EmptyThrowable錯誤Android Studio中的運行

Question

我試圖通過Android Studio中運行我的應用程序，但是我收到一個錯誤：

13:02:50 EmptyThrowable 
    Invalid stub element type in index: 
    file: file://C:/Users/d_mas/AppData/Local/Android/sdk/sources/android-25/java/util/Calendar.java 
    psiElement: PsiImportList 
    requiredClass: interface com.intellij.psi.PsiClass 
    actualClass: class com.intellij.psi.impl.source.PsiImportListImpl 
    virtualFile: size:106178; stamp:0; modCount:1499594398217; fileType:JAVA; language:JAVA 
    document: size:106178; stamp:0; committed:true; saved:true 
    psiFile: size:106178; stamp:0; class:com.intellij.psi.impl.source.PsiJavaFileImpl; language:JAVA 
    stubInfo: created in getStubTree(); with backReference 
    indexing info: no data 

編譯SDK版本是25，構建工具版本25.0.3， MinSdk版本15並編譯'com.android.support:appcompat-v7:25.0.0'。我正在使用JDK 1.8。

嘗試「無效緩存/重新啓動」選項在文件菜單中。
