flutter使用flutter_local_notifications和位置包出现错误“ Android依赖关系'androidx.core：core'具有不同的版本”

Question

美好的一天，我尝试制作一个带有android和ios通知的简易天气应用程序，为此，我们使用基础flutter应用程序和库flutter_local_notifications: ^0.5.1+2以及location: ^2.0.0，但同时使用它们会出现错误：

Launching lib\main.dart on SM A520F in debug mode...

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

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:
  #  - images/a_dot_burr.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see

  # 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: Schyler

我尝试使用其他地理位置库，但经常出现类似以下错误

D8: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver

用于geo_location_finder库

要么 WARNING: This version of device_info will break your Android build if it or its dependencies aren't compatible with AndroidX.

用于地理定位器库

我应该做些什么来制作我的天气应用程序？

Answer 1

别开玩笑，我最近遇到了同样的问题（并且我对AndroidX的各种依赖项（带有-rc01版本结尾）的抱怨越来越多），并且强制解决策略的各种解决方案都行不通。

我通过升级android / build.gradle文件中的gradle依赖关系来解决它：classpath'com.android.tools.build:gradle:3.3.1'（我以前使用的是3.2.1版）

Answer 2

我遇到了来自androidX兼容性的相同问题。错误消息看起来像：

android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.1) classpath

我将其修复如下（如果相同，请忽略它）：

1. 在android / gradle / wrapper / gradle-wrapper.properties中，更改以distributionUrl开头的行，如下所示：

distributionUrl = https：//services.gradle.org/distributions/gradle-4.10.2-all.zip

2. 在android / build.gradle中

依赖项{classpath'com.android.tools.build:gradle:3.3.0'}

• 在buildscript {下（如果包含kotlin）

ext.kotlin_version ='1.3.0'

3. 在android / gradle.properties中，追加

android.enableJetifier = true

android.useAndroidX = true

4. 在android / app / build.gradle中：

在android {下，确保compileSdkVersion和targetSdkVersion至少为28。

...

testInstrumentationRunner“ androidx.test.runner.AndroidJUnitRunner”

根据依赖{

androidTestImplementation'androidx.test：runner：1.1.1'

androidTestImplementation'androidx.test.espresso：espresso-core：3.1.1'

实现'com.android.support:multidex:1.0.3'

在defaultConfig {

multiDexEnabled是

希望这会有所帮助！！！
