Android Device Monitor doesn't open - error on log file

If you are on windows try opening your Android Studio in Administrative Mode (Run as administrator)


I encounter this problem before. I fixed this issue by killing or ending "monitior.exe" running process using Taskmanager in Windows. Then click ADM (Android Device Monitor) and it works


I had the same issue with Mac OS X.

To solve it:

  • Open a terminal window
  • Navigate to your SDK
  • Locate the 'tools' folder
  • cd into it
  • run: sudo ./monitor
  • Type in your password

Good to go!
