How to fix Android Studio which doesn’t start

Have you installed Android Studio and it doesn’t start after clicking the program icon? The fix is simple. Firstly, you should download (update to) the latest Java Development Kit (current version is 7u21).

One of my Java friends told me not to install Java (and anything Java related) to the default installation path because of spaces in the path (there’s a space in the Program Files) and have a special directory for Java like C:/Java/… Spaces in the path might cause errors.

I am punk so I am using the default paths anyway

Setting system variable – PATH

Notice: I will be working with Java path C:\Program Files\Java\jdk1.7.0_21\, it could be something else in your case, just check the path and if you have installed Java somewhere else, change it to desired destination.

Type SET PATH in commnad prompt, you should have something like C:\Program Files\Java\jdk1.7.0_21\bin in there. If not, open Control Panel -> System -> Advanced System Settings -> Advanced -> Environment Variables and in System variables modify the PATH variable. Add C:\Program Files\Java\jdk1.7.0_21\bin to the end. Be sure there’s no space at the end of the line. See screenshots below.

Save the changes, you don’t need to restart computer, but you have to reload command prompt.

There might be a problem, check if you don’t have java.exe in the C:/Windows/System32/. If the file is in this location, you should rename (or delete if you are brave) it. Reload command prompt ant type java -version to check if everything is allright.

Set JAVA_HOME and JDK_HOME variables

JDK_HOME should be enough but someone experienced a problem without JAVA_HOME, so set them both for sure.

We are going to continue. Type SET JAVA and SET JDK to command prompt to check if the variables are set up. Are they not? Ok, you should add them to the system variables. Once again – Control Panel -> System -> Advanced System Settings -> Advanced -> Environment Variables.

Add JDK_HOME and JAVA_HOME with value C:\Program Files\Java\jdk1.7.0_21\. Do you see the screenshot below? It won’t work because there’s a space left at the end of value line! Check it and save it.android-studio-fix-05

And that’s it, you are ready to go, everything should be set up and Android Studio should start right after you click the icon.

  1. I would firstly check, if there is no left blank space in JDK_HOME (or JAVA_HOME) variable – it could happen when you are copy pasting the path from website.
    Then check if there’s not java.exe in C:/Windows/System32. You should remove it (or rename it for safe). Of course, you should have latest JDK installed.
    If the Android Studio won’t start without error message, try to run the Android Studio directly from Commnad line, you will get the error message.

  2. You need to be a part of a contest for one of the highest quality blogs on the internet.

    I’m going to recommend this blog!
