Part of the procedure for signing says:
Compiling and signing with Eclipse ADT
When using Eclipse with ADT, you can use the Export Wizard to export a signed .apk (and even create a new keystore, if necessary). The Export Wizard performs all the interaction with the Keytool and Jarsigner for you, which allows you to perform signing via a graphical interface instead of the command-line. Because the Export Wizard uses both Keytool and Jarsigner, you should ensure that they are accessible on your computer, as described above in the Basic Setup for Signing.
To create a signed .apk, right-click the project in the Package Explorer and select Android Tools > Export Signed Application Package. (Alternatively, open your AndroidManifest.xml file in Eclipse, open the Overview tab, and click Use the Export Wizard.) The window that appears will display any errors found while attempting to export your application. If no errors are found, continue with the Export Wizard, which will guide you through the process of signing your application, including steps for selecting the private key with which to sign the .apk, or creating a new keystore and private key.
When you complete the Export Wizard, you'll have a signed .apk that's ready for distribution.
But I cant see Android Tools > Export Signed Application Package
I only see Android Tools > Export Unsigned Application Package in my Eclipse.
Any ideas why so?
