Question

这是我第一次在应用程序中安装Android_intent插件，在实验过程中，我在简单的应用程序中安装了插件，并且插件运行良好，但是当我在应用程序中执行相同的操作时，我实际上有了一个插件，更长的时间。但是当我安装它时，出现了这样的错误：

我已经尝试了好几天。我的代码错了吗？有人能帮我吗？谢谢最好的问候。

Answer 1

将此代码添加到项目的android构建Gradle文件中。

subprojects {
project.evaluationDependsOn(':app')
project.configurations.all {
    resolutionStrategy.eachDependency { details ->

        if (details.requested.group == 'androidx.core'
                && !details.requested.name.contains('androidx')) {
            details.useVersion "1.0.1"
        }


      }
   }
}

在再次尝试之前，请不要忘记清理项目。

我只是在另一个插件上遇到了同样的问题，却发现很少有用的信息。最终对我有用的步骤是：

升级gradle版本：
- 在android/gradle/wrapper/gradle-wrapper.properties中，我切换为使用5.4.1
- 在android/build.gradle中，我切换到classpath 'com.android.tools.build:gradle:3.5.1'
确保使用了AndroidX支持库：
- 在android/app/build.gradle中，这是将所有android.support前缀切换为androidx.support（和分别将com.android.support切换为com.androidx.support的问题。

根据我的实验，我认为是问题的根本原因是＃2-的确，步骤1可能是完全不必要的，但是当我试图找出原因时似乎是一个合理的起点。问题是。

由于您没有提供有关gradle属性的信息，因此我只能基于遇到的构建问题的相似性来假设您面临类似的问题。
