Visual Studio and Android Device Monitor doesn't detect any devices

Question

I\'ve just installed VS2015 Community with Xamarin to develop some mobile apps. The problem is, I can\'t achieve debugging Android apps on any device. Android Device Monitor

Answer 1

Sometimes just restarting Visual Studio might help

Answer 2

My understanding is that the Google USB Drivers from the Android SDK Manager only work for Google Nexus devices (at least according to https://developer.android.com/studio/run/win-usb.html); annoyingly enough, to use other kinds of devices you'll probably need to download vendor-specific drivers. For example, I definitely had to download Motorola's drivers to use my Droid for debugging purposes. Unfortunately, for whatever reason Windows wasn't able to automatically detect that that's what it needed to download, so I had to download them manually.

Answer 3

You most likely did not grant access to the device. Try to go into the developer settings on the smartphone and revoke the USB debugging authorisation. Then connect the phone to the pc and and wait for a popup on the phone which you should accept. After accepting you should see your device with adb devices.

You can also try to set the connection mode to MTP (instead of the camera PTP).

Hope it helps!

Answer 4

This just happened to me. And it seems setting the startup project to your Android project fixed it.

Answer 5

Enable the device for development

Goto: Device > Settings > Developer Options > tick USB debugging

Answer 6

I had the same issue after updating Visual Studio found that in recent versions is better if you open VS in administrator mode to properly work, this should fix the problem.
