About
Manager is a system-level activity, permission, and task monitoring tool for Android, developed by the anonymous developer Sadpainy. It is mainly used to inspect and manage the state of running applications on a device.
It is released as open source on GitHub, aimed at users and developers interested in how low-level system mechanisms work.
Main Features
Task and activity monitoring
View the running task stack in real time. Displays the Activity structure of each task, including the current foreground interface and task ownership.
Permission overview
Lists all permissions requested by installed apps, distinguishing normal, dangerous, and system signature permissions, and showing their grant status.
App list
Shows a complete list of installed applications on the device, including package name and basic information.
Permission switcher
Based on the AppOps mechanism, displays adjustable permission and operation switches. Allows users to view or modify certain app permission states.
Shell terminal
Built-in command-line terminal based on the native /system/bin/sh and toybox. Can execute basic system commands.
Documentation
Includes built-in license, privacy policy, and project documentation. Explicitly states that no data is collected and nothing is uploaded.
What's New in 3.1
Wireless ADB connection
Adds a Settings panel supporting Android wireless debugging pairing, granting higher operational privileges without modifying the system partition.
Underlying architecture upgrade
Introduces Kotlin, OkHttp3, and Okio, and implements a complete ADB protocol stack including pairing, port detection, ROM adaptation, and security checks.
Usage & Permission Strategy
Normal mode
Install the APK directly and run with basic permissions. You can view the app list, permission overview, and task activity, but cannot execute operations that require system-level privileges such as dumpsys.
Advanced mode
Obtain wireless ADB debugging authorization, or install the APK into the system partition at /system/priv-app/, to gain higher privileges and fully use the tool's capabilities.
