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

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
