Google maps does not work after resigning an apk

I am doing some modification in an existing apk that i got from my client to modify. I have decompiled application using apktool, changed some resources (like some strings from strings.xml) and recompiled/built it again using same tool. Then I signed using one_click_signer tool that I found somewhere of the google.

But when I install it on my device then google maps does not work anymore as it was working with original apk on the same device.

I have searched a lot about this but did not got any solution. I reviewed this link and many more and come to conclusion that I need to sign the apk with same key that was in original apk.

So can anyone please tell me:

  1. how can I sign the apk again with the same key and make map work?
  2. or is there any other way to make maps work properly?

Solution That I found and worked for me:

Thanx for @apmartin1991's answer . .

I created a google api console project and got got the generated key. then I replaced that key in android-manifest.xml file and resigned the application.

It worked.

Solution

  • You will need to contact your client to get the .keystore file so you can sign it with the same key OR you can sign it with your own key and allow your key to be used with google maps, You can do this from the Google API console.

    However if your clients app is on the appstore and you want to update that you MUST use the same key or it will be impossible to update it.
