Application key, jarsign and zipalign how to ?

I made an web application called association in Dreamweaver CS5.5. The files in the com.air.association_Android/bin are:


1. association.ap_

2. association.ap_.d

3. association.debug.apk (I have tested this file on my device and it is working fine.)

4. association-debug-unaligned.apk

5. association-debug-unaligned.apk.d


Now how do I make the following:


1. Generate a key

2. jarsign the app

3. zipalign the app


for publishing in Google Play.


I am confused about which file to select from the above list and the exact steps.


Please help.
