android关于jni反射的一些操作

方法如下：
1.添加如下代码在MainActivity类内static {System.loadLibrary("hello_jni");}public native  String getstringfromC();
2.打开终端，android studio已经提供了终端
3.首先进入java目录执行命令：
javah -d ../jni  com.example.root.ndk_sample.MainActivity
com.example.root.ndk_sample.MainActivity是native函数的所在的包名和类名，中间使用“.”号分开
4.添加*.c文件在jni目录中
5.编写Android.mk和Application.mk 放在jni目录下面
6.Android.mk文件的内容如下：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE :=hello_jni
LOCAL_SRC_FILES := hello_jni.c
include $(BUILD_SHARED_LIBRARY)
Application.mk 文件内容为：
APP_ABI := all
APP_OPIM :=debug

1:在环境变量path中配置例如“E:\work\java\android-studio\jre\bin”的路径才能用javah生成jni用的头文件。
2：在C:\Users\zhuweigang.DS\Desktop\LvsAndroidPlay\lvs_androidjni\src\main\java目录下（和com同级目录）输入：
“javah -d ../../jni com.example.lvs_androidjni.LvsAndroidInterfaceFFmpegDemux”即生成和mian同级目录的jni里面包含jni的头文件。
3：下面就用到ndk编写c的程序然后生成so，需要编写android.mk，Application.mk等等。

4：编写好android.mk和Application.mk，在同一级目录输入“ndk-build”生成.so。

5：可以用 " nm -D libLvsOpenal.so |grep interface_1init"查看是否有输出，其中“interface_1init”是javah生成的那个头文件里面的函数名称所包含的关键字。

如果成功了则显示如：

0000cf18 T Java_com_example_lvs_1androidjni_LvsAndroidInterfaceOpenAl_lvs_1openal_1interface_1init。
