Question

我正在尝试在我的flutter应用程序中实现map_view，但是当我提供依赖项然后运行该应用程序时，它显示了一些错误。而且，我不知道该如何解决。

我的错误：- *运行Gradle时出错： ProcessException：进程“ D：\ development \ flutter \ flutter_course \ android \ gradlew.bat”异常退出：

配置项目：map_view 警告：指定的Android SDK Build Tools版本（27.0.3）被忽略，因为它低于Android Gradle Plugin 3.2.1的最低支持版本（28.0.3）。将使用Android SDK Build Tools 28.0.3。要取消显示此警告，请从build.gradle文件中删除“ buildToolsVersion '27 .0.3'”，因为每个版本的Android Gradle插件现在都具有默认版本的构建工具。 ****************************************************** ******* 警告：如果此版本的shared_preferences或其依赖项与AndroidX不兼容，则会破坏您的Android构建。此警告会针对所有Android构建失败进行打印。错误的真正根本原因可能无关。 ****************************************************** *******

失败：构建失败，并出现异常。

出了什么问题： Android Gradle插件仅支持Kotlin Gradle插件1.2.51及更高版本。项目“ android”正在使用版本1.1.2-4。

我的build.gradle：-

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-4'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的pubspec.yaml文件：-

description: A new Flutter project.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
   - assets/race.jpg
   - assets/bg.jpg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: Oswald
      fonts:
        - asset: assets/Oswald-Bold.ttf
          weight: 700
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro

  #       - asset: fonts/TrajanPro.ttf

Answer 1

将您的kotlin版本更改为1.2.51

  classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.51

然后在app-> buildGradle中检查targetSdkVersion，如果低于28，则将其更改为28

让我知道是否有问题
