# Android Asset Packaging Tool 2.0 (AAPT2) release notes

## Version 2.0

### `aapt2 compile ...`

- Pseudo-localization: generates pseudolocalized versions of default strings when the

  `--pseudo-localize` option is specified.

- Legacy mode: treats some class of errors as warnings in order to be more compatible

  with AAPT when `--legacy` is specified.

- Compile directory: treats the input file as a directory when `--dir` is

  specified. This will emit a zip of compiled files, one for each file in the directory.

  The directory must follow the Android resource directory structure

  (res/values-[qualifiers]/file.ext).

### `aapt2 link ...`

- Automatic attribute versioning: adds version qualifiers to resources that use attributes

  introduced in a later SDK level. This can be disabled with `--no-auto-version`.

- Min SDK resource filtering: removes resources that can't possibly be selected at runtime due

  to the application's minimum supported SDK level.
