Android support in Bazel

Disclaimer

NOTE: This branch contains a development preview of the Starlark implementation of Android rules for Bazel. This code is incomplete and may not function as-is.

A version of Bazel built at or near head or a recent pre-release and the following flags are necessary to use these rules:

--experimental_enable_android_migration_apis
--experimental_google_legacy_api
--incompatible_java_common_parameters
--android_databinding_use_v3_4_args
--experimental_android_databinding_v2

Overview

This repository contains the Starlark implementation of Android rules in Bazel.

The rules are being incrementally converted from their native implementations in the Bazel source tree.

For the list of Android rules, see the Bazel documentation.

Getting Started

To use the Starlark Bazel Android rules, add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

# Or a later commit
RULES_ANDROID_COMMIT= "0bf3093bd011acd35de3c479c8990dd630d552aa"
RULES_ANDROID_SHA = "b75a673a66c157138ab53f4d8612a6e655d38b69bb14207c1a6675f0e10afa61"
http_archive(
    name = "build_bazel_rules_android",
    url = "https://github.com/bazelbuild/rules_android/archive/%s.zip" % RULES_ANDROID_COMMIT,
    sha256 = RULES_ANDROID_SHA,
    strip_prefix = "rules_android-%s" % RULES_ANDROID_COMMIT,
)
load("@build_bazel_rules_android//:prereqs.bzl", "rules_android_prereqs")
rules_android_prereqs()
load("@build_bazel_rules_android//:defs.bzl", "rules_android_workspace")
rules_android_workspace()

register_toolchains(
"@build_bazel_rules_android//toolchains/android:android_default_toolchain",
"@build_bazel_rules_android//toolchains/android_sdk:android_sdk_tools",
)

Then, in your BUILD files, import and use the rules:

load("@build_bazel_rules_android//rules:rules.bzl", "android_binary", "android_library")
android_binary(
    ...
)

android_library(
    ...
)
