Size of .apk file is more when packaged from command line in flex mobile app

I have a built a mobile application using flash builder burrito and when i export the app from the builder the size of the apk file is say 1180KB,but when i try packaging the same application from the command line the size increases dramatically(to 2679KB).In both the cases if we see the size of swf file it is 2679KB only.So the builder is using some compression techniques to reduce the file size.Is t开发者_Python百科here any options available in command line to do the same compression technique??.I have used the following command to package the swf file..

adt -package -target apk -storetype pkcs12 -keystore testCert.p12 projectRunTime.apk projectRunTime-app.xml projectRunTime.swf

Thanks in advance!!!

Flash Builder uses ADT to package the APK. There are no extra compression options. To find out what is going on, I suggest that you unzip both the apk files and compare the file contents.
