Can I resign an .apk with a different certificate than what it came with?

Question

If I have an apk can I remove the current signing and some how resign it with a different .keystore file and still have the application install?

Update: I managed to get it to work with Jorgesys' solution and where I messed up before was that I unzipped the .apk then rezipped it after removing the META-INF folder and changed the file extension back into .apk. What I should have done is simply opened it with winzip and delete the folder inside of winzip.

Answer 1

try this

1)change the extension of your .apk to .zip

2)Open and remove the folder META-INF

3)change the extension to .apk

4)Use the jarsinger and zipalign with your new keystore.

hope it helps
