颤振Android应用程序未运行设置将SDK版本和TargetSDK版本编译为SDK 31

Question

我正试图在一个新的Android设备上执行一个Flutter项目。

颤振版本为1.22.4。

这里有app/build.gradle文件：

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 plugin: 'com.google.gms.google-services'
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 31

    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 "red.faro.flutter_capenergy"
        minSdkVersion 23
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

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

    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.release
            minifyEnabled true
        }
    }

    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.release

                }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation platform('com.google.firebase:firebase-bom:27.0.0')
    implementation 'com.google.firebase:firebase-messaging'
}

这是AndroidManifest。xml文件

            <meta-data

              android:resource="@drawable/launch_background"
              />


            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter>

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>


        </activity>
        <activity
            android:name="com.yalantis.ucrop.UCropActivity"
            android:screenOrientation="portrait"
             android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

    </application>

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
</manifest>

在新的Android设备（SDK 31）上启动应用程序时，调试器会显示以下错误消息：

Error: ADB exited with exit code 1

Performing Streamed Install


adb: failed to install /Users/modestovascofornas/Desarrollo/2022-G2-CAPENERGY-FLUTTER-PROFESIONAL/FLUTTER/flutter_capenergy/build/app/outputs/flutter-apk/app.apk: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl644805330.tmp/base.apk (at Binary XML file line #80): io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]

Error launching application on sdk gphone64 x86 

将CompileSDK版本和targetSdkVersion设置为30确实可以按其应有的方式启动应用程序。

在较旧的设备上执行应用程序完全没有问题。

唯一的问题是在Android设备上启动compileSdkVersion和Target etSdkVersion设置为31的应用程序

我该怎么办？

Answer 1

在AndroidManifest.xml中，每个活动标记都必须设置< code > Android:exported = " true " 。

更新：

<activity
        android:name="com.yalantis.ucrop.UCropActivity"
        android:screenOrientation="portrait"
         android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

自

<activity
        android:exported="true"
        android:name="com.yalantis.ucrop.UCropActivity"
        android:screenOrientation="portrait"
         android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
