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

very true. In eclipse, no further process is required since the export wizard zip aligns the apk automatically. – Saunder 5/12, 2014 at 8:14

But only if you export a signed apk. An unsigned apk will not be aligned – Ynes 8/8, 2016 at 12:43

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"

@Tamawy : Here 4 stands for <alignment> that must be always be 4 (which provides 32-bit alignment) or else it effectively does nothing.You can refer "developer.android.com/tools/help/zipalign.html" – Ampereturn 24/7, 2014 at 6:30

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

Eclipse zipalign APKs when you export them by default.

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.

If you to signed and zip aligned your APK file, so that you could redistribute your file and upload it play store. Then follow these simple steps

Open Eclipse
File--> Export
Browse-->Select your project
Next-->Next

So, after all of that you will get an APK which will be signed and zip aligned.

Eclipse zipalign apk automatically. When you export the project, eclipse must be generating signed apk to a different destination. Check properly where it prompts when you generate a signed apk

Eclipse automatically zipaligns your .apk file if you did what you described above.
