關於在android源碼編譯時引用第三方jar寶--需要在android.mk中配置

今天進行android源碼編譯時出現一個問題，報錯找不到文件，最後查看到那些找不到的問題全部都是第三方jar包裏的引用文件，於是百度找解決辦法。終於找到解決辦法，現在分享給大家，我已經親測通過了。

轉自：https://www.cnblogs.com/hopetribe/archive/2012/04/23/2467060.html

開始正文：

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))

以上是我的一個項目中所需要的第三方jar包，主要參考了Android源碼中的Calculator應用，該應用也引用了一個第三方的jar包arity-2.1.2.jar。

需要注意的是，當你要引用的jar包不止一個時，有兩個關鍵的地方需要注意的。

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這幾個隻是名字，可以隨便取。LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES後麵才是真正其作用的地方。如：

xsocket:lib/xSocket-2.8.14.jar 引用的是lib目錄中的xSocket-2.8.14.jar。

還要注意的是 := 不要寫成了+=了哦。

下麵附上：編寫各種類型的Android.mk

一、編譯一個簡單的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、編譯一個依賴靜態.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 後麵應是你的APK程序所需要的JAVA庫的JAR文件名。

三、編譯一個需要platform key簽名的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 後麵應該是簽名文件的文件名

四、編譯一個需要特殊vendor key簽名的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、裝載一個普通的第三方APK

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Module name should match apk name to be installed.
LOCAL_MODULE := LocalModuleName
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := platform
include $(BUILD_PREBUILT) 

六、裝載需要.so（動態庫）的第三方apk

 LOCAL_PATH := $(my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := baiduinput_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)

#################################################################
####### copy 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、編譯一個靜態java庫

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庫的jar文件名。
