Android Studio doesn't recognize my device

Question

Here is the problem. I want to run my Android Studio apps on my device (Samsung Galaxy Ace 2). But nothing works for me. Tell me what I\'ve missed:

1) USB debugging

Answer 1

LG Optimus Zone 2 pp415 d\n connect in mtp, but does work in internet connection mode. Lost lots of time messing with it. There's no doc for this, but I'd suggest trying all 4 of the connection options. Only 1 that works for me is Internet Connection->Ethernet, then win 8 auto-detects a driver and installs it. In MTP mode despite all drivers being registered with device manager, adb doesn't pick it up.

Answer 2

I had the same problem. So here is what i did

1. reinstalled the device driver
2. changed the USB computer connection from MTP to Mass storage(UMS)

And it worked.

Answer 3

I also tried above solutions but got no luck. So here's what I did:

1. Download and install PdaNet+ to fix connection issues between my computer and android device
2. Enable USB debugging on my android device
3. Unplug the phone and plug it again after it's installed
4. Run my app and voila! My android device is now recognized by Android Studio
