You should have received an email from Google containing the reason for the suspension. Read this email to determine what needs to be changed. If you're not sure how to resolve the issue, forward the email to firstname.lastname@example.org for assistance.
If you wish to appeal to the suspension you can do so by filling out the app appeal form on the following page: https://support.google.com/googleplay/android-developer/contact/appappeals
If you wish for us to re-submit your app to the Google Play Store as a new app, please let us know. Please note that it is likely that the app will be suspended again if you re-submit it without making any changes. Multiple app suspensions may cause your Google Play developers account to be terminated.
Additionally, if you wish for us to re-submit your app while another version of your app is already suspended, a name change of the app will be required.
