Abstract

Apkupdater is an open-source Mobile App Development project. APKUpdater is an open source tool that simplifies the process of finding updates for your installed apps. It provides similar functionality to an app store, but instead of depending on a single source, it aggregates the results from APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab and GitHub. It is built using Kotlin, Android, Java. Key capabilities include: Update Sources: Find updates from APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab, GitHub and Google Play; Search Sources: Find new apps to install from APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab, GitHub and Google Play; Schedule background update checks and receive a notification when updates are found. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building a Mobile App Development mini project or final-year project.
