Keytool command in Java?

Question

I have spent multiple hours trying to figure out the keytool CLI command for Java (in order to zipalign my Android app).

After a long search, I saw on another Stack Overflow Question that I should verify that I have the filepath, and after confirming the path to the binary was correct, I tried to check for the keytool; this is what happened:

 C:\Users\ealeo_000>dir "C:/Program Files (x86)/Java/jre1.8.0_73/bin/keytool.exe"

 Volume in drive C has no label.
 Volume Serial Number is 70C4-072A

 Directory of C:\Program Files (x86)\Java\jre1.8.0_73\bin

 File Not Found

According to what I've looked up, this should be the correct path; yet nothing is showing up. This leads me to believe that for some reason that keytool is not being installed along with the JDK...

Am I correct in assuming this? If so, how do I fix this?

Answer 1

You're showing a path to a JRE, the Java runtime environment, not a path to a JDK, the Java development kit. You need to download & install the JDK and then make sure it is used before the JRE.

Note that there are two Program Files and Program Files (x86) on 64 bit Windows machines where the Java installations may reside.
