Google签名APK在Android 12L设备上崩溃问题求助

问题现象 #

• 预发布阶段的Google签名APK在Android 12L设备上启动后立即崩溃，弹出带错误信息的黑色窗口；本地构建的debug、release包无此问题
• 普通手机/平板设备运行正常，涉事Android 12L设备未安装Google Play商店
• 全新平板设备完成Google账号配置后可正常使用应用
• Firebase Crashlytics未捕获到该崩溃报告

错误日志 #

执行adb logcat *:E获取到以下关键错误：

同时出现库文件缺失错误：

java.lang.RuntimeException: java.util.concurrent.ExecutionException: com.getkeepsafe.relinker.MissingLibraryException: Could not find 'libflutter.so'. Looked for: [arm64-v8a, armeabi-v7a, armeabi], but only found: []

原项目build.gradle配置（release构建类型） #

buildTypes {
    debug {
        signingConfig signingConfigs.debug
    }
    release {
        signingConfig signingConfigs.release
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile(
                'proguard-android-optimize.txt'),
                'proguard-rules.pro'
        ndk {
            debugSymbolLevel 'FULL'
        }
    }
}

解决方案 #

在release构建类型的ndk配置中添加abiFilters，明确指定应用支持的ABI架构：

buildTypes {
    debug {
        signingConfig signingConfigs.debug
    }
    release {
        signingConfig signingConfigs.release
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile(
                'proguard-android-optimize.txt'),
                'proguard-rules.pro'
        ndk {
            debugSymbolLevel 'FULL'
            abiFilters "armeabi-v7a", "arm64-v8a", "x86_64"
        }
    }
}

添加该配置后，libflutter.so缺失问题解决，同时Android 12L设备上的崩溃问题也一并消失。

问题分析 #

1. 核心崩溃原因是Google签名APK构建时未包含目标Android 12L设备对应的ABI架构库文件，导致libflutter.so加载失败引发崩溃；
2. 涉事设备未安装Google Play商店导致License校验失败，但该错误并非崩溃触发点，解决ABI适配后，License相关错误未引发崩溃（推测代码中存在容错处理逻辑）。
