#
# NOTE: IS_DESKTOP_ANDROID should be used sparingly.
#
# General Recommendation:
#   Avoid using this build time flag whenever possible. Rely on runtime
#   detection of features such as:
#     - Large screen availability
#     - Input modalities (e.g., touch, keyboard, mouse)
#     - Relevant Android system flags.
#
# DO:
#   - Use this flag ONLY for features with substantial binary size impact,
#     such as DevTools or Extensions, which contain significant code and
#     resource sizes.
#
# DON'T:
#   - Use this flag to enable feature flags or experiments.
#   - Use this flag in code shared with Android WebView.
#     Restrict its usage to the //chrome code directory whenever possible.
#
