* Possible errors

This error is normally cause by the mismatch of the information of application.
Check you run “signed” test app. Unsigned app (which has debug certificate) won’t be recognized as correct application.
Check the version code. the one in AndroidManifest shoule be the same as the currently uploaded apk’s versionCode
