android app rejected

Dear all,

Can anyone help me and explain what it actually means:

Unfortunately your submission Original Tattoo isn’t ready for CodeCanyon and cannot be resubmitted as it did not meet our minimum requirements for quality and/or Envato Market policies. In order for submissions to be considered for sale they must be of high aesthetic and technical quality, unique to our library and cannot be in violation of Envato’s policies.

Regrettably the Help and Quality Teams are unable to offer a critique or feedback on your rejected submission.

I don’t understand envato team about this rejection, I think my app is clean enough to make it approved !

Any idea about this?
