Are you using Eclipse or Android Studio? Here are the steps for Android Studio as I do not use Eclipse: 1: export to Android from BB 2: open Android Studio and select Import Project 3: Find the exported file from BB and import. Go through all the screens by choosing ok until your project opens 4: Once you are inside Android Studio select the tab at the top that says Build and choose Generate Signed APK 5: Create a keystore by following the steps you see on the screen. OR if you already have a keystore then just choose the location, enter your username and password 6: Once you have completed that hit next and build the APK. 7: Send the APK to your friend and he can install it directly onto his device Cheers
Here is EVERYTHING you need to make a APK for an Android device, it takes a little bit to get everything going, but once you do, it only takes a few minutes to take a saved BB file and turn it into an APK These files are everything you need to and theres even video tutorials as well : https://www.dropbox.com/sh/fdp2g9h1hdjnq9u/AABbAR-riAo3L0B5RdzQyqZqa?dl=0
