Android.mk各种文件编译汇总

一、源代码编译

1.1 so预编译

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libAppArea
LOCAL_SRC_FILES :=libAppArea.so
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_MODULE_SUFFIX:=$(HOST_JNILIB_SUFFIX)
LOCAL_CERTIFICATE:=platform
LOCAL_PRELINK_MODULE := false
include $(BUILD_PREBUILT)

1.2 share lib编译

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
#LDFLAGS	+=	-ldl
LOCAL_LDLIBS    := -ldl -lm -llog -llibc
LOCAL_MODULE    := libnandFlashReadPage_jni
LOCAL_SRC_FILES := nandFlashReadPage_jni.cpp\

LOCAL_SHARED_LIBRARIES := libdl\
liblog\
libpre_NandRecognition\
libpre_AppArea\
libc\
libstdc++

LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)

升级到Android 4.0。 原来我们在3.2 版本号以下编译的程序有些不能编译通过。

特别是

复制apk,复制动态库的Android.mk 文件，经过研究。现解决方法例如以下。

错误信息：The following variables have been changed: PRODUCT_COPY_FILES. Stop.

解决的方法：以下几个样例共參考。各自是复制APK；SO；ZIP; db; jpg

假设有其它更好的办法。

请留言。

include $(BUILD_PREBUILT)

注意：LOCAL_PATH:= $(call my-dir) 这个变量，在一个Android.MK文件里仅仅能有一个。

多个LOCAL_PATH会出现错误。

而include $(CLEAR_VARS)

和include $(BUILD_PREBUILT)

能够是多个。

在Android开发的时候。常常会使用到用c或c++编写的第三方的静态库。

假设有源代码的话，能够直接跟你自己的代码一去编译成动态库so。可是假设没有源代码的话，你就必须在自己的动态库so里面将别人生成好的静态库导入进来一起编译了。

我在编译的时候遇到了不少问题。我认为有必要进行总结一下。

以下我以一个简单的实际样例来解说怎样在动态库中导入静态库。

静态库中的源码有两个文件：static.h, static.c，有一个add方法

static.h
#include <stdio.h>
int add(int x, int y);
static.c
#include "static.h"
int add(int x, int y)
{
return x + y;
}

将它编译成静态库。Android.mk例如以下：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := static_add
LOCAL_SRC_FILES := static.c
include $(BUILD_STATIC_LIBRARY)

注意编译静态库的时候，必须有一个Application.mk文件：

APP_MODULES:=static_add

APP_MODULES的值应该和Android.mk中的LOCAL_MODULE的值保持一样。

然后调用ndk-build进行编译生成libstatic_add.a静态库。

hejinlai_iMac:jni hejinlai$ ndk-build

Prebuilt : libstatic_add.a <= jni/

生成静态库后，然后编写动态库中的源码: share.h share.c

share.h
#include <stdio.h>
int test_add(int x, int y);
share.c
1234567 #include "share.h"
#include "static.h"
int test_add(int x, int y)
{
// 调用static里面的方法
return add(x, y);
}

编写导入静态库的Android.mk：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := static_add
LOCAL_SRC_FILES := libstatic_add.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE    := share_add
LOCAL_STATIC_LIBRARIES := static_add
LOCAL_SRC_FILES := share.c
include $(BUILD_SHARED_LIBRARY)

注意上面生成的libstatic_add.a必须跟Android.mk放在同一文件夹下，否则须要填写对应的路径，然后进行编译：

hejinlai_iMac:jni hejinlai$ ndk-build

Compile thumb : share_add <= share.c

Prebuilt : libstatic_add.a <= jni/

SharedLibrary : libshare_add.so

Install : libshare_add.so => libs/armeabi/libshare_add.so

提示so编译成功。

须要注意的是我这边share.c和static.c放在同一文件夹下，假设放在不同的文件夹下，须要指定

LOCAL_C_INCLUDES链接到对应的路径。

一、Eclipse中集成第三方jar包及.so动态库

MyMapsproject下创建文件夹libs以及libs/armeabi，把baidumapapi.jar放在的libs/文件夹下，把libBMapApiEngine_v1_3_1.so放在libs/armeabi/下。

