Not able to connect adb after upgrate Android Studio to 3.4
unable to connect to adb.check the event log for a possible issue, verify that localhost entry is pointing to 127.0.0.1 or:: 1 for ipv4 or ipv6 Tried adb kill-server, restart, invalidate restart nothing works. Same issue reported over here https://issuetracker.google.com/issues/130791561 Note: I have not added any file or anything in studio, it's fresh installed Studio after format a full system still issue is there. Replace your platform-tools with this one and delete the other one. https://dl.google.com/android/repository/platform-tools_r26.0.0-windows.zip Basant I was also facing this issue
