I've recently updated Android Studio and my build.gradle version to 3.2.0-beta01.
When I build and run the project !zip.isFile() error occurs with information below:
Caused by: java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: !zip.isFile()
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformDexWithInstantRunSlicesApkForDebug'.
The error vanished, after disabling Instant Run.
Android Studio -> Preferences -> Instant Run
Google has indicated that they are going to fix it in Beta-02
