Chromium Android正式构建搜索崩溃：缺失libcrashpad_handler_trampoline.so

问题背景 #

构建Android版Chromium，遵循官方指南生成APK，所用GN参数如下。随后通过Android Studio专属指南生成包装器项目，提取Java、XML、SO等资源后直接构建，App可正常启动，但执行任何URL搜索（包括chrome://version这类内置URL）时崩溃，核心报错为找不到libcrashpad_handler_trampoline.so。debug构建目录中存在该文件，但正式构建（is_debug = false）时缺失。

所用GN参数 #

target_os = "android"
target_cpu = "arm64"
android_channel = "stable"
is_debug = false
is_official_build = true
is_component_build = false
is_clang = true
symbol_level = 0
blink_symbol_level=0
use_unofficial_version_number = false
v8_use_external_startup_data = true
icu_use_data_file = false
ffmpeg_branding = "Chrome"
proprietary_codecs = true
exclude_unwind_tables = true
chrome_pgo_phase = 0

解决方案 #

• 显式启用Crashpad：在GN参数中添加use_crashpad = true和enable_crash_reporter = true。正式构建中Crashpad默认启用，但自定义参数组合可能导致构建系统排除依赖库，显式声明可确保libcrashpad_handler_trampoline.so被编译并打包。
• 检查Android Studio打包配置：确认包装器项目的build.gradle中，sourceSets.main.jniLibs.srcDirs指向Chromium构建目录下的out/[build-name]/lib/arm64-v8a，确保所有SO文件被完整引入，避免手动提取时遗漏。
• 验证构建产物完整性：用unzip命令解压Chromium官方生成的APK，检查lib/arm64-v8a/目录下是否存在目标SO文件，确认后再同步到Android Studio项目，避免资源丢失。
• 调整符号表级别：当前symbol_level = 0会完全移除符号表，可能触发构建系统的激进优化导致库被误删。可尝试将symbol_level改为1（保留最小符号表）验证问题是否解决；若必须保持symbol_level=0，需显式将crashpad_handler_trampoline加入强制链接列表。
