Try installing Android Studio and see if you can deploy the application from there.

Thank you for your answer.
I installed Android Studio. The problem is that I can not use my mobiles phones remotely. I successfully builded apk and I copy them to the phone. The process is long (copying, installing).

I mean I can’t use “Unity remote” on my mobile phones. When I plug my mobiles into the computer, Unity detects them (Buid settings). But when I want to build and run the application on them, it’s written : “Android device 520005879… is not responding”. I try 4 mobiles (phone and tablet) and I face the same problem.
I updated my drivers, Android SDK,
I activated USB debugging.
Nb: in command line, when I typed : “abb devices”, it’s written “unauthorized”

I resolve the problem. In USB connection mode, on my phone, there are 4 options:

• Transfer files
• transfer images
• Connect a MIDI device
• Charge this phone.

I ONLY changed the connection mode to TRANSFER IMAGES. After that, I reveived a prompt asking me to viladate this connection mode. I did it and it works fine.

I know this is old thread. But just want to add how I solved this issue.

1. I close my Unity. At my phone, I click Revoke USB Debugging Authorisation and Ok to confirm.
2. Open Android Studio
3. Goto Tools | Connection Assistant. (Mine is V3.3.2)
4. Press Next, and there will be a page with “Restart ADB Server”.
5. Then on my phone there is dialog box asking to allow access from the PC.
6. Click Allow and that’s it. Give a try to run an app from Android Studio.
7. If OK, then close Android Studio and reopen Unity and it should able to build and run on phone now.

Thanks.
