Note: The Android layoutopt tool has been replaced by the lint tool beginning in ADT and SDK Tools revision 16.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 and the lint reference documentation.
