Amazon will close its Appstore for Android devices on August 20 of this year, and developers will no longer be able to submit new applications. The decision is part of a strategic shift to enhance user experience on Amazon's own devices. The Appstore will still be available on Amazon's Fire TV, Fire Tablet, and other built-in products. Developers can submit updates for existing applications until the service ends. Additionally, Amazon will discontinue its Amazon Coins program on the same date and will refund any remaining coins in user accounts.
