I have installed Android Studio 1.2.1.1 on Linux Mint 17.1 32 bits, have setup the "Hello world" application. Connected my mobile Lava Xolo Q800 X. When I try to run the application, in Choose Device dialog box the running device list shows like ????????? null] for device name.

In Android developer website it is said to create /etc/udev/rules.d/51-android.rules file with the related vendor Id. There is no vendor Id for Lava in the web page and also I'm not able to find from Google.

How can I fix this error?

Use the lsusb command in a terminal, you will find the corresponding idVendor for you device (in bold here):

Bus 002 Device 026: ID 04e8:6860 Samsung Electronics Co. […]

Then add a rule to your /etc/udev/rules.d/51-android.rules like this (replace 04e8 with your idVendor):

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"

Have you installed the device driver for your phone? This is nessesary to do for most of the Android devices, before you can find them in Android Studio. You find the device drivers on the vendors website. The only exceptions to this is the clean Android devices.

Install the drivers. If you cant find the cd in the box download the driver from the site.
