Error:Internal error: (java.lang.ClassNotFoundException) com.google.wireless.android.sdk.stats.IntellijIndexingStats$Index

Question

Android Studio 3.4.

Project SDK (Android API 19 Platform).

Not using FindBugs or SpotBugs.

Every attempt to build, I get this error:

Answer 1

Solved for me, finally, after months. Note that I have never used FindBugs or SpotBugs, although most posts related to this error mention it.

The solution is to change the compiler from javac to Eclipse. I followed the picture here (don't worry if you don't read Chinese; you won't need to; the picture just makes it clear how to change the compiler).

I have no idea why this works and would highly appreciate informed commentary.

Answer 2

I am facing the same issue with android studio 3.4 and 3.4.1 as well but this work fine with android studio 2.3.3 and 3.0 as well.

Answer 3

Bug seems to be in Android Studio 3.4.x so I downloaded beta version of Android Studio 3.5 and error is gone.

You can download preview version from here :
