Error while running zipalign

Question

I got this error when trying to export a signed apk in Eclipse

Error while running zipalign: Unable to open as zip archive

I have run the Help->Check for Updat

Answer 1

For mac

Because the result of encoding does not match you must do this:

1. open eclipse.ini
2. add -Dfile.encoding=utf-8

Answer 2

I removed the apk file in the Deploy directory and the export worked fine then.

Answer 3

Sometimes a simple \ instead of a / in the destination file path can lead to this. Double check your multiplatform ant files!

Answer 4

I was getting the same error message. Drove me crazy until i found that my destination path was invalid.

Zipalign will give you that error even if the apk is perfectly valid, but

• the path to the apk is invalid
• the destination is invalid or does not exists
• the permissions are invalid (apk is locked by other program)

Answer 5

Adding on my solution:

My problem was that my assets folder was too large, and must have been messing with the zipping somehow. I had to remove files in the asset folder (or add them to _pre_production).

Answer 6

I had the same problem with my zipalign command. Output path was correct but the folders did not exist which was provided in the output path and so i created the folders manually and then it all worked fine.
