can also be found and killed from terminal. List processes:

ps -ax

Find the adb process id, e.g.

17582 ??         0:01.26 adb -L tcp:5037 fork-server server --reply-fd 4

Kill it:

kill 17582

On the phone, after enabling "Developer Mode", the following settings will appear: Developer Options -> Default USB Configuration. It will let you choose how to use USB device e. g.:

  • File transfer
  • USB tethering
  • MIDI
  • PTP etc.

Try all of them. I got a chance of debugging working with one option and not working with another.

I had this problem after upgrading from Android Studio 2.3 to 3.0. As simple as it sounds, I actually just restarted my phone to fix it.

My guess is that the adb server on the phone somehow cached something from the previous installation of android studio, maybe a connection object or something, and by restarting the adb server it resolved the issue.

This happened to me on android studio version 4 after doing an update to the IDE. The "invalidate caches and restart" option fixed it.

I already had this problem before.

Choose "Run" then "Edit Configurations". In the "General" tab, check the "Deployment Target Options" section.

In my case, the target was already set to "USB Device" and the checkbox "Use same device for future launches" was checked.

I had to change the target to "Show Device Chooser Dialog" and I unchecked the check box. Then my device appeared in the list.

If your device still doesn't appear, then you have to enable USB-Debugging in the smartphone settings again.

  1. If suppose the android device is not getting connected by android studio then download "PDANet+"(for all android devices).

  2. Or also you can do these following steps:

    • Go to Run tab on toolbar of android studio.
    • Then click on edit configuration
    • In General tab there will "Deployment Target Option" click on "Target" and choose "Open select deployment target dialog" and uncheck the checkbox from below.
    • And at last click OK. Finish.

On the phone

  1. Have you enabled Developer Mode?

  2. Have you enabled USB debugging within the Developer Tools menu in settings (this menu doesn't appear unless you've enabled Developer Mode)

  3. Do you have a good and securely connected USB cable?

In Android Studio

  1. In Edit Run/Debug Configurations, do you have "Target: USB Device"?

  2. It may help to download the latest version of the USB driver for that particular phone.

It's also helpful to know whether your phone appears as a recognised device at the operating system level. And when in doubt, reboot everything you can think of.

Optional

  1. How to enable Developer options and USB debugging
    • Open Settings menu on Home screen.

I have used a different USB cable and it started working. This is weird because the USB cable (which was not detected in android studio) was charging the phone. This made me feel like there was a problem on my Mac.

However changing the cable worked for me. Just check this option as well if you got stuck with this problem.

I had the same thing on Windows 7 where I had the device properly set and the driver installed, and I was routinely running on the device. Then suddenly I started getting this error every time. I opened the Edit Configurations dialog as described above, switched to an emulator, tried one run, then went to the same dialog and changed back to USB. Then if worked again.

If you are using 32-bit ubuntu (my case) then it is most likely that Android Studio has downloaded 64-bit version of adb and fastboot inside your sdk/platform-tools folder. I think you already have installed adb (and fastboot). If you haven't then run these commands in terminal:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb android-tools-fastboot

This will install 32-bit version of adb and fastboot. Now just replace the 64-bit adb and fastboot executable files in sdk/platform-tools with the installed 32-bit versions:

cp /usr/bin/adb <path-to-your-adt-sdk-package>/sdk/platform-tools/adb
cp /usr/bin/fastboot <path-to-your-adt-sdk-package>/sdk/platformtools/fastboot

Now your android studio should be able to run your App in your device.

Note: I had problem on Windows 7 but it might help you as well..

I had problem with android studio detecting my phone(Acer Liquid Zest 4G), tried restarting android studio, switching back and forth between PTP and MTP, OS was able to detect device normally.

So what I did was, in Developer Options i enabled USB debugging, USB connection is in PTP mode, then from phone manufacturer's site (you can find site for your phone here: https://developer.android.com/studio/run/oem-usb.html), I downloaded USB driver for my phone model, installed driver and android studio was able to detect my phone(there was no need for restart).

I will repeat again, you must have USB Debugging enabled in Developer Options, otherwise it won't work. Hope it helps.

trick that works for me when target device not found:

  • click the "attach debugger to android process" button. (that will enable adb integration for you)

  • click the run button
