ShizuTools
Contains many tools to control android system via shizuku
ShizuTools is an Android utility suite that leverages elevated system access via Shizuku to provide controls that normally require ADB, root, or OEM-only privileges. Instead of being a single-purpose app, it bundles several focused tools under one umbrella, making it easier to apply advanced tweaks without constantly switching apps or writing commands by hand. A major use case is system app management, where the Debloater tool helps uninstall or disable preinstalled components and surfaces app information to guide safer decisions. It also includes tools that change day-to-day behavior, like enforcing picture-in-picture for apps that don’t expose it, enabling multiple audio streams at once, and giving per-app audio controls beyond what Android typically allows. For power users and automation fans, it offers shells that can execute raw ADB-style commands directly, including an intent-driven mode designed to be triggered by automation apps like Tasker or MacroDroid. -

Fuel
The easiest HTTP networking library for Kotlin/Android
Fuel is the easiest HTTP networking library for Kotlin/Android. We offer maven and jitpack installations. Maven via bintray only has stable releases but jitpack can be used to build any branch, commit and version. Have patience when updating the version of fuel or building for the first time as jitpack will build it, and this may cause the request to jitpack to time out. Wait a few minutes and try again (or check the status on jitpack). Fuel requests can be made on the Fuel namespace object, any FuelManager or using one of the String extension methods. If you specify a callback the call is async, if you don't it's blocking. Fuel and the extension methods use the FuelManager.instance under the hood. You can use this FuelManager to change the default behavior of all requests. -

Proton Authenticator for Android
Official Android implementation of a modern two-factor authentication
Proton Authenticator for Android is Proton’s official Android implementation of a modern two-factor authentication (2FA) app, designed to generate secure, time-based one-time passwords (TOTPs) and support multi-account authentication workflows with strong privacy and encryption features. The app enables users to link 2FA tokens for their online accounts, scan QR codes, and generate rotating verification codes that enhance login security across services that support TOTP standards. Built with native Android tooling and following modern design conventions, it integrates with Android’s notifications and system UI while maintaining local encryption of stored secrets so that authentication tokens are never exposed in plaintext outside the device. It also supports backup and encrypted sync with the associated Proton account, helping users recover 2FA codes across devices — a feature that many standalone token generators lack without risking security trade-offs.
