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?
2.8或以上
构建。gradle更新
在更新到Flutter 2.8之前
android {
compileSdkVersion 30
defaultConfig {
applicationId "com.example.app"
minSdkVersion 21
targetSdkVersion 30
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
}
更新到Flutter 2.8后:
android {
compileSdkVersion flutter.compileSdkVersion
defaultConfig {
applicationId "com.example.app"
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
你应该从慢车转车。以下属性说明:
首先进入android->local.properties
从这里开始变化
像这样改变build.gradle
android {
compileSdkVersion localProperties.getProperty('flutter.compileSdkVersion').toInteger()
defaultConfig {
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}

versionName flutterVersionName
}
所有答案都是最好的。但在Flutter 2.8之后更改SdkVersion时，以下方式是最好的:
转到安装flutter的根目录。应该是这样的
C:\src\flutter\flutter
然后转到
packages>Flutter tools>gradle>
在Gradle中，你会看到很多文件，找到flutter。gradle。右键单击它，用文本编辑器/记事本编辑它。
在这里你可以找到所有的SDK版本。更改它们，保存，然后就可以开始了
完整的路径应该是这样的:(在我的例子中)
C:\src\flutter\flutter\packages\flutter_tools\gradle
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。
