Unless you've dabbled in sideloading before, all of the apps on your smartphone or tablet probably came from the Play Store, Google's own app marketplace, or the official app store of your device's manufacturer, e.g., the Samsung Galaxy store. Starting today, however, you can download this new third-party app store from the Google Play Store. Aptoide Games is Google Play's first third-party app storeAs reported by The Verge, starting today, Aug. 10, you can download the "Aptoide Games" app marketplace on your Android directly through the Play Store. Google has actually allowed developers to create and distribute third-party app stores on the Play Store since July 22. Google fought the ruling, then tried to compromise with Epic Games to allow for third-party app stores—just not through the Play Store.
