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

This issue occurred for me when I had my project's bin folder open in Windows Explorer.

I then tried to delete my old apk file (which the Export tool was unsuccessfully trying to overwrite), but I couldn't do that as I didn't have the necessary permission or because some other process had a lock on the file.

The solution was to restart my computer which released the lock on the apk file. Eclipse's Export tool then worked fine.

Update Could not delete the old apk file in Windows Explorer or in Command window (even when I opened it with Admin rights), but I could delete the apk when viewing it in my FileZilla FTP client application. Obviously, this is much more convenient than restarting the computer.
