【问题描述】：

美好的一天，我尝试为 android 和 ios 制作一个带有通知的简单天气应用程序，为此我使用基本的 Flutter 应用程序和库 flutter_local_notifications: ^0.5.1+2 和 location: ^2.0.0，但同时使用它们时出现错误：

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

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:preDebugBuild'.
> Android dependency 'androidx.core:core' has different version for the compile (1.0.0-rc01) and runtime (1.0.1) classpath. You should manually set the same version via DependencyResolution

我尝试使用其他地理定位库，但经常遇到类似的错误

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

对于geo_location_finder 库

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

对于geolocator 库

我应该怎么做才能制作我的天气应用程序？

【问题讨论】：

首先，迁移到AndroidX

如何制作？

我将android.useAndroidX=true 和android.enableJetifier=true 添加到grandle.properities。该项目仍然使用每个库单独构建，但两者都会产生一个新错误：

Execution failed for task ':app:preDebugBuild'. > Android dependency 'androidx.versionedparcelable:versionedparcelable' has different version for the compile (1.0.0-rc01) and runtime (1.0.0) classpath. You should manually set the same version via DependencyResolution

迁移到 AndroidX 最简单的方法是打开 Android 项目并使用 Refactor 菜单。此外，您的问题可能是因为您的插件使用 AndroidX，而其他插件没有，在这种情况下，您必须分叉有问题的插件并修复它以使其使用 AndroidX

【参考方案1】：

不开玩笑，我最近遇到了同样的问题（我收到了很多关于 AndroidX 的各种依赖项的投诉，以 -rc01 版本结尾），并且用于强制解决策略的各种解决方案都不起作用。

我通过在 android/build.gradle 文件中升级我的 gradle 依赖项解决了这个问题：classpath 'com.android.tools.build:gradle:3.3.1'（我之前使用的是 3.2.1 版）

【参考方案2】：

我遇到了来自 androidX 兼容性的相同问题。错误消息如下所示：

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

我修复如下（如果相同，忽略它）：

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

在 android/build.gradle

依赖 类路径 'com.android.tools.build:gradle:3.3.0'

在 buildscript 下（如果它包括 kotlin）

ext.kotlin_version = '1.3.0'

在 android/gradle.properties 中，追加

android.enableJetifier=true

android.useAndroidX=true

在 android/app/build.gradle：

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

...

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

依赖项下

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'

默认配置下

multiDexEnabled 真

希望这会有所帮助！！！

【讨论】：

这很有帮助。正如 Prakhar 在另一个答案中所说，com.android.tools.build:gradle:3.3.1 版本可能是解决方案的关键。
