Sign your application
Before you can distribute your applications for use on a BlackBerry PlayBook tablet or a BlackBerry 10 device, you must first sign them. The signing process adds cryptographic hash values to your .bar files that help verify the authorship of your application to users and to the BlackBerry Tablet OS or BlackBerry 10. After your .bar files have been signed, you can add them to the BlackBerry World storefront.
- In Eclipse, in the Project Explorer navigation window, locate the Android project that you want to sign.
- Right-click the project and select BlackBerry Tools > Sign for BlackBerry World.
If the signing process is successful a signed .bar file is created in the dist > Android 2.3.3 folder with a lock added to its icon.
