报错：Error: style attribute '@android:attr/windowExitAnimation' not found]
style文件中

<style name="AnimationActivity">
        <item name="@android:activityOpenEnterAnimation">@anim/left_in</item>
        <item name="@android:activityOpenExitAnimation">@anim/right_out</item>
        <item name="@android:activityCloseEnterAnimation">@anim/right_in</item>
        <item name="@android:activityCloseExitAnimation">@anim/left_out</item>
    </style>

把@去掉

 <style name="AnimationActivity">
        <item name="android:activityOpenEnterAnimation">@anim/left_in</item>
        <item name="android:activityOpenExitAnimation">@anim/right_out</item>
        <item name="android:activityCloseEnterAnimation">@anim/right_in</item>
        <item name="android:activityCloseExitAnimation">@anim/left_out</item>
    </style>

报错：
java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2error: check logsfordetails
解决方案: 在项目根目录下 gradle.properties 文件中添加如下行(关闭AAPT2)
android.enableAapt2=false
