在颤振应用程序中包含firebase_storage的最佳方法是什么？

Question

我需要在Firebase中存储几个文件。我在使用android仿真器。问题是:当我将包包含在yaml (firebase_storage)中时，我得到了一个很大的错误，比如下一个：

FAILURE: Build failed with an exception.

我尝试在我的颤振项目中设置一个防火墙项目，遵循google官方页面给出的步骤。我也尝试将这些代码添加到我的android/gradle中：

subprojects{
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
            && !details.requested.name.contains('multidex')) {
                details.useVersion "26.1.0"
            }
        }
    }
}

目前，我无法运行我的应用程序，因为这一点。我想知道在防火墙中存储文件的最佳方法是什么。

考虑遵循这个codelab，或者阅读这里，以防你错过了一个步骤。(google-services.json或SHA密钥等)

如果您都设置好了，那么它可能与AndroidX有关。

当您检查changelog.md时，您会在版本0.9.0上看到一个破坏更改。

尝试通过使用AndroidX来避免以前的软件包，或者将您的项目迁移转换为AndroidX。
