Android系统external层集成第三方静态库.a文件经验

系统android5.1，已有第三方静态库libstatic.a，头文件libstatic.h，调用文件main.c。

步骤如下：

1、external下创建文件夹lib_test(名称根据自己实际情况设定)；

2、将第三方静态库libstatic.a，头文件libstatic.h，调用文件main.c复制到external/lib_test下；

3、编译android.mk

参考如下：

LOCAL_PATH:= $(call my-dir)

#-----------------------------------------------------------------------------
include $(CLEAR_VARS)
LOCAL_MODULE := libstatic
LOCAL_MODULE_CLASS :=  STATIC_LIBRARIES
LOCAL_SRC_FILES := libstatic.a
LOCAL_MODULE_SUFFIX := .a
include $(BUILD_PREBUILT)
include $(PREVUILT_STATIC_LIBRARY)
#-----------------------------------------------------------------------------

-----------------------------------------------------------------------------

include $(CLEAR_VARS)

LOCAL_C_INCLUDES:= $(LOCAL_PATH)
LOCAL_SRC_FILES := ./main.c

LOCAL_SHARED_LIBRARIES := \
    libcutils \
    libutils \
    libbinder 

LOCAL_STATIC_LIBRARIES:= libstatic
LOCAL_PRELINK_MODULE := false
LOCAL_MODULE_TAGS:= optional
LOCAL_MODULE := main
include $(BUILD_EXECUTABLE) 

4、最重要的一步：

在out\target\product\rk322x_echo\obj\STATIC_LIBRARIES下创建文件夹libstatic_intermediates

没有这一步会出现：

5、复制libstatic.a到libstatic_intermediates，同时从\rk322x_echo\obj\STATIC_LIBRARIES下其他文件夹内复制export_includes、import_includes文件到libstatic_intermediates

没有这一步会出现：make: *** No rule to make target `out/target/product/rk322x_echo/obj/STATIC_LIBRARIES/libstatic_intermediates/export_includes', needed by `out/target/product/rk322x_echo/obj/EXECUTABLES/main_intermediates/import_includes'.  Stop.

OK了
