快速构建 (Release)

# 1. 添加 CMake 路径修复 (必须! Windows 250字符限制)
#    在 frontend/CretasFoodTrace/android/build.gradle 的末尾添加:
cat >> frontend/CretasFoodTrace/android/build.gradle << 'GRADLE'

// CMake path length workaround (Windows MAX_PATH)
subprojects { subproject ->
    def applyCmakeWorkaround = {
        def androidExt = subproject.extensions.findByName('android')
        if (androidExt != null) {
            try {
                if (androidExt.externalNativeBuild?.cmake?.path != null) {
                    androidExt.externalNativeBuild.cmake.buildStagingDirectory = file("C:/b/${subproject.name}")
                }
            } catch (Exception ignored) {}
        }
    }
    try { subproject.afterEvaluate { applyCmakeWorkaround() } }
    catch (Exception e) { applyCmakeWorkaround() }
}
GRADLE

# 2. 清理旧 CMake 缓存
rm -rf node_modules/react-native-reanimated/android/.cxx

# 3. 构建
ANDROID_HOME="C:\\Users\\Steve\\AppData\\Local\\Android\\Sdk" \
JAVA_HOME="C:/Program Files/Java/jdk-17" \
cmd //c "cd frontend\CretasFoodTrace\android && gradlew.bat assembleRelease"

# 4. 复制到项目根目录
cp frontend/CretasFoodTrace/android/app/build/outputs/apk/release/app-release.apk ./CretasFoodTrace.apk

# 5. 清理 CMake 临时目录 + 恢复 build.gradle
rm -rf C:/b
git checkout frontend/CretasFoodTrace/android/build.gradle
