Android Studio 4.0.1 released

Android Studio 4.0.1 was released, including fixes for the following public issues:

Android Gradle Plugin

  • Jacoco task reprocesses the same file too many times-incremental build
  • buildbuild-attributionandroidGradlePluginAttributionData: The process cannot access the file because the file is being used by another process
  • After generating the .apk, the versionName in the output.json file is wrong
  • Exception error message thrown from Jetifier

Dexer (D8)

  • One or more instructions prevented the use of the default interface method: java.util.function.Consumer it.unimi.dsi.fastutil.chars.CharConsumer.andThen(java.util.function.Consumer)
  • Desugaring: Static methods are not applicable to subclasses
  • Reverse porting makes D8 a generous line number and local variable table
  • Assertion errors on valid local information


  • When using "make project", AS reports build failure when using Kotlin DSL in buildSrc​​​​​​​​
