java - Android studio(gradle) 版本兼容性

Question

我有这个问题。 Android studio(Gradle) 版本兼容性问题。谁能帮我解决这个问题。下面提到了我使用的所有依赖项版本。我认为这是一个版本问题。试了很多。但是无法解决。你能帮我么。我能做些什么来解决这个问题。

项目级 Gradle 文件:

Android 资源链接失败并出现下一个错误:

C:\Users\isufernando\Desktop\New folder\demo-firebase-android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2476: error: resource android:attr/fontVariationSettings not found.
C:\Users\isufernando\Desktop\New folder\demo-firebase-android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2476: error: resource android:attr/ttcIndex not found.
error: failed linking references.

Answer 1

resource android:attr/fontVariationSettings not found.
resource android:attr/ttcIndex not found.

将 compileSdkVersion 更改为:

compileSdkVersion 28

fontVariationSettings和 ttcIndex在 api level 28 中添加。

你也在用

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

Firebase 在最新版本中迁移到了 AndroidX。这意味着您同时使用了支持库和 androidx 库。

您可以:

• 如下所述迁移到 androidx
• 降级你的 firebase 依赖项(但这不是真正的解决方案，因为你必须在之前或之后迁移)

您可以查看 official release notes :

Warning: This release is a MAJOR version update and breaking change. The latest update to Google Play services and Firebase includes the following changes:

从 Android 支持库迁移到 Jetpack (AndroidX) 库。除非您在应用中进行以下更改，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。
• 将compileSdkVersion升级到28或更高版本。
• 更新您的应用以使用 Jetpack (AndroidX)；按照 Migrating to AndroidX 中的说明进行操作.
