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

For me, I tried the above. Turns out my USB cable was bad. I changed the cable and then it worked.

Answer 2

I had a big problem with my Samsung S10 Plus as it was not detecded by Android Studio on my Macbook even if I did all what is required to be detected, that is to say:

1. Enable developer mode (7 taps on Build version in Android settings)
2. Enable USB debugging

What I did is to start "Android File Transfer" on my Macbook and the magic happened. A popup appeared on my device asking if I want to authorize an USB access to it. I clicked "Yes, always" and now Android Studio can detect my device on my Mac :)

Answer 3

Change the connection method Build-In CD ROM it works for me

Answer 4

In my case it was due to already running and hanged adb.exe on another user under my PC. I had two users on my PC, the second user had the adb.exe process hanged even when I tried to end the process. It worked with me after (End Process Tree) from the Task Manager.

Hope this will help someone with multiple users :)

Answer 5

Try swapping the USB port the cable is plugged into.

Sounds crazy but after 20 minutes of debugging this worked for me.

Answer 6

On HTC mini one 2, besides enabling the Developer Options, the following worked for me:

1. Go to More in Wireless & Networks
2. Mobile Network Sharing
3. In USB network setting
4. Select Internet pass-through
