My real device is Sony Xperia c6502 with android version 4.3 I'm sure I connect it to my computer and I turn Developer options/ USB debugging on
In SDK manager, Google USB driver is already installed.
I downloaded Xperia Z Driver from this page:http://developer.sonymobile.com/downloads/drivers/ But I don't know how to use it
No PTP mode option in USB Connectivity in my phone
My device is not shown in Android Device Monitor and thus I can't run app test on my phone.
How to let my Android Studio catch my phone?
Some possible solutions:
On your notification bar, expand it and click the connection. Then select connect as Camera (PTP)
(not as media device)
Try with another USB cable.
Go to your SDK manager and install (I see you updated your answer regarding this)Google USB Driver
Follow the instructions on OEM USD Drivers
