Fix build failure when building unbundled apps

	// Don't run any hiddenapi rules if UNSAFE_DISABLE_HIDDENAPI_FLAGS=true. This is a performance

	// optimization that can be used to reduce the incremental build time but as its name suggests it

	// can be unsafe to use, e.g. when the changes affect anything that goes on the bootclasspath.

	if ctx.Config().IsEnvTrue("UNSAFE_DISABLE_HIDDENAPI_FLAGS") {

	// Instead create some rules to create fake hidden api files.

	config := ctx.Config()

	fakeHiddenApiRules := config.IsEnvTrue("UNSAFE_DISABLE_HIDDENAPI_FLAGS")

	// Don't run them in an unbundled build either because the chances are that the modules needed

	// are not available.

	fakeHiddenApiRules = fakeHiddenApiRules || config.UnbundledBuild()

	// Don't run them when always using prebuilts as they won't necessarily have the dex boot jars

	// available.

	if fakeHiddenApiRules {

		paths := android.OutputPaths{b.hiddenAPIFlagsCSV, b.hiddenAPIIndexCSV, b.hiddenAPIMetadataCSV}

		for _, path := range paths {

			ctx.Build(pctx, android.BuildParams{
