Flutter APK 无法在 Android 13 上安装

Question

我有一个 flutter 项目，我构建了用于安装的 apk，但我无法在 android 13 上安装它，但它已安装并在 android 14 上完美运行。

我的设备上也有足够的存储空间，并且还启用了来自未知来源的安装。 当我尝试在 Android 13 上安装它时，它只是说应用程序未安装。

这是我的

app/build.gradle

：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 34

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    aaptOptions {
        cruncherEnabled = false
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.vpn_app"
        minSdkVersion 16
        targetSdkVersion 34
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

这也是我的

mani/AndroidManifest.xml

：

    package="com.example.vpn_app">

         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->

Answer 1

android {
namespace "xx.xxx.xxx"
compileSdkVersion flutter.compileSdkVersion
ndkVersion flutter.ndkVersion

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

defaultConfig {
   applicationId "xx.xxx.xxx"
    minSdkVersion 21
    targetSdkVersion 34
    compileSdkVersion 34
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

buildTypes {
    release {
        
        signingConfig = signingConfigs.release
    }
}

}

你可以这样尝试吗

 minSdkVersion 21
    targetSdkVersion 34
    compileSdkVersion 34

 and 

android {
namespace "xx.xxx.xxx"
compileSdkVersion flutter.compileSdkVersion
ndkVersion flutter.ndkVersion
 

它是我的 build.gradle 文件并且工作正常
