Missed my private signing file for Android

Question

I made an Android App and posted it in Android market, and now I'm made some updates on my Apps and trying to give a next version of the same app. The problem is I missed my KeyStore file I generated previously. But I'm having my old vesion APK file. Now I'm not able to upload the next version, the developer console says

The apk must be signed with the same certificates as the previous version. 

as error. May I get any help to make new version for my android app now..?

Answer 1

There's currently no way of retrieving a lost signing key. What you can do is get a new one, pull your app from the market, and upload your update using a different package name.

Answer 2

Sorry, as far as i know you are not allowed to update your application now.

To update existing application on market, you must have that KeyStore file and also remember the password.
