I am getting this message: The apk must be signed with the same certificates as the previous version. I read this: enter link description here

But here is my dilemma. This app was created by another developer. So i have all the files from him. Now i updated the app i am trying to upload it to market its giving me this error. Is there anyway to get this from project files i have from previous version of the app? By what name will this file be saved on the previous version? How can i reuse it.

U have to get the release key for 1st version of that application. Otherwise u cant put into that app into the market. Because for all version of same app it requires same release key.

  • It will be with the previous developer. Just ask him – Jyosna Dec 01 '11 at 06:01
  • He has given me all the file and the whole folder for the app. Any idea what should i look for to see if i already have it? – NoviceMe Dec 01 '11 at 06:02
  • check there any file like name--->appname-release-key.keystore – Jyosna Dec 01 '11 at 06:44
  • Do i just need the release-key file or do i need the password of that keystore also? Where will i add this file on my new folder? – NoviceMe Dec 01 '11 at 15:06
  • no its no need to add anywhere. Bcz to put an app into the market we need a signed apk, for that we need that key. So just use that key to create signed apk from ur apk. and put into the market. Thats it – Jyosna Dec 05 '11 at 05:38
