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?
我在我的flutter应用程序中设置Auth0、flutter_appauth和flutter_secure_storage时遇到了这个问题。在更改minSdkVersion版本后，我得到了这个错误
C:\Users\myusername\AndroidStudioProjects\wole\android\app\src\debug\AndroidManifest.xml Error:
Attribute data@scheme at AndroidManifest.xml requires a placeholder substitution but no value for <appAuthRedirectScheme> is provided.
FAILURE: Build failed with an exception.
问题出在哪里:
任务“:app:processDebugManifest”执行失败。
清单合并失败:AndroidManifest.xml中的属性data@scheme需要占位符替换，但没有提供for的值。
解决方案就是这样添加manifest占位符
这里详细的解决MinSdk / MinSdk版本错误的方法，按照下面的步骤进行。
在android\local.properties中添加以下行
sdk.dir=
flutter.sdk=C:\\flutter
flutter.buildMode=debug
flutter.versionName=1.0.0
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=31
flutter.compileSdkVersion=31
删除现有的行，并将其粘贴到应用程序级别构建。gradle: android \ app \ build.gradle
defaultConfig {
applicationId "app-id"
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
