Using Appcelerator Titanium with Android on 64-bit Windows 7

If anyone else is having trouble with the combo of Titanium, the Android SDK, and Windows 7 64-bit, then maybe this post if for you. It took me a few hours to get right.

Upon clicking “Android Emulator” under the Run button, I was receiving errors about jarsigner and java missing. Here’s what you have to do:

  1. Titanium requires the 32-bit version of the Java SDK, even if you are running on 64-bit Windows. Furthermore, it requires Java 6; Java 7 is the default.
  2. Uninstall all other versions of Java, and download Java 6 (which appears to be version 1.6, as opposed to Java 7 which appears as 1.7) for 32-bit from here:
  3. Install that.
  4. Set your JAVA_HOME path by following these steps: Go to your Start Menu, right click on Computer, click Properties. Click Advanced System Settings on the left, go to the Advanced tab, and click the Environment Variables… button at the bottom. Under System Variables, and click New… Name is JAVA_HOME, and value is something like C:Program Files (x86)Javajdk1.6.0_33, with the path possibly varying depending on the exact version of Java you installed.
  5. Now, add the bin directory to your PATH variable. Still in Environment Variables, under the System Variables section, find Path. Click Edit…, and in the Value box, append a semicolon if one isn’t already there. Then, append C:Program Files (x86)Javajdk1.6.0_33bin, taking note that your exact path might be a little different.
  6. Click Ok twice to get out of both dialogs.
  7. Restart your computer – yes, really. It simply won’t work if you don’t.

Side-rant: Why can’t Java configure the damn path variables for me? It couldn’t possibly be that hard to have the installer perform these two simple steps. I propose a new slogan. Java™ : Complexity for the sake of tradition.

Further troubleshooting

If you still get errors, then make sure you got all the paths to your JDK right. Actually navigate to the exact directory and copy the path from the address bar, instead of relying on the exact paths that I posted above.

If you still get errors, then make sure you have the right version of the JDK installed. Remember: 32-bit, Java 6 (1.6).
