Qidi

Qidi is an Android/Shizuku tool for tracing and defending background apps on aggressive OEM Android builds.

Initial goals:

• Let the user choose apps that should keep running in the background.
• Reapply Doze whitelist, App Standby bucket, and AppOps protections through Shizuku.
• Trace termination incidents with ApplicationExitInfo, package stopped state, ActivityManager event logs, and nearby OEM process state.
• Show honest evidence about whether an app was force-stopped, background-killed, or killed by ordinary memory pressure.

This repository started from investigation of a TCL Android device where protected apps repeatedly reached stopped=true and ActivityManager recorded FORCE STOP / KILL BACKGROUND exits from system_server.
