Question

我正在尝试使用Flutter构建适用于Android的应用程序捆绑包，但是当我运行flutter build appbundle时，我一直收到这些错误。

CloudFirestorePlugin.java uses or overrides a deprecated API.
WebViewActivity.java uses or overrides a deprecated API.
Gradle build failed to produce an Android bundle package.

在我的/app/build.gradle中，我无法解析符号'Properties'，'GradleException'或'FileInputStream'。代码：

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"

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

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 "XXXXX"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    signingConfigs {
       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile file(keystoreProperties['storeFile'])
           storePassword keystoreProperties['storePassword']
       }
   }

    buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-auth:19.2.0'
    implementation 'com.google.firebase:firebase-firestore:21.3.0'
    implementation 'com.google.firebase:firebase-analytics:17.2.1'
}

apply plugin: 'com.google.gms.google-services'

在/app/src/main/AndroidManifest.xml中，我得到了Unresolved Class UCropActivity。代码：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="XXX">

    <uses-permission
        android:name="android.permission.INTERNET"/>
    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="XXX"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name="com.yalantis.ucrop.UCropActivity"
            android:screenOrientation="portrait"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

我遵循了https://flutter.dev/docs/deployment/android上的所有步骤，但是找不到CloudFirestore不推荐使用的API标志或未解析的符号的任何解决方案。不确定构建发行包时是否存在问题。感谢您的帮助，我的iOS应用已准备就绪，但仍无法使用Android版本。

使用Flutter构建适用于Android的应用程序包时出错？
