Multiple entries with same key: 24.0.0 rc4=24.0.0 rc4
问题 After upgrade Android Studio to 2.2.3 it shows an error with: IllegalArgumentException: Multiple entries with same key: 24.0.0 rc4=24.0.0 rc4 and 24.0.0 rc4=24.0.0 rc4 回答1: Had this occur recently after updating a few bits. My solution was to open the Preferences in Android Studio, browse to Android SDK -> SDK Tools , you will most likely see multiple copies of 24.0.0 rc4 (one with a dash instead of a space in the version name) under Android SDK Build-Tools . Uninstall both copies by
