Answer 1

Other post had gave a solution for the problem, according to post 1 and post 2 , your problem is caused by %20 in your name:

The folder "C:\Users\Mehran%20khan.android\monitor-workspace.metadata" is read-only. at 

You can follow the steps:

1. Open a command prompt as administrator. (shift+ctrl+(enter or click) on the icon will do this)

2. cd C:\\Users
mklink /d "Mehran%20khan.android" "Mehran khan.android"

3. Launch Android Studio and Sync the project

I have not tried the solution because I have not come across the problem, if it works, please let me know~
