System Tool is a Shizuku-powered Android utility designed to manage installed applications, preserve background accessibility services, and monitor hardware telemetry. It allows users to hide running apps from the multitasking overview and stop aggressive system kills without requiring root access.

Technical Overview of System Tool

The application performs elevated actions through Shizuku by calling the removeTask API to detach selected applications from the Android recent tasks list. To prevent background termination of accessibility services, it writes system parameters via settings put secure while running a ContentObserver paired with 15-second interval checks and screen-unlock broadcast triggers. Background persistence is enforced by assigning RUN_IN_BACKGROUND permissions and registering target packages into system battery restriction whitelists.

Core Features of System Tool

Recent task hiding: Strips selected packages from the recent apps view via the removeTask API and extracts installed APKs to storage.
Accessibility service protection: Prevents automated system kills using ContentObserver listeners, 15-second scheduled checks, and device-unlock triggers.
Hardware telemetry monitoring: Tracks real-time multi-core CPU frequencies, memory usage, network rates, battery health, and high-drain process rankings.
On-device ADB executor: Runs preset and custom shell commands directly with elevated privileges to view execution output.

Compatibility & Quick Setup

Requires Android 8.0 (API 26) or newer — install the APK and grant permissions via an active Shizuku service.
