# Tigris v2.0.15 — 主页键回到 Tigris / Home returns to Tigris

## 中文

- **遥控器上的主页键不再受自动接管次数限制。** 以前按主页键和开机时的自动切回共用「30 秒内 3 次，然后暂停 60 秒」。暂停时主页键也会停在原厂桌面。现在主页键、系统的 homekey 广播，以及小米 Android 12 及以上在 Tigris 被切走时的立刻切回，都不受这个次数限制。
- **开机头三分钟的自动来回跳仍会停住。** 这是为了避免和原厂桌面抢画面（雷鸟 75S545C，issue #14）。看不到前台、正在使用的应用或 HDMI 不会被拉回 Tigris。
- **持续过滤主页键。** Android 12 及以上可在设置中打开，默认关闭。开启后所有按键经过桌面守护，部分应用可能按一次走两下。小米不提供这项，主页键会在 Tigris 暂停时切回。
- **安装与修复。** 小米/红米、TCL/雷鸟、酷开/创维、海信会打开桌面守护；索尼和 Google TV 仅在原厂桌面的 HOME 优先级大于 0 时打开。先登记 HOME 角色，再设置默认桌面。新增 `repair`：已安装后重新授权守护，不卸载、不关闭原厂桌面。前台检查读取 `mFocusedApp`。
- **安装说明。** 官网增加「按主页键还是原来的」：小米闪一下是正常的、如何运行 repair、在设置里重新打开桌面守护、Android 13 允许受限设置、待机后按一次主页键，以及目前修不好的机型（例如会反复清掉无障碍的雷鸟 75S78A Plus、坚果 S621）。不要自己关掉自带桌面。

### 安装与验证

Android 9+，versionCode **21**（上一版为 20）。沿用现有包名和正式签名，支持覆盖升级，保留布局、设置、应用数据及 Standard/Guard 类型。无需卸载。不关闭原厂桌面。

两种安装包的构建、单元测试、静态检查、安装器测试和网站检查已通过。没有在真电视上按遥控器、待机或重启验收。安装成功不等于主页键、待机或开机已经接管。

## English

- **A Home press is no longer limited by the automatic-takeover budget.** Home used to share “3 times in 30 seconds, then pause for 60 seconds” with boot retries, so the remote could leave the factory launcher in front. The Home key, the system homekey broadcast, and Xiaomi’s Android 12+ pause bounce are not counted.
- **Automatic retries during the first three minutes are still capped.** That stops a boot fight with the factory launcher (Thunderbird 75S545C, issue #14). An unknown front, an open app, or HDMI is left alone.
- **Keep filtering the Home key.** Optional on Android 12 and newer, off by default. Every key then passes through the guard, and some apps may move twice for one press. Xiaomi does not offer it; Home is answered when Tigris pauses.
- **Install and repair.** The guard turns on for Xiaomi/Redmi, TCL/FFalcon, Coocaa/Skyworth and Hisense, and for Sony or Google TV only when a stock launcher’s HOME priority is above 0. The HOME role is added before the default home activity. New `repair` re-authorizes the guard without uninstalling Tigris or disabling the stock launcher. Foreground checks read `mFocusedApp`.
- **Install guide.** The website adds “Home still opens the original screen”: the expected Xiaomi flash, how to run repair, turning the guard off and on in settings, Android 13 restricted settings, one Home press after standby, and models that still cannot be fixed (for example FFalcon 75S78A Plus, which clears accessibility, and JMGO S621). Do not turn off the factory launcher yourself.

Android 9+, versionCode **21** (previous release was 20). Standard and Guard keep the existing application ID, signing identity and in-place upgrade. Settings and data are preserved. The stock launcher is not disabled.

Both flavors passed builds, unit tests, lint, installer tests and the website check. No television was used for a remote Home press, standby or reboot. A published APK is not proof that Home, wake or boot takeover works on a given set.
