java.lang.SecurityException when install apk

Question

as you know apk is a zip archive, I extracted it and replaced some resources, and zipped it again, when I install it, I get this exception

java.lang.SecurityException: META-INF/MANIFEST.MF has invalid digest

any solution for this error??

I came across this same error caused by having installed the JDK 7 instead of 6. Hope it helps some other people with this error.

If you're signing yourself with jarsigner and have JDK 7 you can add the options "-digestalg SHA1 -sigalg MD5withRSA" to the jarsigner command and it will work with JDK7. – gravitron Feb 04 '12 at 15:12

Thanks! This is exactly what happened. – Randy Sugianto 'Yuku' Feb 13 '12 at 04:14
gravitron - Thanks for the informational and helpful comment! This is a better answer since you don't have to downgrade your SDK – MitziMeow Mar 03 '13 at 04:42

Did you sign it after re-packing it? Changing anything in it broke the existing signature.

If the package is already installed and you re-sign the new one with a different signing key, it will also refuse to install.

My problem was wrong certificate alias in keystore. I changed it to "CERT" and it started to work. I used this command: keytool -changealias -alias "1" -destalias "CERT" -keystore android.jks
