1. 第一次全编译project(随机eng/user),然后保存,以取代java代码jar包,在alps/out/target/common/obj/JAVA_LIBRARIES/xxx__intermediates夹 classes.jar javalib.jar 2. 请将以下文件保存成java_library_prebuilt.mk,并放在alps/build/core/文件夹以下: 注意:有11处须要tab键开头(make语法对命令须要tab键开头,但站点不支持tab键),请保存成文件后打开编辑,将11处(下面有标志)又一次用tab键处理一遍。 ## LOCAL_SRC_FILES := ifdef LOCAL_IS_HOST_MODULE $(error $(LOCAL_PATH): Just for target java library) endif LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX) LOCAL_MODULE_CLASS := JAVA_LIBRARIES LOCAL_BUILT_MODULE_STEM := javalib.jar intermediates.COMMON := $(call local-intermediates-dir,COMMON) full_classes_jar := $(intermediates.COMMON)/classes.jar common_javalib.jar := $(intermediates.COMMON)/$(LOCAL_BUILT_MODULE_STEM) LOCAL_INTERMEDIATE_TARGETS += $(full_classes_jar) $(common_javalib.jar) ifneq (true,$(WITH_DEXPREOPT)) LOCAL_DEX_PREOPT := else ifeq (,$(TARGET_BUILD_APPS)) ifndef LOCAL_DEX_PREOPT LOCAL_DEX_PREOPT := true endif endif endif ifeq (false,$(LOCAL_DEX_PREOPT)) LOCAL_DEX_PREOPT := endif include $(BUILD_SYSTEM)/base_rules.mk $(cleantarget): PRIVATE_CLEAN_FILES += $(intermediates.COMMON) $(full_classes_jar) : $(LOCAL_PATH)/classes.jar | $(ACP) $(call copy-file-to-target) #注意:这里必须以tab键开头 $(common_javalib.jar) : $(LOCAL_PATH)/$(LOCAL_BUILT_MODULE_STEM) | $(full_classes_jar) $(ACP) $(call copy-file-to-target) #注意:这里必须以tab键开头 ifdef LOCAL_DEX_PREOPT dexpreopt_boot_jar_module := $(filter $(LOCAL_MODULE),$(DEXPREOPT_BOOT_JARS_MODULES)) ifneq ($(dexpreopt_boot_jar_module),) dexpreopted_boot_jar := $(DEXPREOPT_BOOT_JAR_DIR_FULL_PATH)/$(dexpreopt_boot_jar_module)_nodex.jar $(LOCAL_BUILT_MODULE) : $(dexpreopted_boot_jar) | $(ACP) $(call copy-file-to-target) #注意:这里必须以tab键开头 dexpreopted_boot_odex := $(DEXPREOPT_BOOT_JAR_DIR_FULL_PATH)/$(dexpreopt_boot_jar_module).odex built_odex := $(basename $(LOCAL_BUILT_MODULE)).odex $(built_odex) : $(dexpreopted_boot_odex) | $(ACP) $(call copy-file-to-target) #注意:这里必须以tab键开头 else built_odex := $(basename $(LOCAL_BUILT_MODULE)).odex $(built_odex): PRIVATE_MODULE := $(LOCAL_MODULE) $(built_odex) : $(DEXPREOPT_BOOT_ODEXS) $(built_odex) : $(common_javalib.jar) | $(DEXPREOPT) $(DEXOPT) @echo "Dexpreopt Jar: $(PRIVATE_MODULE) ($@)" #注意:这里必须以tab键开头 $(hide) rm -f $@ #注意:这里必须以tab键开头 @mkdir -p $(dir $@) #注意:这里必须以tab键开头 $(call dexpreopt-one-file,$<,$@) #注意:这里必须以tab键开头 $(LOCAL_BUILT_MODULE) : $(common_javalib.jar) | $(ACP) $(AAPT) $(call copy-file-to-target) #注意:这里必须以tab键开头 ifneq (nostripping,$(LOCAL_DEX_PREOPT)) $(call dexpreopt-remove-classes.dex,$@) #注意:这里必须以tab键开头 endif endif else $(LOCAL_BUILT_MODULE) : $(common_javalib.jar) | $(ACP) $(call copy-file-to-target) #注意:这里必须以tab键开头 endif 3. 在alps/build/core/config.mk里加入: BUILD_JAVA_LIBRARY_PREBUILT:= $(BUILD_SYSTEM)/java_library_prebuilt.mk 4. 删除相应的java代码及相应的Android.mk,然后在当前文件夹创建新的Android.mk。并复制第1步备份的2仅仅文件到Android.mk旁边(注意。文件名称不能改动,否则无法识别!!!),新的Android.mk编写例如以下: LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := services LOCAL_MODULE_PATH := $(TARGET_OUT_JAVA_LIBRARIES) include $(BUILD_JAVA_LIBRARY_PREBUILT) 5. 又一次完整的编译project(随意eng/user),下载查看效果 6. 重要提示,因为第1步保存的classes.jar是没有经过proguard。流出去非常easy被反编译,请做自己proguard,但请不要把接口proguard,否则编译失败!
