Amazon will close its Appstore for Android devices effective August 20. New app submissions will not be accepted, but developers can update existing apps until the deadline. The Appstore, operational in 200 countries, primarily serves Amazon devices. After the closure, previously downloaded apps may not function on Android devices. Amazon will also discontinue its virtual currency, Amazon Coins, with refunds for unused coins after the deadline. The Appstore will continue to operate on Amazon's proprietary devices, such as Fire TV and Fire Tablet.
