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!
