Adam Lesinski36c73a52016-08-11 13:39:24 -070012## Version 2.1
13### `aapt2 link ...`
14- Configuration Split APK support: supports splitting resources that match a set of
15 configurations to a separate APK which can be loaded alongside the base APK on
16 API 21+ devices. This is done using the flag
17 `--split path/to/split.apk:<config1>[,<config2>,...]`.
18- SDK version resource filtering: Resources with an SDK version qualifier that is unreachable
19 at runtime due to the minimum SDK level declared by the AndroidManifest.xml are stripped.

22### `aapt2 compile ...`
23- Pseudo-localization: generates pseudolocalized versions of default strings when the
24 `--pseudo-localize` option is specified.
25- Legacy mode: treats some class of errors as warnings in order to be more compatible
26 with AAPT when `--legacy` is specified.
27- Compile directory: treats the input file as a directory when `--dir` is
28 specified. This will emit a zip of compiled files, one for each file in the directory.
29 The directory must follow the Android resource directory structure
30 (res/values-[qualifiers]/file.ext).

32### `aapt2 link ...`
33- Automatic attribute versioning: adds version qualifiers to resources that use attributes
34 introduced in a later SDK level. This can be disabled with `--no-auto-version`.
35- Min SDK resource filtering: removes resources that can't possibly be selected at runtime due
36 to the application's minimum supported SDK level.
