Are you using CLI or PGB to build?
What version do you use?
I asked for the version, too.
June 2015, Google started rejecting apps built with anything lower than PGB5.x, for security reasons.
Thank victor, i figured it out myself, searched here and there on internet found the problems with my version in config.xml. updated it and solved the issue . thanks for your help. may god bless you
thank you all for help,
Issue: Google doesnot allow PGB before 4.1.1 version
i replaced the version with following code
<preference name="phonegap-version" value="cli-6.3.0" />
It solved the issue
