What's the best Android app for installing APK files on Fire Stick?

Downloader by AFTVnews is specifically designed to address the limitations of Amazon's Fire OS ecosystem, where users frequently need to install applications from outside the official app store. The app functions as both a web browser and file manager, allowing users to navigate to APK download sources directly from their Fire TV device. Once the APK file downloads, the app automatically prompts for installation, eliminating the need for complex workarounds or additional tools. This streamlined approach proves particularly useful for installing media players, utility apps, or alternative app stores that aren't available through Amazon's curated selection. Users report the interface remains intuitive even when navigating with a remote control, though some note that keyboard support could be more robust for entering lengthy URLs. The app's popularity within the Fire TV community stems from its reliability in handling various APK versions and its ability to organize downloaded files for future reinstallation. While occasional compatibility issues arise with certain APK files, the app generally provides a stable method for expanding Fire TV functionality beyond Amazon's ecosystem restrictions.
