Error: style attribute '@android:attr/windowExitAnimation' not found-ThrowExceptions

Exception or error:

I recently upgraded to the gradle-3.0.0-alpha8 after which some styles are not resolved at compile time.
Develop envirment:

  • IDE: Android studio 3.0 Bate3
  • Gradle build tools : ‘’
  • Gradle

Error info:

    Error:(94, 5) style attribute '@android:attr/windowExitAnimation' not found
    Error:(94, 5) style attribute '@android:attr/windowEnterAnimation' not found

Setting android.enableAapt2=false in file can solve this isuue.

But, Instant App need android.enableAapt2=true. What would i do?

How to solve:

All the problem was solved already.

Cause of the problem:

There are two modules, A_module, B_module.

B_module has a style:

<style name="my_style”> 

If B_module compile(‘:A_module’)
Build or Clean, report a error location in A_module->Res->values->styles:

Error:(94, 5) style attribute ‘@android:attr/windowExitAnimation’ not found
Error:(94, 5) style attribute ‘@android:attr/windowEnterAnimation’ not found

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>


<item name="android:windowEnterAnimation">@anim/anim_toast_show</item>
<item name="android:windowExitAnimation">@anim/anim_toast_hide</item>


Setting android.enableAapt2=false in the file fixes this issue. See the Stack Overflow question I linked.

It will help you!


Removing a custom attribute

I got a similar error when I deleted an attribute for a custom view. The reason the error came up was that I still had xml references to it in my project.

Pressing Ctrl + Shift + F to search the entire project for the offending attribute and then removing all references to it solved the problem.
