Lawnchair 12.1

Lawnchair is a free, open-source home app for Android. Taking Launcher3—Android’s default home app—as a starting point, it ports Pixel Launcher features and introduces rich options for customization. This branch houses the codebase of Lawnchair 12.1, currently in alpha and based on Launcher3 from Android 12.1. For Lawnchair 9, 10, 11, and 12, see the branches with the 9-, 10-, 11-, and 12- prefixes, respectively.

Contribute code

Whether you’ve fixed a bug or introduced a new feature, we welcome pull requests! (If you’d like to make a larger change and check with us first, you can do so via Lawnchair’s Telegram group chat.) To help translate Lawnchair 12.1 instead, please see “Translate.”

You can use Git to clone this repository:

git clone --recursive https://github.com/LawnchairLauncher/lawnchair.git

To build the app, select the lawnWithQuickstepDebug build type. Should you face errors relating to the iconloaderlib and searchuilib projects, run git submodule update --init --recursive.

Here are a few contribution tips:

• The lawnchair package houses Lawnchair’s own code, whereas the src package includes a clone of the Launcher3 codebase with modifications. Generally, place new files in the former, keeping changes to the latter to a minimum.

• You can use either Java or, preferably, Kotlin.

• Make sure your code is logical and well formatted. If using Kotlin, see “Coding conventions” in the Kotlin documentation.

• Set 12.1-dev as the base branch for pull requests.

• When using quotation marks, insert the symbols specific to the target language, as listed in this table.

• Lawnchair uses title case for some English UI text. Title case isn’t used in other languages; opt for sentence case instead.

• Some English terminology may have no commonly used equivalents in other languages. In such cases, use short descriptive phrases—for example, the equivalent of bottom row for dock.
