解决发布版APK构建失败的问题

事实证明，处理此问题的最佳方法是在中进行以下更改android/app/build.gradle：

android {
compileSdkVersion 26
buildToolsVersion '26.0.3'
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
applicationid "com.example.app"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
// This is the main section that I've updated
// to get the release APK to build
buildTypes {
release {
profile {
matchingFallbacks = ['debug', 'release']
}
signingConfig signingConfigs.release
}
}
}
flutter {
source '../..'
}
dependencies {
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'


通过此更改，我能够构建发行版APK。
