How does Google play store list apps?

Our app has been banned on Google Play and we don't understand the reason. How can we get an explanation if Google refuses to answer?

• We are a small company that developed a rather simple application that shows the users a list of tasks and tracks completion of these tasks. Similar to JunoWallet but a different one. The app had been released in May and everything was fine until a few days ago the app has been suspended in Google Play Market. The reason was described in the e-mail: "This is a notification that your application, XXXXX , with package ID YYYYYY, has been removed from the Google Play Store. REASON FOR REMOVAL: Violation of section 4.4 of the Developer Distribution Agreement. After a regular review we have determined that your app interferes with or accesses another service or product in an unauthorised manner. This violates the provision of your agreement with Google referred to above." We had no idea of could be possibly wrong, so we asked the Google if it might be a mistake, or result of miscommunication. In response I received this e-mail: "We have reviewed your appeal and will not be reinstating your app. This decision is final and we will not be responding to any additional emails regarding this removal. If your account is still in good standing and the nature of your app allows for republishing you may consider releasing a new, policy compliant version of your app to Google Play under a new package name. We are unable to comment further on the specific policy basis for this removal or provide guidance on bringing future versions of your app into policy compliance. Instead, please reference the REASON FOR REMOVAL in the initial notification email from Google Play." Great but not really helpful. I'm not even sure where to ask or if I'm ever allowed to ask anything how to fix the app. The list of tasks is provided by a famous global vendor that's integrated into thousands of apps, so it might not be the problem. The only idea we have regarding possible "unauthorised access" is that the app scans the list of installed packages to detect fraud with BlueStacks emulators. But this action doesn't require special authorization, and there are lots of application in the Play market that scan installed apps, even specialised ones, like "App List Backup".  We even could delete this functionality, if we were sure that it's a problem. I'm pretty sure that we are not the only one who fell in such situation. Does anyone have any experience on how to work this out? Is it possible to approach Google and get practically useful feedback?

• Answer:

  A better place to ask this would be on the XDA forums. While I sympathize with your situation, you will get a lot more Android focused people there.
