IndexNotReadyException - Android Studio

Question

While changing the values of a widget in properties tab, AndroidStudio keeps on throwing IndexNotReadyException. But after few minutes while retrying, the error is not occurring.

Here is the error log:

com.intellij.openapi.project.IndexNotReadyException: Please change caller according to com.intellij.openapi.project.IndexNotReadyException documentation
    at com.intellij.util.indexing.FileBasedIndexImpl.handleDumbMode(FileBasedIndexImpl.java:856)
    at com.intellij.util.indexing.FileBasedIndexImpl.ensureUpToDate(FileBasedIndexImpl.java:805)

    at com.intellij.psi.impl.search.PsiSearchHelperImpl$26.compute(PsiSearchHelperImpl.java:1093)

I've updated the AndroidStudio, to latest one. But still the error occurs. Any fix or work around?

What did the documentation the error points to say about it? — G_V, Jan 28 '15 at 13:05
I am using android studio 1.3 stable version and still getting same errors as you are. I only tried to import my android project eclipse based. — Ahmed, Aug 06 '15 at 01:47

Happens because of the background indexing processes.

When the IDE is indexing, if we try to change the values in properties tab, then IndexNotReadyException is thrown.

Wait till indexing is complete.

Hope Google fixes this in AndroidStudio's next release!

This also happens in IntelliJ IDEA IDE too, which is JetBrains' product, so, I suppose, it's on JetBrains duty to deal with the bug. – Mike Jun 12 '15 at 16:11

File-> Invalidate Cache and Restart

This will stop the old indexing process and start a new one.

After that wait for indexing, and let that project build.

Unfortunately, the error persisted even after restart. – Chris - Jr Jul 18 '17 at 08:33

I faced the same problem and found solution according to this, I have changed the API level 22 to 21, problem solved.

API Level for XML layout was set **Automatically Pick Best ** which was API 22

enter image description here

And I change this API 22 to API 21:

and the exception removed.

Hope this help. Thanks

Links tend to change or go missing, could you explain some of the contents or quote it here? – abarisone Jun 17 '15 at 06:24
Doing this is the same as clicking the visual editor's "refresh" button. So unfortunately this isn't doesn't remedy the issue at hand :( – Jacksonkr Dec 09 '15 at 14:28
Well this happens on debug deploys of the APK, not in XML preview pane. – IgorGanapolsky Feb 03 '16 at 22:49

If you have tried opening the project built in esclipse from default Open Project option from Android Studio, try Importing the project and open it.

when that happend, run gradle method, then incremental builds are rebuild and indexing is restarted:

task _deleteIncrementals << {
    def dirName = new File("${rootDir}/$project.name/build/intermediates/builds/debug/")
    dirName.deleteDir()
}
