Androidx模块,未找到android:attr/ttcIndex和android:attr/fontVariationSettings

Question

我正在将所有支持/ appcompat库迁移到androidx.在所有更新之后,由于此错误,我无法构建我的项目

:app:processDebugManifest UP-TO-DATE
AGPBI: {"kind":"error","text":"error: resource android:attr/fontVariationSettings not found.","sources":[{"file":"/Users/xxx/.gradle/caches/transforms-1/files-1.1/appcompat-v7-27.1.1.aar/7cae290a69b05f5ffc25283e26a7eb4a/res/values/values.xml","position":{"startLine":250,"startColumn":4,"startOffset":27058,"endColumn":68,"endOffset":27122}}],"original":"","tool":"AAPT"}
AGPBI: {"kind":"error","text":"error: resource android:attr/ttcIndex not found.","sources":[{"file":"/Users/xxx/.gradle/caches/transforms-1/files-1.1/appcompat-v7-27.1.1.aar/7cae290a69b05f5ffc25283e26a7eb4a/res/values/values.xml","position":{"startLine":250,"startColumn":4,"startOffset":27058,"endColumn":68,"endOffset":27122}}],"original":"","tool":"AAPT"}
:app:processDebugResources

我试图逐个包含所有依赖项,以确定导致问题的原因.只有当我删除Room库¯\ _(ツ)_ /¯时才能构建

https://developer.android.com/topic/libraries/architecture/adding-components#room

这很奇怪,因为问题似乎来自造型资源,但房间只是一个数据库库.

有没有人有任何想法或解决方案,包括房间而不打破一切？

===============================

我的conf:

compileSdkVersion 27
buildToolsVersion 27.0.3

defaultConfig {
    minSdkVersion 16
    targetSdkVersion 27
}

dependencies {
    // ROOM
    implementation ('androidx.room:room-runtime:' + androidxRoomVersion)
    implementation ('androidx.room:room-rxjava2:' + androidxRoomVersion)
    implementation ('androidx.room:room-guava:' + androidxRoomVersion)
    kapt ('androidx.room:room-compiler:' + androidxRoomVersion)
}

with:androidxRoomVersion = 2.0.0-alpha1

Answer 1

设置你的compileSdkVersion 'android-P'和targetSdkVersion 28

编辑:现在compileSdkVersion 28也应该工作意味着你不再需要设置它android-P

Answer 2

将compileSdkVersion更改为'android-28'将targetSdkVersion更改为'28'
