Aligning
In my case SDK Build Tools 20 were already installed. I copied zipalign.exe in Tools folder but without success.
After that I noticed that I updated Eclipse without removing or renaming the old folder.
So I did:
1) Renamed old Eclipse folder 2) Restarted Eclipse
Eclipse asked to correct Android preferences because problem was Eclipse, that was still trying to use the old folder
