Why is 'javac' -version not being recognised cmd
Community Forums/General Help/Why is 'javac' -version not being recognised cmd

| Hello, I've downloaded and installed Android Studio. Despite this javac -version returns ‘javac’ is not recognized as an internal or external command, operable program or batch file. I've set an environment variable for JAVA_HOME to C:\Program Files\Java\jdk1.8.0_101 - still no joy. I've opened the Android SDK manager and am installing 22 packages (one of which is the 4.4.2 API 19 - this may allow Monkey to see Android as a Target build) My tablet is set to developer mode, I've enabled USB debugging mode to ON... Awaiting result of the SDK Path to be populated. I did receive notification that my CPU does not support required features (VT-x or SVM). However, I presume this will not be an issue if I can get my PC to 'see' my Android tablet as a build target. I've previously had some success compiling and then uploading ADB's to the google store to subsequently download onto an old android phone - but have yet to see any android device as a target on my PC. Any suggestions appreciated. |

| environment variable: this is only useful for applications using this variable @ "javac not recognized" You might append the "PATH" variable with the URI to the javac-binary-directory. "PATH"-directories are checked if you type in a binary name and try to execute that. bye Ron |

| Thanks Ron, I've just realised I don't have ANT installed. For some reason I read the ANT requirement as simply a MAC OS thing, whoops. I'll also try your suggestion for You might append the "PATH" variable with the URI to the javac-binary-directory. "PATH"-directories are checked if you type in a binary name and try to execute that.

| Hmmm, don't know where I got the advice to attempt javac -version, java -version returns a version number. Is javac a separate entity or was that simply a typo in a set of instructions I was using ? Anyhow, finally got Android as a build option, one minor hurdle to overcome, ant is not being recognised as a command, despite having the following in my path var: %ANT_HOME%C:\Ant\apache-ant-1.9.7\bin;%JAVA_HOME%C:\Program Files\Java\jre1.8.0_101\bin Any suggestions ? |

| @ PATH And this does work? %BLA% are like variables ... so you might have myvariableC:\Ant\...;anothervariableC:\... So if %ANT_HOME% already contains "C:\Ant\apache-ant-1.9.7" you would have to have this in path: %ANT_HOME%\bin The delimeter of the entries is ";" @ ant http://ant.apache.org/manual/install.html bye Ron |

| aaah, thankyou Ron ;) I'd to truncate the /bin of the end of my ANT_HOME. |

| Google "Java Programming for Kids, Parents and Grandparents", somewhere in that ebook it shows how to set the environment variables. |

| Kool and the gang, I'm just a big kid at heart and a Parent as well. Thanks again Ron for your help - Android target compiling a treat ;) |
