# There are two ways to provide Android SDK and NDK locations to a Bazel build:
# 1. Using standard environment variables (ANDROID_HOME and ANDROID_NDK_HOME)
# 2. Using the 'android_sdk_repository_extension.configure' API in the
# MODULE.bazel file
#
# The second option overrides the environment variables that are usually
# already set on the developer's machine.
# This leads to a situation where the `adb` tool used to push Android tests to
# the local device or emulator during the build differs from the version already
# running (e.g., used by the Android Studio Logcat viewer).
# When this happens, the ADB daemon restarts, leading to slower test execution
# and sometimes obscure test errors.
# To overcome this, we enforce the use of environment variables
# only when using this 'tools/bazel' script, which allows developers to use a
# local version of Bazel together with the local version of the SDK and NDK.
# We explicitly specify the required Android SDK version in MODULE.bazel, which
# ensures that if the local SDK is used, it is the correct version.
