mobileGF2logger — GIRLS’ FRONTLINE 2 (GF2) Platoon Manager

한국어로 된 설명은 여기에서 보실 수 있습니다.

This is a GIRLS’ FRONTLINE 2: EXILIUM (GF2) Platoon/서클 management and logging companion for the Android game client. It is Android-only; an iOS release is not planned.

mobileGF2logger is a lightweight, non-root GF2 logger for Platoon masters. It turns supported roster and activity responses into member history and weekly task tables entirely on the phone. Android’s per-app VPN permission limits capture to the fixed HaoPlay and Darkwinter game packages, and raw traffic is never stored.

Features

• Captures the mandatory Platoon Profile (21905), Members (21917), Activity (21935), and Updates (21960) responses without a computer or root access.
• Automatically separates detected Platoons by supported Android client, selected server region, and authoritative Platoon ID; switch the active isolated profile from Home, Platoon, Weekly, or Settings.
• Decodes each Platoon’s banner frame and mark from 21905 and displays the matching original in-game emblem in profile selectors.
• Tracks active and withdrawn members, non-overlapping repeat membership periods, exact Updates timestamps, editable nicknames, and private notes.
• Builds Sunday-to-Saturday Standard or Gunsmoke Frontline weekly tables around the selected server’s daily reset, with a frozen member column, a sticky day header, cut-off points, and per-day manual correction for missing data.
• Offers One-time Capture that tracks the four useful Platoon payloads and stops automatically when the checklist is complete.
• Explains every weekly cell on tap and summarizes missing or uncertain evidence in an Evidence Health panel.
• Keeps up to 15 complete automatic revisions per weekly table so an earlier projection and its displayed member context can be previewed and restored after an accidental import.
• Recovers interrupted imports before previewing roster CSV impact and keeps an automatic one-level checkpoint for undo.
• Imports a roster CSV only into an explicitly selected, already confirmed Platoon or a profile whose client, server, name, and ID the user explicitly enters. Because 21917 contains no Platoon identity, the preview always names the target and asks the user to verify it.
• Saves or shares a weekly PNG with opt-in controls for names, UIDs, and private notes.
• Can send a validated original CSV to an optional user-owned Discord incoming webhook after confirmation.
• Stores the latest 100 parsed packets and up to 50 saved packets, with table and raw views, copy, export, selection, and deletion.
• Supports member sorting, persistent drag ordering, snapshot comparison, single-week and all-week CSV export, and profile-aware .gf2backup export/restore in Settings that detects whether a backup includes app settings and leaves other Platoons unchanged.
• Keeps a newly detected Platoon’s packets in bounded memory until the user confirms one of the verified client’s compatible servers; unconfirmed data is discarded on force-stop or process death.
• Provides profile management for correcting server metadata without moving data and for deleting one isolated Platoon behind two confirmations and an exact-name check.
• Guides first-time users through Main, Settings, Platoon management, weekly controls, and parsed-packet pages, with a persistent English/Korean selector and Skip action; the guide can be replayed from Settings.
• Offers an overnight standby mode from Home’s moon button: an all-black, minimum-brightness screen that keeps the phone awake. With the optional GF2logger accessibility service turned on, standby records members by itself five minutes before each chosen server’s daily reset: it starts capture, opens the game, taps Start on the title screen, waits for the roster, closes the game from Recents, and locks the phone after the last server. The service only taps while the game is in front and reads nothing on screen except the foreground app and the app names on Recents cards.
• On a phone without a PIN, pattern, or password, can instead record every day on a schedule from Settings: an alarm wakes the phone before each chosen server’s reset, records members the same way, and turns the screen off again.
• Draws edge to edge and keeps drafts, selections, and pending exports across rotation, theme or language changes, and process recreation.
• Supports English and Korean, System/Light/Dark themes, and the six known Darkwinter/HaoPlay server-region reset presets converted to the phone timezone. Selecting a detected Platoon automatically follows that profile’s saved region.
• Registers the HaoPlay (com.haoplay.game.and.exilium) and Darkwinter (com.Sunborn.SnqxExilium.Glo) Android clients as separate VPN targets.
• Creates UTF-8 Platoon-member CSV files with this column order:

uid,name,level,weeklyMerit,totalMerit,highScore,totalScore,lastLogin,logTime

Use

1. Install the ARM64 APK on Android 8.0 or newer.
2. Open GF2logger, confirm both supported clients are installed as needed, and select One-time Capture.
3. Approve Android’s VPN prompt, then open the game.
4. Enter Platoon(서클) and open Updates(동향) and Members(멤버).
5. Return to GF2logger to review the captured packets and Platoon data.

On Android 10 and newer, Android identifies which supported game owns each captured connection. Android 8–9 can safely attribute management data only when exactly one supported client is installed; with both clients installed, unattributed management payloads are deliberately not imported. Because the plaintext protocol does not expose a trustworthy server identifier, select the correct HaoPlay and Darkwinter server in Settings before first capture.

The app keeps each confirmed Platoon’s parsed history, management data, and generated CSV files in separate private on-device storage. It does not bypass TLS, certificate pinning, or anti-cheat systems, and it does not modify game traffic. Server responses may contain only recent incremental history, so older missing membership records can be entered manually.

Reference

mobileGF2logger was inspired by blead/gfl2logger, a GF2 logger for the Windows client. This project is an independent Android implementation tailored to on-device Platoon management.

The bundled Platoon banner frame and mark sprites are original GF2 interface artwork used only to reproduce a Platoon’s user-selected in-game emblem. All rights to that artwork remain with the game’s respective rights holders.