Eclipse中把第三方jar包baidumapapi.jar打包到MyMaps的步骤：

1. 右击project。选择Properties；

2. Java Build Path，选择Libraries。

3. Libraries页面点击右面button“Add Library…”；

4. 选择“User Library”，点击“Next”；

5. 点击“User Libraries”button；

6. 在弹出界面中，点击“New…”；

7. 输入“User library name”。点击“OK”确认；

8. 返回之后。选择刚刚创建的User library，右面点击“AddJARs”；

9. 选择MyMaps/libs/下的baidumapapi.jar。

10. 确认，返回。

这样。编译之后。该jar包就会被打进MyMaps.apk中，libBMapApiEngine_v1_3_1.so也被打包在lib/armeabi/中。

程序执行过程中，libBMapApiEngine_v1_3_1.so被放在/data/data/<yourAppPackage>/lib/下，载入动态库时系统会从程序的该lib/文件夹下查找.so库。

二、源代码中集成第三方集成jar包及.so动态库

Android源代码中MyMaps放在packages/apps下。MyMaps下创建文件夹libs以及libs/armeabi。并把baidumapapi.jar放在libs/，把libBMapApiEngine_v1_3_1.so放在libs/armeabi。

2.1 改动Android.mk文件

Android.mk文件例如以下：

[plain] view
plaincopy

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_STATIC_JAVA_LIBRARIES := libbaidumapapi

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := MyMaps

include $(BUILD_PACKAGE)

##################################################

include $(CLEAR_VARS)

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES :=libbaidumapapi:libs/baidumapapi.jar

LOCAL_PREBUILT_LIBS :=libBMapApiEngine_v1_3_1:libs/armeabi/libBMapApiEngine_v1_3_1.so

LOCAL_MODULE_TAGS := optional

include $(BUILD_MULTI_PREBUILT)

# Use the following include to make our testapk.

include $(callall-makefiles-under,$(LOCAL_PATH))

1 集成jar包

LOCAL_STATIC_JAVA_LIBRARIES取jar库的别名。能够随意取值；

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES指定prebuiltjar库的规则，格式：别名:jar文件路径。

注意：别名一定要与LOCAL_STATIC_JAVA_LIBRARIES里所取的别名一致。且不含.jar；jar文件路径一定要是真实的存放第三方jar包的路径。

编译用BUILD_MULTI_PREBUILT。

2 集成.so动态库

LOCAL_PREBUILT_LIBS指定prebuilt so的规则，格式：别名:so文件路径。

注意：别名一般不可改变，特别是第三方jar包使用.so库的情况，且不含.so；so文件路径一定要是真实的存放第三方so文件的路径。

编译拷贝用BUILD_MULTI_PREBUILT。

2.2 增加到GRANDFATHERED_USER_MODULES

在文件user_tags.mk中，把libBMapApiEngine_v1_3_1增加到GRANDFATHERED_USER_MODULES中

[plain] view
plaincopy

GRANDFATHERED_USER_MODULES += \

… \

libBMapApiEngine_v1_3_1

user_tags.mk能够是build/core下的。也能够是$(TARGET_DEVICE_DIR)下的。推荐改动$(TARGET_DEVICE_DIR)下的。

2.3 编译结果

MyMaps.apk编译生成在out/target/product/<YourProduct>/system/app/下；

libBMapApiEngine_v1_3_1.so放在out/target/product/<YourProduct>/system/lib/下。这也是系统载入动态库时搜索的路径。

2.4 源代码中预编译静态库

測试通过

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := libKL15APIA
#LOCAL_SRC_FILES := libKL15APIA.a
LOCAL_PREBUILT_LIBS := libKL15APIA.a
LOCAL_MODULE_TAGS := optional
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)
LOCAL_CERTIFICATE:=platform
include $(BUILD_MULTI_PREBUILT)
