Question

我正在尝试从flutter应用程序构建apk，但出现此错误：

我用Google搜索，发现compileSdkVersion必须为28。这是我的构建gradle应用程序：

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "net.mobile"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

但是我仍然有错误吗？

而且看来您没有适用于Linux的库。

On Debian/Ubuntu/Mint: sudo apt-get install lib32stdc++6

On Fedora: dnf install libstdc++.i686
