使用 React Native 构建 Android 应用程序时出错：依赖项的 AAR 元数据中指定的 minCompileSdk (31)

Question

I am trying to build react native project

but I got an error when running npm run android

> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
   > The minCompileSdk (31) specified in a
     dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)
     is greater than this module's compileSdkVersion (android-30).
     Dependency: androidx.appcompat:appcompat:1.4.1.

Already gone through all the solution mentioned on this , this , this , and this but could not solve it.

android/build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "30.0.2"
        minSdkVersion = 21
        compileSdkVersion = 30
        targetSdkVersion = 30
        ndkVersion = "21.4.7075529"
    }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.2.2")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.3.10'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.8.1'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        mavenCentral {
            // We don't want to fetch react-native from Maven Central as there are
            // older versions over there.
            content {
                excludeGroup "com.facebook.react"
            }
        }
        google()
        maven { url 'https://www.jitpack.io' }
    }
}

app/build.gradle dependencies

dependencies {
    implementation 'androidx.multidex:multidex:2.0.1'
    implementation fileTree(dir: "libs", include: ["*.jar"])
    //noinspection GradleDynamicVersion
    implementation "com.facebook.react:react-native:+"  // From node_modules

    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"

    debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.fbjni'
    }

    debugImplementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.flipper'
        exclude group:'com.squareup.okhttp3', module:'okhttp'
    }

    debugImplementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.flipper'
    }

    if (enableHermes) {
        def hermesPath = "../../node_modules/hermes-engine/android/";
        debugImplementation files(hermesPath + "hermes-debug.aar")
        releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

Let me know if anyone require any additional information.

Answer 1

Updated the compileSdkVersion & targetSdkVersion to 31 and added kotlinVersion = "1.7.20" in android/build.gradle

kotlinVersion = "1.7.20"
buildToolsVersion = "30.0.2"
minSdkVersion = 21
compileSdkVersion = 31
targetSdkVersion = 31
ndkVersion = "21.4.7075529"

You may have to specify REACT_NATIVE_VERSION so add these changes in android/build.gradle

def REACT_NATIVE_VERSION = new File(['node', '--print',"JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim())
allprojects {
    configurations.all {
        resolutionStrategy {
            force "com.facebook.react:react-native:" + REACT_NATIVE_VERSION
        }
    }

Add the android:exported="true" in Androidmanifest.xml in .MainActivity tag like this

<activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:launchMode="singleTask"
        android:windowSoftInputMode="adjustResize"
        android:screenOrientation="portrait"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
        android:exported="true">
