Question

我有这个问题。Android Studio(Gradle(版本兼容性问题。任何人都可以帮助我解决这个问题。我使用的所有依赖项的所有版本如下所述。我认为这是一个版本问题。尝试了很多。但无法解决。你能帮我么。我该怎么办来解决这个问题。

Answer 1

资源android：atter/fontvariationsettings找不到。
资源Android：找不到attr/ttcindex。

将compileSdkVersion更改为：

compileSdkVersion 28

fontVariationSettings和 ttcIndex添加在API 级别28 中。

您也在使用

implementation "com.google.firebase:firebase-auth:18.1.0"

Firebase在最新版本中迁移到Androidx。这意味着您都在使用，支持库和Androidx库。

您可以：

• 如下所述迁移到Androidx
• 降级您的firebase依赖性(但这不是真正的解决方案，因为您必须在或之后迁移(

您可以检查官方发行说明：

警告：此版本是 Major 版本更新和打破更改。 Google Play服务和Firebase的最新更新包括以下更改：

从Android支持库迁移到JetPack(Androidx(库。除非您在应用程序中进行以下更改，否则库将无法工作：

• 将com.android.tools.build:gradle升级到v3.2.1或更高版本。
• 升级compileSdkVersion至28或更高版本。
• 更新您的应用用于使用JetPack(Androidx(;按照迁移到Androidx的说明。
