Android Studio logcat BUG spamming java.io.IOException: Connection refused

Question

In Android Studio when phone is connected for debugging logcat keeps spamming this error:

06-27 00:17:17.440     947-2476/? E/UsbDebuggingManager﹕ Communication error:
java.io.IOException: Connection refused
        at android.net.LocalSocketImpl.connectLocal(Native Method)
        at android.net.LocalSocketImpl.connect(LocalSocketImpl.java:290)
        at android.net.LocalSocket.connect(LocalSocket.java:130)
        at com.android.server.usb.UsbDebuggingManager.listenToSocket(UsbDebuggingManager.java:75)
        at com.android.server.usb.UsbDebuggingManager.run(UsbDebuggingManager.java:111)
        at java.lang.Thread.run(Thread.java:841)

It's really anoying and it makes very difficult to debug.

Answer 1

You can filter this out of logcat using the Filter Configuration dropdown box to the right-hand side of the search box.

Then enter a Log Tag regex:

For my Nexus 5, I'm using this tag regex to suppress the spammy logs: ^(?!WifiStateMachine|ConnectivityService|ConnectivityManager)
