A. android 项目如何导出带源码的jar包

用rar压缩软件都可以打开的

B. android怎么在源码导入jar包

在Android源码编译成功的基础上重新编译带自己API的android.jar需要进行以下几步操作：

1、添加自己源代码，在Android源码frameworks/base目录下新建一个文件夹保存代码，如tv，以包的形式命名添加的文件所在的路径，如/tv/java/android/tv，添加的java文件开头定义的包即是编译成功的class文件所在的包。
2、修改makefile文件
2.1 修改build/core/pathmap.mk文件
在FRAMEWORKS_ BASE_ SUBDIRS变量后添加tv\，代码如下（makefile文件中的语句以Tab键空格开头）
FRAMEWORKS_BASE_SUBDIRS := \ $(addsuffix /java, \ core \ graphics \ location \ media \ opengl \ sax \ telephony \ wifi \ vpn \ keystore \ tv \ )
2.2 修改frameworks/base/Android.mk 文件
在packages_to_ document变量后添加自己源代码的包名称，如android/tv，结果如下（makefile文件中的语句以Tab键空格开头）
packages_to_document := \
android \
javax/microedition/khronos android/tv 3 在ubuntu命令行终端使用如下命令进行编译：
make clean
make update-api
make PRODUCT-sdk-sdk
最后一行也可以用如下两个命令代替： make –j4 make sdk 4 编译结果
4.1 android.jar文件所在的目录为
/out/target/common/obj/PACKAGING/android_jar_intermediates/android.jar并在/out/target/common/obj/JAVA_LIBRARIES/android_stubs_current_interme diates/src目录下重新以package形式组织所有生成到android.jar中的源代码。 4.2 SDK所在目录为
out/host/linux-x86/sdk/，生成的sdk文件目录和压缩包为： android-sdk_eng.xxx_linux-x86
android-sdk_eng.xxx_linux-x86.zip(xxx为自己android源码所在的文件名)

C. 求解答，Android源码编译时怎的添加第三方jar包

Android.mk添加第三方jar包

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_STATIC_JAVA_LIBRARIES := xsocket jackson-mapper logging jackson-core javatar log4j
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-subdir-java-files)
LOCAL_PACKAGE_NAME := test

LOCAL_CERTIFICATE := platform
include $(BUILD_PACKAGE)
##################################################
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := xsocket:lib/xSocket-2.8.14.jar \
jackson-mapper:lib/jackson-mapper-asl-1.6.2.jar \
logging:lib/commons-logging.jar \
jackson-core:lib/jackson-core-asl-1.6.2.jar \
javatar:lib/javatar-2.5.jar \
log4j:lib/log4j-1.2.15.jar
include $(BUILD_MULTI_PREBUILT)
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

以上是我的一个项目中所需要的第三方jar包，主要参考了Android源码中的Calculator应用，该应用也引用了一个第三方的jar包arity-2.1.2.jar。
需要注意的是，当你要引用的jar包不止一个时，有两个关键的地方需要注意的。
LOCAL_STATIC_JAVA_LIBRARIES := xsocket jackson-mapper logging jackson-core javatar log4j
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := xsocket:lib/xSocket-2.8.14.jar \
jackson-mapper:lib/jackson-mapper-asl-1.6.2.jar \
logging:lib/commons-logging.jar \
jackson-core:lib/jackson-core-asl-1.6.2.jar \
javatar:lib/javatar-2.5.jar \
log4j:lib/log4j-1.2.15.jar
xsocket jackson-mapper logging jackson-core javatar log4j这几个只是名字，可以随便取。LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES后面才是真正其作用的地方。如：
xsocket:lib/xSocket-2.8.14.jar 引用的是lib目录中的xSocket-2.8.14.jar。
还要注意的是 := 不要写成了+=了哦。

附：编写各种类型的Android.mk，出处我忘记了，是以前浏览是拷贝下来的。
一、编译一个简单的APK
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Build all java files in the java subdirectory
LOCAL_SRC_FILES := $(call all-subdir-java-files)
# Name of the APK to build
LOCAL_PACKAGE_NAME := LocalPackage
# Tell it to build an APK
include $(BUILD_PACKAGE)
二、编译一个依赖静态.jar文件的APK
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# List of static libraries to include in the package
LOCAL_STATIC_JAVA_LIBRARIES := static-library
# Build all java files in the java subdirectory
LOCAL_SRC_FILES := $(call all-subdir-java-files)
# Name of the APK to build
LOCAL_PACKAGE_NAME := LocalPackage
# Tell it to build an APK
include $(BUILD_PACKAGE)
注：LOCAL_STATIC_JAVA_LIBRARIES 后面应是你的APK程序所需要的JAVA库的JAR文件名。
三、编译一个需要platform key签名的APK
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Build all java files in the java subdirectory
LOCAL_SRC_FILES := $(call all-subdir-java-files)
# Name of the APK to build
LOCAL_PACKAGE_NAME := LocalPackage
LOCAL_CERTIFICATE := platform
# Tell it to build an APK
include $(BUILD_PACKAGE)
注：LOCAL_CERTIFICATE 后面应该是签名文件的文件名
四、编译一个需要特殊vendor key签名的APK
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Build all java files in the java subdirectory
LOCAL_SRC_FILES := $(call all-subdir-java-files)
# Name of the APK to build
LOCAL_PACKAGE_NAME := LocalPackage
LOCAL_CERTIFICATE := vendor/example/certs/app
# Tell it to build an APK
include $(BUILD_PACKAGE)
五、装载一个普通的第三方APK
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Mole name should match apk name to be installed.
LOCAL_MODULE := LocalMoleName
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := platform
include $(BUILD_PREBUILT)
六、装载需要.so（动态库）的第三方apk
LOCAL_PATH := $(my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := input_android_v1.1_1000e
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := platform
include $(BUILD_PREBUILT)
#################################################################
####### the library to /system/lib #########################
#################################################################
include $(CLEAR_VARS)
LOCAL_MODULE := libinputcore.so
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)
LOCAL_SRC_FILES := lib/$(LOCAL_MODULE)
OVERRIDE_BUILD_MODULE_PATH := $(TARGET_OUT_INTERMEDIATE_LIBRARIES)
include $(BUILD_PREBUILT)
七、编译一个静态java库
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Build all java files in the java subdirectory
LOCAL_SRC_FILES := $(call all-subdir-java-files)
# Any libraries that this library depends on
LOCAL_JAVA_LIBRARIES := android.test.runner
# The name of the jar file to create
LOCAL_MODULE := sample
# Build a static jar file.
include $(BUILD_STATIC_JAVA_LIBRARY)
注：LOCAL_JAVA_LIBRARIES表示生成的java库的jar文件名。
