style attribute '@android:attr/windowEnterAnimation' not found

[linq8261]

我项目相关的配置：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-milestone-1-all.zip

classpath 'com.android.tools.build:gradle:3.0.0-alpha6'

compile_sdk_version = 25
build_tools_version = "26.0.0"

报错信息：

style attribute '@android:attr/windowEnterAnimation' not found
style attribute '@android:attr/windowExitAnimation' not found

相关代码：

<style name="FadeInPopWin">
    <item name="android:backgroundDimEnabled">true</item>
    <item name="@android:windowEnterAnimation">@anim/pop_win_content_fade_in</item>
    <item name="@android:windowExitAnimation">@anim/pop_win_content_fade_out</item>
</style>

Solution:
Removing the "@" at the start of the item name.
<item name="@android:windowEnterAnimation">@anim/anim_toast_show</item> <item name="@android:windowExitAnimation">@anim/anim_toast_hide</item>
to:
<item name="android:windowEnterAnimation">@anim/anim_toast_show</item> <item name="android:windowExitAnimation">@anim/anim_toast_hide</item>
