Note: The Android layoutopt tool has been replaced by the lint tool beginning in SDK Tools revision 16. The lint tool reports UI layout performance issues in a similar way as layoutopt, and detects additional problems.

For more information about using lint, see Improving Your Code with lint.

layoutopt is a command-line tool that helps you optimize the layouts and layout hierarchies of your applications.

This document is a reference to the available command line options. For more information and sample output of the tool, see Optimizing layouts with layoutopt.
