无法找到属性android:font for v7 support

Question

我一直在开发一款Linphone应用程序,但却陷入了困境.我已经更改了应用名称并重构了所有相关包.应用程序没问题,直到我将gradle升级到3.0.0.

AGPBI: {"kind":"error","text":"error: resource android:attr/fontStyle not found.","sources":[{"file":"~/.gradle/caches/transforms-1/files-1.1/support-compat-27.0.0.aar/61646c6d4479aff22f7047873e2edd7d/res/values/values.xml","position":{"startLine":20,"startColumn":4,"startOffset":1254,"endColumn":69,"endOffset":1319}}],"original":"","tool":"AAPT"}
AGPBI: {"kind":"error","text":"error: resource android:attr/font not found.","sources":[{"file":"~/.gradle/caches/transforms-1/files-1.1/support-compat-27.0.0.aar/61646c6d4479aff22f7047873e2edd7d/res/values/values.xml","position":{"startLine":20,"startColumn":4,"startOffset":1254,"endColumn":69,"endOffset":1319}}],"original":"","tool":"AAPT"}

我已经阅读了有关无法找到属性错误但无法找到答案的其他问题.我尝试了下面的方法,但没有一个工作:

1. 删除应用程序的bin /目录
2. 清理缓存并再次重建应用程序
3. 使缓存无效并重新启动(其中的每个选项)
4. 更改sdk版本(api)
5. multiDexEnabled true/false

以下是日志的详细信息:

Answer 1

要解决这个问题,你应该:

1. 安装mathching SDK版本(27)
2. 在模块中,build.gradle您应该设置compileSdkVersion为27并更改com.android.support:appcompat-v7版本以匹配com.android.support:recyclerview-v7:(或您使用的其他支持库组件)版本(27.0.0)

UPD:

如果由于某种原因它对您没有帮助,请参阅下面的评论 @madu

Answer 2

我遇到了同样的问题.只需调整compileSdkVersion和buildToolsVersion即可.

这是以前的版本:

这是没有问题的版本:

Answer 3

我能够通过将以下值更新为'27'来解决此问题:

android {
    compiledSdkVersion 27

    defaultConfig {
        targetSdkVersion 27
    }
}

Answer 4

也许卸载并重新安装整个 android studio 会有所帮助...记住备份您的项目。
