|  | # If you don't need to do a full clean build but would like to touch | 
|  | # a file or delete some intermediate files, add a clean step to the end | 
|  | # of the list.  These steps will only be run once, if they haven't been | 
|  | # run before. | 
|  | # | 
|  | # E.g.: | 
|  | #     $(call add-clean-step, touch -c external/sqlite/sqlite3.h) | 
|  | #     $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates) | 
|  | # | 
|  | # Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with | 
|  | # files that are missing or have been moved. | 
|  | # | 
|  | # Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory. | 
|  | # Use $(OUT_DIR) to refer to the "out" directory. | 
|  | # | 
|  | # If you need to re-do something that's already mentioned, just copy | 
|  | # the command and add it to the bottom of the list.  E.g., if a change | 
|  | # that you made last week required touching a file and a change you | 
|  | # made today requires touching the same file, just copy the old | 
|  | # touch step and add it to the end of the list. | 
|  | # | 
|  | # ************************************************ | 
|  | # NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST |

|  |  | 
|  | # For example: | 
|  | #$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates) | 
|  | #$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates) | 
|  | #$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -print0 | xargs -0 rm -f) | 
|  | #$(call add-clean-step, rm -rf $(PRODUCT_OUT)/data/*) | 
|  |  | 
|  | $(call add-clean-step, rm -rf $(PRODUCT_OUT)/system/app/ModuleMetadata) |
