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。

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 (系统限制的权限)
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)
# 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、装载需要.so(动态库)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、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。
在Android源码开发过程中,需要整合进第三方APP到系统中,作为内置应用。如果是第三方APP是以APK形式整合进项目中,那么根据平台和公司的要求,只需修改编译脚本就可以实现整合,这里不再赘述;本文讲解拿到的第三方app是源码,需要自己写android.mk文件实现编译apk功能。
现在Android app ide主要是两个工具eclipse和android studio。Eclipse已经从google的android开发者网站中移除了下载链接,现在主流的android app开发工具就是Android studio。
android 源码中package/app目录下的应用大部分还是eclipse的代码结构,第三方app如果是eclipse编写的,那么去源码中package/app目录下找一个应用的android.mk 类比改一下就可以。这里主要讲一下android studio 项目的android.mk怎么写。
android studio编写的app,app源码代码结构就跟eclipse不一样,实际上有用的app目录下的内容。我的android.mk就放在app/src/main目录下(一般android.mk都放在应用目录下,但实际上android源码在编译时会遍历package/app目录下的android.mk文件,不放心可以在项目应用根目录下写android.mk)
首先查看app/src/main目录下的build.gradle文件,在这个文件中会写明在开发中引用了哪些包,如果不是android源码中带有的(如android-support-v4,android-support-v7-xxx等),那么要去android studio的安装目录下找到这些jar包,放到app/src/main/libs/目录下(没有就自己创建一个),因为android studio在使用时会自动下载需要的包到安装目录下,所以在拿到源码时实际上这些包是没有的,在本地用android studio导入项目,它会自动联网同步这些包。
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS) (经典开头两句)
LOCAL_PACKAGE_NAME := xxx(apk的名字,如果这个值写的是Test,那么编译出来的就是Test.apk)
LOCAL_CERTIFICATE := platform (系统签名)
LOCAL_RESOURCE_DIR += $(LOCAL_PATH)/res
src_dirs := java/
LOCAL_SRC_FILES := $(call all-java-files-under, $(src_dirs))
##声明使用的java文件和资源文件地址,如果使用到aidl,需要特别声明,常见写法如下
#LOCAL_SRC_FILES += \
# src/xx/xx/xx/aidl/XxxOne.aidl \
# src/xx/xx/xx//aidl/XxxTwo.aidl
LOCAL_MULTILIB := 32(添加这句是为了防止在编译后使用apk时,提示so是32位而不是64位导致应用fc)
LOCAL_PREBUILT_JNI_LIBS_x86 := jniLibs/x86/libxxx.so
LOCAL_PROGUARD_ENABLED := disabled (添加这句是为了防止在编译后使用apk时,提示找不到so库中对应的方法导致fc)
#如果使用了jni就要这么写
LOCAL_STATIC_JAVA_LIBRARIES += design \
android-support-v4 \
android-support-v7-appcompat \
android-support-v7-recyclerview \
recyclerview-v7 \
itextpdf(第三方包名)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES += \
itextpdf:libs/itextpdf-5.5.9.jar
#第三方包需要通过LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES声明
LOCAL_PROGUARD_FLAG_FILES := proguard.flags
##在编译时如果提示包中有warning时,需要按照要求在文件中写dontwarn,proguard.flags需要自行创建,android studio不会创建这个文件
下面是我写的android.mk,以供参考:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_PACKAGE_NAME := 应用名
LOCAL_CERTIFICATE := platform
#如果使用的系统的包,需要引入他们使用的资源文件,否则会提示编译资源找不到的错误
LOCAL_RESOURCE_DIR += frameworks/support/v7/appcompat/res
LOCAL_RESOURCE_DIR += frameworks/support/v7/gridlayout/res
LOCAL_RESOURCE_DIR += frameworks/support/v7/recyclerview/res
LOCAL_RESOURCE_DIR += frameworks/support/design/res
LOCAL_RESOURCE_DIR += $(LOCAL_PATH)/res
src_dirs := java/
LOCAL_SRC_FILES := $(call all-java-files-under, $(src_dirs))
#LOCAL_SRC_FILES += \
# src/xx/xx/xx/XxxOne.aidl \
# src/xx/xx/xx/XxxTwo.aidl
LOCAL_STATIC_JAVA_LIBRARIES += design \
android-support-v4 \
itextpdf \
android-support-v7-appcompat \
android-support-v7-recyclerview \
recyclerview-v7
LOCAL_PREBUILT_JNI_LIBS := jniLibs/xx/libxxx.so
LOCAL_MULTILIB := 32
LOCAL_PROGUARD_FLAG_FILES := proguard.flags
LOCAL_AAPT_FLAGS := --auto-add-overlay
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.appcompat
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.gridlayout
LOCAL_AAPT_FLAGS += --extra-packages com.android.datetimepicker
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.recyclerview
LOCAL_AAPT_FLAGS += --extra-packages android.support.design
LOCAL_PROGUARD_ENABLED := disabled
include $(BUILD_PACKAGE)
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES += \
itextpdf:libs/itextpdf-5.5.9.jar
include $(BUILD_MULTI_PREBUILT)
include $(call all-makefiles-under,$(LOCAL_PATH))
特别补充:
1.第三方APP如果使用到了design-xx.jar包中的类,编译可以通过,但是在使用时APP会出现crash问题,log反应是design中类找不到。design是android提供的jar包,出现这个问题是,要去framework/support/design/目录下执行mm编译出design对应的jar包,再编译app,这时编译出的apk就没有找不到类的异常了
2.可以把android.mk放到应用的跟根目录下,这时候需要修改java文件,资源文件,包的引用目录地址
