title: Can I re-sign an .apk with a different certificate than what it came with?
body: <p>If I have an apk can I remove the current signing and some how re-sign it with a different .keystore file and still have the application install?</p>
  
  <p><strong>Update</strong>: 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.</p>
