在源代码中（通过Android.mk）编译项目时，如何将*.so库编译进apk包

[jlense]

用Eclipse编译工程，若工程下有libs目录，会自动将里面的*.so库编译到apk包中。我现在需要用到*.so库和Android.mk文件编译工程，但用Eclipse编译时，Android.mk不起作用。

Android.mk好像只有在通过源代码编译工程时才起作用（我目前只发现这个办法），即在Linux环境下的Android源代码目录中，通过make或mmm命令编译。但通过mmm编译的工程，不会把工程下libs目前中的*.so库添加进apk包里，是不是要在Android.mk文件中添加一些申明什么的？

还有，想知道Android源代码中，重启手机的相关代码在哪个部分。

有了解的朋友请支个招啊！谢谢！

上面的3都是在frame/base目录下

好像2有点老了，我记得google 的 platform maillist上面有个人发了个文档是讲加入自己的库的例子的，你可以搜搜看

2楼的回贴被验证了吗？呵呵

[kofihust]

给你看个我写的调用静态库和动态库的例子，是可以把所需要的库打进apk里的，以下为Android.mk中的一段
LOCAL_SHARED_LIBRARIES := \
libandroid_runtime \
libnativehelper \
libcutils \
libutils

LOCAL_STATIC_LIBRARIES := \
libfreetype \
libt1

# Also need the JNI headers.
LOCAL_C_INCLUDES += \
$(JNI_H_INCLUDE) \
$(LOCAL_PATH)/include

LOCAL_CFLAGS += -O2

LOCAL_CFLAGS += -DHAVE_CONFIG_H

LOCAL_LDLIBS += -lpthread


LOCAL_PRELINK_MODULE := false

include $(BUILD_SHARED_LIBRARY)

[yili_xie]

上面这个.mk是NDK自己生成的还是楼上的写的啊？

想知道这个.mk是NDK生成的还是楼上的自己写的啊，请教下这个.mk和apk在source中的目录结构是啥样的呢，谢谢拉

[yili_xie]

楼主把NDK里面的doc目录下的overview仔细看一下就非常清楚如何在APK中加.so了，截取一段给你看看：
III. NDK development in practice:
---------------------------------

Here's a very rough overview of how you can develop native code with the
Android NDK:

1/ Run build/host-setup.sh to configure the NDK

2/ Place your native sources under $PROJECT/jni/...

3/ Write $PROJECT/jni/Android.mk to describe your sources
to the NDK build system

4/ Write apps/<myapp>/Application.mk to describe your application
and the native sources it needs to the NDK build system

5/ Build your native code by running "make APP=<myapp>"
in the top-level NDK directory.

你把NDK仔细看看就知道怎么弄了～～

[kinghua_q]

我也想知道怎么在mm的时候把so打包到apk中!!!!!!!!

[kofihust]

是我自己写的，参考android的source code里的例子写的。其实NDK也是一样的，只是做了一些简化而已，但是功能还很少，建议直接在源码下编译，比用NDK复杂不到哪里去。另外yili_xie兄问.mk和apk在source中的目录结构，是这样的：.mk文件当然是在根目录下，因为我是在source code下编译的，apk在myandroid/out/target/product/generic/system/app下，其中myandroid为source code的根目录。
其实多看看源码，很多问题都能找到答案

Building a simple 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)

Building a APK that depends on a static .jar file

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)

Building a APK that should be signed with the platform key

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)

Building a APK that should be signed with a specific vendor key

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)

Adding a prebuilt 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)

include $(BUILD_PREBUILT)

Adding a Static Java Library

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)

找到点相关资料，现在只试了使用jar库，可以使用。

非常感谢各位！
