程序包安装错误：Visual Studio Code中失败[INSTALL_FAILED_OLDER_SDK]

问题描述

我试图构建Flutter应用程序并在设备上运行它，但出现此错误：

我在旧设备Samsung galaxy S5（SM G900I）上运行我的APP，但过去我成功在该设备上运行我的APP。 我认为我的版本在gradle或清单中有错误。 为了解决该错误并在设备上安装并运行我的应用程序，我需要做些什么？

build.gradle：

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.")
}

def FlutterVersionCode = localProperties.getProperty('Flutter.versionCode')
if (FlutterVersionCode == null) {
    FlutterVersionCode = '1'
}

def FlutterVersionName = localProperties.getProperty('Flutter.versionName')
if (FlutterVersionName == null) {
    FlutterVersionName = '1.0'
}

解决方法

将您的SDK更新到android文件夹中的最新版本 android { compileSdkVersion 30

defaultConfig {
    targetSdkVersion 30
}

}有时，当您自动更改时，无法下载 如果不起作用，请重新安装android sdk。它可以正常工作或更新sdk
