Problem

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 – tools – lib – monitor-x86_64 – configuration. 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 folder – select Properties – uncheck read-only option.

Other Solutions

Below there are different other solutions in case the above one doesn’t work for you.

• Close Android Studio and run it again as Administrator;
• Kill or end “monitior.exe” running process using Taskmanager in Windows
• Try to update Android SDK Tools
• Make sure you have JAVA_HOME in your system environment variables

  JAVA_HOME=C:/Program Files/Java/jdk1.8.0_11
