I have installed Android studio 3.0.1 and when i run the app he gives me an error
Error running App: No JDK specified
Note that i have installed JDK 9 and I made two environment variable JAVA_HOME and JDK_HOME and edit path variable
and in project structure I choose JDK 9 but I am also failed to run!!

Try following, it did work for me:
Go to File -> Project Structure -> SDK Location and check if the path for SDK and JDK location specified by you is correct. If its not then set the correct path.
For me it looks like this:
Android SDK location:
C:\Users\JDoe\AppData\Local\Android\Sdk
JDK location:
C:\Program Files\Android\Android Studio\jre
