3 months ago Is anyone there? I still progressing this problem. I don't know if this is related to the issue, but here is my java version information:
$ java --version
openjdk 18.0.1 2022-04-19
OpenJDK Runtime Environment (build 18.0.1+10-24)
OpenJDK 64-Bit Server VM (build 18.0.1+10-24, mixed mode, sharing)Hey, I have good news!
I was able to run it successfully by adding the following line to android/app/build.gradle:
multiDexEnabled true to defaultConfigimplementation "androidx.multidex:multidex:2.0.0" to dependenciesThis is final code:
plugins {
id "com.android.application"
id "kotlin-android"
id "dev.flutter.flutter-gradle-plugin"
}
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
android {
namespace 'com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample'
compileSdkVersion rootProject.ext.compileSdkVersion
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample"
minSdkVersion flutter.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled 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.
minifyEnabled true
shrinkResources false
signingConfig signingConfigs.debug
}
}
}
flutter {
source '../..'
}
dependencies {
implementation "androidx.multidex:multidex:2.0.0"
}
I don't know why I need to explicitly enable multiDexEnabled true when running on this PC even though the sdkVersion is specified as 34, but anyway, it worked this time, so I'm happy with it. Does anyone know more about this?

2 months ago Yes, this solution works, but I suggest adding an example or a readme to inform new users about this common issue.

2 months ago The /example is simply going to implement multidex with two simple lines of code.

2 months ago multidex implemented in /example and merged to master.
