Android Studio can’t open Android Device Monitor


Recently I had this issue: my Android Device Monitor didn’t open and and an error log file was generated every time I was tring to open it, under Android – sdk – toolslibmonitor-x86_64configuration. Also, I have to mention that it happened on Windows.

I googled it and found different answers but none worked for me, and after some further digging, I found the solution for my case.

Solution (that worked for me)

My .android folder was read-only so I had to change this. The file is located in my case under C:\Users\<your_user>. So right-click on the folderselect Propertiesuncheck read-only option.
