android – 重用arm共享库

>我有* .so文件形式的预编译库. (例如lib1.so,lib2.so等),
它带有一些标题.
>我创建了一个模块,它通过包含头文件和* .so文件来利用预编译库.在示例中,我将其称为“libtestwrapper”.该模块定义了自己的源文件,并可选择包含.如下所述,可以为第二个模块导出模块功能(如果提供头文件).
>我创建了第二个模块(newModulE),它将第一个模块(libtestwrapper)添加到’LOCAL_SHARED_LIBRARIES’中.这使得先前导出的头文件(在’libtestwrapper’中)可用于’newModule’.

这是我的Android.mk的内容：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := libtestwrapper
LOCAL_SRC_FILES := libtestusage.c # Use the methods of libtest.h here
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include # This is where libtest.h should be

# provide this line if you intend to export any header files to another module
#LOCAL_EXPORT_C_INCLUDES += $(LOCAL_PATH)/include # you may also use a different directory than 'include'

LOCAL_LDLIBS := -L$(LOCAL_PATH)/dir_with_libtest_so -libtest # -llog etc.
                                #optionally add any as needed: -llog -ljnigraphics -lz -ldl -lgcc
                                # '-libtest' corresponds to 'libtest.so' - the names must match
                                # -llog is for logcat for example
include $(BUILD_SHARED_LIBRARY)

# Optional:
# Define a second module wich is making use of the first one (i.e. libtestwrapper)
include $(CLEAR_VARS)
LOCAL_MODULE := newModule # this module will be making use of the first one (if needed)
                    # Add local source files. If the files are stored in directories
                    # you have to provide a relative path  starTing inside the 'jni' directory.
                    # The example is for this structure: jni/dirTosourceFiles1/*.cpp
LOCAL_SRC_FILES := dirTosourceFiles1/sourceFile1.cpp dirTosourceFiles1/sourceFile2.cpp
LOCAL_C_INCLUDES += $(LOCAL_PATH)/newModule_include # path where the headers of this module are stored
LOCAL_SHARED_LIBRARIES += libtestwrapper # make use of the prevIoUs module

# Optionally add this line if any other libs should be used
#LOCAL_LDLIBS := -llog -ljnigraphics -lz -ldl -lgcc
include $(BUILD_SHARED_LIBRARY)
