大家好，我遇到了一个特别棘手的问题，想向各位求助：我的Android应用在绝大多数设备上都能正常运行，但有部分三星Galaxy A12（Android 12）用户反馈，应用一启动就直接崩溃，连闪屏界面都没机会显示，更麻烦的是Crashlytics完全捕获不到这些崩溃的日志，导致我根本没办法定位问题根源。

受影响设备信息 #

• 设备型号：三星Galaxy A12
• Android版本：Android 12

核心问题 #

应用启动瞬间崩溃，闪屏界面无法展示，常规崩溃报告工具完全抓不到有效日志，调试陷入僵局。

已尝试的调试方案及结果 #

1. ABI兼容性排查 #

一开始我怀疑是ABI架构不兼容的问题，于是在app/build.gradle中配置了多架构支持：

android {
    defaultConfig {
        ndk {
            abiFilters 'armeabi-v7a', 'arm64-v8a'
        }
    }
}

结果：重新构建并发布后，问题依然存在。

2. ProGuard/R8混淆排查 #

我猜测可能是代码混淆破坏了关键类，于是更新了ProGuard规则，甚至直接禁用混淆做测试：

buildTypes {
    release {
        minifyEnabled false // 也试过配置正确的ProGuard规则
    }
}

结果：即使关闭混淆，崩溃问题还是没有解决。

3. Firebase测试实验室验证 #

我在Firebase测试实验室中使用同款三星Galaxy A12（Android 12）设备进行了测试。
结果：应用能正常启动并运行，完全没有出现崩溃情况。

当前状态 #

• Crashlytics：受影响设备的崩溃日志完全没有记录
• 其他设备：应用运行一切正常
• 测试实验室：同款设备型号测试无异常
• 唯一相关崩溃记录：在Crashlytics中发现一条ABI相关崩溃，但来自Pixel设备，并非三星Galaxy A12
