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?


当前回答

    **android/local.properties**
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=30
flutter.compileSdkVersion=31

  **android/app/build.gradle**
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()

targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName

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
}

按照以下步骤更改minSdkVersion问题。

第一次= > YouProject_name / android / app / build.gradle

Second=> defaultconfig{//你可以在build中找到它。gradle}

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.umair.product_details_using_crud"
        minSdkVersion 16 // here you can change minSdkVersison
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

它在[project_name]/android/app/build.gradle的defaultconfig中找到。defaultconfig

从Flutter 2.8开始,设置minSdkVersion, targetSdkVersion和compileSdkVersion略有不同。现在gradle文件在your_flutter_app/android/app/build。Gradle路径是这样的:

只需将当前值替换为您想要的版本号,如下所示:

现在运行你的颤振项目,就这样。

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
