关于android:Android进阶Android使用-flutter

1. 在其余目录中依赖 flutter SDK

plugins {
    id 'com.android.library'
    id 'kotlin-android'
}

// 在其余目录中依赖 flutter SDK
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')
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 29

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles "consumer-rules.pro"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            versionNameSuffix kotlin_version
        }
        profile {versionNameSuffix kotlin_version}
        debug {versionNameSuffix kotlin_version}
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {jvmTarget = '1.8'}
}

flutter {source '../..'}

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.2.0'
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.google.android.material:material:1.1.0'
    implementation fileTree(dir: 'libs', include: ['*.aar', '*.jar'], exclude: [])
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

2. 只打包 flutter 所反对的架构

android {
    compileSdkVersion 29

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

    lintOptions {disable 'InvalidPackage'}

    defaultConfig {// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutter_app"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        ndk {abiFilters "arm64-v8a", "x86_64", "x84" // 只打包 flutter 所反对的架构，flutter 没有 armeabi、armeabi-v7a 架构的 so, x86 是为了兼容模拟器}
    }

    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
        }
        profile {
            applicationIdSuffix flutterVersionName
            versionNameSuffix flutterVersionName
        }
    }

    packagingOptions {
        //  确保 app 与 asr_plugin 都依赖 lib/flutter.so，merge 时不抵触
        pickFirst 'lib/x86_64/libflutter.so'
        pickFirst 'lib/arm64-v8a/libflutter.so'
        pickFirst 'lib/x84/libflutter.so'
    }
}
