railslave for signing apk I made a desktop shortcut having the target like this:
"C:\Program Files (x86)\Java\jdk1.6.0_38\bin\jarsigner.exe" -verbose -keystore C:\Android\user.keystore C:\Android\app.apk user
copy your unsigned apk to c:\Android (or any other location) and rename it to app.apk (or any other name)
Takes 1 click and 10 sec to sign.
P.S. I have 4 shortcuts for decompile, compile, sign and zipalign
I use decompile apk to remove one of the 2 armeabi library that cocoonjs offer. that way the file size is 5MB smaller
