I have a Sony Xperia C2305 with Android version 4.2.2. Problem is I cannot deploy, debug and test android app within it. Neither Eclipse ADT nor Android Studio detect this phone. I found this phone detects on Windows 7 but I am using Windows 8.1.
How can I solve this detection problem? I also visited the Sony sites for driver, but I could not find any driver for this phone. Besides that I think all other relevant settings are OK.
I think I know how to fix your problem. Open "my computer" -> device manager -> other devices -> Android -> right click and choose update driver. Browse my computer for Driver Software -> Let me pick from a list of device drivers on my computer. Then scroll down and find Sony so0101 driver.
If you haven't this driver in list, you should install it from http://forum.xda-developers.com/showpost.php?p=50386981&postcount=5 this attachment. Just unzip and run DPInst64 (don't forget to set compatibility with windows vista sp2). After that you can choose sony so0101 driver.
It works for my Sony Xperia M2 on windows 8.1
