    You must use the same certificate.</p>

  Please have a look in my developer console, which has both the upload certificate &amp; app signing certificate. </p>

  <blockquote>
    <p>If you lose your keystore or think it may be compromised, Google Play
    App Signing makes it possible to request a reset to your upload key.
    If you're not enrolled in Google Play App Signing and lose your
    keystore, you'll need to publish a new app with a new package name.</p>

  <p>Note: Related to KeyStore many questions on stack overflow, but this is some thing related to new feature from Google <strong>"App Signing"</strong> and i m not getting nay suitable answer.</p>
  
  <p><strong>I have contacted Google and their response is not confirming anything. Please find below message from google.</strong></p>
  
  <blockquote>
    <p>I'm sorry for the confusion, however I can see for your app (with
    package name: com.wma.foodinns.foodinnsapp), you have successfully
    registered your upload key with Google and have therefore successfully
    generated an upload key. The upload key you generated and then used to
    register is the key you should still have on your side and should be
    used to sign your APKs when uploading new APKs for this app to the
    Play Console. </p>
    
    <p>The certificate you can download from the Play Console is not the full
    upload key, but contains the public key as well as some extra
    identifying information about who owns the key (for more information
    on this, please see the definitions listed here:

    <p>Do you still have the key you have created that was then registered as
    as the upload key on the Play Console?</p>
