Flutter 发布包或 APK 启动时崩溃，dlopen 失败：找不到库“libflutter.so”

Question

我的 debuggin apk 正在正常工作，但在模拟器 Pixel 3a api 30 中，版本在启动时崩溃

这是我在 android studio 中的错误日志

Answer 1

尝试更改 build.gradle 中的 abiFilters 位于 android/app/build

请参阅 abiFilters 的文档。

defaultConfig { 
    ndk { 
        abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a' 
    }
}

仅构建 abiFilters 中指定的平台。如果您要在 x86 计算机上构建本地模拟器，则需要

'x86', 'x86_64'

。

常见问题：排除

'x86', 'x86_64'

以防止您的应用程序可供 Play 商店中的 x86 Android 设备或机器人使用，然后无法在本地模拟器上运行您的应用程序，而物理连接的 Android 设备则可以正常构建。

Answer 2

如果你想生成appbundle，只需将其添加到：

flutter/android/app/build.gradle

defaultConfig {
    applicationId "com.example"
    minSdkVersion 21
    multiDexEnabled true
    targetSdkVersion 30
}

signingConfigs {
    release {
        keyAlias [whatever]
        keyPassword [whatever]
    }
    debug {
        [whatever]
    }
}

buildTypes {
    release {
        signingConfig signingConfigs.release
        ndk {
            abiFilters 'arm64-v8a', 'armeabi-v7a', 'x86_64'
        }
    }
}

内部 buildTypes -> release:

ndk {
 abiFilters 'arm64-v8a', 'armeabi-v7a', 'x86_64'
}

Answer 3

我尝试在物理 Android 设备中调试时遇到此错误，只需删除 android/

中的 .gradle 文件夹

Answer 4

在 android/app/build.gradle 中添加 ndk abiFilters

defaultConfig {
        applicationId "com.devsig.cloudauthenticator"
        minSdkVersion 21
        targetSdk 32
        versionCode 4
        versionName "1.0.4"
        multiDexEnabled true
        signingConfig signingConfigs.debug
        ndk {
            abiFilters "armeabi", "x86", "armeabi-v7a", "x86_64", "mips",
                    "mips64", "arm64-v8a"
        }
    }

Answer 5

就我而言，我通过从命令行运行“颤振升级”解决了这个问题。
