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  lt path-to-your-adt-sdk-package gt  sdk platform-tools adb cp  usr bin fastboot  lt path-to-your-adt-sdk-package gt  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

On the phone   Have you enabled Developer Mode  Have you enabled USB debugging within the Developer Tools menu in settings  this menu doesn t appear unless you ve enabled Developer Mode  Do you have a good and securely connected USB cable    In Android Studio   In Edit Run Debug Configurations  do you have  Target  USB Device   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

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    I hope this helps someone

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

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
