在Android源码环境下编译系统App使用第三方jar包的方法（备忘）

1 将要使用的jar包放入App的根目录， 即Android.mk所在目录

2 按如下方式编写Android.mk文件（########之间的行用于编译和使用jar包）

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

#LOCAL_JAVA_LIBRARIES := telephony-common

################################################
LOCAL_STATIC_JAVA_LIBRARIES := xutils
################################################

LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := AppStore

# Builds against the public SDK
#LOCAL_SDK_VERSION := current

LOCAL_CERTIFICATE := platform
LOCAL_PRIVILEGED_MODULE := true

LOCAL_PROGUARD_FLAG_FILES := proguard.flags

include $(BUILD_PACKAGE)

##################################################
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := xutils:xUtils-2.6.11.jar
include $(BUILD_MULTI_PREBUILT)

# This finds and builds the test apk as well, so a single make does both.
include $(call all-makefiles-under,$(LOCAL_PATH))
