Google(s goog) is abusing its dominance in the Android app distribution market to shut out rivals, the independent app store provider Aptoide has argued in an antitrust complaint to the European Commission.

According to Portugal’s Aptoide, which claims to be the largest independent Android app store with 200,000 titles and 6 million active users, Google has made it difficult or impossible in multiple ways for Android users to choose alternative app stores. CEO Paulo Trezentos told me the company had a meeting with European Commission representatives last week in preparation for the complaint’s submission, but those representatives didn’t give Aptoide any feedback at the time, in line with protocol.

Aptoide has 4 complaints:

• Blocking: A non-compete clause in the Play Store terms and conditions means no fully-functional third-party app store can be found in the Play Store. The app stores that are in there are therefore “nothing more than catalogs”…
