我正在尝试为一个使用蓝牙通信的应用程序启动一个颤振项目。我用的是颤振蓝。
不幸的是，当试图运行(在Android设备上)我创建的第一个示例时，我遇到了以下错误:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:flutter_blue] /home/maldus/Projects/flutter/polmac/build/flutter_blue/intermediates/manifests/full/debug/AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 19,
or use tools:overrideLibrary="com.pauldemarco.flutterblue" to force usage (may lead to runtime failures)
如果我在Android Studio，我知道如何提升Android minSdkVersion，但在一个flutter项目(使用VSCode)，我有点迷失。
是否有可能增加minSdkVersion与颤振，以及如何?
对于颤振v2.8
在当地。属性添加
sdk.dir='<path>'
flutter.sdk='<path>'
flutter.buildMode=debug
flutter.versionName=1.0.0
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=30
flutter.compileSdkVersion=30
app-level build.gradle
defaultConfig {
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
现在可以使用localProperties.getProperty()从属性文件中读取值。
使用新的Flutter项目(2.8.0)，使用“Flutter样式”，您可以在本地更改最小sdk版本。属性(而不是编辑app/build。gradle文件)。
# android/local.properties
flutter.minSdkVersion=19
查看android/app/build。Gradle文件，你会看到这样的变量约束:
# android/app/build.gradle
android {
defaultConfig {
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
}
