未运行的Flutter Android应用设置compileSdkVersion和targetSdkVersion到SD

Question

我正在尝试在新的Android设备上执行Flutter项目。

Flutter版本为1.22.4.

这里是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'
}

这里是androidmanifest。xml文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="red.faro.flutter_capenergy">
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:name=".Application"
android:label="Capenergy"
android:icon="@mipmap/ic_launcher">
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/iconpushapp" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="fcm_default_channel"/>
<activity
android:name=".MainActivity"
android:exported="true"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">

android:resource="@style/NormalTheme"
/>
<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
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>
<action android:name="FLUTTER_NOTIFICATION_CLICK" />
<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>

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

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compileSdkVersion和targetSdkVersion设置为30可以正常启动应用程序。

在旧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targetSdkVersion设置为31的应用程序>SDK 30

我能做什么?

Answer 1

在AndroidManifest.xml中，每个活动标签必须有android:exported="true"集。

更新:

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

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