  • are you using the same certificate to sign the app? – benka Oct 14 '14 at 14:40
  • use same key store as you created while uploading your apk first time. –  Oct 14 '14 at 14:42

You need to sign the app with the same certificate as your original app. Thats how Google Play verifies that it is an authentic app, and not malicious.

When you export an app, you sign it with a keystore. If you want to upload a new version of your app, you must upload it using the same keystore.

You need to check the 'build.gradle (module:app)' file and you need to increase 'versionCode' for new update version.
