Why Sideloaded Android Apps Don’t Normally Auto-Update
Sideloaded Android apps give you freedom—access to beta builds, region-locked features, and custom forks that never hit the Play Store. The trade-off is maintenance. Unlike Play Store apps, which enjoy automatic Android background updates, sideloaded apps typically require you to find every new APK, download it, and reinstall manually. That’s tedious and easy to forget, especially if you rely on multiple third‑party sources like GitHub, F-Droid, or developer websites. The root issue is permissions: only app stores with special system privileges can silently install updates. Ordinary apps, even update managers, must show an installation prompt for every APK. Until recently, that meant APK auto-update for sideloaded apps just wasn’t practical. Today, a mix of open-source tools solves this. Downloaders like apkeep help you mirror store builds, while update managers such as Obtanium can track releases and, with elevated permissions, install updates in the background—bringing sideloaded apps closer to Play Store convenience.
Step 1: Use Obtanium to Track and Fetch Updates
Obtanium is a free, open-source updater designed specifically to auto-update sideloaded apps. Once installed, it acts as a central hub that monitors multiple sources—GitHub, F-Droid, APKMirror links, and other supported repositories—for new releases. Instead of manually checking each project page, you add your apps as “sources” and let Obtanium handle the polling in the background. To get started, install Obtanium from its official website or GitHub repository, choosing the build that matches your CPU architecture (armv7 or universal will suit most devices). Open the app and tap the “+Add App” tab. You can search by name across several catalogues or paste a direct repository URL. For example, if you sideload a keyboard like Heliboard from GitHub, add its repo URL and Obtanium will list available releases and offer a one-tap install. From then on, Obtanium periodically checks for updates and sends a notification whenever a new APK is available for your tracked apps.

Step 2: Configure Obtanium for Seamless APK Auto-Updates
After adding your apps, refine Obtanium so Android background updates are reliable and safe. First, open each app entry and ensure the correct release type and CPU architecture filters are selected. Many GitHub and GitLab projects publish multiple builds; choosing the proper architecture ensures you always get a compatible APK. Next, visit Obtanium’s settings to configure how often it scans for updates. Shorter intervals mean faster updates for bleeding‑edge users, while longer intervals reduce background activity. You can also set whether downloads should occur only on Wi‑Fi, helping you control data usage. Obtanium will now notify you whenever an update appears. The first time you install an update, Android will prompt you to grant Obtanium permission to install apps from unknown sources. Approve this so Obtanium can handle future installs. For easier device migration, use the Import/Export tab to save your app list; importing it on a new phone recreates your entire sideloading setup in one step.
Step 3: Enable Silent Background Installs with Shizuku
By default, Obtanium still needs you to tap through each installation dialog, which is less convenient than the Play Store. To fully auto-update sideloaded apps, you can grant Obtanium elevated install permissions using Shizuku, another free, open-source tool. Shizuku leverages Android’s wireless debugging feature to delegate certain privileged operations—like installing apps—to trusted user apps without rooting your device. Install Shizuku from the Play Store and enable Developer Options on your phone if necessary. In Developer Options, open Wireless Debugging, choose “Pair device with pairing code,” and enter the six‑digit code in the Shizuku notification. Once pairing succeeds, return to Shizuku and tap “Start” to launch its service. Under “Authorized applications,” enable Obtanium. Finally, in Obtanium’s settings, toggle “Use Shizuku (or similar) to install.” From then on, when updates are available, Obtanium can download and install them silently—no confirmation dialogs, just true background APK auto-update for your sideloaded Android apps.
Step 4: Keep Sideloaded and Store Apps in Sync with apkeep
If you juggle both official store installs and sideloaded builds, you may want parity between them. This is where apkeep, an open-source command-line Android package downloader, can help. Apkeep lets you fetch APKs directly from major app providers, including the Play Store and F-Droid, using device profiles so you receive the same app variant your phone would normally download. With apkeep, you can automate retrieving app packages for testing, research, or backup. Researchers already use it to download thousands of apps for large‑scale analysis, and privacy projects integrate it to inspect how apps behave across versions. For power users, combining apkeep with an update manager like Obtanium means you can script regular downloads of new builds from trusted stores, then let Obtanium handle installation. This workflow keeps your sideloaded Android apps closely aligned with official releases, while still giving you the flexibility to experiment with custom builds, beta channels, or regional variants without losing automatic update convenience.
