嗨,我正在开发应用程序。当我尝试建立抖动时,会出现错误Unable to merge dex
。
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.")
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {
compileSdkVersion 27
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.xyz"
minSdkVersion 16
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
}
}
flutter {
source '../..'
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

}
apply plugin: 'com.google.gms.google-services'
buildscript {
ext.kotlin_version = '1.1.51'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.0.0'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
}
有人知道如何解决它吗?
答案 0 :(得分:3)
尝试在应用程序build.gradle中添加它
android {
defaultConfig {
multiDexEnabled true
}
}
更改
classpath 'com.google.gms:google-services:4.0.0'
implementation 'com.google.firebase:firebase-core:16.0.0'
到
classpath 'com.google.gms:google-services:4.0.1'
implementation 'com.google.firebase:firebase-core:16.0.1'
并在Android Studio和 清洁, 重建或只是运行flutter clean命令
答案 1 :(得分:0)
执行以下步骤:
flutter clean
flutter build
重建或使用flutter run
运行。我希望这会有所帮助。
答案 2 :(得分:0)
遵循此link后,为我解决了一个非常相似的问题。
**我不必将multiDexEnabled设置为true
首先,我将pubspec.yaml中的依赖项设置为
dependencies:
flutter:
sdk: flutter
cloud_firestore: ^0.8.2
并在我的IDE终端中运行flutter packages get
。
我还必须更改最低目标SDK版本:
仅此一项就可以解决您的问题;但是,我还必须执行以下操作,因为某些依赖项版本不匹配。
我必须打开android/app/build.gradle
,然后将以下行添加为文件的最后一行:
apply plugin: 'com.google.gms.google-services'
接下来,我必须打开android/build.gradle
,然后在buildscript标记内,添加一个新的依赖项:
buildscript {
repositories {
// ...
}
dependencies {
// ...
classpath 'com.google.gms:google-services:3.2.1' // new
}
}
此后,我的应用终于在android模拟器上运行了。
如果遇到困难,link的演练会更完整。
