Android Studio无法打开（拒绝端口锁访问）

Question

When I open the Android Studio it gives the following error:

java.io.FileNotFoundException: C:\Users\HP\.AndroidStudio2.2\config\port.lock (Access is denied)

The javac path is correct and the file has anyone can access (port.lock)

This is the full error message which I was getting:

java.io.FileNotFoundException: C:\Users\HP\.AndroidStudio2.2\config\port.lock (Access is denied)

Answer 2

In my case, Java was installed under a different admin account on the default path, while I was trying to use Java under my admin account.
After a new installation of Java under my own admin account, the problem got solved.

Answer 3

Try to to delete everything under C:\\Users\\Administrator.gradle\\caches. There is a cache.properties.lock that is holding a global lock which is preventing you from running your script. Using MacOS you will find it in your home directory ~/.gradle/caches

It Works for me. I hope It Should fix the problem.

Answer 4

I had the same problem and in my case the problem was with permissions for the config folder - for some reason the config folder was read only. I changed the permissions and it was ok.

Answer 5

My Android Studio was not opening and throwing the same error as above.

I went and deleted the below folder -

.AndroidStudio3.5 (It should be in C:/users/[insert current user]/.androidstudio3.5 )

Delete the whole folder and try running the studio again.
