name: Android APK (debug)

# Triggers:
#   - push v*-tauri tag → signed release APK + minisign + updater manifest → GitHub Release
#   - workflow_dispatch → signed release APK when ANDROID_KEYSTORE_* secrets exist
#     (overlay install + user data preserved); otherwise unsigned debug APK (annotated, non-blocking)
#   - workflow_dispatch + signed_debug=true — debug APK signed with the release
#     keystore (when secrets exist); artifact remains openless-android-debug-*.
#
# #1103 build-time changes:
#   - Do not wipe Cargo/Gradle/target before cache post-save (removed Free disk step).
#   - Bump rust-cache prefix-key so old half-cold caches are not reused.
#   - Dispatch defaults to aarch64 only; tag builds all ABIs in a parallel matrix.
#   - Optional dispatch fast_profile (disable LTO / raise codegen-units); tag never uses it.
#   - Tauri still runs plugin-init cargo + android-studio-script per ABI (first ABI twice).

          ### Android 安装说明

          - **推荐**：真机下载 `OpenLess_<version>_arm64-v8a.apk`（arm64 设备）。
          - **模拟器**：x86_64 模拟器用 `OpenLess_<version>_x86_64.apk`。
          - 首次安装需在系统设置中允许「安装未知应用」；应用内更新会拉起系统安装器。
          - adb 调试：`adb install -r OpenLess_<version>_arm64-v8a.apk`

          ### Android 应用内更新

          - Stable 用户检查 `latest-android-aarch64.json`（及 mirror 变体）。
          - Beta 用户（设置 → 高级 → 加入 Beta）检查带 `-beta` 后缀的 manifest。
