问题
So here I go again with yet another Android Studio tools error. I don't think this one has been reported before, I can't find any posts on it.
I am trying to open the Device Monitor (DDMS) in Android Studio by clicking on the following button:
Every time I get the same error. What's really puzzling is that its an Eclipse error, as shown in the image:
So it tells me to open a log file in the Android Studio SDK folder. The log file contains lots of text, but the main error is reported as:
!ENTRY org.eclipse.osgi 4 0 2015-05-27 09:40:53.091
!MESSAGE Application error
!STACK 1
java.io.IOException: The folder "C:\Users\JOHN%20SMITH\.android\monitor-workspace\.metadata" is read-only.

Why am I unable to open DDMS from Android Studio, and why is an Eclipse error thrown when trying to open DDMS from Android Studio ? Can anyone guide me ? Has anyone even seen this error before ? All responses will be gratefully appreciated.
EDIT:
As pointed out by Daniel Nugent in the comments below, the DDMS shipped with Studio seems to be exactly, exactly the same as the one in Eclipse. Wonder if this is a clue to the problem. And for the record, I do have Eclipse installed on my PC for maintaining some legacy code.
EDIT 2:
The solution is here. Many, many thanks to Skizo and Blackbelt for this, both of you were spot-on!

I think the problem is about your %20 in your name, then you can try it out this answer, it seems like yours :
I've just come across this problem too. My workaround was to create a symbolic >directory link from "Test%20User" to "Test User".
- Open a command prompt as administrator. (shift+ctrl+(enter or click) on the >icon will do this)
- cd C:\Users
- mklink /d "Test%20User" "Test User"
- Launch monitor.bat and it should work.

you must run the application (android Studio) with a administrator permission
