android-package-diagnostics

Everything you can learn about an installed app without touching its UI and without root. scripts/pkgdiag.py (standard library only) distils dumpsys package — over 700 lines for a single app — plus logcat, meminfo and gfxinfo into a short structured report.

Non-root is the operating constraint, not an oversight: Google Play emulator images are release-signed, so adb root is unavailable. Everything here is chosen to work under that limit.
