Zipalign Tool- Verification FAILED

Hi,
if you are getting message like Verification FAILED while working with manually zipalign your apk, then it may be the problem of your path for the output file,

You may wrote the command like below

./zipalign -c -v 4 /Users/Downloads/app_old.apk test1.apk;

but it totally wrong from zipalign tool

Write the above command as below

./zipalign -c -v 4 /Users/Downloads/app_old.apk /data/subfolder/test1.apk;

and it will work.

Its because zipliagn tool not allowed to write the output file on the same destination.
