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 /sdk/platform-tools/adb
cp /usr/bin/fastboot /sdk/platformtools/fastboot

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