I trying publish my app to live testing. But every time I submit the APK for store review, it fails in 6-8 days and then I would receive the following message from the Distribution Team:
We noticed your submitted Android APK was unable to be successfully processed by our app ingestion systems in order to make the app available on our Amazon Appstore. The submitted APK was missing the classes.dex file containing the code to execute for your app. Please verify your application contains code and the APK contains the classes.dex file. If you are trying to push static content into our catalog (i.e. skins) we recommend using our In-App Purchasing API.
We are sorry for the inconvenience,
1. What is wrong with my app can you help? My app works but Amazon
ingestion systems said that something wrong.
2. How I can check with ingestion system before publishing?
