    idl_parcelables = ["MyParcelable.aidl"] # bazel.helloandroid.MyParcelable

    # We don't need to specify idl_import_root since the aidl file
    # which declares bazel.helloandroid.MyParcelable
    # is present at java/bazel/helloandroid/MyParcelable.aidl
    # underneath a java root (java/).

    ],

    # We need to specify idl_import_root because the aidl file which
    # declares android.helloandroid.OtherParcelable is not positioned
    # at android/helloandroid/OtherParcelable.aidl under a normal java root.
    # Setting idl_import_root to "src" in //java/bazel/helloandroid
    # adds java/bazel/helloandroid/src to the list of roots
    # the aidl compiler will search for imported types.
    idl_import_root = "src",
