Android Studio does not show my device when running the project


When i tried to run my project in android studio it does not show any device

But i had correctly installed the adb interface driver and it also show in my device manager(Android Device -> Android Composite ADB Interface ).

My device is LAVA iris X1 (kitkat 4.4.2)

  1. Usb debugging was on

  2. usb connection was switched to PTP (Camera)

I had also tried certain posts but non of them works

Please provide a helpful solution.

Thanks in advance.

launch 2 devices at the same time, sometimes the firts device launched is not showing probably for some bug but the second is recognized
