Android 添加Firebase核心版本17.0.0后，清单合并失败

我将firebase crashlytics依赖项添加到我的项目中，之后项目不会生成

你能建议一下我可能做错了什么吗

谢谢 R

构建在这些行上失败

implementation "com.google.android.gms:play-services-base:17.0.0"
implementation 'com.google.firebase:firebase-core:17.0.0'

这是错误日志

问题是最新的firebase依赖项已迁移到androidx。因此，一个修复方法是将您的项目迁移到androidx，请参阅（我更喜欢这样做，因为所有新的升级都使用androidx）。或者，您可以将firebase core依赖项降级到以下版本

implementation 'com.google.firebase:firebase-core:16.0.9'

1。问题似乎是因为使用了来自两个类的相同支持库。
-（android.support.v4.app.CoreComponentFactory）来自[com.android.support:support compat:28.0.0]
-（androidx.core.app.CoreComponentFactory）来自[androidx.core:core:1.0.0]。
2.如果可能，移除包含android支持库的库；使用“gradlew依赖项”进行检查。
3.或者使用androidx支持库仅删除类似的库
编译“com.android.support:appcompat-v7:28.0.0”
编译“com.android.support:support media compat:28.0.0”
编译“com.android.support:support-v4:28.0.0”
您使用“编译”而不是“实现”的具体原因是什么？
4.或者根据错误转储建议进行更改：将“tools:replace=“android:appComponentFactory”添加到元素

Hi应该更改com.google.android.gms的版本：play services base:17.0.0是的，您也必须对其进行降级，但请记住，我建议迁移到androidx在将来会更有帮助。降级对我来说很有效。我在上查看了每个firebase库，并选择了不高于2018年5月的最新版本。除了降低firebase，还有其他需要降级的内容吗？您必须降级所有使用Androidx的库。但是我强烈建议你去AndroidX有什么解决办法？@SeanMC，我研究这个问题已经很久了。请告诉我您面临的错误以及相应的详细信息（工具/环境的版本）。无需担心。我升级到androidx，它就消失了
