实施material.io时出错-为什么这样做？

Question

每当我添加实现'com.google.android.material：material：1.0.0'并尝试构建我的项目时，它都会失败：

AGPBI: {"kind":"error","text":"error: resource android:attr/ttcIndex not
 found.","sources":[{"file":".gradle/caches/transforms-1/files-1.1/appcompat-v7-27.1.1.aar/d7c317b06402f0d32ee3cf13363bbddb/res/values/values.xml","position":{"startLine":250,"startColumn":4,"startOffset":27058,"endColumn":68,"endOffset":27122}}],"original":"","tool":"AAPT"}
:app:processLocal1DebugResources :app:processLocal1DebugResources
FAILED FAILURE: Build failed with an exception.
  * What went wrong: Execution failed for task ':app:processLocal1DebugResources'.
Failed to process resources, see aapt output above for details.

这是我的gradle脚本：

apply plugin: 'io.fabric'

keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
