Fatal Error: Invalid Layout of java.lang.String at value

In case of an Android project, you have to remove Android Lib from the launch configuration for that specific class. Use the “walkthrough” below as a guide.

  • Project->Properties->Run/Debug Settings;
  • Select your Class and click “Edit“;
  • Open the tab “Classpath” and remove Android Lib from “Bootstrap Entries“;
  • Apply everything and Run the class again.
