Can anyone tell me how to zipalign my .apk file with using eclipse. I have made my .apk file by giving command like,
Right Click on Project Folder
Click on "Android Tools" option from menu.
Click on "Export Signed Application Package..." and my .apk generated in given application alias.
Now want to do zipalign for this above generated .apk file. Does any tool require to do so OR anything that can solve my problem.
If you did what you described above then Eclipse has already zipaligned your apk for you. You can't zipalign an already zipaligned package
I think this will help you
D:\android-sdk\android-sdk\tools>zipalign -f -v 4 "C:\Users\name\Desktop\project_name\projectname_signed.apk" "C:\Users\name\Desktop\project_name\projectname__zipaligned.apk"
Using the steps given, Eclipse will do zipalign for you.
This is a very tricky part and initially i was also ran in to strange problems . Before uploading to android market you must do the following steps.
- Create a Certificate
- Signing your application apk
- Finally Zip align the signed apk

zipalign is basically a tool available in tools directory of your android sdk.
In case you are not using eclipse to build, you can use this tool directly to zipalign your apk.
zipalign [-f] [-v] <alignment> infile.apk outfile.apk
The alignment is an integer that defines the byte-alignment boundaries. This must always be 4 (which provides 32-bit alignment) or else it effectively does nothing.
